How to use

One capsule a day. That is the whole routine.

1

Take one capsule daily

Swallow one capsule with a glass of water, ideally alongside a meal or as advised by a medical professional.
2

Store it cool

NAC has a naturally sulphurous smell. Keeping the pot in the fridge reduces it.
3

Keep it consistent

A steady daily intake matters more than the time of day.

You got questions we got answers


Just one. A single capsule provides 600mg of N-Acetyl Cysteine.

NAC has a high sulphur content, which gives it a distinct odour some people describe as rotten eggs. This is completely normal and confirms genuine N-Acetyl Cysteine. It does not affect quality or safety, and storing the pot in the fridge reduces it.

Yes. The capsule shell is plant-based HPMC and the formula contains no animal-derived ingredients.

No. It is free from lactose and gluten, with no artificial colours or preservatives.

120 capsules at one a day is a four-month supply.
