Doctor’s Best L-Glutamine Powder supplies a high level of the amino acid glutamine, a building block of protein, and essential support for all things muscle – it’s growth, mass, strength, recovery, hydration and endurance. It is also plays an important role in energy production, as the major fuel source for the liver, intestines and immune system.
L-Glutamine is the most abundant free amino acid in the body. It is mainly made in the muscles, liver and lungs, but when the body is sick, injured, under stress or subject to intense physical demands our need for this critical amino acid exceeds our capacity to produce it in necessary amounts. As a building block of protein, L-Glutamine plays a significant role in muscle growth, development, strength and recovery, and it also plays a vital role in energy production as the major fuel source for the liver, intestines and immune system.
L-Glutamine has become widely known and used for its ergogenic capabilities, improving physical performance, stamina and recovery after intense exercise among athletes. It is also very popular for its role in immune health and exercise. It is also converted in the body to glutamic acid, a precursor to the neurotransmitter GABA.

Doctor’s Best is committed to transparency and education and uses only certified cGMP facilities to ensure the highest quality standards are met.
