We’ve hearing a lot of buzz about Tonalin CLA, so we examined the ingredients, side effects, clinical research and customer service quality. We analyzed hundreds of user comments and reviews from around the web. Then, condensed and refined to give you the info you need.

Tonalin CLA Readers: Click here to find out why we're giving away samples of our product, Dietspotlight Burn.

What is Tonalin CLA?

First off, Tonalin CLA is a fat burner. [1] The ingredients are conjugated linoleic acid from safflower oil, gelatin, glycerin, water, caramel color and mixed tocopherols. You’ll take two capsules with your largest meal and another one later in the day. The supplement supposedly burns fat and increases lean muscle mass. One of the benefits is that it’s readily available.

Tonalin CLA is marketed by BASF; a company that was founded in the late 1800’s. It’s available in vitamin stores and through online retailers. We like that conjugated linoleic acid has been studied [2] and that we found some favorable customer comments, but read on…

Tonalin CLA Side Effects – “Cause for Concern?”

The first concern we came across with Tonalin CLA side effects was whether they were positive or negative. “The website states this one is well-tolerated with no adverse events [3],” said our Research Editor. “According to some dieters, that’s not the case.”

“I used this for about a week until I noticed my face was breaking out. After I stopped taking this I noticed my skin starting to get back to normal,” said one user.

“The first 1000 mg I took (on a full stomach) gave me a headache and nausea that lasted until the following day. I’ve never experienced such a thing with any other supplement I’ve taken over the years,” said another.
We can’t say that every dieter had the same experience. One said, “What I like is not feeling any side effects concerning my stomach.”

Another shared, “Tonalin didn’t give me any noticeable side effect at all which really pleases me.”

No Results – “Another Concern?”

Based on Tonalin CLA reviews, claims of weight-loss don’t match user results. “I kept my diet the same and my exercise regiment the same. I’ve taken this product for one month and have not lost any weight [4],” said a customer.

“I started using 1 capsule with each meal as directed. No results after 6 weeks. Started using 2 capsules with each meal. I think I might be losing some fat.” said another. [5]

We did find a few users who saw positive changes. As one experienced, “These help me lose some weight and I noticed an uptick in my metabolic rate,” commented a user. [6]

Another reported, “It uses NO stimulants it will take time to work, at least 6 to 8 weeks. ”

Our research has shown if there is some particular part of a supplement that is especially troublesome, such as lack of effectiveness, the likelihood of long-term success is slim. If Tonalin CLA doesn’t produce results, we question the value of the product to the consumer.

The Science – “Clinical Evidence?”

The official Tonalin website claims this one is “clinically proven”. There are several studies showing the effectiveness of cla. [7] After a bit of digging, we the company stated that studies didn’t evaluate the effects of body fat reduction.  For us at DietSpotlight, we like seeing solid science used to support claims. But, if the findings don’t paint a complete picture, we become concerned.

The Bottom Line – Does Tonalin CLA Work?

So, will you lose weight with Tonalin CLA? Well, we like that it contains natural ingredients and is affordable, but we’re concerned about the science not showing it eliminates visceral fat [8] and not proving the immune system in healthy individuals would improve. [9] We’re also a bit skeptical about this one because customer comments are talking about negative side effects and lack of results.

If you want to enhance your weight-loss, we suggest going with a supplement that’s packed with clinically-tested ingredients, that’s not associated with harmful side effects.

Among the best products we’ve seen this year is our supplement called Dietspotlight Burn. It blends four clinically-tested ingredients, with results often found in publications such as The American Journal of Clinical Nutrition.

Additionally, we’re so confident in our supplement, that we’re offering a Special Trial Offer, which is a great sign.

Previous Tonalin CLA Review (Updated September 17, 2014):

What is Tonalin CLA

Tonalin CLA (Conjugated Linoleic Acid) is a dietary supplement that aims to increase the user's lean muscle mass, while reducing unwanted body fat. This diet product comes from safflower oil and is claimed to hinder "lipoprotein lipase," which is an enzyme that's commonly known for breaking down fat cells in food. This process is supposed to result in less fat being absorbed into the dieter's body, hence assisting with weight loss and remaining thinner. Like many other dietary supplements, Tonalin CLA is intended to be used in conjunction with a healthy, well-balanced diet and a regular fitness regimen. If time-constraints are an issue, Hydroxycut is a thermogenic fat burner intended for men and women to boost the metabolism, increase energy levels and assist with weight-loss.

