Reputable brand
Good quality NAC supplement from a trusted brand. The 1,000 mg dose is effective and convenient, especially for antioxidant and liver support. Tablets are solid and a bit large, but manageable with water. I noticed improved overall clarity and respiratory support with consistent use. No stomach upset or negative side effects. Great value for the quantity.

Very good product
People don’t know that NAC ingredients is basically Sulfur and don’t understand why smells like sulfur, they’re big but I don’t have problems with big sizes, NAC activates Glutathione so the liver does his job detoxing the body Very good product 100% recommended

My New Supplement Journey
I just started taking NOW Foods NAC (N-Acetyl-Cysteine) supplements this week, so it's too early to report on personal results, but I'm optimistic based on what I've heard! Several of my friends with chronic inflammation issues have been raving about these, calling them "miracle workers" for liver protection and reducing their overall inflammation. The capsules are easy to swallow and I haven't experienced any digestive upset, which was a concern I had when starting any new supplement. The NOW Foods brand has a good reputation for quality, which factored into my decision to try this specific NAC product. I'm taking them consistently as directed and plan to give them the full recommended time to work before making any judgments. My main goals are supporting liver health and addressing some joint inflammation I've been experiencing. I'll definitely come back and update this review in a few weeks once I've had enough time to observe any effects. For now, I'm cautiously optimistic based on the experiences of people I trust!

Recover your childhood lungs! Great for history of breathing issues or needing a diver’s breathe.
Helps me breathe very well. Wish there were a cheaper alternative but best i’ve found :) Can start to feel the effects at about 3000mg a day after maybe 3 nights. You start to inhale bigger. Noticeable decrease in health if I stop for maybe a month.

Muy buen suplemento. Las cápsulas son fáciles de tomar y me gusta que la marca tenga buenos estándares de calidad. El NAC es conocido por apoyar la protección antioxidante y la salud celular. Estoy muy satisfecho con esta compra. N-acetil-cisteína aporta 600 mg por cápsula y se usa como apoyo antioxidante.

No criticism with the product at all, I just underestimated the size of the tablets (previously consumed smaller 750mg tablets and capsules). I'm not good with big tablets, however can get them down with something viscous like orange juice.

After listening to the Huberman Lab podcast, I purchased a bottle of the supplement. However, after taking one pill, I woke up extremely dizzy. I stopped taking it, and after half a day, I felt fine again. A week later, I tried again, but 8 hours later, I experienced vertigo-like dizziness. I immediately stopped taking it, and it's clear that the supplement is causing this reaction. Unfortunately, I can't return it.
