I just talked to my neighbor who is challenged with RA, and that is an autoimmune disease. For some reason I thought people who have these diseases and take biologic drugs for their issues, cannot take Vit C, grape Seed Ex etc to strengthen their whole body immune system and she said oh no, she is taking at least 3K of Vit D daily and when she gets enough money buys the Grape Seed Extract.

So I'm happy to hear this, she is a person who has always been into supplements but this RA hit her a few yrs ago and bam what a life change she has gone thru.

The RA weakens her immune system and the drug she takes helps slowing down the damage..but the Vit C, etc work on her whole system. Glad I got that from her mouth, she is up on it all for her body.