The key active ingredient incorporated into Tonalin CLA is Conjugated Linoleic Acid. This substance naturally comes from animal foods, meats, safflower oil and dairy products. Overall this diet supplement aims to block unwanted fat from being absorbed into the body. Tonalin CLA does come with a few potential side effects, which can involve diarrhea and/or upset stomach. This diet product can be purchased online as well as in most drugstores and nutritional supplement stores. Tonalin CLA is Ephedra-free and the basic form (Conjugated Linoleic Acid) has been around for over 25 years. As with many other diet supplements, systems, pills and products, the results of Tonalin CLA may vary from user to user. This can depend on factors such as body type, metabolism, diet and how much the user exercises.

Tonalin CLA - List of Ingredients

Conjugated Linoleic Acid is the only ingredient we found.

Product Features

Tonalin CLA is a diet product that can be used along with a healthy diet and regular exercise in order to reduce unwanted body fat. Even with excess stubborn fat, GNC's line of products help with weight-loss. GNC Total Lean CLA and GNC Burn 60 are both fat burners that help with maintaining lean muscle mass, while supporting a healthy body composition. This product endeavors to prevent fat absorption and improve lean muscle mass. The primary ingredient found in Tonalin CLA is Conjugated Linoleic Acid, which often comes from safflower oil. This product appears to be marketed toward men and women who wish to lose excess weight. Tonalin CLA can be purchased in most drugstores, nutritional stores and online. Tonalin CLA does not aim to suppress hunger, boost the dieter's metabolism or burn calories faster.


  • Tonalin CLA can be conveniently purchased in many stores and online.
  • Tonalin CLA is Ephedra-free.
  • Tonalin CLA supports a healthy diet and regular exercise.
  • The active component (Conjugated Linoleic Acid) of Tonalin CLA has been around for over 25 years.


  • The official Tonalin CLA website does not appear to offer a money-back guarantee.
  • Tonalin CLA does not assist with calorie burning or appetite suppression.
  • Tonalin CLA may cause an upset stomach and diarrhea.
  • Some ingredients found in Tonalin CLA may not be suitable for some individuals.
  • Product may cause acne. (See reader comments.)
  • The official website lacks free trial samples of Tonalin CLA.

Tonalin CLA - The Conclusion

Tonalin CLA offers an interesting take on getting rid of unwanted body fat. The notion of taking a supplement that aids with the reduction of fat absorption may sound appealing to some dieters. On the other hand, it would be nice to see more substantial clinical evidence backing Tonalin CLA. Furthermore, Tonalin CLA may be more appealing if the official website offered a money-back guarantee, or at least a free trial of the diet product.

Tonalin CLA is a brand of conjugated linoleic acid sourced from safflower oil. There is some clinical evidence that it could help boost weight-loss. However, not all studies reflect results for all genders or ages. It is sold by various companies with all products using the same name.

We dug deep into the Tonalin CLA ingredients to give you the details you need.


Also known as Conjugated Lineolic Acid[1], Tonalin is a brand of this supplement. CLA is a naturally occurring substance found in animal foods, safflower oil, and dairy products. Supplements like this one are available for those who don’t get enough of it in their diets naturally. This product contains 1,000 mg, and meant to be taken multiple times a day with meals. The average diet supplies anywhere from 15 to 74 mg of CLA daily, so it is easy to see why some may want to consider supplementation.

What is it Supposed to Do?

CLA is supposed to decrease the size of fat cells and claims to block fat from being stored there. It’s thought to also help improve immune function. It is sometimes used to treat high blood pressure, and may be useful in treating hardening of the arteries, making it a heart healthy supplement.

Clinical Research

According to a study published in International Journal of Obesity, “The regain of fat-free mass was favorably, dose-independently affected by a 13-week consumption of 1.8 or 3.6 g CLA/day and consequently increased the resting metabolic rate. However, it did not result in improved body weight maintenance after weight loss.” As such, CLA may help with weight-loss, but for best results, should be included with diet and exercise. And even still, supplementation has also been shown in some studies to cause weight gain[2].

Tonalin CLA Side Effects:

Taking a natural weight-loss supplement doesn’t guarantee you’ll never have to worry about headaches or upset stomach. Even a natural formula has the ability to cause a negative reaction. Tonalin CLA side effects are not common in users, but that doesn’t mean they don’t exist for some.

Skin Irritation

Usually, skin irritation is described as a rash or an itch. It may include sores or bumps, red skin, scaly skin or a burning feeling, as well. [1]

What causes skin irritation?

