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.
What Users Are Saying
“Since I have started taking this product I haven’t had as hard a challenge to reduce my weight!”
“Hmm, didn’t seem to do much for me. I also started exercising and eating healthy, and lost 5 lbs in 4 weeks. So I’m not certain that had much to do with the capsules. At least they didn’t give me heartburn.”
“Did not notice anything.”
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 this year is our supplement called Burn HD. 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 2-Week Sample, which is a great sign.Learn More About Burn HD »
