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.
What is Tonalin CLA?
First off, Tonalin CLA is a fat burner.  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  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 ,” 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 ,” 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. 
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. 
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.  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  and not proving the immune system in healthy individuals would improve.  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 in 2016 is one called Leptigen. It blends four clinically-tested ingredients that have been shown to help accelerate fat loss and boost metabolism. No one’s talking about harmful side effects and reviews show people are seeing excellent results.
The makers of Leptigen are offering a Special Trial Offer; an exceptional sign of confidence in their supplement.

We dug deep into the Tonalin CLA ingredients to give you the details you need.
Also known as Conjugated Lineolic Acid, 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.
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.
