This vegan-friendly, highly soluble NAC powder features N-Acetyl-Cysteine, a stable form of cysteine and a key precursor to the antioxidant glutathione, which it is preferentially incorporated into. It is naturally sweetened with thaumatin from the Thaumatococcus daniellii plant and flavored with natural berry and superfood extracts. Made from high-quality, practitioner-only ingredients, the formula contains only all-natural components and is produced without gluten, dairy, wheat, egg, soy, lactose, sulphates/sulphites, crustaceans, or nuts; however, the final product has not been tested to confirm the absence of these substances.
