It also helps support respiratory & immune health and the liver's detoxification function. Additionally, NAC antioxidant activity supports brain health and a healthy inflammation response for overall cellular health and well-being.†

 Is it safe to take NAC daily?

NAC supplementation is associated with minimal side effects. Studies with a dosage up to 3,000 mg per day have shown that NAC is safe and well-tolerated. If you are pregnant, nursing, taking any medication, or have a health condition, consult your healthcare practitioner before taking this product.

Is NAC the same as Glutathione? Which one should I take?

NAC and liposomal glutathione both provide antioxidant support but in different ways. NAC helps your body produce more glutathione naturally, making it an excellent choice for daily cellular health support. Liposomal glutathione provides direct supplementation of the master antioxidant without requiring activation, designed for when your body may benefit from direct antioxidant supplementation during times of high cellular stress.

Great product! I have faith

"Great product! I have faith and trust in MegaFood's supplements!"

Lisa A. (5/5)

no smell and effective

"No bad smell. Took this upon recommendation after shingles episode. Dosed high for 6-8 weeks (1,200) then maintenance (600). 1. Sleep was amazing! Dreams out of a movie which were crazy and definitely tied to supplement. 2. Stopped my constant dripping nose and morning congestion as a side benefit. I can tell almost immediately when I’ve skipped 3-4 doses because dripping nose comes back. When I couldn’t get this in Amazon or Whole Foods I switched brands and I can hardly stand the smell of other brands (fishy?). I’m going to have to order direct and please come to Costco! I love this brand of B vitamins too!"
