Ready to be absorbed

Lamberts® L-Cysteine is a pure, free-form amino acid that is ready to be absorbed by the body without needing to be broken down by digestive enzymes. Each capsule provides a full 500mg of L-Cysteine and is made in the UK to pharmaceutical GMP standards.

Cysteine is an important source of dietary sulphur and many of its important roles in the body involve the thiol (sulphur) group attached to each molecule of the amino acid. Sulphur is essential in the diet and obtained principally from the intake of proteins rich in cysteine and methionine. The other sulphur containing amino acids, taurine and cystine are synthesised from cysteine.
