Move over kale smoothies and meditation apps, here comes creatine, the humble 50-cent supplement that gym bros have been hoarding like it’s the Fountain of Youth all along. Science now claims this muscle-building marvel is not only for flexing biceps but might just moonlight as an anti-aging potion that could give Alzheimer’s a run for its money. Apparently, it’s the “best-kept secret” that your grandma should be sneaking into her morning oatmeal instead of her afternoon bingo chips.

Forget the luxury anti-aging creams costing you a mortgage — scientists say creatine packs a punch for brain power, muscle mass, and heart health, all while being cheaper than a cup of artisan coffee. And side effects? Well, maybe a little water retention, so you might look a bit puffier, which is apparently totally worth it if it means you can remember where you left your keys and still out-squat the teenager down the street.

So, if you thought creatine was just for sweaty gym selfies and bro-hugs, think again. It’s the new Swiss Army knife of supplements: builds muscle, slows aging, and could make dementia a thing of the past. Who knew that pumping iron and popping pills at 50 cents a pop might just be the elixir of life? Get your tubs of powdered magic before the pharma companies wake up.
