Most people really are low in vitamin D. The reasons have nothing to do with moral failure or weak willpower. The “right amount” depends on age, body fat, sun exposure, health status, and how broken your metabolism already is. Vitamin D can be helpful, boring, or harmful depending on how casually you treat it. As with most things in health, the danger lies not in deficiency or supplementation. The danger is oversimplification.

Vitamin D is technically a hormone, not a vitamin in the classic sense. Your body produces it when ultraviolet B light hits your skin, converting cholesterol into vitamin D3. That alone should tell you something important. This is not kale dust. This is a system that evolved when humans spent most of their time outdoors, half-naked by modern standards, not under fluorescent lights and SPF 50.

AG1 promises energy, immunity, gut health, and a sharper brain. What it really delivers is expensive placebo dust dressed up as science. I break down the junk research, the marketing tricks, and what actually moves the needle for your health. Spoiler: it is not a $100 tub of green powder.

They’ve been selling powders, pills, and miracle blends to us for decades. Most of it belongs in the same category as pet rocks and mood rings: fun to talk about, useless in reality. But creatine? That little scoop of chalky dust might actually be the rare supplement that delivers. Not because it’s trendy, not because some influencer with abs the size of Kansas said so, but because the science backs it up.

If you’re a Boomer staring down the aches, the slower recovery, the muscle loss that creeps in like a thief in the night, creatine could be the edge you didn’t know you had. It’s cheap, it’s safe, and it’s been studied more than most prescription meds. The question isn’t whether it works, it’s whether you’re ready to drop the snake oil and try something that does.
