L-Cysteine can be obtained from dietary protein or synthesized from the amino acid L-methionine. It is directly depleted by cigarette smoking, the depletion of which may be partially related to the faster aging of skin in smokers.*

L-Cysteine is a sulfur containing amino acid which, together with glycine & glutamic acid, forms the all-important antioxidant glutathione. L-Cysteine contributes to the formation of protein in our bodies. It plays a role in energy metabolism, both by being able to convert to glucose & be used as fuel, & by playing a part in the synthesis of fatty acids. It acts in the liver to help detoxify carcinogens & other dangerous chemicals. Cysteine is essential for T-cell proliferation & activation in your immune system. Cysteine is a major component of skin, hair, & fingernails. Studies show that cysteine supplementation can increase hair shaft diameter and hair growth density in some cases of hair loss.*

  • Help with skin health.*
  • Stop hair loss & aid normal hair growth.*
  • Support the liver.*
  • Helps the body's natural detoxification process*
