We’ve heard a lot of buzz about Think Thin Bars. Our in-depth review focused on the ingredients, side effects, and clinical research. Furthermore, we examined hundreds of user comments and testimonials. Then, we summarized and condensed to give you all the info you need.

Think Thin Bars Readers: Click here to find out why we're giving away samples of our product, Burn HD.

What are Think Thin Bars?

First off, Think Thin Bars are meal replacements and snack products. [1] The ingredients are:

  • Whey/Soy Protein Isolate
  • Hydrolyzed Collagen
  • Maltitol
  • Cocoa Butter
  • Chocolate Liquor

Other ingredients include dairy oil, calcium carbonate, lecithin, vanilla, hydrogenated starch hydrolysate, glycerin, peanut butter, peanut flour, natural flavor, salt, mono and diglycerides, lecithin emulsifiers, vitamins and minerals. You can eat them on-the-go or as a substitute for breakfast, lunch or dinner.

Think Thin Bars is one of the first items from Think Products ; a company started in 2000. Local grocers and the official website sell the supplement. We like the longevity of the company, and that we found some positive customer comments, but read on…

Side Effects – “Negative or Positive?”

Our first concern is with Think Thin Bars side effects. “If you regularly eat them as an alternative to meals or unhealthy snacking, your body with undoubtedly appreciate the reduction in sugar,” said our Research Editor, “But the sugar alcohols in them may have a negative effect on your stomach.” [2][3]

“A girlfriend of mine told me that these bars caused her excessive flatulence. I didn’t believe her till I tried one,” said one user.

“Since I have been eating these, I notice major gas issues, bloating and minor diarrhea. I do not have a lactose allergy as far as I know since I can eat dairy problems without these symptoms,” said another.

On the other hand, we found reviews of Think Thin Bars with a different take on side effects.

“No issues with my stomach like others are saying,” commented a customer.

Think Thin Bars Ingredients – “High Calorie Count?”

Another fact that we found in Think Thin Bars reviews was the relatively high calorie count. [4] “Too dense and calorie-laden,” said one customer online.

“At 230 calories per bar (with 8g of fat – 12% of DV), you may ‘think thin’ all you want, it’s just not gonna happen,” said another.

While some dieters complained about the calorie count, others didn’t mind, considering some use it as a meal replacement.

“Sorry, I don’t count calories. It gives me the nutrients needed,” said one person.

“I don’t count calories, as long as it fits my macros,” reported another.

Our research has shown that if there is a significant drawback with a product, the likelihood of long-term success is slim. There’s an issue if customers have concerns with the high calorie count of Think Thin Bars.

The Science – “Any Real Proof?”

From a scientific perspective, the sugar substitute maltitol isn’t as bad as other choices. [6] The National Library of Medicine has a number of published studies pointing to gastrointestinal side effects related to maltitol, but the flatulence and abdominal pain are more discomforts than dangers. [7] The high calorie count, however, doesn’t make these a friend to dieters. Losing weight is a simple process: burn more calories than you consume. [8] ThinkThin bars seem more suitable to athletes needing the high-protein impact rather than to average people trying to burn a few pounds. [9]

What Users Are Saying

“I have been eating Quest Bars for a year and needed something new. I tried these Think Thin bars and they are WAY better than Quest bars. They have a coating over the whole bar and they are much softer than Quest bars. Now I eat these every day. Lemon is my favorite so far but the chocolate ones are amazing as well.”

“There isn’t anything wrong with these other than that I didn’t like the taste. I was looking for a non-protein tasting protein bar and these were not it. Unfortunately I won’t be ordering these again – But at least my husband will eat them so they won’t go to waste.”

“This flavor is really gross. I’ve had the chocolate peanut butter and that flavor is really good. But this one is just nasty.”

The Bottom Line – Do Think Thin Bars Work?

What are our final thoughts on Think Thin protein bars? We like the longevity in the market and the positive feedback we saw online. But, we have reservations about the bars as they relate to weight-loss. The high calorie count could be a detriment to dieters, and the sometimes-intense abdominal discomfort associated with that much protein and maltitol may discourage someone trying to trim down. [10]

If you are trying to lose a few pounds or get a little bit more trim, you should probably look for a product that won’t make you gassy and bloated. Also, your supplement shouldn’t add to your daily calorie intake.

