Biotest recommends up to 400mg @ 15% rosavins.
When taking this herb, do you go for the total amount or base it upon the % of rosavins?
When I took it, I find one with the same profile as Biotest's. I would think of it like fish oil... I take a brand that has 750mg EPA+DHA per 1000g. I take enough for the EPA+DHA I am looking for, and not the total fish oil.
