How does NAC help the body?

  • free radical protection; a powerful antioxident
  • helps sustain both cysteine levels in the blood, and glutathione levels inside the cells, a major antioxidant
  • replenishes levels of antioxidant glutathione (GSH), which is often deficient with age and in chronic illness
  • improves insulin sensitivity
  • helps support cellular health and liver function