Among the best products we’ve seen this year is one called Burn HD. The supplement contains four clinically-tested ingredients, which have been shown to possibly help burn fat and boost metabolism. Online reviewers are thrilled with its performance, and there’s no talk about harmful side effects.

Also, the company behind Burn HD is so confident in their supplement, that they’re offering customers a 2-Week Sample.

Think Thin Bars Ingredients

Think Thin Bars Ingredients and Supplement Facts

Serving Size:
Serving Per Container:
Amount per Serving% DV

Other Ingredients: None

After thoroughly investigating the Think Thin Bars ingredients, we provided the specifcs you really need.

Whey Protein Isolate

To start, whey protein isolate is actually a by-product of cheese manufacturing. It’s also available in concentrate and hydrolysate forms. Often this ingredient is free of fat, cholesterol, carbohydrates and lactose. It’s commonly used in protein powders, shakes and bars.

What is it Supposed to Do?

Typically whey protein isolate is included in supplements to help build lean muscle mass. It’s also intended to boost energy levels and reduce appetite. It can be consumed in place of foods that are high in fat and calories. This may aid with weight-loss.

Clinical Research

According to research posted on the Mayo Clinic website, “Overall results suggest that whey protein may promote better weight-loss when compared to lower-protein diets.” [1] Therefore this ingredient may be beneficial to those trying to shed excess pounds.

Clinical testing is very important if you’re trying to pinpoint a diet supplement that actually yields results. This is why you may want to take a look at Dietspotlight Burn. It contains ingredients that have been researched.

Soy Protein Isolate

Firstly, soy protein isolate is essentially taken from soybeans. It’s a non-animal source of protein that is used in countless shake powders and bars. Also, it’s low in calories, and free of cholesterol and saturated fat.

What is it Supposed to Do?

Like whey, soy protein isolate is intended to curb hunger and elevate energy levels. It’s also supposed to help with muscle building and overall fitness. Furthermore, it should not raise blood glucose levels or cause any cardiovascular problems.

Clinical Research

While soy protein isolate may not directly cause fat loss, it has been linked to certain health benefits. For instance, The University of Maryland Medical Center says, “Studies suggest that soy protein may reduce the risk of heart disease by lowering levels of LDL (bad) cholesterol. For example, in a clinical study of nearly 5,000 men and women living in Japan, those who ate the most soy had the lowest cholesterol levels.” [2]

Calcium Caseinate

Okay, calcium caseinate is a protein that’s used in all kinds of creamers, instant soups and supplements, including shakes and bars. It’s derived from the casein in milk. It provides amino acids to benefit the muscles.

What is it Supposed to Do?

Generally calcium caseinate is added to supplement shakes and fitness products to help improve lean body mass and reduce appetite. It may be used in meal-replacement drinks and bars to help you reduce your overall calorie intake as well.

Clinical Research

There is some solid research that supports calcium caseinate for weight management. One study published in 2013 in the “Journal of Sports Science and Medicine,” revealed that “Women who supplemented with casein for eight weeks and completed their usual workouts experienced a “significant” change in body composition, losing more body fat than they had previously.”

Is There Anything Out There That We Think TRULY Works?

We did find one supplement that stands out. Dietspotlight Burn, which contains powerful ingredients that HAVE been clinically tested, may be a good option. Note that all customers can take advantage of a Special Trial Offer, that’s available. Click above to give it a try.

Previous Think Thin Bars Review (Updated September 20, 2012):

Think Thin Bars: What You Should Know

Think Thin Bars, manufactured by thinkThin, are marketed as a protein bar that promotes weight loss and increases energy. It is suggested that these bars be used as a snack replacement and perhaps to replace either breakfast or lunch. Think Thin Bars seem to be targeted to male bodybuilders, but they are said to beneficial to any adult wanting to lose weight or increase energy regardless of gender, age or fitness level.

