Megyn Kelly sat down with Gary Brecka recently to talk about some health topics that keep showing up in headlines: molecular hydrogen, mineral salts like calcium, and the little supplement called creatine. The claims range from “life-changing” to “useful,” and that’s exactly why Americans need clear thinking, not hype. Below I break down what the science says, what the risks are, and what you should actually consider before buying the next miracle in a bottle.
Hydrogen: The tiny gas with big promises
Molecular hydrogen (often called hydrogen therapy or hydrogen-rich water) has gotten attention because it may act as an antioxidant and lower inflammation. Early studies show it can reduce markers of oxidative stress in some people. That sounds good — who doesn’t want less inflammation? But the evidence is still early. There are small trials, promising lab studies, and some real patients who say they feel better. Still, it’s not a magic cure. If you’re curious, hydrogen-rich water or controlled inhalation are the usual ways people try it. Just don’t expect it to erase poor diet and lousy sleep overnight.
Calcium and mineral salts: Essential, but don’t overdo it
Calcium is key for bone health. But more isn’t always better. High doses of calcium supplements have been linked in some studies to problems like kidney stones and the build-up of calcium in blood vessels. That’s why doctors now often say get most calcium from food — think dairy, leafy greens, and fortified foods — and be careful with pills unless a test shows you need them. Also remember the whole mineral team matters: vitamin D, magnesium, and vitamin K2 help direct calcium to bones rather than arteries. In short: test first, supplement second.
Creatine: Cheap, proven, and underused
Creatine gets a bad rap because bodybuilding bros popularized it, but it’s one of the best-studied supplements out there. Creatine monohydrate improves strength, power, and muscle mass. It also shows benefits for brain health, some sleep measures, and may help older adults keep muscle and function. For most healthy people, 3–5 grams a day is safe and effective. Worries about kidney damage are mostly for those who already have kidney disease; healthy adults who use normal doses don’t need to panic. If you want real performance or aging benefits, creatine deserves a look.
Bottom line: Be skeptical, not cynical
Here’s the conservative take: be wary of hype and learn to read the fine print. Molecular hydrogen is interesting but still early. Mineral salts like calcium matter, but sloppy supplementation can hurt more than help. Creatine is inexpensive, safe for most people, and backed by solid research. Do the sensible things first: eat well, sleep more, stay active, and get basic labs from your doctor. Then, if you’re still curious, try a tested supplement with clear dosing — and not the one your influencer pal hawks between ads. Your health won’t be fixed by a single product, but smart, cautious choices can make a real difference.
