Supplements

I am curious to hear anyone's positive, negative, or neutral experiences with the following for their LONG Covid / Post-infectious syndrome treatment plan: Nattokinase, CoQ10, NADH, ALCAR, Vitamin C, Magnesium Glycinate. I've had these recommended by several providers, but no strong commitment to the best approach for benefits. There is limited information on short or long-term risks with these supplements. Thoughts?
