During prolonged periods of intense exercise, glutamine levels may be depleted faster than the body can replenish them, which limits protein synthesis and can even encourage muscle breakdown. Our Glutamine 1000 Caps are formulated for rapid disintegration and provide 1,000 mg of pure L-Glutamine per capsule so they deliver a quick, powerful dose each and every time.
