I started taking beet capsules I picked up at HomeGoods, I instantly stopped being tired, one pill per day worked. It didn't seem to matter what brand, any seemed to work and I gave them to friends and they had the same results. Give them a try at this price if they don't work give them to a friend and they probably will for them, but so far, no one who has tried them hasn't had the result of not being tired, with no jangle and being able to sleep at night. We've all done it with only one capsule a day. Amazing!
