Interestingly grass fed meat and dairy have been found to have higher levels of CLA. It is not produced in the body but has many benefits. Many people are taking CLA supplements to help lose fat and retain lean muscle mass. It was first discover in the 1970’s and became the subject of more research when in 1987 a study on mice found it to inhibit cancer growth and was recognized by the FDA as a GRAS (Generally Recognized As Safe) supplement in 2008.

Okay, What Does It Do?
Fortunately for us CLA has been the subject of quite a bit of research. Some has been inconclusive but there are a lot studies that have shown CLA to have a positive effect on weight loss, retention and building lean muscle mass, cancer, heart disease, and diabetes.

CLA is not known to have interactions with other drugs. As with many supplements people first taking CLA have reported some side effects like nausea or stomach upset. I’ve had no problem. WebMD advises stopping CLA two weeks before surgery, they make that recommendation for most supplements.
As with any supplement more is not necessarily better. Never take more than the recommended dosage and it’s always a good idea to check with your doctor before starting any new supplement. Buy your supplements from a reputable source and make sure they’re manufactured in the USA.
