What you should know:
D-ribose is a sugar (pentose / aldose) that takes part in atp synthesis, the simplest form of chemical energy present in all living organisms (from bacteria to humans). It has been shown that greater availability of d-ribose aids atp synthesis and therefore increases energy reserves. D-ribose represents a substance of enormous interest from both sports and a therapy point of view. D-ribose can be synthesised by the human organism and is present in food (especially meat).
For these reasons, D-ribose is useful in strenuous and/or prolonged physical exercise, for both muscles and heart, within normal limits, need to restore the ATP content. Otherwise, an imbalance would be created between supply and demand of energy. This situation occurs when the dephosphorilation of ATP into ADP and then into AMP goes even further, producing adenosine, inosine and hypoxanthine, products which, released from the cell, would be lost to the effects of a possible recovery of the adenine nucleotides and therefore the energy reserves. The re-use of some of these catabolytes is possible through the so-called process of metabolic recovery (“salvage pathways”).
As mentioned, D-ribose can be formed by the organism in the pentose-phosphate cycle, especially in the liver and adipose tissue, beginning with glucose. However, in physiological conditions, the speed of its synthesis is decidedly low if compared to the cellular content of adenine nucleotides (especially ATP) and their speed of use as energy. The distribution process of the tissues that produce it and those that use it is still unknown. This knowledge implies that a wider availability of ribose for biosynthesis of nucleotides is not easy. Therefore, the intake of D-ribose to increase biosynthesis of the adenine nucleotides is useful.
In the heart muscle, the restoration of adenine nucleotides through taking ribose, and the consequent normalisation of the physiological parameters, has been widely documented experimentally and clinically in heart patients. The possibility of D-ribose to sustain ATP synthesis in any conditions represents an important possibility and opportunity in sports. Various research has in fact shown that an intake of D-ribose determines greater energy availability and improved physical performance.
An intake of ribose (1-3g per day) has no negative effects whatsoever. Only in very high doses (0.5g/kg weight) equal to an intake of 30-35g, does ribose produce a slight increase in insulinemia, which is reflected in a reduction of glycemia not greater however than 15% of the basal value. Normally blood concentrations of ribose are 20mg/litre (value taken from Claudio V.S. and Lagua R., 1991, page 312). An intake of a few grams considerably increases the blood levels of D-ribose that is already present.
Indications for use
SPORT:the use of d-ribose, given its high energy contribution, is recommended for all athletes who have 3 or more training sessions per work, both aerobic and anaerobic. An intake of d-ribose aids the reformation of the basal levels of muscular atp, which decrease considerably with exercise and which therefore come back to normal after a few days.
Dose:the most normal dose is 2 to 5 grams per day, divided before (10-30 minutes) and after training.
DAILY LIFE: D-ribose is recommended when a rapid and safe tonic/energiser is required.
Dose: 2-5 grams during the day.
Warning: an intake of more than 35-40g of D-ribose can cause symptomatic gastric problems.
