Gluten FreeAmino Acid for Optimal Arterial HealthDietary SupplementNon-GMO LE Certified The human body naturally produces L-arginine. It is also obtained through diet. But some people struggle to get enough of this semi-essential amino acid through either of those routes. Our L-Arginine Caps provide 700 mg of L-arginine along with 6 mg of vitamin C to support arterial health and more.This semi-essential amino acid is involved in numerous areas of human biochemistry that contribute to overall health.L-Arginine Caps Benefits Supports arterial health Helps maintain healthy tissue & bones Supports already-healthy blood pressure levels May help maintain a healthy immune systemL-arginine is a semi-essential amino acid involved in numerous areas of human biochemistry that contribute to overall health. It modulates immune function, detoxifies ammonia for removal from the body and serves as a precursor for nitric oxide.Nitric oxide is a potent vasodilator, and supplemental L-arginine can therefore support already-healthy blood pressure levels. Higher intake of arginine is also linked to lower levels of C-reactive protein, an important marker of a healthy inflammatory response to support cardiovascular health. L-arginine may also help maintain the health of the immune system.

It is also an important fuel for immune cells that promote optimal immune function.What Is L-Glutamine?Glutamine supplements are often associated with serious athletes, but it can be beneficial for anyone who wants to not only maintain muscle health, but also immune and gut health.Glutamine is the most abundant free amino acid found in the body.L-Glutamine BenefitsSupports healthy muscle massHelps maintain energy levels under heavy stressHelps maintain optimal immune function & gut healthGlutamine can be found circulating in the blood, as well as stored in the skeletal muscles and liver, in concentrations ranging from 10- to 100-fold higher than any other amino acid.Glutamine is utilized in a number of vital functions, including protein synthesis and production of the nucleotide units that make up DNA and RNA. Because of its importance in many cellular functions, glutamine is consumed at especially high rates during activities involving intense exercise. It is an important energy source for cells lining the gut and immune cells and critical for healthy gut and immune function. It is also a precursor of the brain neurotransmitter glutamate.The function of glutamine in stimulating glycogen synthase, the enzyme that controls the synthesis and storage of glycogen fuel in muscles and liver, may provide a mechanism by which glutamine supplements promote enhanced fuel stores.People who engage in heavy exercise can affect their glutamine levels, causing stress to their body and immune systems. Supplementing with glutamine can be important to a serious athlete, someone challenged with muscle loss or someone who wants to help maintain optimal immune function and energy level under heavy stress.Studies indicate supplementing with glutamine can effectively raise glutamine concentrations in circulation and in muscle tissue, promote a healthy inflammatory response and support antioxidant defenses to maintain muscle health.
