Hi, I have been given 4 supplements by my integrative pain med doctor for energy and muscle pain. I was asked to take up to 1000mg of coenzyme Q10, 100mg twice a day of a B1,B6, and Malate, twice a day corvalin (d-ribose) and 1000mg twice a day of carnitine. I was able to get up to 800 mg of Coenzyme Q10, the twice daily dose of d-ribose, and 200mg of the B1,B6, malate combo. I was on each of these for about at least 4 days and then I got the carnitine in and took 500mg in the morning.