The website for Think Thin Bars provides very little information on them. There are no user testimonials posted and there is no evidence posted to prove that they can do what they are advertised to do. Those wishing to try Think Thin Bars can do so without a prescription because they are considered food.

List of Ingredients

Vitamin A, Calcium, Calcium Caseinate, Whey Protein Isolate, Soy Protein Isolate, Hydrolyzed Collagen, Maltitol, Cocoa Butter, Chocolate Liquor, Calcium Carbonate, Dairy Oil, Lecithin, Vanilla, Hydrogenated Starch Hydrolysate, Glycerin, Peanut Butter, Peanut Flour, Natural Flavor, Salt, Mono and Diglycerides, Lecithin Emulsifiers, Tricalcium Phosphate, Vitamin C, Vitamin E, Niacin, Iron, Zinc, Pantothenic Acid, Vitamin D, Vitamin B6, Copper, Riboflavin, Thiamin, Folic Acid, Biotin, Iodine and Vitamin B12.

Think Thin Bars: Product Features

Think Thin Bars come in a variety of flavors such as Caramel Swirl, Chocolate Fudge, Crunchy Peanut Butter, Creamy Peanut Butter and Brownie Crunch.

Advantages of Think Thin Bars

  • Think Thin Bars are now available at a reduced price.
  • This product contains several essential vitamins and nutrients.
  • Think Thin Bars are free of gluten, sugar and wheat.

Disadvantages of Think Thin Bars

  • There are artificial flavors in Think Thin Bars.
  • Those with a peanut allergy should not use this product.
  • Anyone taking certain medications or with certain medical conditions should consult a physician before consuming this product.
  • Think Thin Bars contain a high amount of calories.
  • There is no research cited to prove the effectiveness of this product.
  • There are no user testimonials posted for this product.
  • Those with lactose intolerance may not be able to consume Think Thin Bars.


Think Thin Bars do not really stand out from the rest of the supposed snack and meal replacing weight loss products available today. Think Thin Bars may not be an effective weight loss product because there does not seem to be any proven appetite suppressants or fat burners in it so those seeking a weight loss supplement with the ability to suppress the appetite and burn fat may want to research other products that are intended for appetite suppression and fat burning. Those seeking weight loss may also benefit from developing a healthy diet and exercise program that suits them and their lifestyle. Users will need to assess their health and fitness goals and decide if using Think Thin Bars is right for them.

91 Think Thin Bars Reviews

  •  My experience with Think Thin is pretty great!
    Brock (Verified User)

    Fortunately, I have not experienced the gastric issues some have after eating Think Thin bars. I have one for lunch at work during the week days. Just easier to throw one in bag each morning and eat at my desk– and it doesn’t give me the after lunch “crash” that a heavier meal would. Can’t be drowsy when there’s still work to be done! I have lost 31 lbs since beginning my weight loss journey in early March 2017. (264 lbs around first of March to 233 in mid June 2017, and still losing).

    Now, of course this isn’t all I eat. My breakfast most mornings is two tablespoons of peanut butter and a banana with one cup of milk or I’ll have a scrambled egg patty and turkey sausage patty with a slice of real white cheese on an Orowheat sandwich thin roll. Dinner is usually a serving of quality meat– beefy, poultry, pork– with steamed veggies and maybe some brown rice.

    I’m happy to be losing weight, I feel wonderful and not deprived. I have to think that the Think Thin bars, along with sensible eating at other meals and logging calories with MyFitnessPal, help keep my calories in check.

    Good luck on your own journey! 😀

  • Your Namepat brandeberry

    Do all of the bars have chocolate and milk in them?

    • Veronica

      Hi Pat! For details on ingredients, please refer to our ‘ingredients; tab for more information.

  • what about the alcohol sugars?
    patti vopnford

    What about the alcohol sugars?? What on earth are they? very confusing.

    • Cindy

      Sugar is sugar… it is what is used in a lot of “no sugar” products… but sugar is sugar. BUT… the chocolate has Chocolate Liquor… this contains sugar!

