The energy supplement of the moment
Start from the basis that our body needs a sufficient supply of purines and pyrimidines to allow it to produce important cellular components, such as genetic material (DNA and RNA), multiple cofactors and certain vitamins and, most importantly, adenosine triphosphate (ATP), a basic “molecular currency” when it comes to intracellular energy transfer.
Ribose is the starting point in the synthesis of relevant cellular connections, meaning that the amount of ribose available in the body determines the speed at which these connections can be produced by our cells and tissues.
What is Ribose?
Ribose is a supplement that can be of great help for leading an active life full of energy. It is also known as pentose and is a simple monosaccharide made up of five carbon atoms.
Its use by all the cells of the body and the fact that it forms an important part of energy metabolism are its main calling cards. Ribose is also involved in building our genetic material, DNA and RNA, certain vitamins and other relevant cellular compounds.
This is why its supplementation (together with creatine) is of great interest in certain conditions such as fibromyalgia, which are characterised by ATP levels below what is considered normal.
Where does the importance of ATP lie?
ATP, or energy, is absolutely essential for the production of high-intensity muscle contractions, after which a phosphate molecule is lost. The good news is that this molecule can be regenerated by obtaining the lost molecule, a process in which creatine is involved.
That said, the regeneration we are analysing is short-term, but there is another process that works over the longer term and on which full recovery depends. This is what will allow you to be ready to train with the required intensity. And it is in this final process that ribose comes into play.

A basic ingredient of life
With this in mind, ribose is a specific type of simple sugar found in the cells of any living organism, whether humans, animals or plants. It is a basic ingredient of life. This is because it is present in most of the foods that make up your diet, meaning that every time you sit down to eat, you are taking in a dose of ribose.
Once it comes into contact with cells, this substance is converted into ATP (adenosine triphosphate) and provides the body with energy. For this reason, an additional supply of ribose is increasingly valued by athletes and sportspeople who use up a great deal of energy during training. Best of all, although the amount of energy may be low, it will be maintained for a long period of time.
As an energy provider for the heart muscle, it is invaluable and is especially recommended for:
- Those who suffer from heart problems
- People who are recovering from a heart attack
- Those who suffer from heart failure
What is the function of Ribose?
Regardless of whether it is a natural substance or a prescription drug, no other compound is capable of replacing the essential role of ribose in regulating the metabolic processes involved in the synthesis of purines and pyrimidines.
Without the presence of these vital structural components, our body would quickly deplete its energy levels and would be unable to produce proteins. In turn, our cells would no longer be able to divide.
Its effectiveness has been demonstrated in all cases, however varied the intended use may be. In this sense, it allows us to:
- Fight fatigue
- Overcome muscle pain caused by intensive training
- Improve physical performance
- Recover from effort and exhaustion
Whatever your case may be, start from the basis that ribose will improve your energy and, therefore, your quality of life.

What does this substance do in the body?
Although there is a lot we could say about this, we are going to try to summarise and reduce the explanation of what ribose does in the body to four points:
- It is a vital nutrient that promotes heart health
- Increases physical performance by providing energy
- Provides energy to the heart muscle, ensuring its healthy function
- Reduces cardiovascular stress caused by an inadequate energy supply
Discover all its effects
You probably already know that the human body produces energy in its cells and that it does so through the sugars it consumes in the diet, especially those derived from adenosine triphosphate or ATP, the body’s main energy provider.
When energy reserves are depleted, they need to be replenished again. This renewal is more important after suffering an illness, being exposed to a stressful situation or experiencing physical wear and tear after sport or intensive training.
As for ribose, it is a special sugar that helps the body stimulate energy production in the cells and replenish their reserves.
For this reason, ribose dietary supplements help, in a completely natural way, with faster recovery.
The main beneficiary of this rapid energy recovery process is the heart muscle, which has to work 24 hours a day and on whose proper functioning the limbs and the rest of the body in general depend. And what happens when its reserves run out? Symptoms of exhaustion and overload for the heart may occur.
After an intense physical training session, ATP may need up to 72 hours to completely regenerate the depleted stores after physical exertion.
If there is not enough ribose, replenishment will not be possible, nor will there be the ability to perform at the same intensity as at the beginning. This means that a longer recovery period is required, or that in the next training session it will not be possible to use the necessary intensity.
This substance has been used in medicine for the treatment of patients with cardiovascular conditions, since it improves the performance of fatigued heart cells.
An ideal supplement for sportspeople
The scientific studies carried out with ribose in sportspeople are still few in number. The reason is simple: its recent use as a food supplement.
In any case, the results seem quite promising, since it has been shown that sportspeople who take the supplement experience a significant increase in strength and explosive energy, as well as faster recovery.
Likewise, ribose supplementation also helps sportspeople by enhancing the effects of other energy supplements such as creatine, carnitine or pyruvate, producing a synergistic effect.
Bear in mind that these supplements require the presence of ATP substrates that only ribose is capable of producing. Maintaining high levels of ATP substrates is what ensures that the other supplements act more efficiently.
Who is it recommended for?
Many people can benefit from the advantages of ribose. However, we are going to list those who may benefit especially from taking it.
So, we are talking about ribose:
- For sportspeople and athletes undergoing frequent training sessions
- People who suffer from chronic fatigue
- Those who suffer from heart problems or circulatory system issues
- For people who work under conditions of high stress, because it may increase their performance
- All people in general, as it is one of the body’s primary energy providers

