Is a hidden molecule in your food and water silently fueling cancer, Alzheimer's, and Parkinson's? Could the supplements you trust every day be making it worse?
Dr. Stephanie Seneff is a senior research scientist at MIT (published in PNAS, Frontiers, FASEB) with a career studying nutrition, biology, and toxicology.
In this conversation, she explains why deuterium — a heavier form of hydrogen — may be the most underrated driver of chronic disease, why cancer might be the body's repair response to deuterium-damaged mitochondria, and why most supplements may backfire.
We discuss:
◾ Why deuterium may be the most important molecule you've never heard of
◾ How glyphosate stops your body from clearing deuterium
◾ The two supplements you should stop taking immediately
◾ Why she says: "I don't believe in supplements"
◾ Why chemo may be working backwards on cancer
◾ How to make your gut produce low-deuterium water
◾ The folic-acid-in-pregnancy and autism connection
◾ Why she drinks deuterium-depleted water every day
This is Dr. Seneff's second appearance on Live Longer World. Her first episode on glyphosate is linked below.
