N-acetylcysteine (NAC)

Mechanism

Your body's most important internal antioxidant is called glutathione, and the rate-limiting step in making it is having enough of an amino acid called cysteine. NAC is the cleanest, most studied way to deliver that cysteine. Pairs with glycine (the other half of the glutathione recipe) which sits in the same packet.

Why we use it

Perimenopause is an oxidative-stress moment — hormones drop, inflammation runs higher, and your body's antioxidant defenses fall behind. NAC restocks the most important antioxidant your body makes. We pair it with glycine because both are needed to build glutathione; one without the other does much less.

How we dose it

Hericea uses 1,200 mg per serving (per PM packet). The clinical trial range that anchors this dose is 600–1,800 mg/day.

1.2 grams — the standard antioxidant-support dose. Higher doses (around 7 grams) have been studied for cognitive reversal in older adults; we are deliberately not making that claim at this dose.