How is Ribose produced?
In the same way as other vital compounds, ribose is generated in the body through complex biochemical and metabolic processes.
This substance is produced in the body through a metabolic process involving glucose (a simple sugar with six carbon atoms), called the pentose phosphate pathway (PPP) or hexose monophosphate shunt (HMS).
This delay in ribose synthesis in the heart and its muscle tissue also slows energy recovery when reserves are depleted due to illness or physical training.
How do the body’s cells gain energy through D-Ribose?
Behind the complicated name 5-phosphoribosyl-1-pyrophosphate (PRPP) lies the physiologically functional form of ribose, which regulates the metabolic process through which energy bonds are synthesised in all living tissues.
This process is carried out through purine nucleoside phosphorylase (PNP). If the body does not have a sufficient level of PRPP, the energy synthesis process slows down and tissue recovery is delayed.
How and when should it be taken?
Do you want to use pentose to help support your sports performance? Then you should take it before or after training.
Be careful! If competitive sport is your thing, you may need a supply of slightly higher doses to provide your body with the energy it requires. After taking ribose, blood sugar levels decrease, making it highly recommended for diabetics to take it in supplement form.
The human body produces ribose just as it does creatine, although it is not able to do so at the required rate when there is extreme muscle wear, as occurs with the practice of certain sports.
If this is also your case, do not forget the usefulness of supplementing your ribose supply by taking dietary supplements. The same intake is also highly favourable for those suffering from heart problems.
Check your recommended daily dose here
The first thing you should know regarding the intake of ribose supplements is that it is a natural, safe and non-toxic substance. So much so that, as we have been saying, it is found in all the cells of the body.
What are the natural sources of Ribose?
Ribose is present in all foods of animal or plant origin, in different amounts.
If you need to achieve greater physical performance or are going through a particularly stressful period, there is a strong possibility that the amounts of ribose supplied by food are insufficient to meet your body’s needs. This is when you may consider the possibility of taking ribose dietary supplements.

Side effects
Despite being a completely natural substance, there are two known side effects of ribose:
- The first is temporary hypoglycaemia or a decrease in blood sugar levels. Prevent this situation by combining the intake of a high dose of ribose with other carbohydrates.
- The second is mild diarrhoea. This effect is experienced by some people and also occurs when very high doses, above ten grams, are taken.
How does it work in people who exercise regularly?
Clinical research carried out to date reveals that, when 3 or 4 weekly training sessions are performed, the body does not have time to rest. For this reason, the energy accumulated in the heart and muscles does not return to its normal level.
Taking ribose allows the energy of the heart and muscle tissue to be restored more quickly when intensive training is performed.
Maintaining an optimal energy level ensures that the heart and muscles remain in good physical condition, increasing strength and physical endurance and reducing fatigue.
In addition, research has shed light on the fact that taking ribose dietary supplements during exercise reduces the formation of free radicals.
Can it be combined with creatine or other supplements?
An additional dietary supplement of carnitine helps with the metabolisation of fatty acids. Others that also help replenish energy are pyruvate and coenzyme Q10.
In any case, none of the above supplements, by itself, provides cells with the energy they require. In this sense, ribose is the only one that performs this relevant metabolic function, which can be enhanced in combination with the other supplements.
This is because an insufficient energy level does not allow any dietary supplement to offer its maximum capacity, as the basic conditions for them to work are not present.
In short, ribose helps the body produce energy, while the rest of the dietary supplements can help the body use that energy efficiently.
Why are more and more people taking it?
Because in the past, producing D-ribose was too expensive, meaning it was not a dietary treatment within reach of every budget.
At a certain point, new technologies helped reduce production costs, as a result of which ribose became a substance accessible to everyone.
To this, you must add the advantage that ribose is completely safe. More than 70 clinical studies carried out in different laboratories have revealed its effectiveness and the highly beneficial effects it has on the functioning of the heart and muscles.

Ribose and the heart
One of the tested health benefits of ribose is that it improves the natural process of energy synthesis in the body, helping to reduce energy loss during periods of high stress and accelerating its recovery in cells and tissues.
It also helps maintain a strong and healthy heart and muscles. This applies whether you have to complete a triathlon or a regular workout, as well as any other activity.
The heart’s ability to remain active and healthy is related to the amount of ribose available to the body.
It can be said of ribose that:
- It provides the heart with the strength necessary for optimal function
- It keeps the heart and muscles at a healthy level
- It increases the proper functioning of the heart during physical activity or sports training, reducing the stress associated with exertion
- It improves performance during physical activity
Expert opinion
There is unanimity among experts regarding ribose when pointing out that its additional intake helps the body in all situations in which it requires an increase in energy.
Clinical studies have revealed that this vital substance supports optimal heart function, also providing invaluable help to patients suffering from COPD, chronic fatigue syndrome or fibromyalgia and MAD deficiency.
You now have extensive information about ribose. It is up to you to assess whether taking it is appropriate. For our part, we remain at your disposal should you need clarification on any questions that may arise about this monosaccharide.
