There’s an antioxidant getting a lot of attention lately — glutathione. You’ll see it in IV drip bars, premium supplements, and anti-aging clinics, often called the “master antioxidant.” The interesting thing is that most of what’s said about its importance is accurate. Glutathione genuinely is one of your body’s most important antioxidant defenses. The part … Read more
Here’s something that genuinely surprised me when I first read the research, and it flips a common assumption on its head. When you exercise, your muscles produce reactive oxygen molecules — the very things antioxidant marketing tells you to fear. And it turns out those molecules are a required part of how exercise makes you … Read more
There’s a pattern that shows up again and again in the biology of aging, and once you see it, a lot of things click into place. Many of the systems that keep you functioning well don’t fail suddenly — they gradually produce less of what they need. Hormones decline. Certain enzymes decline. And the cellular … Read more
Cut your finger and within seconds a remarkably coordinated process begins. Blood clots, the area seals, inflammation ramps up to clear debris and fight infection, then new tissue is built and the inflammation resolves. We take it for granted, but every step of that is cells communicating with each other in a precise sequence. And … Read more
If you want one system that quietly determines how well you age, look at your blood vessels — specifically the thin inner lining called the endothelium. It’s not passive plumbing. That lining actively decides, moment to moment, whether your vessels relax and open or stay tight, and it does that job using chemical signals. The … Read more
Most people think of the brain as separate from the rest of the body’s aging — something that either stays sharp or slowly fades, largely on its own. It doesn’t work that way. Your brain is a physical organ made of cells, and those cells run on the same chemistry as the rest of you. … Read more
After writing about cellular health and redox signaling for several months, certain questions come up repeatedly. Here are the most common ones, answered as directly as I can. Is this just another supplement trend? No — and the distinction is important. The science of redox signaling is documented in thousands of peer-reviewed papers published over … Read more
We’re living through a significant shift in how science understands human biology. For most of the 20th century, the dominant model of health and disease was mechanical and reductionist — identify the broken part, fix the broken part. The explosion of molecular biology in the latter half of the century began to reveal the extraordinary … Read more
I want to be careful about how I frame this — I’m not dismissing conventional medicine or encouraging anyone to ignore their doctor’s advice. Medical doctors are highly trained professionals whose expertise saves lives and manages serious disease effectively. What I’m noting is a reality about how medical knowledge evolves and where redox signaling currently … Read more
The word “supplement” covers an enormous range of things. Vitamins, minerals, herbs, amino acids, enzymes, hormones, probiotics — they’re all called supplements, but they work through fundamentally different mechanisms and serve fundamentally different purposes. Understanding those differences helps you make better decisions about what you actually need. Most supplements work by providing raw materials or … Read more
