I will happily leave a review. 1st bought this on Amazon after researching something that might help with my getting dizzy so often due to hypoglycemia. I thought hey, if it improves the blood flow, it might help, right? Well, I am now on my 3rd bottle and only take 3 droppers (which is about half the dropper full) each morning, sometimes mixed in the coffee. I can honestly say that I go longer without the need to eat to keep balanced, and I no longer get up from my desk and feel like I'm going to pass out or get out of the car after an hour drive and have to hold on to the fender until the dizziness goes away. This alone is worth it to me but beyond that, I have energy all day, and my mind is much more clear than ever before. I am 62, avoid anything prescription, and I would highly recommend this to anyone, and have in fact. Yes, the cayenne has a bite to it but you get used to it. Oh and it seems my legs don't get the lite cramps from sitting at the desk too long. Give it a try, it's worth it for your overall feeling to get thru the day without getting run down.
