1 Animal studies have found that CLA can inhibit malignant melanoma, colorectal, breast, ovarian and lung cancers in experimental animals. In animal studies, CLA reduced the risk of heart disease. In these models, LDL cholesterol and triglycerides dropped among CLA-fed subjects. 7 CLA also appears to influence body fat levels. Several animal studies have noted that CLA induces a decrease in body fat and an increase in lean muscle.
Trials are currently underway to confirm benefits for humans.
8,9,10,11 CLA was found to prevent diabetes in animal models.
