D-Ribose
Five-carbon sugar that forms the backbone of ATP — accelerates cellular energy recovery in heart and muscle tissue.
D-Ribose is a simple five-carbon sugar that forms the backbone of ATP (adenosine triphosphate), the body's primary energy currency. While the body can synthesize ribose, supplementation may accelerate ATP regeneration after intense exercise or in conditions where energy production is compromised. It's particularly studied for heart health and chronic fatigue conditions, where cellular energy may be depleted.
Provides the ribose backbone for ATP molecules
Accelerates regeneration of depleted ATP pools
Supports heart muscle energy needs

5g 2-3 times daily
Loading: Can start with 15g/day divided into 3 doses, then reduce to maintenance
Take with food
| Form | Type |
|---|---|
| 🧪D-Ribose powder | Recommended |
| 💊Capsules | Alternative |
| 💊Chewable tablets | Alternative |
Powder is most cost-effective for the relatively high doses needed. Has a mildly sweet taste.
Minimum: 2 weeks
Optimal: 8 weeks
Cycling: Not required
Note: Divide doses throughout the day for best absorption. Taking with meals may help prevent blood sugar fluctuations.
Improved cellular energy and reduced fatigue
Quicker ATP replenishment after intense exercise
Better heart function in those with compromised hearts
May lower blood sugar; monitor if diabetic
Limited data; consult healthcare provider
May be beneficial; consult cardiologist
May enhance blood sugar lowering effects
Monitor blood sugar; may need dose adjustment
Tip: Take with food; monitor blood sugar
Tip: Reduce dose; take with food

“Low dose creatine (60 mg/kg/day) did not cause side-effects but high-dose creatine (150 mg/kg/day) worsened the symptoms of myalgia.Authors' conclusions Although there was low quality evidence of improvement in some parameters with creatine, oral sucrose, ramipril and a carbohydrate rich diet, none was sufficiently strong to indicate significant clinical benefit.”
