Supporting the Body’s Own Glutathione Pathway
Glutathione is a tripeptide produced naturally by the body — often described in nutritional science as the body’s ‘master antioxidant’. Rather than supplying glutathione directly (which has poor oral bioavailability), this complex targets the body’s own production pathway, bringing together NAC, Alpha-Lipoic Acid, Glycine and L-Glutamine — the amino acid precursors most associated with glutathione synthesis — alongside Quercetin, Vitamin C and black pepper extract.

A Whole-Pathway Approach
Most single-ingredient supplements address only one part of the glutathione story. This complex covers the pathway more broadly — three amino acid precursors (NAC as cysteine source, glycine, glutamine), the cofactor ALA, the polyphenol quercetin, and Vitamin C. Each ingredient has a distinct role in the biochemistry nutritional scientists associate with glutathione production and antioxidant metabolism; together they provide broader pathway coverage than any single compound.
Adding It to Your Daily Routine
Take four capsules per day with water. At four capsules daily, the 120-capsule bottle covers a full month. The formula is unflavoured and free from artificial colours, encased in HPMC vegan capsules — no gelatin. Take with or without food; consult your health practitioner before use if you are taking medication or under medical supervision.
Understanding the Ingredients
Glutathione is synthesised from three amino acids: cysteine, glycine, and glutamic acid. N-Acetyl-L-Cysteine (NAC) is a stable, orally bioavailable form of cysteine — the rate-limiting amino acid in glutathione synthesis — and is the most widely studied precursor in this context. Alpha-Lipoic Acid is a naturally occurring compound found in mitochondria that has been studied for its role in cellular antioxidant metabolism. Quercetin is a flavonoid found naturally in foods such as onions, apples, and berries. Vitamin C (ascorbic acid) is a water-soluble nutrient with several recognised functions, including contributing to the protection of cells from oxidative stress.
Inside the Formula
N-Acetyl-L-Cysteine (NAC) — 600mg per daily serving — a stable, bioavailable cysteine derivative; the rate-limiting precursor in the body’s glutathione synthesis pathway.
Quercetin — 510mg per daily serving — a plant-derived flavonoid polyphenol naturally present in fruits and vegetables.
L-Glycine — 400mg per daily serving — one of the three amino acids that form the glutathione tripeptide structure.
Alpha-Lipoic Acid (ALA) — 200mg per daily serving — a naturally occurring compound studied in mitochondrial and antioxidant metabolism. Present in both R- and S-ALA forms.
L-Glutamine — 100mg per daily serving — a glutamic acid-related amino acid involved in the glutathione tripeptide precursor pathway.
Vitamin C (L-ascorbic acid) — contributes to the protection of cells from oxidative stress and to the reduction of tiredness and fatigue. Included alongside the amino acid complex.
Black Pepper Extract (Piper nigrum) — included in the formulation for its naturally occurring piperine content.

Frequently Asked Questions
Why NAC rather than glutathione directly?
Oral glutathione has poor bioavailability — the molecule is largely broken down before it can be absorbed. NAC provides cysteine, the rate-limiting amino acid in the body’s own glutathione synthesis. Supplementing the precursor rather than the end-product is the approach most nutritional scientists favour for this pathway.
How many capsules should I take each day?
Four capsules daily with water. Do not exceed the recommended daily serving. Take with or without food.
Is this supplement suitable for vegans?
Yes. The capsule shell is HPMC (hydroxypropyl methylcellulose), not gelatin. The formula is free from gluten, lactose, and soy.
Can I take this if I am pregnant or breastfeeding?
Always consult your health practitioner before taking nutritional supplements if you are pregnant, breastfeeding, taking medication, or under medical supervision.
