Don’t laugh, but well over 50% of diet products simply don’t work. So what can this Right Size Smoothies review tell us about diet? We chose to conduct one of our thorough reviews, taking a closer look at the ingredients, side effects, clinical research and customer service. We also pored through hundreds of user experiences. Then, we summarized and refined it all to give you the information you need.

Right Size Smoothies Readers: Click here to find out why we're giving away samples of our product, Leptigen.

What are Right Size Smoothies?

First of all, Right Size Smoothies is a protein-based meal replacement shake. Ingredients include low fat milk, fructose, natural and artificial flavors, gellan gum, sodium citrate, potassium citrate, sodium phosphate, carrageenan, sucralose, salt, acesulfame K, magnesium phosphate, zinc citrate, chromium, biotin, green tea leaf, guarana seed extract, copper citrate, potassium, sodium selenate, white willow bark, folic acid, riboflavin, calcium pantothenate, cayenne pepper and cinnamon twig extract. It is available in a number of flavors including chocolate, vanilla and mixed Berry. Each container provides 20 servings or enough to get through 10 days, using it twice daily. You can mix and go, one benefit.

The official website does not provide any information about when the company was founded. We like that there are several flavors to choose from and that the ingredients are easy to find, but read on…

Hunger and Right Size Smoothies – “Need to Eat?”

The first thing that caught our attention about Right Size Smoothies ingredients is that they may not suppress hunger. “Dieters are claiming they want to eat soon after using the shakes,” says our Research Editor. “That is not part of the equation when you want to lose weight.”

“Within an hour of drinking my shake, I am already hungry. It does not “smash” your appetite. This is great as a snack but not so much for a meal replacement,” said one user.

”The new formula is nothing like the old formula. The taste is different but worse than that this no longer keeps my hunger away. Less than 2 hrs later and I’m hungry again,” explains another.

Customer Complaints – “A Big Problem”

Overall, the website presents a credible company, even featuring a clinical study. However upon further review, we discovered a number of complaints on websites suggesting it doesn’t work and some customers were charged without ever receiving the product. One user said, “I never received my smoothies and the money was taken from my account.”
”I was told it would “smash” the hunger, get rid of the cravings and give me energy. It literally did the exact opposite,” offers another.

According to our research, it takes something tiny, like customer complaints, to deter your chances of long-term success. If Right Size Smoothies free trials do not live up to expectations or promises, there are other products that will.

The Science – “Clinical Evidence?”

Right Size Shakes shows a clinical trial conducted for 12 weeks with an outside testing firm. However, because the study itself was funded by the company, we are unsure as to whether or not the results are legitimate. We at DietSpotlight are looking for proof that this product is better than other meal replacement options. Based on the information provided, that’s not necessarily the case.

The Bottom Line – Do Right Size Smoothies Work?

So, are Right Size Smoothies Weight Loss Shakes the best around? We were initially excited to review this one because it appeared like the shake may be a promising way to reach your weight-loss goals, but we’re not sold on suggesting this one to dieters because the clinical proof is just not there. Plus, we are concerned about customer complaints that claim it doesn’t work.

If you’d like to shed some pounds, we suggest using a weight-loss supplement that gives you not only safe and effective ingredients at an affordable price, but something that reviews indicate provides positive results.

Among the best products we have seen this year is one called Leptigen. It is made with a proprietary blend of four clinically proven ingredients, all of which are known to help support metabolism and boost fat loss. Throughout our research, we were unable to find talk of negative side effects, but we easily found conversations from dieters seeing great results.

We’re happy to see the makers of Leptigen are so confident in their product they’re giving new customers a Special Trial Offer, which is always good.

What You Should Know

Right Size Smoothies weight loss shakes are developed and manufactured by Right Size. The official website advertises these products to be "healthy fast food." Right Size Smoothies are sold as already prepared drinks that come in "SkinniVanilli" and "Chocolate Mousse Reduce" flavors (two servings per bottle and four bottles per package). Unlike some diet programs and supplements, Right Size Smoothies are intended to be meal replacements. Therefore the goal is to actually reduce calorie intake. These supplements aim to suppress hunger throughout the day and assist with overall weight loss. Right Size Smoothies are sold via the official website for $12.50 with a 100% 30-day money-back guarantee (it is unclear exactly if this guarantee applies to empty smoothie bottles, or only unopened products.) The primary active component found in Right Size Smoothies is Appemine (derived from cinnamon twig, green tea and galangal). This ingredient is claimed to "powerfully control appetite." Right Size Smoothies additionally contain vitamins B6 and B16 (both aim to assist with boosting the user's metabolism). These smoothie supplements are stated to contain no Ephedrine. Dieters are encouraged to drink 1-2 servings of Right Size Smoothies each day in place of meals. There do not appear to be any customer testimonials or free trial samples of Right Size Smoothies offered on the official website. Right Size Smoothies' free trial is claimed to contain a variety of essential vitamins.

