After retiring early from having mild muscle disease (CMT MD) ten years ago, I decided to see, study, and test most of those vitamins and supplements like one can get at Walmart , etc.
I've come down to eat well like Salmon, brocolli, dried cherries, olives, walnuts, yogurt.......
I think people are really deficient in 2 things that can be added: Vit D-3 of which I take 5k units/day, and Magnesium.
Now this is where it gets tricky; nearly all stores sell 400mg magnesium oxide which won't absorb, so buy some MAGNESIUM MALATE 1250mg off Amazon, and when you get enough down over a period of a few weeks or less, IT WILL MOISTEN YOUR WHOLE BODY, skin, mouth, etc.
You will wake up in morning breathing incredible, and as pain free as possible.
I like the MAGTEIN also which is based on some attached vit c and crosses the brain barrier but approx 3 -4 times pricier.
You can regulate how many pills you take by your mouth moistness; Whwen I get enough my eyes water a little.