Skin irritation has several causes, but most commonly, it’s associated with an allergic reaction. It may also be a sign of certain diseases, such as chickenpox or measles.


A sick feeling in your stomach may be described as nausea. It may feel like you’re going to vomit, but nausea isn’t always followed by vomiting.

What causes nausea?

Nausea may be caused by an illness, viral infection, bacterial infection, food, a smell, medication, supplements or a number of other possibilities. At times, it’s caused by food poisoning. The cause of nausea may be easy to pinpoint based on when it occurred.

Upset Stomach

Before the feeling becomes so strong that you classify it as nausea, it may be called an upset stomach. This is a feeling of discomfort in the abdomen, usually associated with the stomach flu or another stomach illness.

What causes upset stomach?

An upset stomach may be a sign of something common, such as the flu, but it could also be a sign of something more serious, such as Crohn’s disease. It may be caused by a foodborne illness, bowel inflammation, viruses, parasites or food-related allergies. [2]


Any type of pain felt in your head is classified as a headache. It may be pain behind your eyes or in your sinuses. There are several different types of headaches and they can range from minor to very serious.

What causes headaches?

Hundreds of things may cause headaches from an allergic reaction to the weather outside. Nerves in and around the head are the cause of the pain. Often, stress, anxiety, lack of sleep, illness or medication side effects are at the root of the pain.

It’s not a guarantee that you’ll suffer from Tonalin CLA side effects, but some users have reported skin irritation, nausea, upset stomach and headaches, among others. It’s always a good idea to check with a physician before starting a new supplement, especially if you’re under 18, on current medication, suffering from a current medical condition or you’re pregnant or nursing.

Tonalin CLA Scientific Abstracts:


There had been 63 participants in the study (CLA, n = 30). Following a period of 12 weeks, when compared to baseline, the body weight, body mass index, total fat mass, waist-to-hip ratio, subcutaneous fat mass, and fat percentage were reduced within the group (P < 0.05). The subjects were stratified by body mass index as well as gender. Body weight, body mass index, waist-to-hip ratio, subcutaneous fat mass had been reduced in 27 of the participants with a body mass index ≥ 27. Levels of total cholesterol, low-density lipoprotein, triacylglycerol, and plasma fasting glucose were elevated. Those of high-density lipoprotein had reduced following 3 months of CLA treatment. The changes that were experienced had not been substantially different from baseline. CLA supplement for 12 weeks in overweight and obese Chinese patients had lower obesity indices, without any obvious negative reactions. [1]

During the final 8 weeks of each 16-weeks diet period, there had been a significant decrease in body mass index while on CLA. Safflower oil (SAF) had no effect on body mass index or on total adipose mass, however decreased trunk adipose mass (P = 0.0422) and also elevated lean mass (P= 0.0432). Safflower oil had also greatly reduced fasting glucose (P = 0.0343) while elevating adiponectin (P = 0.0051). There had been no alteration noticed in dietary energy intake, fat quality, and total fat intake for either intervention in either diet spans. CLA and SAF supplement treatment caused altering effects on body mass index, lean tissue mass, and total and trunk adipose mass in obese postmenopausal women who had type-2 diabetes. The oils may have beneficial effects on weight-loss, glycemic control, or both. [2]

CLA seems to cause fat mass loss as well as elevate lean tissue mass in rodents; however results from 13 controlled studies in human subjects had not discovered sufficient evidence to support CLA’s effects on body weight or promotion of repartitioning of body fat as well as fat free mass. There is evidence building regarding CLA’s effect on mice and humans stating CLA isomer trans-10, cis-12 could produce insulin resistance and liver hypertrophy through redistributing fat depositions which are similar to lipodystrophy. CLA reduces fat in both bovine and human milk. It had been concluded that CLA seems to hinder elevations in body weight and body fat in animals, but CLA isomers which are sued as dietary supplements do not appear to be effective as a weight-loss tool for humans.

I am taking GNC Brand CLA THERMO gel capsules. I cannot swallow the pills, so I just take the liquid out of them. Is there any nutritional value in the capsule itself? I’m not sure if I need to be swallowing the capsule as well.

Victoria (Editor)

Hi! For detailed product and usage instructions, please refer to the Tonalin CLA official website for more information.


