1. NAC + Glycine powder is a powerful combination that provides a wide range of health benefits. NAC, or N-acetyl cysteine, is an antioxidant that helps support the body's natural detoxification process and promotes healthy lung function.
2. Glycine is an amino acid that helps support healthy nervous system function and improves sleep quality. Together, these two ingredients work synergistically to promote overall health and well-being.

The Active Ingredient Is: N-acetyl-L-cysteine (NAC)

N-acetyl-L-cysteine, a derivative of the amino acid cysteine, is named here as the active ingredient. NAC and glycine are recognised as building blocks for glutathione production, supporting the body's master antioxidant system. This formula also includes glycine, which aids support for the same antioxidant pathway.

This ingredient is commonly sourced as a cleaned amino-acid derivative and is used to support antioxidant equilibrium through its part in glutathione production. The formulation emphasises a hypoallergenic approach, focusing on high-quality amino acid precursors to support the intended antioxidant function.

What Does N-acetyl-L-cysteine (NAC) Do?

N-acetyl-L-cysteine helps support glutathione production, a key cellular antioxidant that contributes to normal oxidative balance within the body. This mechanism aligns with broad scientific understanding of NAC as a cysteine supplier used in antioxidant pathways, with glycine also present to support this role.

In line with EFSA and NHS guidance on antioxidants, the blend of NAC and glycine in this product supports the normal function of the body's antioxidant system through glutathione production.
