The dietary supplement Zoomad Labs One Unflavored contains glutamine, a semi-essential amino acid that helps support the immune system, as well as brain and digestive health. Glutamine plays an important role in providing vital “fuel” to the body’s cells and is crucial for the production of glucose and other amino acids, which are fundamental components of proteins. This formula is ideal for those who wish to support their overall well-being and is flavor-free, making it easy to add to your diet.
