Mg Chelate, 125 mg caps, 3 x a day, Natural Factors
Recommended daily dose by the USDA is 400 mg. I think that is "elemental."
It should be noted that of the 125 mg in a Mg chelate capsule that Mg is likely a small minority of the 125 mg; the rest is whatever the Mg is chelated to.
Given that the immune systems of our bodies are so busy then we probably are chronically depleted of many nutrients.
I hope this helps,
HLA-B27 neg; Mis-diagnosed with fibromyalgia in mid-20s.
Vague AS symptoms in 20s and early 30s (no diagnosis).
During age 47 (2015) from NSAID use developed complete axial inflammation (started from from skull and progressed down to sacrum). Included psoriasis. Trigger in scull was reverse blockage in a SCUBA mishap in 2013. Straw that broke the camels back was over use of NSAIDs. NSD works well but not perfect. Strong involvement between symptoms and gut integrity.
