I haven't tried that particular supplement, Floradix worked well for me, plus eliminating anything with tanins in it, green tea, coffee, choc. etc. I try to take my supplement with vit. c and I also don't eat dairy within an hour or so of taking it. I am sure that you have heard of all of these, but just thought I would mention them if it could help at all. I have low blood pressure and low iron as well and I can totally relate to not having enough energy.
