What is N Acetyl L Cysteine?

N-Acetyl L-Cysteine (NAC) is the n-acetyl derivative of the amino acid L-cysteine, and is a precursor in the formation of the antioxidant glutathione in the body.

Glutathione is one of the body’s most important antioxidants, which helps neutralize free radicals that can damage cells and tissues in your body. It’s essential for immune health and fighting cellular damage.

Some researchers believe it may even contribute to longevity.

Foods which contain L-Cysteine include as chicken, turkey, cheese, eggs and yogurt.

Our N Acetyl L Cysteine powder has been manufactured through a fermentation process, using corn as a starting material, our NAC powder is suitable for vegetarians and vegan.