List of Ingredients

Low fat milk, fructose, natural and artificial flavors, gellan gum, sodium citrate, potassium citrate, sodium phosphate, carrageenan, sucralose, salt, acesulfame K, magnesium phosphate, zinc citrate, chromium, biotin, green tea leaf, guarana seed extract, copper citrate, potassium, sodium selenate, white willow bark, folic acid, riboflavin, calcium pantothenate, cayenne pepper and cinnamon twig extract.

Product Features

Right Size Smoothies are basically meal supplements that endeavors to assist men and women with losing unwanted body weight. These supplements are drunk daily to replace meals and cut calorie intake. Right Size Smoothies aim to boost the metabolism, curb hunger and assist with overall weight loss. Major ingredients found in Right Size Smoothies are Appemine (derived from cinnamon twig, green tea and galangal), vitamins B6 and B12 and various essential vitamins. A four-pack of Right Size Smoothies sells on the official website for $12.50 (eight servings).


  • Right Size Smoothies can be easily and conveniently purchased online through the official website.
  • Right Size Smoothies contain an array of essential vitamins.
  • Right Size Smoothies come in an easy-to-take liquid form, which is typically convenient.


  • There are no customer testimonials offered on the official website.
  • A pack of Right Size Smoothies only contains eight servings, which may not amount to much if some dieters are consuming two per day.
  • There are no free trial samples of Right Size Smoothies offered via the official website so no users have no way to find out if the drinks taste appealing.
  • Some ingredients found in Right Size Smoothies may not be suitable for some individuals.
  • It doesn't appear that a healthy diet or regular fitness regimen are encouraged with Right Size Smoothies.


Overall Right Size Smoothies are a rather interesting and unique addition to the world of dietary supplements. On the bright side, these smoothies keep things simple since they are basically just a ready-to-serve meal replacement. However, the notion that only eight servings come per pack may discourage some dieters. Also, many dieters complain about "not feeling full" after using up their daily calories allotment, and there appear to be no appetite suppressing elements incorporated into Right Size Smoothies. If the Right Size Smoothies official website offered some free trial samples or at least a few customer testimonials, Right Size Smoothies would likely appeal to more individuals.

i used right size smoothie 2years ago with incredible results. Back then they were advertising “made with appemine” . My whole day routine was as follows- vanilla shake for breakfast, two hours later sugar free jello and light and fit yogurt, chocolate shake for lunch, two hours later12almonds, baked salmon or chicken over salad for dinner, sugar free chocolate pudding for dessert. 1hr of cardio on the electrical 5 times a week. That was my exact routine for 1 year and I lost 82 lbs! I went off the routine for a year and a half and only gained back 20lbs. Now I’m going back on the routine because I kno it works however when I called customer service the nice lady informed me that they were no longer using appemine in the shakes. Not sure what will happen without it since it was a main ingredient but I’m willing to give it a try again. I am an insulin dependent diabetic that used to have to take 70 units a day but after the weight loss, I was taken off my blood pressure pills and my diabetic pills. My insulin was also reduced to 10 units. RIGHT SIZE SMOOTHIES and DETERMINED WILL POWER changed my life for the BEST!!!

So if can’t have dairy should not take?

Leigh siddiqi

Not sure where you got the only 8 servings per pack? I purchase it by containers that have 20 servings or 10 days worth of smoothies if you drink 2/day. Purchased online for $23.

Connie Menard

I’m hypothyroid and just wanted to know if someone whose hypothyroid can use right size smoothie

Cameron (Editor)

Connie, only your doctor can give you accurate info on your particular risks.


These so-called weight loss smoothies have more sugar content than an ice cream sundae. If you’re diabetic , stay clear! They are also loaded with sodium.


…I use the product with light Soy Milk followed by a Bottle of Lemon Ginger Water.I do NOT add anything to the shake for FILLER that may be where your mistake is…Twice Daily. I walk a lot during the day and a mini work out in the evening..if you pace yourself you will see the results… I also REFUSED to buy it online at those prices I pay 23 Dollars for a one month supply at CVS….I have no issues.

Can I simply point out what a relief it is to uncover somebody who definitely is familiar with what they’re talking about on the internet. You actually understand how to bring an issue to light and make it important. Lots more people have to look at this and fully grasp this aspect of the story. Simply put I simply cannot believe you aren’t very popular because you undoubtedly possess the writing ability associated with an specialist.
