Need some schooling on vitamins and supplements please?

In my case supplements did not help and I've stopped all of them after ?? 15 years. I was "diagnosed" as "systemic," meaning something on the order of Lyme or Lupus. They have tested for "everything they can think of" and still don't know what causes my pain.

I took fish oil, Omega 3, Glucosomine, condroiten forgotten what else
