Sustamine®, an ingredient also known as L-Alanyl-L-Glutamine, is a stable compound made up of the amino acids L-alanine and L-glutamine. It is more easily absorbed by the body than other forms of glutamine. Some studies have shown that Sustamine® may be highly effective for hydration, endurance, and recovery. It may be a suitable alternative to oral glutamine due to its ability to better survive the acidic environment of the gut. Sustamine® virtually disappears when it is added to a clear glass of water leaving no residue at the bottom of the glass.
