Now Foods L-Cysteine 500 mg Nutritional Supplement for Hair, Skin & Nails, 100 tabs

L-cysteine is an important component of hair, nails and skin. It stabilizes the structure of proteins and helps in the formation of collagen.

L-cysteine performs several functions in the body. It is used to make taurine and glutathione. Taurine plays an important role in the functioning of the nervous system and helps regulate blood pressure, maintain good vision, while enhancing thermogenesis and muscle building. Glutathione is crucial for the functioning of the immune system, as it is a powerful antioxidant that ensures healthy cellular function. L-cysteine supplementation increases NAC levels. NAC is known to increase glutathione levels in the blood and help maintain muscle mass.

L-cysteine can also be converted to glucose when blood glucose levels are low. This conversion can enhance the endurance of athletes. Physical exercise is known to increase oxidative stress and this can lead to immunosuppression. L-cysteine can help speed recovery.

NOW L-cysteine supplements may be most effective when used in combination with vitamin E, vitamin C, vitamin B6, calcium, and selenium.
