D-ribose is an aldopentose sugar with a five-carbon ring structure. It is essential for gene expression and regulation and to code and decode genes. It forms the structural backbone of RNA and DNA. The body needs d-ribose to synthesize several adenine nucleotides, including adenosine monophosphate (AMP), adenosine triphosphate (ATP), and adenosine diphosphate (ADP). All three molecules are critical for energy storage and transfer. However, ATP has the greatest molecular unit of currency when it comes to energy. It stores and releases energy to cells to catalyze several bodily processes, including nerve impulse propagation and muscle contractions. ATP is also an essential component to synthesize RNA.
D-Ribose may be able to reduce fatigue due to its integral role in synthesizing ATP. One study noted that chronically fatigued participants taking d-ribose supplements experienced significant improvements in their energy levels. The same study reported notable improvements in participants’ sleep, mental clarity, and mood. D-Ribose is also a limiting factor to synthesize ATP. For example, certain pathological conditions and intense exercise deplete ATP to meet the body’s demand for energy. However, the availability of d-ribose limits how much ATP the body can synthesize. By replenishing d-ribose stores, the body can produce more ATP to boost energy.
D-ribose supplements may support heart health by boosting energy availability in heart muscle, improving heart metabolism, and increasing the heart’s ability to tolerate exercise. Several studies have noted that d-ribose helps improve heart function and quality of life for individuals with heart conditions.
D-Ribose may improve pain symptoms by improving energy metabolism. A pilot study reported that d-ribose supplements improved the intensity of the participants’ subjective pain levels. Another all-female study noted that d-ribose improved the participants’ pain levels. Researchers believe d-ribose supplements help attenuate pain by altering how muscles metabolize adenine nucleotides.
D-ribose may enhance exercise performance by replenishing ATP for muscle energy. One study found that d-ribose outperformed a placebo sugar when restoring ATP after intense exercise. Researchers hypothesized that increased ATP synthesis may reduce soreness and exercise recovery. Another study reported that improvements in exercise performance are particularly notable in individuals with lower fitness levels. Participants with a lower VO2 max were able to sustain their exercise performance with a reduced perceived rate of exertion.
Most individuals tolerate d-ribose supplements without experiencing side effects. Some individuals may experience mild gastrointestinal side effects, such as nausea, upset stomach, or diarrhea. Individuals with diabetes should not take d-ribose supplements without consulting their physician, as it may lower blood sugar. Individuals with upcoming surgical procedures should abstain from taking d-ribose supplements for at least two weeks before their surgery to avoid problems with maintaining blood sugar.
