So I knew this was mitochondrial but it was revealed when I received my genome. We have issues with our electron transport chain; Complex I (ND1 and ND4) and Complex III (MT-CYB).
So diet and lifestyle was crucial in getting me off all of my meds, and I was on a lot. High dose riboflavin was a huge help.
Getting complex I to work well helps with the heart since it increases NAD. Also getting enough ubiquinone from diet helps. I get it mostly from seafood like Salmon and Liver. I might try and take a CoQ10 supplement soon. But the fact that we make it endogenously makes me think it is not needed. Statins will stop the production of CoQ10 by lowering FPPP production which is why they fail to help people with Heart Disease.
Balancing the flow and the oxidative stress from the mitochondrial electron transport chain is crucial.
