Best Naturals D-Ribose 1 Lb Powder

not sure, but it seems as if its giving me a little bump of energy throughout the day and for my workouts. every little bit helps and this i feel does help. i will most likely order more soon, since using this to start the day with breakfast and then a little for the workouts too, it goes fast. so, it does enough to make me feel i should buy more. however, i did add this along with acetyl l-carnitine ad around the same time and take both together to start the day and with workouts. i take many supplements together but, because of this, i also try to really pay attention if something is worth it or not(things get expensive fast). so, i will be trying another jar of this because it seems to help.
