Support glutathione, your body's master antioxidant, with 900 mg of NAC in a single capsule, for your MOOD · MIND · MEMORY.

Glutathione protects every cell in your body from everyday oxidative stress, including the cells of your brain, liver and lungs. Your body makes its own glutathione, but it needs cysteine to do it, and cysteine is often in short supply. N-acetyl-L-cysteine (NAC) is a stable, well-absorbed source of cysteine. Brain Basics Ultra-Pure NAC delivers a full 900 mg per capsule, so you get a potent dose without taking a handful of pills.

Nearly twice the NAC of typical supplements

Many NAC supplements provide just 500 mg per capsule. Ultra-Pure NAC delivers 900 mg, nearly twice as much, in a single capsule. That gives your body a meaningful daily amount of NAC to support the key pathways it depends on:

• Glutathione production: more cysteine available to build your body's master antioxidant
• Liver health: support for the liver's natural detoxification and antioxidant defenses
• Neurological health: support for healthy brain function and the brain's defenses against oxidative stress
• Respiratory and immune health: support for healthy lungs, normal mucus clearance and immune function

No handful of pills and no guesswork. Just one high-potency capsule a day.

Frequently asked questions

What is glutathione, and why does it matter?
Glutathione is an antioxidant your body makes in every cell. It helps neutralize free radicals, supports the liver's natural detoxification work and helps recycle other antioxidants such as vitamins C and E.

Why take NAC instead of glutathione?
Glutathione taken by mouth is largely broken down during digestion. NAC supplies cysteine, the building block your body most often runs short on, so your cells can make glutathione themselves.

Why is NAC so widely researched?
NAC has been studied by researchers for decades for its role in antioxidant defense, neurological health, liver health, lung health and immune support.

Can I take NAC with other Brain Bean products?
Yes. NAC pairs well with Brain ReCharge™ and Brain ResQ™ for comprehensive antioxidant and cellular energy support.
