What are some reccommended anti-catabolic supplements? I was taking glutamine for awhile but I would constantly have acne breakouts. I eat fare amount of eggs and other anti-cataboic foods in my diet just feel that since I run a lot that I may need a type of supplement. I realize doing long distance running can burn muscle tissue but what about sprints? I was thinking about dropping my long distance runs to high intensity sprints instead. I'm mainly just trying to lean out and keep as much muscle as possible.
