When it comes to weight loss, the dieter has more than a thousand choices for a weight loss supplement. One of the biggest disappointments in the weight loss industry is CLA. CLA stands for conjugated linoleic acid and while there are clinical studies proving the ingredient supports lean muscle growth and fat loss, the results are based in a population of people who are fit and trim. Dieters falling into the overweight and obese categories will not see the benefits claimed in CLA product descriptions. Most CLA products contain conjugated linoleic acid derived from safflower oil. ProLab CLA chooses a Tonalin blend. Tonalin is the brand name for the most famous CLA supplement.

List of Ingredients

Tonalin Proprietary Blend: Conjugated Linoleic Acid, Oleic Acid, Palmitic Acid, Stearic Acid and Linoleic Acid.

Product Features

The proprietary blend makes ProLab CLA unique, but the additional ingredients offer no additional weight loss support. ProLab CLA contains 1,200 mg (proprietary). Of that 1,200 mg, we assume about 1,000 are from conjugated linoleic acid as this is the average amount in CLA supplements. The product description states the supplement helps improve muscle tone and utilization of nutrients.

Clinical studies performed with CLA prove the supplement does affect weight and muscle tone. Dieters can take the supplement, but without an active exercise program with weight training, the supplement is unlikely to promote lean muscle mass. Muscle does not build itself. In order for muscle to grow, the dieter must train with weights, tear the muscle and allow the muscle to heal. Muscle “scars” are new muscle.

Conjugated linoleic acid comes with the risk of gastrointestinal side effects. Dieters may experience bloating and cramping while taking the supplement. The symptoms should last only a short while. Taking more CLA does not improve how the supplement works. More CLA can actually increase the risk of side effects.

There is very little benefit of taking a CLA supplement for the average dieter. ProLab CLA may help a fitness buff or bodybuilder lean up, but it will not help the average dieter shed 40 pounds. There are tons of CLA supplements and all contain the same base ingredient; CLA from safflower oil. Every supplement offers the same product description and same weight loss claims, but testimonials do not support these claims. No matter how many clinical trials are performed, if the average dieter does not lose weight taking a supplement – it does not work.
