Gluten FreeAmino Acid for Optimal Arterial HealthDietary SupplementNon-GMO LE Certified & nbsp;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 & nbsp;Supports arterial health & nbsp;Helps maintain healthy tissue & amp; bones & nbsp;Supports already-healthy blood pressure levels & nbsp;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 & amp; 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.

Berry Flavored Amino AcidsDietary SupplementKIONMuscle/TendonMetabolismFoundationalNSF - Certified SportGluten FreeOptimize your workout results and build the lean muscle mass that boosts strength. The Amino Complex formula also enhances cellular energy production.Amino acids are the building blocks of protein. They fuel muscle gain and other physiological functions, including enzyme production, hormone regulation, cognitive ability, neurotransmitter balance, metabolism, and energy production.. As we age, we lose muscle mass, which can cause other health issues, so it is important to promote the growth of lean muscle mass.Of the 20 amino acids in total, nine are classified as essential amino acids (EAAs), those the body cannot produce itself. Therefore, they must be consumed through diet and supplementation to support the body’s internal production of energy.Thorne’s Amino Complex is a comprehensive blend of essential amino acids, which is high in branched-chain amino acids (BCAAs) – a group of amino acids validated through clinical trials to promote the growth of lean muscle mass and enhance muscle strength.EAAs benefit the body in multiple ways:Support muscle repair and recovery & nbsp;Reduce muscle soreness & nbsp;Increase energy production & nbsp;Promote healthy blood sugar & nbsp;Support cardiovascular health & nbsp;Strengthen connective tissueAmino Complex’s formula supports sports, fitness, and training-related activities.. Additionally, it promotes the growth of muscle mass in individuals who need to preserve muscle mass, including the elderly.Amino Complex comes in two flavors – lemon and berry – and is lightly sweetened. It mixes easily with warm or cold liquids, and contains flavors and sweeteners derived from natural sources.It is best taken after a workout to facilitate the recovery process. It’s an ideal formula for active individuals, individuals managing calories, or anyone who has difficulty consuming whole foods or protein powders, particularly after heavy exercise.Because athletes need to know their supplements are trustworthy and compliant, every batch of an NSF Certified for Sport® product is tested for compliance with label claims and to ensure the absence of more than 200 substances banned by many major athletic organizations.

Taurine, 90 Capsules
Dietary Supplement Foundational Heart/Vessels Liver/Detox Gluten FreeTaurine is a conditionally essential, sulfur-containing amino acid found in the tissues of most animal species. It is not incorporated into proteins, but is found free in many tissues. Taurine is involved in a number of physiological processes, including bile acid formation for fat digestion, fluid regulation, detoxification of environmental toxins, regulation of cellular calcium, and regulation of nerve excitability. The liver combines bile acids with taurine, which results in increased cholesterol solubility and excretion. Individuals who are taurine deficient may be more susceptible to tissue damage from environmental pollutants such as aldehydes, chlorine, and amines.Taurine is the most abundant amino acid in the heart. Taurine has been shown to improve nitric oxide production in the vascular endothelium, which is essential to optimal blood flow, maintaining already normal blood pressure, and overall cardiovascular functioning. Taurine acts as an antioxidant as well, inhibiting LDL cholesterol oxidation.
