Reverses brain damage
96 people found this helpful
This supplement has been a lifesaver for me. After years of substance abuse, I felt lost until I discovered NAC's potential to repair brain damage. Within a week or two, I felt about 70% better, which was astonishing for such a simple remedy. I continue to take it daily for its anxiolytic effects and as a preventive measure against alcohol-related brain damage. I truly believe it saved my life.

Brain fog eliminated
31 people found this helpful
After successfully taking NAC a few years ago, I tried it again and it was worth it. The Dr's Best NAC Detox Regulators helped restore my glutathione levels, cleansing my liver and brain rapidly. By the second day, the brain fog was gone, and I slept deeply for eight uninterrupted hours. The quality is excellent; these capsules are essential for detoxifying the body from toxins.

BRILLIANT! I cannot stress enough how beneficial NAC is for me. I have MS and had been suffering from severe fatigue and brain fog. After using NAC for about two months, I feel much better; the brain fog is virtually gone, I am sleeping better and feeling less stressed! I recommend it to everyone! Thank you, iHerb!

Increased glutathione
2 people found this helpful
Liked, I recommend Doctor's Best NAC Detox Regulators. They enhance the production of glutathione in the brain and liver. This product boosts glutathione levels, supports enzymes that neutralise natural and artificial toxins, and promotes healthy functioning of crucial proteins. The three nutrients – NAC, selenium, and molybdenum – support glutathione production, which has been shown to be effective.

Mood improvement experienced
23 people found this helpful
It was effective for symptoms of depression. Initially, I bought it cheaply for skin health and detoxing, then stockpiled it for emergencies. This year, feeling a bit depressed, my brain was constantly tired with no motivation. I discovered NAC can alleviate such feelings; taking one capsule brought relief and cleared my brain fog that day. I'm grateful for having purchased it.

Improves cognition during withdrawal
2 people found this helpful
I appreciate using NAC; it’s an excellent detox supplement that genuinely helps during hard drug withdrawal, improving mood and cognition. However, I prefer other brands as the selenium content limits my dosage. The optimal NAC dose for detox should be 1000-2000mg daily, which exceeds what's in these tablets.

Insomnia assistance
1 people found this helpful
Great for liver and brain health, this is my first time using NAC, which I chose based on research suggesting it may enhance brain function and help those with OCD and depression. It has significantly alleviated my insomnia when paired with Inositol and Magnesium. The capsule size is manageable and tasteless.

Not suitable for everyone
After reading great reviews, I hoped this product would help my brain fog. Unfortunately, it exacerbated my symptoms, and I felt unwell while using it. Those with MTHFR mutations should consult their doctor before taking this product.

Helps memory recall
1 people found this helpful
I take one capsule in the morning and another at night to combat brain fog, and I've found it immensely helpful. It works quickly, enhancing my cognition and memory. After recovering from Covid and a reaction to antibiotics, I've felt the difference in my brain health after adding it back into my diet. Of all my supplements, this one stands out as particularly beneficial.
