How It Works
NAC donates cysteine for glutathione synthesis, the body's master antioxidant. Glutathione neutralizes reactive oxygen species, supports liver Phase II detoxification, and maintains immune function. Oral glutathione is poorly absorbed; NAC is the proven workaround.
Glutathione Precursor
Provides cysteine for endogenous glutathione synthesis — more effective than oral glutathione.
Liver Support
Supports hepatic detoxification and may improve elevated liver enzymes over 8–12 weeks.
Respiratory Mucolytic
Thins mucus and supports respiratory health during pollution or illness exposure.

SupplementsCreatine Dose: 5g Daily for Muscle, Bone, and Brain
Take 5 g of creatine monohydrate every day for muscle, bone, and brain. You do not need a separate higher daily dose for bone — the bone research is still early and is studied with lifting, at ordinary doses. Some short brain studies use about 10–20 g a day, split up. That is a research protocol, not the daily dose this guide uses. Saturation from 5 g a day is the default.