I just bought almased meal replacement and Tonalin cla 1000mg. The vitamin shop store suggested to take one capsule of tonalin cla before or with my almased meal replacement. If this ok to take both of these together. Really need a urgent answer, for I would like to start this today

Maribel (Editor)

Hi Linda! Because of possible interactions with Almased meal replacement and Tonalin, please make sure to consult with your physician before taking this product.

  Cause Legs Pain

Can this product cause legs pain???


Hello! I’ve tried this cla a few times now and every time I take it, I wake up the next day feeling VERY stiff, tight muscles and water retention. I’m not going to take this product again! I started taking it to help w fat loss, but I’m going to try a fat burner instead.


I took a different brand of CLA but I was waking up with tense muscles too and throughout the day my muscles were feeling achy and soar. I also got headaches more often, mostly from having a stiff neck I think.

  Can take with hypothyroid meds?

I didn’t start yet Tonalin CLA but I was wondering is there any problem if i take it while im taking medication for hypothyroid?

Maribel (Editor)

Hi Maysa! Because of possible interactions with medications, please make sure to consult with your physician before taking this product.


Maysa,I also have been taken meds for hypothyroidism for over 15 yrs. I just started taken Tonalin CLA 6-7 wks ago. I have adapted to changing my eating habits and workout a few days a week. I haven’t had any problems. I have LOST 11 lbs so far and find that it helps support the general energy I need. At my recent Dr. appt., my blood test came out that my thyroid medication has not been affected. Still within the range of hormone needed. I reccomend for you to give it a try.

That place is literally for a passing fancy street as my family! I’m gonna need to try it out, if regarding nothing other than to acquire new moves for me to do at the gym!!


I too have broken out terribly in hives on my face.I’ve honestly have not had any good results with CLA


I have been taking a powdered form of CLA for three days now. I am taking around 4000 mg a day. But today, I have noticed I have period cramps and spotting like I am getting ready to start my period again and I just got off my period a couple of days ago. I am 45 and I didn’t know how this supplement effects the female hormones. I can tell it is helping with my appetite and can see my stomach shrinking; but it has caused a few pimples, which is not normal for me since I have had very clear skin all my lfe. I really don’t want to stop taking CLA, but I can’t have my periods disrupted because I have really bad ones because I have Endometriosis and PCOS. Has anyone else experienced what I am going through??


I thought I was nuts. I first started with CLA back in March. I bought it but was inconsistently taking it. We went to Hawaii and I packed all my supplements and was diligent until the last day or two. My period was 10 days late. No pregnancy. July comes, and I’m taking my supplements (CLA included) again. (My supplements are multi, biotin, magCitrate, and VitaD.) I “spot” about 4 days before my period should start but only enough to basically wipe. This month, I started getting my water in properly (1/2-1 gal per day) and have paid more attention to my diet, but nothing horribly drastic. Monday, I have same type of spotting–just in wiping–and it’s gone. Period isn’t due until the 31st. My skin is broken out, and I’ve always been 28 days to the letter before I started consistently taking CLA.


hi amanda, Istarted taking the cla pills on the beginning of this month ( october) i was suppose to get my period the 12 of this month and as of right now I am 7 days late. I just want to know how everything turned out with you? how long did it take for your period to show? I am very concerned, scared at this point. I am always on schedule for my period date.

Victoria (Editor)

Hi Amanda. Please make sure to consult with your physician before continuing to take this product and let them know about the side effects you were experiencing.

Victoria (Editor)

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


Have been taking CLA for about 4 mos now and it seems that my blood pressure is extremely high. I follow a healthy diet, no processed sugar, very little carbs, walk at lest 2 miles a day. Anyone else experiencing high blood pressure?

Victoria (Editor)

Hello. All users are different and can experience different side effects, but we have noticed that users have experienced somewhat similar side effects. Please make sure to consult with your physician before continuing taking this product if you are still having side effects.


I apparently am allergic to it. Except for a mild headache and slight heartburn and gastro distress in the first few days, things were good. My appetite was lower and I was able to increase my exercise. But after a week, I started experiencing shortness of breath and I broke out in hives. Stopped taking it immediately and took a Zyrtec for the hives which seem to be subsiding.


I have been taking tonalin cla 1000mg for a week now. I got it to help ton up my body because I am also taking super citrimax and waterex with it for weight loss. Since taking do have just a little more accnie on my chin but just really tiny spots hear and there. So far no bad side effects but I haven’t been taking it long enough to see results of skin tightening. All tho I do not use a scale with what I have been taking I can now ware pants I couldn’t two weeks ago!!!


