Excellent for Detox, Lung Health, and Immune Support

NAC has become a staple in my supplement routine. I started taking it to support my lungs and overall detox, and I’ve noticed real improvements — especially in breathing and recovery after workouts or long days. It also helps boost my immune system, and I’ve been feeling more resilient during cold and allergy seasons. I usually take one capsule daily with food, and I love that it’s backed by science and supports glutathione production, which is great for liver health and antioxidant protection. Highly recommended for anyone looking to support their overall wellness in a natural way.

High quality product

Pure N-Acetyl-Cysteine for those looking to support their health. While the taste is quite sour and may not be pleasant to some, the quality of the product makes it worthwhile. It’s a great option for those who can handle the tangy flavor to reap its benefits. A little adjustment, like mixing it with juice, can help make it more palatable!

Good deal

I am very content with the product. The price is super good and that's why i often prefer to buy powders. The taste is acidic and has some kind of smell but nothing bad, at least for me. I take it occasionally when i have a stresfull day or too much physical exertion or if it is the flu season. Combine it with glycine and you have the glynac ;)

Excellent Product, Highly Recommended!

I take NAC as part of my antioxidant and anti-aging routine to support my body during periods of stress and increased physical and mental load. I notice better overall recovery and less tension in my body. I really appreciate that the composition is clean and simple. The NOW NAC powder offers excellent value for money, the package size is generous and lasts a long time. The powder has a mildly tangy taste and dissolves easily in water. This is my second purchase and I will definitely order it again.It offers very good value for the price and lasts a long time. This is my second purchase, and I will definitely order it again.

Excellent so far

First time using NAC. First of all, powder almost always beats other formats for supplements in general, being able to dose it is so important. As a hypersensitive person for those things, NAC has massive effect on me from day one. It 's def doing it's thing. That said, glad I have the powder as I'll def have to dose it down :)

Fresh

Just what I needed to make my supplements. You can tell it’s fresh because it smells horrible that’s how they claim you know it’s still active.

Detox and lung support

I’ve been using NAC for a while, and this pure powder form is potent and cost-effective. It helps me feel clearer and breathe better — I notice improved respiratory comfort and reduced oxidative stress. I also like that I can adjust the dosage precisely. Slightly bitter in taste, but mixing it in water or juice helps. A staple in my antioxidant stack.

NAC

I have to say that I’m quite satisfied with the NAC supplement — I take it every day. I started with 150 mg, and the first time I felt a slight headache and some tension and emotional restlessness. By the next dose, I felt better, and after the fourth dose, there was almost no change in my mood. Now I take 500–600 mg daily for its detoxifying effect.

Pure NAC Powder - Great Value

This NAC powder is excellent quality and unflavored, making it easy to mix into water or juice. I take it daily for antioxidant support and immune health. The powder form is more economical than capsules and dissolves well without clumping. NOW Foods consistently delivers reliable supplements at fair prices. Great for anyone looking to add NAC to their wellness routine!
