The Difference Between a Symptom and a Cause

Modern health advice is overwhelmingly organized around symptoms. Tired? Here’s an energy product. Achy? Here’s something for that. Not sleeping? Here’s a sleep aid. Each one targets the thing you can feel. And there’s nothing wrong with relief — but if you only ever chase symptoms, you can spend years managing effects while the underlying … Read more

The Question I Ask Before I Take Any Supplement

After three decades in the supplement industry, I’ve watched thousands of products come and go. Most make the same basic promise in slightly different packaging. Over the years I’ve boiled my own decision down to one question that cuts through nearly all of the marketing: does this address a mechanism, or does it just add … Read more

Why “More Antioxidants” Isn’t the Answer You Think It Is

Walk down any supplement aisle and the message is everywhere: more antioxidants, higher ORAC scores, stronger free-radical protection. It’s an appealing story because it’s simple. Free radicals damage cells, antioxidants neutralize them, so more must be better. The problem is that the biology doesn’t actually work like a simple counter. I’ve spent over 30 years … Read more

Where to Go From Here With Cellular Health

If you’ve been reading this blog for a while — or if you’ve just found it and gone back through the archive — you now have a more complete picture of cellular health and redox signaling than most people ever develop. You understand that your body produces redox signaling molecules naturally, that production declines with … Read more

The Most Common Questions I Get About Cellular Health — Answered

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

How to Think About Long-Term Health Investment vs. Short-Term Fixes

Health decisions involve a kind of economics that most people haven’t explicitly thought through. Short-term fixes have immediate, visible payoffs. Take a pain reliever and the pain stops. Take a sleep aid and you sleep. Take an energy supplement and you feel more alert. These interventions are easy to justify because the benefit is immediate … Read more

The Difference Between a Supplement and a Signaling Molecule

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

What Independent Labs Found When They Tested ASEA

One of the most important questions you can ask about any health product is: who tested it, and what did they find? For ASEA, the answer to that question involves the Pacific Northwest National Laboratory — one of the United States Department of Energy’s national laboratories, operated by Battelle Memorial Institute. This is not a … Read more

How I Evaluate Health Research Without a Medical Degree

One of the most common things people say when they encounter health research is “I’m not a scientist, I can’t evaluate this.” It’s a reasonable thing to feel — research papers are dense, the methodology is technical, and the conclusions are often hedged in ways that make them hard to interpret. But here’s what I’ve … Read more