I have been taking CLA for about a week (3 a day of 1,000 mg). I can tell you that I slept through the entire weekend. I mean I could not keep my eyes open. I would get out of bed to use the restroom, stumble to the couch, and then pass out. I saw that fatigue is a side effect for some. I workout 6 days a week doing a combination of weight lifting and cardio. I count macros and live a generally healthy lifestyle. Has anyone else experienced this side effect? I am going to finish the bottle which is a 30 day supply. I am just glad I didn’t let the sales associate talk me into the bottle that had 120 2,000 mg tablets.


I think is it great, curbs my eating for sure.. as soon as I take it … I do same workout regime as you and am very healthy – no junk, no processed foods.. May be try SOLGAR brand they are my got to best vitamin brand … more expensive but really great quality I am on 1300MG CLA and will continue to take… no side effects at all… happy happy

  stomach cramps or twisting
Mizz Lee (Verified User)

Has anyone experienced chronic gas and bloating while taking Tonalin. That sometimes feel like stomach cramps or twisting?


I have IBS & have found that taking CLA after eating reduces my gas & seems to help my digestion. I have not noticed feeling tired or any negative reactions. I don’t take it after every meal generally, but do take it after dinner.


Yes I have experienced the same thing also no weight lose


Yes I have a lot of gas since taking Tonalin CLA.and most recently my eyesight has changed especially when reading my eyes feel like their burning I have never experienced this before using the tonalin


yes. I thought it was the chicken I had for dinner. But then took CLA again the next 2 nights with different foods and same issue. Pain started right under left rib cage. Was like a big hard knot. Then felt like my intestines on the left side were twisted.

Stephen (Editor)

Looks like you’re having an odd reaction. Anyone else experience this?

La Vonne

I have been on Tonalin CLA 1250mg for several weeks now. While I have noticed a 4 pound drop, I have experienced severe bloating, gas, and my back and skin have become so very very itchy. Seriously I look 5 months pregnant. I have also noticed shortness of breath which I attribute to the extreme and uncomfortable bloating. I am stopping today since I read that for some it has increased their BP and I already have hypertension. I am also quitting because weight loss of 4 pounds in 6 weeks is not a fair trade to now look like a pregnant woman at the age of 60.

   I would not recommend this product
Molly (Verified User)

I’ve been taking Tonalin CLA for 3 weeks now and have gained weight and feel horrible (probably because of the weight gain). It’s very disappointing because I lost weight while taking Citrimax but had to stop because it eventually caused major intestinal problems. The Health/Vitamin store recommended Tonalin CLA but it certainly doesn’t work for me. I would not recommend this product for weight loss.


I noticed that I’ve gain weight as well. Also, my poop is black. Has anyone else noticed this?

  Have some SIde Effects

Could I be allergic to something in Tonalin CLA? I have only taken it 2 times in one day and both times my throat felt like it was swelling up. I also have a headache which rarely happens to me.

Cameron (Editor)

If your throat swells and restricts your breathing it is possible you are allergic. Please review the ingredients list with your doctor for information on alternatives and risks.

  did NOT have side effects
Peggy Keeler (Verified User)

This is the only diet supplement that I have ever used that did NOT have side effects. I have lost 50 pounds without exercising or dieting. I try to never eat sugar and to eat low fat meats. I have not eaten pork in years but I do eat 90% fat free beef, chicken, and turkey. Since last spring I have lost 45 pounds. At first it was a pound a week but it slowed down in the last few months to about a pound a month. I have never had such good results and I feel great..

  No So Much Changed
Raquel (Verified User)

HI all:
I’ve been taking this Body Toner Censor (tonalin) sold by GNC, I cut all of the carbs in my diet, (which I love) I take two of these capsules with meals and plenty of water, walk 9 miles everyday after work and during work I’m constantly moving, I have not lost any weight, however, I do see that some of my tighter fitting clothes are starting to fit, the scales that I go on all read the same, same weight, I’m not eating candies, no breads, no pastas, just a big salad at home with fresh veggies, I grill every night 3 oz of lean meat or chicken or fish and no weight loss, the pain that I’m experiencing I was attributing to the walking it is on my hips so other than that I don’t know what else to add, I will continue for another month, if I don’t see a weight loss then is off to find another product as exercise is not helping it either, odd.


