NOW Foods D-Ribose Powder 16 oz.

NOW® Sports D-Ribose supplies pure Bioenergy Ribose® to support cellular energy (ATP) production and recovery.* Ribose is a simple sugar that occurs naturally in every living cell and forms the structural backbone of ATP — the primary energy currency for all cellular processes.* Demand for ATP is especially high in the heart and skeletal muscle, and ribose supplementation can help maintain optimal energy levels in these hard-working tissues, supporting energy and recovery.* 16 oz (90 servings).

Frequently asked questions

What does D-ribose do?
Ribose is the structural backbone of ATP, the cell's main energy molecule. Supplementing D-ribose can help replenish the building blocks for ATP in hard-working tissues like the heart and skeletal muscle, supporting energy levels and recovery from demanding exercise.*

When should I take it?
Take the powder daily, prior to exercise, mixed into water or a beverage (powder) or with water (capsules). It's often used around demanding training when ATP demand is highest.*

Is it just a sugar?
D-ribose is a simple, naturally occurring sugar, but it's used for its structural role in ATP rather than as a sweetener or fuel carbohydrate. NOW® uses Bioenergy Ribose®, a researched, certified non-GMO source.*

Cautions & interactions

D-ribose is generally well tolerated. Because it is a sugar that can transiently affect blood-sugar levels, talk to your doctor before use if you have blood-sugar concerns or take related medication, and if you are pregnant, nursing, taking any medication or managing a medical condition. Keep out of reach of children.