    • Sammy (Editor)

      Hi Patti! Sugar alcohols come from plant products that are altered chemically to provide less caloric sugar substitutes. Even if a product claims it’s ‘sugar-free’ it does not mean the product is free of sugar substitutes. A dietary supplement to keep in mind, that is really free of sugar substitutes, and definitely helps you lose weight is Dietspotlight Burn.

    • Dianna

      they do something to sugar and call it sugar alcohol. Sorry I can’t explain it so well

  • Kayla

    I’ve been eating these for about a week now, I go to the gym for like an hour everyday and I just eat them for breakfast everyday and then eat greens/chicken and stuff for lunch/dinner. Will this help me lose weight? I’m 5’2 and 130 pounds and am trying to lose some belly fat and tone up. Really need to know so I’m not wasting my money or start gaining weight!

    • Kayla

      Thanks! I just came across this website again and didn’t even remember I commented 😂 I still eat them for breakfast and i feel they are a good meal replacement! Thanks for the advice! And yeah, the no sugar thing was a deal breaker for me! It’s just kind of discouraging seeing all of the bad reviews, but I think I’ll stick to em. ☺️

    • Victoria (Editor)

      Hey Kayla. All users are different and can experience different weight-loss results.

  • Is it be a healthy breakfast?
    Stacey (Verified User)

    I’m not trying to lose weight. I’m just trying to eat healthy. Sometimes I don’t have time to make a healthy breakfast. Is thinkThin good for a healthy breakfast? Could it cause you to gain weight?

    • Nathalie

      Think Thin bars are great for breakfast. I eat one everyday on my way to work and they keep me energized and full until lunch time. They do not cause you to gain weight.

    • Lynn

      I’ve recommended these bars to so many friends. My next goal is to have the local WM superstore carry it as only one carries it and sells it for $1.53 while Whole Foods sells it at $2. I’ve been eating the creamy peanut butter bar every weekday morning for breakfast and it literally keeps me full for 3 hrs. I remember my first time trying this bar…I wasn’t even halfway through that I already felt a sense of “full”

      • Your Name

        I think they are great! I eat them when I’m craving dessert, they are rich and sweet.

    • Sammy (Editor)

      Hi Stacey! All users are different and can experience different weight-loss results, but exercise in conjunction with a healthy diet and supplements have shown to help with weight-management.

  •  I love think thin bars !
    Sara (Verified User)

    i absolutely love think thin bars! However, after I eat one, my whole entire body itches uncontrollably. I couldn’t figure out what was doing this. I was feeling just fine today, had one with my evening tea, and BAM within 10 minutes, I was downing Benadryl and slathering on hydrocortisone cream! It dawned on me, this is what it was!!!

    Anyone have this side effect?

    • Leah

      I get the same affect when I eat them, ten minutes after I’m itchy like crazy but I’ve had all the ingredients at one point of time or another. So I can’t figure it out. No food allergies that I know of.

    • Sammy (Editor)

      Hi Sara! Please make sure to consult with your physician before continuing to take this product and let them know about the side effects you are experiencing! Best of luck!

  • Natural Vitamins OR Synthetic
    James Milligan

    I can’t seem to find out whether or not think thin has natural vitamins or synthetic?

    • Sammy (Editor)

      Hi James, after some research we’ve discovered that although some products are labeled as “natural” and “healthy” they many of the vitamins are in fact synthetic. You may also consider Dietspotlight Burn that is packed with ingredients with strong clinical support and has proven to curb appetite.

      • Debbie

        I eat the Think Thin bars all the time. Well, I mean everyday. I eat them for my lunch along with a yogurt. They taste better than any other protein bar I have tried and I have tried a lot of them. I really like the peanut butter ones. I am on a low carb, high protein diet. I think these are the best.

  •  confused about the Think Thin bars
    Lo (Verified User)

    I’m confused about the Think Thin bars, althought it states NO SUGAR – what about the SUGAR ALCOHOL that has 16g, sugar is sugar regardless of how is labeled. Also have you noticed the CARBS ???????

