These really work! I break them in half and dissolve them on each side of my mouth for about 20 mins prior to working out, etc. Youll just notice that you wont hit the wall as soon as usual.

Well the first day I took one I felt nothing the second day I took one on an empty stomach with glass of water and boy it gave me a burst of energy I got everything done in an hour which would normally take me 6 hours! And they taste great!

I admit that I was skeptical when I ordered this product...my skepticism was unfounded...they actually support stronger output and longer duration of physical activity...road biking to be more precise. I can ride longer and harder since Ive been using this product. Pricey yes, does it deliver value in your training yes. I will buy this product again.

I am new to using Beet'ums and have used them on the last 5-6 rides/training sessions. I have taken them between 30-45 minutes of riding as suggested. For a one hour training session that wasn't too challenging, 1 seemed adequate. Longer or harder sessions I took 2. On a 3 hour hard ride I took 2 to start and 1/hour thereafter. I don't know if that's what is intended or not? In any event, they seem to work. The breathing seems easier on the hard efforts (raising the VO2 max somewhat). Not a miracle by any stretch but a slight improvement... enough to stay with the faster riders and not get dropped.
