Tonalin Reviewed
Tonalin is simply a brand name for conjugated linoleic acid (CLA)—a weight-loss ingredient that has shown mixed results in clinical studies.
The health experts at DietResearch.com do not necessarily recommend against products containing CLA, but we do recommend products that contain more than just CLA.
With something as simple as Tonalin supplements, you won’t get a lot of bang for your buck.

Safety and Quality
Tonalin is a brand name version of conjugated linoleic acid (CLA). When CLA occurs naturally in meat and dairy, it inhibits enzymes that breaks down fat in the body. Some clinical studies have shown CLA to promote weight-loss in obese and overweight animals and humans.
However, other studies—including one published in the Journal of Lipid Studies in 2003—have shown the weight-loss effects to be minimal compared to the risks. Chemical CLA has been linked to liver damage and an increased likelihood of diabetes.
“Although CLA appears to attenuate increases in body weight and body fat in several animal models, CLA isomers sold as dietary supplements are not effective as weight loss agents in humans and may actually have adverse effects on human health,” reads the study.
Effectiveness
The effectiveness of CLA is debated among medical professionals, and the experts at DietResearch.com believe that even if CLA works, one ingredient is not enough for a diet supplement. The supplements on our list of best diet pills have complete and effective weight-loss formulas.
Cost
A one-month supply will cost $15 to $20. This is a good price for a natural supplement, but too much for one ingredient—especially one as controversial as CLA.
Customer Service
Cognis Group makes Tonalin, but they have no rating with the Better Business Bureau.
Money-back guarantee
Tonalin is not backed with any guarantee.
