Metagenics N-Acetyl-L-Cysteine (NAC) 90 Capsules

N-Acetyl-L-Cysteine (NAC) is a highly bioavailable form of L-cysteine, the amino acid your body uses to produce glutathione, or the body’s ‘master antioxidant’. Glutathione plays a critical role in neutralising free radicals, supporting liver detoxification, and strengthening immune response, particularly in the lungs and respiratory tract.

NAC is especially useful when your diet lacks protein-rich foods like meat, cheese, or eggs. Whether you’re looking to support healthy detoxification, immune health, or promote long-term cellular health, NAC is an effective solution.

Key Features 

• Glutathione Precursor: Supplies L-cysteine, the limiting amino acid in glutathione production.
• Liver Detox Support: Supports phase II liver detoxification and cellular defence.
• Highly Bioavailable Form: 500mg of stable, easy-to-absorb N-Acetyl-L-Cysteine per capsule.
• Normal Sulphur Scent: NAC naturally contains sulphur; its slight odour is completely normal.

How long before I feel an effect?

NAC may have an instantaneous beneficial effect on health (within a couple of hours), however many people who decide to take, or who are recommended to take NAC, may have more chronic health issues whereby benefits may not be seen for weeks and total resolution may take 2-3 months. For the best advice of dosage and frequency which is suitable for you, please ask a nutritionist.

What are the benefits of NAC?

NAC helps the body to maintain glutathione levels, which protect our cells from oxidative stress and damage against free radicals. This in turn supports immune and liver health, cognitive function and healthy ageing.

Who is this product suitable for?

As well as those on restricted diets such as vegans or vegetarians, anyone looking to support their glutathione levels may find this stable and absorbable form of NAC supplementation beneficial. It may be particularly useful for older adults due to the fact that plasma cysteine and glutathione levels tend to decline with increasing age.

Doseage

 1 capsule of NAC three times daily, on an empty stomach, or as directed.

Metagenics supplements should not be used as a substitute for a varied diet and healthy lifestyle. Results may vary between individuals.
