It started in my family. Grandma. Early dementia in her 60s. The woman who taught me to read forgot my name. Mom got it earlier. Her 50s. I watched it take them piece by piece. The stories first. Then the faces. Then the small things, like how to hold a fork.
At 38, the words started to slip. A name on the tip of the tongue. A meeting I half remembered. Focus that used to be free took work. I felt the same shape closing in around me.
So I went looking. For anything that fights back.
I remembered the articles. The ones I'd skimmed a year or two before. Creatine. Brain energy. Memory. Mood. Headlines you flick past when they don't apply. They applied now. So I went back and read them properly. The science was loud and the science was clear. But there was a catch. Brain creatine plays by different rules than muscle creatine. It is tightly regulated and it builds slowly.
So I built around the catch.
I started with creatine alone. Better, but slow. So I went deep on the science. Brain creatine isn't just about how much you swallow. It's about how much your body actually makes, uses, and holds onto.
Then I started layering. Glycine and arginine, the building blocks the body uses to make its own creatine. Betaine, a methyl donor that powers the synthesis. The B vitamins, B12, folate, B6, that keep the engine running on the inside. Magnesium, because ATP doesn't work without it. CDP-Choline, because the brain runs on phospholipids and acetylcholine, not just creatine. A sliver of BioPerine, standardized black pepper extract.
Some things made it in on the first try. Some I added, dropped, brought back, dropped again. Some I tested together. Some I tested alone. Some I cut because they didn't pull their weight.
Two years. On myself. Add. Remove. Test. Repeat. My kitchen counter became a lab. Every ingredient had to earn its spot, or it was out.
Then one morning I noticed I wasn't fighting for focus anymore. It was just there. The way it used to be.
I'm 40 now. I built the thing I went looking for. The shape I felt closing in. I stopped feeling it close.
I built what I couldn't find.
Maybe it works for you too.
