About this item
Product details
N-Acetyl-L-Cysteine, or NAC, is a free-form amino acid required by the body to make glutathione. Glutathione supports the body's antioxidant defense system, recognized for supporting healthy aging. Taken by itself, glutathione is poorly absorbed, but NAC facilitates our body's own production of it. It is an especially beneficial supplement for active people, the elderly, individuals exposed to pollution, and anyone else wanting to maintain healthy levels of glutathione. Supports healthy liver, lung, and kidney function. Helps promote healthy immune system function.

Highly recommend this NAC supplement!
I've been using Natural Factors NAC 500 mg for a few weeks now, and I've noticed a real difference in my overall wellness. It's great knowing it supports antioxidant levels and helps with detox, especially for liver and lung health. The capsules are easy to swallow and don't have any weird aftertaste. I also feel like my breathing and energy levels have improved slightly. The quality seems very high for the price, and I trust this brand. Definitely a great addition to my daily routine if you're looking to boost your immune system and overall health
