Ive had high cholesterol for several months now., as well as plantar fasciitis....its just a byproduct of working more...being on my feet, A LOT...being busier, and not taking time out to take care of a 46 year old body, the way it should be maintained. Add to that, I HATE doctors and hospitals...hence, my need to look at options that will keep me from frequent visits to my primary care and/or hospital. Enter, LE niacin pills. I did run this by my doc', who in turn asked where I would buy them from. So, I showed him...he researched this particular product, before giving my permission. He suggested the 500 mg, for a few mths, at which he would check my liver 'numbers'. Ive been taking it a few weeks now, and lemme tell you something. The pain in my right foot from the plantar fasciitis, is COMPLETELY gone. And there was also a weird numbness I was feeling in my both arms that started in both forearms and stretched down to my pinkie finger and my ring finger, on each limb (probably a relatively mild case of carpal tunnel syndrome) . And now, all of that numbness is virtually gone. basically, the little aches and pains that are just apparent enuf to annoy the hell out of you, on a daily basis, are pretty much a memory. So, I have no complaints about this product. All I asked from the beginning, was for it, to do, what I wanted it to do. And it has. think about it..this pill has basically saved me thousands of bucks, of what a lot of folks would have surgery for. Im not sure what going to the gym, in concert with what this stuff does for you, but I gotta think, getting the blood pumping and eating well, would probably help this pill, do what it does, even more, regarding your cardiovascular system, anyway. A neighbor/friend told me there is such a thing as a topical niacin solution, that helps nourish your face...as well as firming it up, so to speak. I looked it up, and there are several brands. That will be my next pit stop with niacin..again. it will save me a lot of money that a lot of people would spend on botox and face lifts. And I dont need a face lift. But I do love the idea of having a fresher looking face that has been enhanced by a niacin product that cleared up age lines and bags under my eyes. Im what you call, "a very happy customer".
