Its versatility and impact on metabolic and hormonal health, particularly for women with PCOS*, has led to NAC becoming one of our most bought & loved supplements. Paired with regular exercise and a healthy diet, it can be a supportive aid in your journey toward balance.

Can NAC be taken with birth control?

Yes


Can I take more than once daily?

The dose of NAC used in clinical trials has ranged from about 600 mg to 3,000 mg per day, typically divided into two or three servings. Generally because most customers are taking other products also, only one capsule per day is generally needed.


Why does my NAC smell rotten?

The odour you smell is likely from the sulphur that is part of NAC (N-acetyl-cysteine), this is completely normal and why it is in a capsule and not a powder.

Take 1 capsule per day, ideally in the mornings.

Combined effort

I’ve started using this as well as Balance and the spearmint supplements. Together they’re helping to regulate my period and finally lose fat! The only reason I didn’t give this 5 stars is because I struggle a bit with the taste. It’s only for a moment though

NAC experience

Unfortunately, my experience wasn’t good using NAC. This supplement made me feel extremely tired and lethargic. It had a sedative effect and I felt unable to complete my daily activities. I’m sure NAC works for some individuals, but it just wasn’t right for me.

Game changing supplement!

NAC has been a game changer in curbing my post meal sugar cravings and keeping me energized and motivated through the day. I still feel the mid-day slump on some days but I'm a constant WIP and this supplement has definitely boosted my progress
