NOW® D-Ribose Pure Powder delivers 100% pure Bioenergy RIBOSE®, a natural five-carbon sugar that fuels your body's cellular energy factory. Unlike everyday table sugars that get burned up for quick heat, D-Ribose is the direct raw material your heart and muscles use to build ATP (adenosine triphosphate)—your body's universal energy fuel. Every serving provides 5,000 mg of clinically tested ribose powder to support workout recovery, relieve post-exercise fatigue, and keep your cellular batteries fully charged.
Most standard sports drinks rely on simple six-carbon sugars like dextrose or sucrose. These sugars spike your bloodstream quickly and often lead to an energy crash. D-Ribose is fundamentally different: it is a unique five-carbon pentose sugar (chemical formula C5H10O5) that does not follow the standard sugar-burning pathway, but instead works directly inside cells to rebuild your core energy molecules [1]. Choosing pure Bioenergy RIBOSE® powder gives you the full clinical 5-gram serving in one easy scoop, saving you from swallowing 6 to 8 giant capsules every single day [2].

Think of every cell in your heart and muscles as a tiny electronic device powered by a rechargeable battery. That battery molecule is called ATP (adenosine triphosphate) [1]. Whenever you sprint, lift weights, or stay active, your cells break ATP down into smaller pieces (ADP and AMP) to release energy [2].
During intense physical work or periods of stress, some of these energy pieces break down completely and wash out of your cells. To replace lost ATP and build fresh batteries, your cells must have a specialized pentose sugar called D-ribose (C5H10O5) [3].
Under normal conditions, your body makes D-ribose through a very slow assembly line called the pentose phosphate pathway [1]. Because this assembly line runs at a slow trickle, it can take up to 72 hours for exhausted muscles to fully replenish their energy stores [2]. Taking NOW® Bioenergy RIBOSE® acts like a direct supply line: it gives your cells pre-formed ribose to make PRPP (5-phosphoribosyl-1-pyrophosphate), jumping past the slow enzymatic roadblock to rebuild fresh ATP in hours instead of days [1, 4].
Mix 1 1/2 level teaspoons (approximately 5 grams) daily into 4 to 8 ounces of water, fruit juice, or your favorite shake. Because D-Ribose absorbs quickly and can gently nudge blood sugar downward, it is best taken with or right after a meal or alongside a small carbohydrate or protein snack [1].
For daily wellness, taking your full 5-gram serving with breakfast keeps cellular energy pools topped off. On intense exercise days, try splitting your dose: take 2.5 grams about 30 minutes before training to fuel active muscles, and take the remaining 2.5 grams in your post-workout shake to jump-start cellular ATP recovery [2].
D-Ribose pairs perfectly with Creatine Monohydrate: creatine recharges existing battery molecules by providing phosphate, while D-ribose builds brand-new battery backbones from scratch [3]. It also works hand-in-hand with CoQ10 and L-Carnitine to support heart cellular metabolism [4]. If you take prescription blood sugar medications, space them at least 2 hours apart from D-ribose and consult your doctor to ensure balanced glucose levels.
NOW® D-Ribose is a fine crystalline white powder packaged in an 8 oz (227 g) tub. It dissolves easily in cold water or juice with a few quick stirs of a spoon—no clumping, chalkiness, or gritty sediment at the bottom of your glass. It eliminates the need to swallow handfuls of large capsules.
D-Ribose is naturally sweet (about 60% as sweet as table sugar) with a clean taste and no bitter chemical aftertaste. It has a mild, clean aroma and a natural off-white to white crystal appearance. Natural color variations can occur between production batches. This product is packaged and sold by weight rather than volume, so some natural powder settling during transit is normal.
Other Ingredients: None. You get 100% active Bioenergy RIBOSE®. There are no flow agents like magnesium stearate, no anti-caking silicon dioxide, and no hidden maltodextrin. The tub contains a small, sealed freshness packet to keep ambient humidity out of the powder. Keep this packet inside the tub and do not eat it.
After opening, store your container in a cool, dry, dark place. Always close the lid tightly after each use to keep moisture in the air from causing the natural sugar crystals to harden.

NOW® D-Ribose has a mild, clean, natural sweetness that is roughly 60% as sweet as table sugar, with no bitter aftertaste or chemical smell. Because it is a 100% water-soluble powder, it dissolves easily into 4 to 8 ounces of water, juice, unsweetened tea, or a post-workout recovery shake with a quick spoon stir.
Table sugar (sucrose) and dextrose are six-carbon sugars that your body breaks down quickly for heat and quick energy, which spikes insulin and often causes an energy crash. D-Ribose is a specialized five-carbon pentose sugar (C5H10O5) that does not enter the standard sugar-burning cycle; instead, cells use it directly as the building block to rebuild ATP cellular energy molecules in your muscles and heart [1, 2].
Each 5-gram serving contains 20 calories and 5 grams of total carbohydrates. If you are doing a strict zero-calorie water fast, those 20 calories will technically break your fast. However, because D-ribose does not spike insulin like regular sugars, many athletes take it right before or after fasted training, or simply take their daily serving during their normal eating window.
Yes! D-Ribose works hand-in-hand with creatine monohydrate. While creatine donates phosphate molecules to recharge depleted ADP into ATP, D-Ribose supplies the raw structural backbone needed to construct brand-new ATP molecules [3]. You can also safely mix it into warm tea or oatmeal, as D-Ribose is heat-stable under normal food preparation conditions.
The clinically validated serving size for D-Ribose is 5,000 mg (5 grams). Standard supplement capsules generally hold 750 mg to 1,000 mg each, meaning you would have to swallow 5 to 7 bulky pills every day to get the same amount. Pure powder gives you the full clinical dose in just 1 1/2 teaspoons, saves you money per gram, and eliminates extra capsule binders.
