★★★★★ "I won't go back to high street supplements. The difference in quality is something you can actually feel." Susie
N-Acetyl Cysteine NAC Capsules give you NAC on its own, the form of the amino acid cysteine your body uses to make glutathione, its main antioxidant. Each capsule provides 375mg and you take one a day with food. One pot holds 60 capsules, which is a 60 day supply.
Benefits of taking NAC
Cysteine is the amino acid that limits how much glutathione a cell can make, so NAC is the usual way to raise it. It feeds your own production rather than supplying the finished molecule, with a long history of use behind it.
- Your own glutathione production gets the cysteine it is limited by.
- Cells get antioxidant support against oxidative stress.
- The liver gets the glutathione it uses to process compounds for removal.
Who benefits
N-Acetyl Cysteine NAC Capsules are most useful for:
- People who want a glutathione precursor at a known amount, usually on a practitioner's suggestion.
- Anyone already taking glutathione who wants the raw material alongside it.
- Those who want a single ingredient capsule with nothing added.
If you would rather take the finished molecule, Glutathione Capsules give 200mg of reduced glutathione in each.
What is in it
Each capsule provides 375mg of N-acetyl cysteine. The other ingredients are cellulose and the vegetable capsule shell. It has a sulphur smell, which is normal for the compound. N-acetyl-L-cysteine and acetylcysteine are other names for it.
How to take it
Take one capsule a day with food.
Diet and allergens
The capsules are suitable for vegans and vegetarians. They are free from gluten, dairy and nuts.
Quality
The capsules are made in the UK in a GMP certified cleanroom facility accredited to ISO 9001 and ISO 14001. Every batch is traceable from raw material to finished product. Like every supplement Nutri Tailor stocks, they are practitioner grade and guaranteed additive free.
Common questions
NAC or glutathione, which should I take?
NAC supplies cysteine, the amino acid that limits how much glutathione your body can make, so it raises glutathione by feeding your own production. It is well absorbed, well studied and the cheaper of the two, so most people start here. Glutathione capsules supply the finished molecule, part of which is broken down in the gut before absorption.
How much NAC should I take a day?
Take one capsule a day, which gives you 375mg.
When is the best time to take NAC?
With food, at any time of day.
Can I take it with other supplements?
Yes. It is often taken alongside Glutathione Capsules, so the body gets both the raw material and the finished molecule.
Does NAC have side effects?
NAC is well tolerated at this amount. The sulphur smell of the capsule is normal and not a sign of anything wrong.
Why capsules rather than tablets?
A capsule is a cellulose shell around the powder, so it needs none of the binders or coating that hold a tablet together.

Frequently asked questions
What is N Acetyl Cysteine good for?
N Acetyl Cysteine provides antioxidant support against oxidative stress.
NAC or glutathione: which should I take?
NAC supplies cysteine, the amino acid that limits how much glutathione the body can make, so it raises glutathione by feeding your own production; it is well absorbed, well studied and the cheaper of the two. Glutathione capsules supply the finished molecule, but a good part of it is broken down in the gut before absorption. Most people start with NAC. Glutathione on its own suits people who have been advised to take it directly. NAC is sold as one form, so there is no form to choose between.
When should I take antioxidants?
Take with food for best absorption.
What causes oxidative stress?
Pollution, UV exposure, processed foods, stress, intense exercise, and normal metabolism all generate free radicals.
Who is NAC best for?
People who want a glutathione precursor at a known dose, usually on a practitioner's suggestion, people already taking glutathione who want the raw material alongside it, and anyone who wants a single-ingredient capsule. There is no authorised health claim for NAC, so Nutri Tailor does not promise an outcome from it.
What is NAC?
N-acetyl cysteine, a stable form of the amino acid cysteine, which is the amino acid that limits how much glutathione a cell can make. Each capsule provides 375 mg. It has a sulphur smell, which is normal for the compound.
Why capsules rather than tablets?
Tablets need binders, fillers and a coating to hold their shape. A capsule is a cellulose shell around the powder, so it carries no binders and breaks down quickly once swallowed.
