Question 1

Why does NAC smell like sulphur?

Accepted Answer

NAC is a sulphur-containing amino acid, so a sulphur or eggy smell when you open the tub is normal and not a sign the capsules have gone off. Some people also notice a stronger smell in their urine, breath or sweat. Keeping the lid tightly closed and taking your capsule with a large glass of water helps.

Question 2

Can NAC cause bloating or gas?

Accepted Answer

Some people notice mild bloating, wind or an unsettled stomach, especially in the first week or two. These effects are usually mild. If your stomach feels unsettled, try taking your capsule with a light meal rather than on an empty stomach. If symptoms continue, stop taking it and speak to your GP or pharmacist.

Question 3

Why does NAC+ include selenium and molybdenum?

Accepted Answer

Each capsule adds 25 mcg of selenium and 45 mcg of molybdenum to the 600 mg of NAC. Selenium is needed for glutathione peroxidase, one of the enzymes that works alongside glutathione, and contributes to the protection of cells from oxidative stress. Molybdenum contributes to normal sulphur amino acid metabolism, and NAC is a sulphur amino acid. Most NAC supplements leave both out.

Question 4

Does NAC deplete selenium?

Accepted Answer

There is no good evidence that NAC depletes selenium. We include selenium because the glutathione system relies on selenium-dependent enzymes, not because NAC removes it. Each NAC+ capsule provides 25 mcg of selenium, about 45% of the daily reference intake, which covers that cofactor without taking you anywhere near the upper limit.

Question 5

What is the difference between NAC and glutathione?

Accepted Answer

NAC (N-acetyl cysteine) is a stable form of cysteine, the building block your body uses to make its own glutathione. Glutathione itself is a larger molecule, and much of it is broken down in the gut when swallowed. That is why many people choose NAC as the precursor instead.

Question 6

When is the best time to take NAC?

Accepted Answer

Take one capsule a day, ideally on an empty stomach with a large glass of water and away from coffee. Morning or evening both work. The main thing is taking it consistently at a time that suits you.

Question 7

Can I take NAC every day?

Accepted Answer

Yes. NAC+ is a once-daily capsule, and one tub is a three-month supply. If you plan to take it long term or have a medical condition, check with your GP.

Question 8

Can I take NAC with magnesium or other supplements?

Accepted Answer

There is no known interaction between NAC and magnesium, and many people take both. If you take prescription medication, check with your pharmacist first.

Question 9

Who should not take NAC?

Accepted Answer

NAC+ is not suitable if you have cystinuria or take nitrate medications (such as glyceryl trinitrate for angina). Consult your doctor. Speak to your GP before taking it if you are pregnant or breastfeeding, have asthma, or take any prescription medication.

Question 10

Is NAC+ vegan?

Accepted Answer

Yes. NAC+ is vegan certified and uses a plant-based HPMC capsule, with no animal-derived ingredients.
