Started using a teaspoon daily of Colustrum in my shakes/drinks.
Not sure if it will do anything, but most studies seem promising. Plus its cheap (Now brand, 70 servings for like 10 bucks).
Although there are a relatively few number of research studies performed on bovine colostrum all of them show empirical evidence of aiding athletic performance. It appears that strength and muscle mass increases are the most evident results of bovine colostrum supplementation. Some of the other noted benefits associated with bovine colostrum supplementation include: increased IGF-1 levels, increased hormone levels, increased peak anaerobic power and vertical jump, reduced endurance times, and enhanced ventilatory system and cardiopulmonary processes by helping individuals work more efficiently. It should be noted that bovine colostrum's powerful effect on increasing IGF-1 levels is so prominent that the NCAA has banned its supplementation for its athletes. Therefore collegiate athletes should avoid using this product. However, professional athletes may find it highly advantageous to their performance.
