116 Servings. Glutamine is the most abundant amino acid in the body and plays an important role in the muscle protein development. During prolonged periods of intense exercise glutamine levels can be depleted which may limit protein synthesis. Our Glutamine Powder is a simple way to supplement your diet with this amino acid. Just one teaspoon of Glutamine Powder provides more glutamine than 4 jumbo eggs, 4 oz. of lean beef, 3/4 cup of soybeans, or a 4 oz. chicken breast. Because it's unflavored and instantized for easy mixing, you can add the powder into fruit juice, protein shakes or your favorite weight gain formula.
