Frequently Asked Questions

What is NAC?

N-Acetyl-Cysteine (NAC) is the acetylated form of L-cysteine — the rate-limiting amino acid in glutathione synthesis.*

Why is this formula called NAC Regulators rather than just NAC?

This formula includes molybdenum and riboflavin-5-phosphate, which provides FAD, a coenzyme involved in the glutathione system.*

Can I take NAC long-term?

As with any supplement, consult your healthcare professional if you are on medications or have specific health conditions.
