## What is D-Ribose?

D-ribose is often referred to as “[molecular currency](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5959283/),” as it plays a critical role in supporting [energy production](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5959283/). Every cell in the body requires energy as [adenosine triphosphate (ATP)](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5738882/) to properly function. However, ATP production may become depleted during heightened energy demands, such as [high-intensity exercises](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5738882/), or with certain conditions, such as [cardiovascular disease](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5943027/). Impaired ATP production may result in [muscle fatigue](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8005739/) or [prolonged recovery periods](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5738882/), and the body may rely on alternative metabolic pathways to create cellular energy. This is where D-ribose comes into play. D-ribose has a unique role in its ability to “bypass” a rate-limiting enzyme ([glucose-6-phosphate dehydrogenase](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5738882/)) in the [pentose phosphate pathway](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5738882/) required for ATP production, which may promote proper energy production during high energy demands. D-ribose is also essential in building various compounds in the body, such as [nucleotides, coenzymes, and nucleic acids](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5738882/). Clinical studies also suggest that D-ribose may attenuate the [effects of oxidative stress](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5738882/) in the body, especially during exercise. D-ribose is produced endogenously and can be obtained through supplements. 

## D-Ribose and Exercise Recovery

Research suggests it may take [days for muscle ATP status to return to normal](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5738882/) after prolonged or high-intensity exercise. For athletes, this may result in excessive [muscle fatigue](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8005739/), [cramping, pain, and stiffness](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5959283/), or an [inability to sufficiently recover](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5738882/) in the subsequent days after playing sports or exercising. D-ribose has been shown in [human studies](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5738882/) to promote proper ATP production during and after exercise, which may support muscle performance, recovery, and exercise metabolism. 

A [double-blind, crossover study](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5738882/) of healthy adults (n = 26) compared the effects of 10 g per day of D-ribose supplementation to a control while undergoing 1 hour of high-intensity interval exercise. The adults receiving D-ribose exhibited improved exercise performance and significantly lower rates of perceived exercise and creatine kinase. While there are conflicting results, [previous human studies](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5738882/) have demonstrated that athletes administered D-ribose supplementation before sports play or exercise exhibited increased power output, muscular power assessment in weightlifting, and overall muscular strength.

## D-Ribose and Cardiac Function

It is understood that [proper cardiac function requires healthy ATP production](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8005739/). [Ingwall and Weiss](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5943027/) proposed that a “[failing heart is energy starved](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5943027/).” [Myocardial ischemia](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5943027/) (or decreased blood flow and oxygen to the heart muscle) is commonly found in those with [atherosclerosis](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5943027/) and is often an underlying condition of [cardiovascular disease](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5943027/). Research suggests that cardiac ischemia is associated with [insufficient ATP status](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8005739/). For this reason, [pre-clinical and pilot clinical studies](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5943027/) have investigated and concluded that D-ribose may be clinically beneficial for those with cardiac dysfunction. However, more clinical research is needed before major conclusions can be drawn.

In various [human studies](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5943027/), patients with congestive heart failure who were administered D-ribose supplementation exhibited improved [diastolic function](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5943027/), [ventilatory efficiency](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5943027/), and [subjective quality of life and physical function](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5943027/) as part of an overall healthy lifestyle. Research also suggests that D-ribose may improve [mitochondrial function](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5959283/), potentially [increasing ATP production and promoting cardiac performance](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8573443/). Mitochondria produce [99% of the ATP in the body](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5959283/).

Proper ATP status is crucial in supporting heart health and athletic performance. Due to the unique role of D-ribose in energy production, it may promote cardiac function and exercise recovery.
