Product Benefits

Taurine is an amino acid which occurs naturally in the body. From an athletic standpoint, taurine has been shown to have several health benefits, including those related to endurance and vascular function.

L-citrulline, an amino acid produced in the body, is converted by the kidneys into another amino acid, l-arginine, a precursor to nitric oxide. Nitric oxide is a vasodilator, meaning it expands the arteries to allow greater blood flow during exercise. Vasodilation also helps to lower blood pressure, so citruline has been used in the treatment of hypertension.

Carnitine is an amino acid which plays a key role in energy production, and has been shown to facilitate the transport of long chain fatty acids into the mitochondrial matrix, triggering cardioprotective benefits through reduced oxidative stress and inflammation. Studies on carnitine have highlighted its effectiveness in the treatment of chronic heart failure, arrhythmia, peripheral vascular disease, and acute ischemia.

N-acetyl-l-cysteine, or NAC, performs a number of benefits. Together with glycine and glutamine, NAC produces glutathione, a powerful antioxidant; it also helps maintain healthy liver function and healthy lung function.

N-acetylcysteine ​​and carnitine can cross the blood-brain barrier due to their antioxidant properties, and thus help maintain the health of blood vessels and nerve cells. These antioxidants also have beneficial effects on mitochondrial and circulatory functions, methylation, and homocysteine ​​metabolism.

Inositol is a carbohydrate found naturally in the body. Inositol helps to keep anxiety in the normal range and plays a role in the processing of serotonin, an important neurotransmitter in the brain often associated with feelings of well-being and happiness.

Magnesium has many benefits, from healthy bone formation to cardiovascular health to healthy muscle maintenance. Pantothenic acid is included for additional benefits.
