Lab animals fed CLA-rich butterfat have stronger bones

Animal studies suggest that CLA enhances bone formation. Chicks and rats fed CLA-rich butterfat had greater bone growth than animals fed other fats. Researchers attribute the stronger bones to CLA's ability to block excess production of an inflammatory substance called PGE2. Grassfed dairy meat and dairy products have from 2-5 times more CLA than ordinary products.
