Frequently Asked Questions (Q&A)
What is this product?
NOW Foods NAC is a US original import supplement providing 600 mg of N-acetyl cysteine plus 25 mcg of selenium (from L-selenomethionine) per vegetarian capsule. NAC is a stable form of the non-essential amino acid cysteine. The product is suitable for vegetarians and GMP quality assured.
What are the key ingredients and their benefits?
This sulfur-containing amino acid acts as a stabilizer for the formation of protein structures, and is also necessary for the formation of glutathione — the body's master antioxidant. Selenium is an essential trace mineral that facilitates the production of several important enzymes, rounding out this cellular-health formula.
Who is this product suitable for?
It suits adults who want antioxidant and detox support at the cellular level — a favorite among those focused on liver wellness and healthy aging. The capsules are vegetarian/vegan friendly.