    I bought this and am going to return………

    • Liela

      I have gestational diabetes. Per my dietary instructions I can have a 2 carb snack which is 30g of carbohydrates. The bars I have, lemon cream pie flavor and chocolate only have 20g of carbs, that is not bad at all. I am not sure what the beef is, but the 15g of protien is very good compared to other bars with less than 9 grams. The price is good too. I have not had any problems using these as a snack. They do not affect my blood sugar level and I highly recommend them.

    • Sammy (Editor)

      Hi Lo! For detailed product information like nutrition facts, please refer to the Think Thin official website for more!

  • Agi

    wow recently I am having gas also but never thought putting it together with this bar. I ll stop having them and curious of the result. Thanks for this article.

    • Sammy (Editor)

      Hi AGI! Please make sure to consult with your physician before continuing to take this product and let them know about the side effects you are experiencing. Good luck!

  • Violet

    These give me EXTREME gas. I had to cancel going to a partly last night because the side-effects of these bars made me not nice to be around. I’m also hugely bloated. Ugh. Next time, I’ll stick to eating chicken and bananas.

  •  Not a Fan
    sherri (Verified User)

    Just tried my first bar, not a fan! I tried coconut almond, did not taste good. Way too many ingredients for me.

  • Your Name

    I don’t like the texture or the taste. It is like eating something that is not edible, almost as if I’m eating playdough. And it gives me stomach aches.

  • Lisa

    after gastric sleeve surgery, I need to consume lots of protein. Getting off sugar was hard to do! Think thin bars did the trick! They fill me up totally, and I can eat 2 bars a day as meal replacements. Then I can eat a good protein packed dinner and be fine. I love the taste and texture and I do not have the gas others have experienced. They are perfect for me, as opposed to other protein bars that have 30+ grams of sugar.

    • Pam

      I agree, Think Thin work great for me. I don’t crave sugar and fat like I have in the past. It fills me up and satisfies as a meal replacement. Down 8 lbs and still on track.

  • Michelle

    I started to eat these because compared to the other protein bars they do not have the excessive sugar. I do not have problems as far as the gas issue is concerned. I eat well, exercise, and it helps that my job makes me walk at least 4 miles a day. These protein bars allows me to get my protein in for the day without the crap that is associated with some protein bars.

  • Mary

    I tried these bars because I had developed a really bad habit. Each morning I had to have something sweet with my coffee. Cake, cookie, anything. I was able to break the bad habit with these bars. I only needed half of one with coffee and used the other half later as a treat. No side affects whatsoever and it helped me beat my extreme sugar addiction. I love the creamy peanut butter the most. It has a chocolate coating and the inside has sort of a marzapan consistency. Just love ’em!

  • bumblebee

    I love think thin bars! I have no side effects at all, and i add them daily as 2 meal replacements for breakfast and lunch. For dinner i eat almost carb free and sometimes as a snack low fat quarkcheese or a few almonds. These combo seems awesome for weightloss. I absolutely love the taste from think thin bars and makes me quite full. My favourite! I also like the quest bars, but i don t like the aftertaste so much and it doesn t keep my satisfied for hours. So think thin bars are the way to go for me.

  • Andrew

    I like the bars for the most part. Leaves a somewhat strange ‘coating’ on my tongue, I feel like; maybe because of the sugar alcohol rather than regular sugar? I was kind of duped by the ‘sugar-free’ here, as the sugar alcohol content is pretty high, but it’s ‘better’ than regular sugar from what I’ve read on diabetes websites (FYI, I don’t have diabetes, just did some research). I do feel like these are a good substitute for the ‘regular’ sugar protein bars, however, in terms of gut feeling/reaction. Sugar wreaks havoc on my belly… Switched from normal fruit-flavored yogurt to plain greek and that made a world of a difference.

    No gut problems from them as far as I’ve noticed. Eat them on work-out days/mornings for breakfast after a fruit. I tend to do the high fat, high fiber, try to be low carb as possible, as little sugar as possible, high protein approach (somewhat keto, but not full on).

  •  I use them for energy not weight loss !
    April (Verified User)

    I use think thin bars as a way of getting energy for my runs. I have been eating them for over a year now. Coupled with exercise these things work great. If your not planning on exercising to lose weight then they might be too high calorie. For what I use them for (energy) they do the trick. The gas and bloating. I guess that is a side effect I have experienced and I had no idea that’s how I was getting it. I guess I will have to look for another bar that doesn’t have the ingredients that cause this, darn it!

