Lamberts N-Acetyl Cysteine (NAC) 300mg is a food supplement that provides 300mg of N-acetyl cysteine in each of its 90 capsules. It is a one to two-a-day formula, so the daily amount can be set at 1 or 2 capsules, and the capsule shell is suitable for vegetarians and vegans.

Key Features

• 300mg of NAC per capsule: NAC is an altered form of the amino acid L-cysteine, which Lamberts describes as the preferred form for supplements because of its stability.
• One or two capsules a day: the directions allow 1 or 2 capsules daily, so the 90-capsule pack lasts between 45 and 90 days.
• Suitable for vegetarians and vegans: the capsule shell is made from hydroxypropyl methylcellulose.
• Made in the UK: produced in premises that operate to pharmaceutical standards of GMP, according to Lamberts.

What is N-acetyl cysteine (NAC)?

NAC is an altered form of the amino acid L-cysteine. L-cysteine is found naturally in high-protein foods such as chicken, yogurt, cheese and eggs. Lamberts notes that people on restricted diets may find it harder to get enough of this amino acid from food.

Why does NAC smell of sulphur?

NAC is one of the few amino acids that contain sulphur, so it has a strong sulphur-like odour. Lamberts states that this is completely normal.

Who should not take NAC capsules?

The label states that this product is not recommended for children, or for pregnant or breastfeeding women.
