I use Superfood and IF#1 and #2 all the time. Superfood is daily, with periodic use of the others. I am blood type O.
The ONLY thing that I have noticed with this and I'm not sure it's related to blood type or not, is sometimes after drinking the superfood I feel just the tiniest bit queasy. It is very mild and goes away quickly and then I feel better than ever. I was wondering if it was the spirulina in the Superfood because type O's are not supposed to have that.
But I'm so glad you're getting this stuff. It is awesome.
