Solgar® NAC 600 mg provides N-Acetyl-L-Cysteine, a stable form of the amino acid L-Cysteine. Amino acids are the building blocks of protein and are found naturally in foods such as meat, dairy, and beans. L-Cysteine is a sulphur-bearing amino acid that takes part in natural metabolic processes in the body. It is involved in the synthesis of keratin — the protein that forms hair, skin, and nails — and can also be used by the body to make glutathione. Each vegetable capsule provides 600 mg of NAC and is suitable for vegan, vegetarian, and kosher diets. This simple, one-a-day formula is free from sugar, salt, and starch.
