Doctor's Best D-Ribose -- 250 g - 8.8 oz
I have been using this product for about six months now. In my opinion I feel like it has contributed to more energy during my workouts.

Didn't work for me
In comparing d-ribose powders, I liked the Vitacost product much better.

My husband takes it with L-carnitine & Co-Q10 for his heart.

My cardiologist told me to get this supplement for my heart. I feel that it is definitely helping and the price at Vitacost is the best!

i love this d ribose in powder form. It takes about a month to really kick in. It improves my energy and moods. I take a little more when I need extra energy. I can tell a difference when I don't take it. I'll keep using it.
