B12 because that's the default answer for everything. Month of that. Nothing.
Magnesium because someone at work swore by it. Another month. Same crash at 2pm. Same cold hands.
Iron even though my levels were fine. Because at that point I was arguing with my own bloodwork. If the test says I'm fine and I don't feel fine then maybe the test is wrong. (It wasn't wrong. I just didn't have the right information.)
CoQ10 at $45 a bottle for 2 months. The only thing that changed was my credit card statement.
Fish oil because the label said "supports circulation." That word. Circulation. It was the only thing I had to go on.
None of it did anything. I kept a running list in my head. What I tried. What it cost. What it didn't do. And the list was getting long and expensive and I was getting tired of being tired.
Then beet powder. Because that one I actually understood. Nitrates convert to nitric oxide. Nitric oxide tells blood vessels to relax and stay open. More blood flow. More oxygen. Real studies. Real mechanism. I committed for 6 weeks. Stained my counter pink. Tasted like wet dirt every morning. And I kept going because this was the one with real science behind it.
My legs still hit empty at the same spot on the same street.
I could explain the mechanism to you right now. Draw you a diagram. And it still didn't help me.
That was the question I carried for months. Why does something that makes scientific sense still not work.
