CLA, or conjugated linoleic acid, is a polyunsaturated fatty acid that naturally occurs in various animal products such as meat and dairy. It offers several potential health benefits for humans, including the reduction of body fat, improved insulin sensitivity, and anti-inflammatory effects. Extensively researched for its impact on weight loss and muscle growth, CLA also shows potential in preventing chronic diseases like heart disease and cancer. Additionally, it is available as a dietary supplement in capsule form.