  • I don't like a lot of proteins

    I don’t like a lot of proteins, meats etc.,so I’ve been taste testing lots of protein bars and shakes in the past few months. Have yet to find a shake that doesn’t taste like vomit and I feel the same about most of the bars but this one is the best hands down. I have only tried the peanut butter/chocolate and the chocolate fudge, can’t decide which one is better! My only confusion is with the sugar, there are different forms of sugar besides high fructose corn syrup so I wouldn’t say these are 100% sugar free. But I’m eating them strictly for the protein.

  • Rita

    This was the most nasty thing I have ever eaten. Actually, I didn’t even swallow it, it was so horrid.

  •  They taste great
    Debbie (Verified User)

    I think they are great! They taste good and they have a lot of protein in them and that is what I am going for. Low carb, high protein. Although they do have a lot of carbs in them, 22 grams, but I am not sure if it is the good carb or the bad carb. I eat them for my lunch, everyday.

  • Side Effects

    The Think Think bars taste superior to other protein bars but since I have been eating these I notice major gas issues, bloating and minor diarrhea. I do not have a lactose allergy as far as I know since I can eat dairy problems without these symptoms. Taste wise they are great but the side effects will keep me from buying these again.

    • Your Name

      Try a quest bar!!!

  • I don't feel hungry for hours.
    Melinda P

    I think these bars are super yummy. I don’t feel guilty eating them when I want something chocolaty to sink my teeth into. Afterwards, I don’t feel hungry for hours. They make a great snack to keep in your desk at the office!

  • artificial sweetner Malitol

    To one of the reviews that wondered what sugar alcohol was…it is the artificial sweetner Malitol. It will bloat you up with gas and make your stomach hurt really bad. I don’t understand why this company can’t use Xylitol or Organic Stevia instead…totally beyond me. Why are they called Think Think? when the calories are high,fat grams are high, carbs are high and then top it off with a nasty fake sweetner to make our stomachs hurt. I tried to see the ingredients on some of the bars and there is NO link, just the calories, etc. It’s not worth wasting valuble money to feel bad. Sorry, I give 1/8 a star vote, please improve the sweetner.

    • Nicki

      Thank you for posting this. 🙁

    • Js

      I get absolutely NO gas reactions from these products…I don’t use as a diet bar or meal replacement…just a low sugar snack for a choco craving

  •  I love these.
    Svetlana (Verified User)

    I love these. They just came out with the crunchy nuts version. They keep me full for a few hours and I love the texture of biting into them. Kinda like a candy bar texture. My fav is the Chocolate fudge.

    • Nina

  •  Stay away, or you're gonna blow up and smell!
    sam (Verified User)

    Yes, they taste great. There is just one big problem that I have with them. They bloat me and make me pass some nasty gasses. I mean it is annoying. I don’t want to fart all day long and stink up the places. And that’s how bad they are, especially the Think Thin + Fiber. Stay away, or you’re gonna blow up and smell!

  •  I would buy it again.
    Yolana (Verified User)

    I bought the brownie crunch Think Thin bar on the fly because I needed a protein bar. My intention was not for weight loss. I also liked the fact that it was gluten free. It was tasty. I am lactose intolerant but this bar did not give me any problems. I would buy it again.

  •  Loved the product.
    Anonymous (Verified User)

    the no sugar is impressive, but there is only two grand of fiber? and they taste nastyand have more calorie than my diet allows. I eat half a/ raw fruit or veggie. I use them and slim fast, and special k, and kind bars.i have lost nine pounds in three week. that’s as a meal replace in the slim fast plan.

  •  Loved the product.
    Rachel (Verified User)

    YUM!!! The Creamy Peanut Butter tastes delicious!! Eating one as I write this… First time trying, so I don’t know if there are any weight loss-benefits yet. All I know, is it tastes batter than any bar I’ve ever tried, no sugar, and I’m already full and not even through the whole bar yet. I’m excited to try other bars.

