L-Cystine is the stable, oxidized form of L-Cysteine. Cystine is known as a disulfide amino acid because it consists of two Cysteine segments with their respective sulfur atoms bonded firmly together. The body can convert L-Cysteine to L-Cystine and vice versa, however L-Cysteine is the more bio-active of the two. L-Cystine has a bland taste and can be taken in powder or capsule form. The powder is water soluble and weighs about 4.6 grams per level measuring teaspoon. An adequate supply of Vitamin C and B6 should always accompany any Cysteine or Cystine supplementation.
