Optimistic On Ursolic Acid

A few months ago, the first human studies were completed on ursolic acid, a natural substance found in rosemary and apple peels that has shown promise for boosting health and improving body composition in animals. Scientists in Korea gave subjects experienced in weight training 450 milligrams of ursolic acid a day for eight weeks. The researchers were expecting to see a dramatic uptick in muscle mass; while subjects did gain some muscle mass, the scientists were surprised to find that the most dramatic effect was on fat loss as well as strength. Scientists hypothesized that ursolic acid supplementation boosted the concentration of IGF-1 and irisin, a protein that muscle cells secrete when they are active.
