Name: CLA (Conjugated linoleic acids)

Purpose: Anti-cancer causing properties and assists with lean muscle mass growth and body fat reduction. CLA could also have anti-inflammatory properties.

Price Range: $50 -$100 per bottle. (Usually 90 caps)

Ingredients:  Conjugated Linoleic Acid is made of more than 28 Isomers of Linoleic Acid. Linoleic Acid is an Omega -6, Poly unsaturated Essential Fatty Acid most commonly found in meats and dairy products and some rare mushrooms in smaller amounts . The body cannot synthesise Linoleic acid from other foods. Most supplements on the market have converted the linoleic acid from safflower or sunflower oil sources.

What it apparently does and how it allegedly works:

Several studies conducted both on animals and humans have found that supplementing with between 3-4 grams per day of CLA can assist with the reduction of body fat and growth of lean muscle mass.

When leading CLA researcher Michael W. Pariza from the University of Wisconsin-Madison was asked, “How does CLA work?” he replied, “In a general sense, what it’s doing is keeping little fat cells from getting big… perhaps by blocking certain enzymes that let fat cells swell.” (

Things to remember:

There is a belief that extremely obese people should not supplement with CLA as it may promote and or cause insulin resistance which can then lead to diabetes. It is also important to remember that CLA has only been researched for around 40 years but at this stage it does appear to be relatively safe for human consumption.

Commercially available supplements contain mixtures of two CLA isomers: the cis-9, trans-11 isomer (also known as rumenic acid, the predominant CLA isomer in milk and beef), as well as the trans-10, cis-12 (t10c12) isomer. The trans-10, cis-12 isomer is linked to many adverse side effects.
