You might want to ask her doctor about anti oxidants. My mother had RA and her surgeon pointed out about 6 months ago when she was really not doing well that if she lived in the third world he'd think she had an anti oxidant defficiency. She began taking more Vit C - 1.5g, 400 I.U. of Vit E and 600mg of ALA (Alpha Lipoic Acid) - her most recent tests show a marked improvement in both her Rheumatoid factor and her ECR (don't ask me what that one stands for!). They have their fingers crossed but it looks like she may be heading toward Remission.
