Frequently Asked Questions
What is NAC?
N-Acetyl-Cysteine (NAC) is a form of the amino acid cysteine. It's a precursor to glutathione, an antioxidant the body makes itself.
Why does it smell a bit eggy?
NAC contains sulphur, and that's where the smell comes from. Every NAC capsule smells like this. It hasn't gone off. Keep the lid on and you'll stop noticing it.
Why not just buy the cheapest NAC I can find?
A lot of cheap NAC online comes from sellers you can't trace, with no way of knowing where it was made or to what standard. Ours is made in the UK in a GMP and BRC certified facility: a full 600mg of pure NAC in every capsule, no blends, 120 capsules a tub. And it's backed by our 30-day money-back guarantee, even if you've opened it.
What does it work out at per day?
120 capsules for £14.99. That's 12.5p a day on one capsule, or 25p on two.
One capsule or two?
Start on one a day for the first week. NAC can unsettle some people's stomachs, so this lets you see how you get on. After that, stay on one or go up to two, one in the morning and one later in the day. A tub lasts four months on one a day, or two months on two.
When should I take it?
Between meals with a glass of water is best. If it unsettles your stomach, take it with food instead.
Can I take it with my other supplements?
Yes. It's a single ingredient, so it slots in alongside the rest of your supplements without doubling anything up. If you take prescription medication, check with your GP or pharmacist first.
What if it's not for me?
Take it daily for at least 14 days. If it's not right, email us within 30 days of delivery and we'll refund you, even if the tub's open. You don't need to send it back.
Who shouldn't take it?
It's not for children, or if you're pregnant or breastfeeding. If you take medication or are under medical supervision, check with your GP first.
