D-Ribose
A natural sugar that rapidly replenishes ATP stores for energy recovery and cardiac support.
Also known as: Ribose • D-Ribose Sugar
Overview
D-Ribose is a naturally occurring five-carbon sugar that is a fundamental building block of ATP (adenosine triphosphate), the body's primary energy currency. Unlike glucose, ribose bypasses the slow pentose phosphate pathway and directly enters ATP synthesis. It is particularly beneficial for replenishing energy stores after intense exercise or in conditions of impaired energy metabolism.
Key Benefits
ATP Replenishment
Directly provides the ribose backbone needed for ATP synthesis, accelerating energy recovery.
Exercise Recovery
Speeds recovery of muscle ATP stores depleted during intense exercise.
Cardiac Energy
Supports energy production in heart muscle, particularly in heart failure.
Fatigue Reduction
May reduce fatigue in chronic fatigue conditions and fibromyalgia.
Dosage & How to Take
5-15 g daily in divided doses.
| Purpose | Dose | Notes |

| General energy | 5 g/day | In divided doses |
| Athletic recovery | 5-10 g/day | Before and after exercise |
| Cardiac/chronic fatigue | 10-15 g/day | In 3 divided doses |
Best Time to Take
Divided throughout the day.
