SuperG is an advanced nutritional supplement that can help you preserve your muscle. L-glutamine is a conditionally essential Amino Acid, which means that the body can run low on supply. 80% of the body's L-Glutamine is sourced from the amino acids from muscle tissue. Immune Spring, LLC was founded on the theory that supplenting with L-Glutamine prevents muscle breakdown to produce L-Glutamine for the rest of the body. This theory has not been endorsed by the FDA. SuperG is far better than normal L-Glutamine: 1) Get into solution twice as fast, 2) Has Vitamin C and Zinc to improve your immune health 3) Tastes Great, light lemon and slightly sweet 4) A pleasure to take every day. One scoop into a glass or bottle of water, stir or shake and you've got the best nutrition possible!
