What is N-Acetyl L-Cysteine?
N-Acetyl L-Cysteine (NAC) is a naturally occurring compound within the body. However, it is considered a semi-essential amino acid as it is produced by the body through other amino acids, specifically methionine. NAC is not only a powerful antioxidant but the precursor to another compound found in the body called glutathione, a compound that offers antioxidant effects as well as immune support. Glutathione is arguably the most powerful antioxidant in your body and needs replenishing. The range of benefits from these amino acids ranges from assisting in reducing chronic respiratory conditions to brain health. 


N-Acetyl L-Cysteine Potential Benefits May Include:

  • May support detoxification†
  • May support immune system health†
  • May assist in healthy respiratory function†

How Does N-Acetyl L-Cysteine Work?
For the human body to create the amino acid cysteine, it needs adequate amounts of folate and vitamins B6 and B12. The nutrients mentioned above are in both animal and plant-based foods such as beans, lentils, spinach, bananas, salmon, and tuna. NAC also plays a role in working alongside glutamine and glycine to help replenish glutathione, a vital amino acid that helps keep free radicals at bay. In conjunction with replenishing glutathione, NAC promotes brain health.† NAC may also play a role in the body's detoxification process by assisting in the prevention of damage to the kidneys and liver.†


Consider This:
Try pairing with our Chaga Mushroom Extract powder for a potentially improved immune system.†

    It’s not easy to find N-acetyl-cysteine in powder form (in my experience) so I’m thrilled to have this! I want to amp up glutathione in my body and this is the ticket! Love it!

    When I try any supplement I always start slow and increase the dosage. Hard Rhino NAC seems to be safe without and side effects. Well as to the benefits time will tell. I am taking this to increase my glutathione levels.
