Cysteine: essential nutrient for Glutathione synthesis, useful for hair, skin and nail health, supports healthy joint function, protects the stomach and intestines from damage caused by aspirin and similar drugs - Free of all common allergens - Non-essential amino acid

Cysteine is a sulfur containing non-essential amino acid that is closely related to cystine. Cystine actually contains two cysteine molecules that are joined together. Being a non-essential amino acid means that sufficient amounts of Cysteine are formed from L-Methionine (an essential amino acid) and L-Serine via a transsulfuration reaction in the body. However, for preterm infants Cysteine is considered to be a conditionally essential amino acid. L-Cysteine serves as a precursor for the synthesis of proteins, glutathionine, taurine, coenzyme A, biotin and inorganic sulfate, and also serves as a major precursor for the synthesis of the potent antioxidant glutathione. Without adequate amounts of glutathione in the liver, the tissues of the body can be exposed to significant oxidative stress resulting in widespread cellular damage.

Our L-Cysteine is available in 500 mg capsules in a 100 count bottle.

Research Indicates

• Essential nutrient for Glutathione synthesis
• May have positive effect on the inflammation response
• May have mild detoxification effects
• May support healthy joint function
• Due to sulfur content, may be useful for hair, skin and nail health
• May be helpful for protecting the stomach and intestines from damage caused by aspirin and similar drugs

Suggested use: typical daily dosage ranges from 500 to 1500 mgs.

Cautions

• If you are pregnant or lactating consult your health care practitioner prior to using L-Cysteine.
• There have been rare reports of renal stones (cystine stones) associated with excessive Cysteine intake. Drinking water and supplementing with Vitamin C has been shown to prevent cystine stones.
