Founder story

I built what I couldn't find

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. Of every dose you swallow, only a sliver actually reaches the brain. The rest never gets in.

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 ferries past the blood brain barrier.

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 to lift absorption across the board.

Some things made it in on the first try. Some I added, dropped, brought back, dropped again. Some I tested in pairs to see if they amplified each other. 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. Sharper than I was at 30. Focus is back. Memory is back. Mood and motivation, absolutely on. The shape I felt closing in. It opened up instead.

I built what I couldn't find.

Maybe it works for you too.
