I purchased this supplement after reading Nathan Hatch’s book, F Portion Control. I took 250mg this morning and about a half hour later, I felt AMAZING. Probably way to early to post, but I normally get a bad reaction to nearly all supps. I took this for a couple reasons: mainly iron overload, dry eyes, Seb. Derm. and I’ve had the Angular Chelitis (sp?) in the corner of my mouth a few times. I’ll report back later...
