The Active Ingredient Is: L-Cysteine

L-Cysteine is basically a non-essential amino acid that acts as a building block for proteins and as a precursor to the antioxidant glutathione.

This formula uses L-Cysteine in a vegetarian-friendly tablet and includes vitamin C to boost absorption and activity.

What Does L-Cysteine Do?

L-Cysteine helps in making glutathione, a key cellular antioxidant, and supports collagen formation which contributes to skin, hair and nail health. Vitamin C in the product boosts absorption and activity of this amino acid.
