At first, I didn't know if the supplement caused my blood pressure to rise (10%). I called and was assured that they wouldn't think so, but they couldn't advise me on this matter. I took the supplement in reduced doses for the first week and after ward the regular amount, no side effects. My grandson says, "Papa, your skin looks great, what are you doing?" I showed him the pamphlet, and he says it looks like it is working.
At 88 I've always had plenty of energy and no disabilities, but I do think the supplement does give you a slight added edge. I'm not tired or exhausted after doing the manual work that I still do (yard work, carpenter work, and just plain labor). I take it every day at mid-morning, that seems to work best for me. Good product.
Bottom Line: Yes, I would recommend this to a friend