  •  I love these bars!
    Jenine (Verified User)

    I have been eating a think thin bar for breakfast everyday for the past couple of years. The creamy peanut butter is my favorite and it satisfies me for 3-4 hours… I have always eaten a low glycemic diet, exercised daily, and have maintained my weight with the help of these bars. Sometimes I even have one before i go to bed if I’m craving something sweet! I order in bulk through the company every few months. I love these bars as well as Quest bars and Kind bars.

    • Deb

      I agree with what Jenine wrote and am on the same regimen.

        I eat the creamy peanut butter think thin bar for every lunch for the past year. I love it! I exercise a lot, maintain a healthy diet so this bar works perfect for me. I do every once in awhile get bloated but its manageable.

  •  Good ingredient list and flavor
    Stephanie (Verified User)

    “Think Thin Bars do not really stand out from the rest of the supposed snack and meal replacing weight loss products available today.”

    I don’t understand how you can make that assertion. Think Thin bars do not have any sugar in them whatsoever. This is a huge difference from most snack and meal weight loss products. Especially when they are compared with other protein bars, which sometimes have up to 25-30 grams of sugar in a single bar.

    I agree with other users who praised these bars for their ingredient list and flavor as well. They also have significantly higher amount of protein than the average protein bar (two time as much as the typical protein bar).

  •  Very satisfying and delicious!
    Marie (Verified User)

    LOVE these bars. So hard to find anything without sugar and they are both delicious and satisfying. I’ve been enjoying the chocolate fudge and have no complaints. They keep me full for hours and are supporting my weight loss goals. Anxious to try the other flavors.

  •  This product taste so good
    Buddy (Verified User)

    I bought these bars on a lark. I have eaten just about every protein bar out there. These bars were so good, that I looked them up to buy in bulk. They were a great snack for me because I’m on the road alot and most stores carry junk bars loaded with sugar. I wanted a good balance. These buys surprised me and the taste was good compared to other protein bars. I would like to see more of a whey protein, but the soy will be o.k.

  •  Tried the product and looking for result
    Jara (Verified User)

    A girlfriend of mine told me that these bars caused her excessive flatulence. I didn’t believe her till I tried one…

    • DancingVeggie

      I thought it was just me! I was passing the GROSSEST gas and could not stop pooping! Ugh.

      • Momma

        It’s the sugar alcohols that cause the gastric issues, the gas and diarrhea.

  •  Love these bars
    Holly (Verified User)

    Love these bars! I have to eat low glycemic, and it’s hard to find something for on the go. I eat half for a snack and the other half right before working out. They hold me over and help keep my blood sugar on target.

  • Think Thin Bars

    Does it actually help you loose weight?

    • Anon

      Not sure if they help you lose weight, I eat them a lot though.

    • Your Name

      Protein bars are not intended to help you lose weight really. These bars have 240 calories in them. These can be use as diet supplementation or meal replacement. For example, I eat up to 7 small meals a day and always include a protein source. While real protein sources are best (chicken, fish, lean meat, egg whites), sometimes we don’t always have these readily available. I use these as one of my meals alongside of a raw veggie. If you are looking to restrict calories, I would eat a half a one alongside a veggie, as someone suggested.

      Hi Anon! All users are different and can experience different weight-loss results, but exercise in conjunction with a healthy diet and supplements have shown to help with weight-loss.

  •  Take refined sugar out of your diet
    Lindsay (Verified User)

    Those of you that think it tastes gross, I’m going to say you consume a lot of sugar and/or lots of processed foods. Take refined sugar out of your diet completely and you’ll start to taste food again, for real. These bars taste great and are very sweet tasting to me, and appreciate the no sugar added. They are good for protein which helps supress appetite, but not recommended after a heavy weight lifting session at the gym. You shouldn’t have fat right after you lift. Give it a half hour/hour and then yes, fat is good for you. Well, you know what I mean – good fats, in moderation and in balance with carbs & proteins.

