You train hard -- really hard. The last thing you need is unintentional down time to counteract your efforts. Hedge your bets with glutamine. This conditionally essential amino acid accounts for about 50% of your total amino pool, making it the most abundant amino acid in the body. So, you should keep your supply well-stocked -- especially during the winter months and at times when you're pushing yourself to the limit. Gluta-Force combines pure L-glutamine and bonded glutamine peptides for effectiveness at an affordable price.
