I have tried many supplements over the years and what has helped me most is treating the deficiencies. I took magnesium and taurine injections off and on for years, this was very helpful. I continue to rub magnesium gel transdermally to keep my levels optimal.
I also take Ubiquinol, but take breaks from it because it makes me feel wired and interrupts my sleep. Not sure it keeps me at baseline. Pacing yourself is the best medicine for this illness.