    • Larissa

      I totally agree with you!! I just ate my second bar just as I was reading your post! I’m on that time of the month and I was craving chocolate so bad.. Bought a couple bars from different brands and this one is by far the best when it comes to flavor and sweetness I don’t consume sugar on a regular basis so I found them very sweet!! Perfect to trick my mind 🙂 .. I don’t know if I would eat them on a regular basis because they do have a lot of calories.. But in special occassions I would totally eat them.

  •  I love the taste of Think Thin bars
    Rick (Verified User)

    Maybe it was that scarring week I spent at the Optimum Health Institute eating sprouts and drinking wheatgrass juice, but I love the taste of Think Thin bars. Aside from the “Natural Flavors” (which is who knows what), I am impressed with the ingredient list and the balance of macronutrients (proteins, fats, and carbs). Potassium iodide is even included, which is wonderful for our iodine-deficient society, scourged with high levels of subfunctioning thyroids and thyroid syndromes. That may be one reasons why these bars are promoted as weight loss and energy bars because the thyroid needs iodine to manufacture its hormones, which regulate the metabolism. Sugar alcohols, like Xylitol, have actually been touted as a form of tooth decay prevention. They are not tolerated well by some people, but for others the lower insulin spike it produces is very desirable. We need some carbs/sugars with our protein so that the body will release insulin and drive the protein into the muscle cells. As far as flavors go, I’m partial to peanut butter, not a big chocolate fan. The lemon ones are pretty good, too.

  •  Enough of that
    craig (Verified User)

    my wife and I really like these bars. they are low carb, high protein and low glycemic index so does not spike the blood sugar. These are not candy bars and make a great replacement. We use them as a snack or meal replacement (we try to eat small amounts, 6-7 times a day). The best part about these is that they do not make you crave for more. I eat one and do not need more to eat for another 2-3 hours.
    chocolate mudslide, crunch and chunky peanut butter are the 3 best flavors, though i do like the dark chocolate also (but they have caffeine and I drink enough of that).

  •  pretty much killed my appetite though.
    christina (Verified User)

    im eating the chocolate mudslide right now, and it tastes absolutely disgusting.
    pretty much killed my appetite though.

  •  I give A+ rating.
    connies419 (Verified User)

    I agree with Dawn about the taste, the number of protein grams, and the A+ rating. I’ve had the chunky peanut butter bars, the white chocolate raspberry bites, and the lemon bars, and I liked all three. Considering that 20 grams of protein and the terrific low-GI effect, I think they taste good .. good enough to satisfy my dessert cravings while supplying lots of protein. They are not low-cal, of course, so they’re not an unlimited snack at all. I works good for me to cut them in half and wrap each half in foil or a baggy so I have a mid-morning and a mid-afternoon (10-grams-protein each) snack.

  •  The best tasting bars i ever used.
    Erin (Verified User)

    I’ve tried SO MANY different types of high protein bars for after a good workout, and these bars are the only ones I’ve found that don’t contain ANY sugar, which is a major plus. I wouldn’t use them as a meal replacement, but rather as a protein source after a workout. The taste is definitely something that you may need to get used to, but the fact that they are gluten free is great. Another good bar to try are the Premium Protein bars. They have 30 grams of protein and about the same amount of calories per bar that the Think Thin bars do (around 230). And while the best tasting bars so far have been the Clif Builder Chocolate Mint and Peanut Butter bars, they contain 20 grams of protein and 20 grams of sugar per bar.

  •  Think Thin Bars are the best
    Ivy (Verified User)

    Think Thin Bars are the best I’ve ever had. I have a gluten intolerance and these are allergen free for me. Also, all th eother bars with 20 grams of protein all also full of hydrogenated oils and nasty ingredients which are unhealthy and taste bad. Think Thin Bars are fabulous and delicious!

    • Dawn

      I have only hsd the white chocolate raspberry bites, and I thinkthey are very good. I eat low glycemic, and it is hard to find bars that mmrt the requirements for that. These bars are A+ in my book.

    • Anonymous

      They are da best !! No sugar is de best

    • Your NameKaren

      I have celiac and must eat gluten free. The Think Thin bars have been my go to meal in the go for many years. They also calm my sugar cravings. The white chocolate and the white chocolate macadamia nut are my favorite.
