I can't remember how much I was on at the time, but it was a pretty beefy dose. Maybe 2000mg. We have a ton of natural stuff that does indeed help us, it's just that many of them are blood thinners, and with our lungs being constantly attacked and our inclination to bleed, it's not good. That's why trials are so important. Trying to find a minimum dose that helps and doesn't have a strong impact on our bleeds.