You are already too thin . Change your mirror


Dont use scales they don’t help anything. If you are gonna use a scale make sure you weigh yourself at the same time everyday

Drink more V8 or drink carrot juice to improve your eye sight.

  drinking a TON of water

Does anyone notice a change in their urine color- Dark Yellow and I am drinking a TON of water…normal?


Drink 5 bottles of water to keep going to the bathroom to urine and clear it.


Can this product cause a rash? It’s the only change, besides reduce caloric intake. Thanks.


I have read that it does indeed (or it can) activate allergies. I startedtaking it with an open mind and unfortunately also had an allergic reaction. I’m a bit stubborn so I am taking something else to control the allergy (which is really no longer a problem) and I am still taking the tonalin…

  This always worked for me

Hi. I am a 54 year old man ( just turned 54 in August). My height is 6′ 2 1/2″.

To start with, I am not recommending any supplement! I only want to tell you my story. The best advice I can give is to always check with your doctor before taking ANY supplements.

My Story:

Last December I was diagnosed with with adult onset diabetes. My triglycerides were 454. HDL was 30 A1c was 7.5. Had a 44″ wait and weight 238 pounds. . My BMI was at 29.2. I also have IBS
I was put on cholesterol, IBS and diabetes medicines and told to lose weight.

I started a diet of cutting out all bad carbs (white bread, white potatoes, sweet tea, and candy). I also increase my fiber intake. I dropped my calorie intake to approximately 1600 cals per day. Did not do any exercise because I have a desk job and work about 14 hours a day.

I was surprised to see my weight start dropping immediately. The supplements I took were a multivitamin a day, fish oil (i know there are mixed reviews on this but my doctor said he trusts it for lowering triglycerides).

By February I was down to 210 pounds. Then plateaued.

I was happy I had lost 28 pounds and figured that was all I was going to lose, but with the change in my diet I had actually already changed my eating habits and liked the new diet so decided to just keep eating exactly like I had become accustomed to. Did not change anything else.
In March my weight started dropping again. remember I had not done anything new, just ate the right way now.

In June I went back to my doctor for a check on my diabetes. My Doctor was amazed. I was now at 178 lbs, my A1C was at 5.3, my HDL was at 45, and triglycerides was at 114. He took me off all my meds. BTW, I no longer had any of my IBS symptoms. My doctor told me he was very happy, but wanted me to stop losing weight as my BMI was at 21. He also took me off all my meds (IBS, Cholesterol, Diabetes) and told me to come back in 3 months to see if I would need to be put back on them.

Even though I had lost 60 lbs in 6 months, and my waist had dropped to 36″, I really wanted to take it to the next level and aim for a 34″. I started taking AbsCut CLA, after doing research on the web about CLA.
I started taking 3 pills a day to see if it worked and determine any side effects it might have, I did ask the doctor if he thought it would be safe and he said it would be okay. After 2 weeks with no side effects I upped the dosage to 7 pills a day for a total of 3.5grams a day. I took 2 with my breakfast, 2 with lunch and 3 with supper.

I increased my calorie intake to 2000 cals per day to keep from continuing to lose weight, including the “occasional” french fries and mash potatoes (once or twice a week) . I also started doing 15 minutes of treadmill 3 times per week. Actually the only exercise I had done in 10 years. (haha)
It is now Sep and I jst got back my three month review from the doctor.

First, my waistline is now 33″. I still weight 178 lbs, and my A1C is still 5.3, my HDL is still 45, my triglycerides are at 95, and my doctor said I could stay off the meds and continue to increase my exercise and keep eating right. All my other test (liver, kidneys, prostate, and blood) are all normal.

I am actually starting to try bodybuilding now (I know, I am 54, but want to prove an old man can still get ripped ads and build big arms). I asked my doctor about several other supplements I wanted to take in this new adventure (P6 Extreme, and C4 Carotene) he approved both of them for me. He actually took the time to read the containers I took in to him. BTW I love my doctor, takes the time to really understand what I am trying to do and reads all the container information and explains what each ingredients means and how they affect my body and what to expect.

I know supplements work in different ways for different people. AbsCut seems to have worked for me in reducing my waistline when I increased my calorie intake. I did not lose any weight while on it, but did reduce my waistline.

Again, BOTTOM LINE, it worked for me , but ask your doctor before taking any supplements. That way you are not guessing but actually know if the supplement will affect you body based on your medical history.

Hope this helped and best of luck to all you you in your endeavor.

We haven’t heard it either, Gloria. Consult your doctor and in the mean time take a break from Tonalin CLA.
