The perfect ally
Alex | 27/03/2026
I bought HSN's NAC on the recommendation of my nutritionist to improve liver detoxification and strengthen the immune system, and the experience has been impeccable. What I value most is that it comes in 300mg vegetable capsules, a very versatile dose that allows you to adjust your daily intake as needed.
A critical customer says:
I have not noticed any effect
María jesús | 28/10/2025
I have just finished the bottle and have not noticed any effect. Hopefully its antioxidant power as a glutathione precursor is beneficial to the body. I will continue to take it, but in powder form.

Nac - Antioxidant 300 mg Capsules
The tablets are a great size and easy to swallow. It doesn't have the strong sulfur smell that other products do. It doesn't cause heartburn, and digestion is fine. I always take it with meals. It's still too early to see results since I haven't even finished the bottle yet, but like any supplement, I think results become apparent after 3–4 months.
