I just want to warn you that high doses of niacinamide are going to shut down your methylation and deplete methyl donors.
This will prevent breakdown of adrenaline, estrogen and histamine and also lead to endothelial dysfunction.
If your estrogen builds up, your RA will feel better because estrogen = ceruloplasmin and ceruloplasmin protects from arthritis, but estrogen slows your metabolism.
Body can only afford to raise estrogen (ceruloplasmin) without negative consequences when your metabolism is high.
Oh my! This is certainly something new Since I am quite new at this don't really have enough understanding for the biochemistry but understood from Haiduts earlier post on RA being a metabolic disease with a dysfunctional glucose metabolism that in fact was reversed in rats with high doses of niacinamide? No mention of effect on methylation. Have to go back and see....Thank you for the input.
