## Resource

In this episode of Molecules Matter with Dr. Dan, we break down N-acetylcysteine (NAC)—a powerful molecule that helps your body produce glutathione, often called the “master antioxidant.” Unlike typical supplements that act directly, NAC works upstream by giving your body the building blocks it needs to protect itself from oxidative stress, inflammation, and cellular damage. We explore how NAC functions at the molecular level, including its role in redox balance, neurotransmitter regulation, and mitochondrial protection. We also dive into the scientific literature behind its effects on brain health, addiction pathways, fertility, kidney protection, and more. You’ll learn: • What NAC is and how it’s made • Why glutathione is critical for health • How NAC supports brain function and recovery • Its role in addiction, fertility, and metabolic health • Where the research is strong—and where it’s limited • Evidence-based dosing and safety considerations NAC has been studied in conditions like traumatic brain injury, Parkinson’s disease, schizophrenia, PCOS, male infertility, and acute kidney injury. It is also used clinically to prevent liver damage in cases of toxicity. Typical dose: 600 mg twice daily As always, consult your healthcare provider before starting any new supplement, especially if you have a medical condition or take medications.
