N-Acetyle Cysteine

by Alex Royal

 N-Acetyle Cysteine is a type of herb which has demanded the spotlight over the last few months especially in the realm of immunity.

It has mucus thinning properties, reducing the recurrence and severity of respiratory infection. It also inhibits viral replication and modulates IL-6. This is a marker of inflammation status, which helps to tone inflammation down. It further helps to synthesis glutathione to act as an antioxidant to protect lungs against oxidative stress and free radicals.

Food sources include allium veggies:

  • Onions
  • Garlic
  • Leeks
  • Shallots

Foods high in cysteine and methionine include:

  • lean meats
  • fish
  • oats
  • lentils
  • eggs
  • sunflower seeds.

Interestingly, bone broth supports pathways that allow NAC production.

NAC supplementation ranges from 600 - 900mg twice a day but PLEASE speak to a doctor or dietitian before starting this.
