Alzheimer’s Breakthrough with Dr. Josh Helman, MD How Nitric Oxide Restores Brain Health and Prevents Alzheimer’s With Dr. Nathan Bryan
Nov 6, 2025
Dr. Nathan Bryan, an international leader in nitric oxide biochemistry and therapeutics, explains why nitric oxide may restore blood flow and brain health. He discusses nitric oxide’s roles in vascular and metabolic drivers of Alzheimer’s, oral microbiome links, clinical trial designs, practical steps to boost NO, and emerging NO‑based products and therapies.

Nitric Oxide As Root Cause Of Alzheimer's
- Nitric oxide deficiency underlies Alzheimer's by causing insulin resistance, focal ischemia, and protein misfolding in the brain.
- Restoring nitric oxide improves insulin sensitivity, mitochondrial function, and blood flow, preventing misfolding and cognitive decline.
Nitric Oxide Is A Master Signaling Molecule
- Nitric oxide is far more than a vasodilator: it downregulates adhesion molecules, reduces vascular inflammation, and corrects immune dysfunction.
- Loss of endothelial NO production precedes structural cardiovascular and dementia changes.
Stop Killing Oral Bacteria To Restore Nitric Oxide
- Stop practices that destroy oral nitrate-reducing bacteria: avoid fluoride toothpaste, antiseptic mouthwash, and unnecessary antibiotics.
- Also wean off antacids and eliminate dietary sugar to restore oral microbiome and nitric oxide production.
