The scope of this article is to review knowledge of the effect of purine nucleotide precursors such as D-ribose, AICAR, inosine, hypoxanthine, and adenine on myocardial ischemia-reperfusion injury and highlight potential targets for treating myocardial metabolic and mechanical dysfunction associated with ischemia-reperfusion injury by these molecules.
Musial PT et al. · International journal of molecular sciences (2025)
Depletion of cardiac nucleotides and compromised myocardial mechanical function are linked to both acute myocardial ischemia and decompensatory remodelling of the myocardium in heart failure.
Theoretically, in both acute ischemia and chronic high-demand situations associated with the development of heart failure, an imbalance in the breakdown, salvage, and synthesis of purine nucleotides results in a net loss of purine nucleotides.
It was found that the use of nucleotide precursors can be a potentially effective approach to diminishing ischemia-reperfusion damage.
D-ribose is employed both as a therapeutic agent for enhancing cardiac function in heart failure patients and as a remedy for post-exercise fatigue. Nevertheless, recent clinical studies have suggested a potential link between D-ribose metabolic disturbances and type 2 diabetes mellitus (T2DM) along with its associated complications.
Tai Y et al. · Molecular biology reports (2024)
Additionally, certain in vitro experiments have indicated that exogenous D-ribose exposure could trigger apoptosis in specific cell lines.
This article comprehensively reviews the current advancements in D-ribose's digestion, absorption, transmembrane transport, intracellular metabolic pathways, impact on cellular behaviour, and elevated levels in diabetes mellitus.
It also identifies areas requiring further investigation.
Low dose creatine (60 mg/kg/day) did not cause side-effects but high-dose creatine (150 mg/kg/day) worsened the symptoms of myalgia.Authors' conclusions Although there was low quality evidence of improvement in some parameters with creatine, oral sucrose, ramipril and a carbohydrate rich diet, none was sufficiently strong to indicate significant clinical benefit.
Quinlivan R et al. · The Cochrane database of systematic reviews (2014)
Oral ribose caused diarrhoea and symptoms suggestive of hypoglycaemia including light-headedness and hunger.
In one study, branched chain amino acids caused a deterioration of functional outcomes.
Dantrolene was reported to cause a number of adverse effects including tiredness, somnolence, dizziness and muscle weakness.
On the basis of the remarkable glycation capacity of ribose, the easily predictable cytotoxic effect of the molecule is also highlighted.
Moschini R et al. · Biomolecules (2022)
However, this practice still presents too many critical issues, suggesting that caution is needed.
In fact, there are many possible negative effects of this sugar that we believe are underestimated, if not neglected, by the literature supporting the presentation of the product to the market.
Here, the risks deriving from the use of free ribose as ATP source, forcing ribose-5-phosphate to enter into the pentose phosphate pathway, is emphasized.
Limited dietary modifications were found useful in alleviating chronic fatigue syndrome symptoms, with overall evidence narrow and inconsistent across studies.
Jones K et al. · Australian and New Zealand journal of public health (2017)
Limited dietary modifications were found useful in alleviating chronic fatigue syndrome symptoms, with overall evidence narrow and inconsistent across studies.
This was a phase 2 randomized, double-blind, placebo-controlled trial of 216 patients with HFpEF who were ≥ 50 years old with a left ventricular ejection fraction (EF) ≥ 50%.
Pierce JD et al. · The American journal of cardiology (2022)
This was a phase 2 randomized, double-blind, placebo-controlled trial of 216 patients with HFpEF who were ≥ 50 years old with a left ventricular ejection fraction (EF) ≥ 50%.
There were no significant increases in the septal E/e' or the 6-minute walk test.
In conclusion, ubiquinol and d-ribose reduced the symptoms of HFpEF and increased the EF.
8Exercise tolerance in ischemic heart diseaseRCTCited 7×n=53 · small study2019
However, this needs to be further studied, given that there is no clear evidence that the double product can be used as a surrogate measure of exercise tolerance.
Derosa G et al. · Nutrients (2019)
Health Science in Lissone, Italy.
After six months of study, the cardiac double product at the peak of the load, the delta double product, and the chronotropic index were higher in the active treatment group than in the placebo group.
We can conclude that a supplementation with creatine, D-ribose, vitamin B1, and vitamin B6, in addition to standard therapy and a physical exercise program, seems to be helpful in improving exercise tolerance compared to the placebo in a population with cardiovascular disease.
RiaGev appears to be safe and efficacious in increasing NAD+ metabolome in healthy middle-aged adults, as shown by this study.

Supplementing with 1520 mg RiaGev twice daily for 7 days significantly increased the NAD+ metabolome in blood, especially NADP+ by 27% compared to the placebo group (p = 0.033) and over the baseline (p = 0.007).
Seven-day supplementation with RiaGev significantly (p = 0.013) reduced overall blood glucose without significant changes in insulin secretion (p = 0.796), suggesting an improved insulin sensitivity and glucose tolerance.
The waking salivary cortisol of the subjects steadily and significantly decreased (p = 0.026) in the RiaGev group in contrast to the placebo.
D-ribose supplementation reduces muscle soreness, improves recovery of muscle damage, and inhibits the formation of lipid peroxides.
Cao W et al. · Journal of the International Society of Sports Nutrition (2020)
D-ribose supplementation reduces muscle soreness, improves recovery of muscle damage, and inhibits the formation of lipid peroxides.
Young adult males performing plyometric exercise are likely to realize a DOMS reduction through consumption of D-ribose in 15 g/doses both before (1-h) and after (1-h, 12-h, 24-h, 36-h) exercise.
These results suggest that appropriately timed consumption of D-ribose may induce a similar alleviation of exercise-induced DOMS in the general public.

Whey protein and melatonin have a positive effect on improving endothelial function in HF patients.
Conclusion Certain dietary interventions and nutritional supplements may provide some benefit to patients with HF.
However, there is no relevant definitive evidence on the impact of nutritional interventions on the prognosis of HF, and more high-quality clinical trials are needed for further in-depth studies.
Overall, even though the TEST drink did not augment BW, V(O2)peak, or TTE beyond carbohydrates alone, it did improve body composition (%fat and FFM) within the first 3-6 weeks of supplementation, which may be helpful for practitioners to understand how carbohydrate-protein recovery drinks can and cannot improve performance in their athletes.
Cramer JT et al. · Journal of strength and conditioning research (2012)
Thirty-two men (age, mean ± SD = 23 ± 3 years) performed tests for aerobic capacity (V(O2)peak), time to exhaustion (TTE) at 90% V(O2)peak, and percent body fat (%fat), and fat-free mass (FFM).
Cycle ergometry training was performed at 70% V(O2)peak for 1 hours per day, 5 days per week for 8 weeks.
Percent decreases in %fat from PRE to MID3 and percent increases in FFM from PRE to MID3 and MID6 were greater (p ≤ 0.05) for TEST than CON.
Ribose demonstrated a beneficial trend in lower MDA and reduced glutathione levels during hypoxic stress.
Seifert JG et al. · Journal of medicinal food (2009)
Seven healthy volunteers cycled at their lactate threshold for 25 minutes while inhaling 16% O(2) with a subsequent 60-minute resting period at room air.
Subjects ingested either placebo or 7 g of ribose in 250 mL of water before and after the exercise session.
Urinary malondialdehyde (MDA) and plasma reduced glutathione levels increased significantly during placebo ingestion (0.2 +/- 0.03 nM/mg and 0.26 +/- 0.29 microM, respectively) but were lower with ribose supplementation (0.04 +/- 0.03 nM/mg and 0.38 +/- 0.29 microM, respectively; P < .05).

Because plasma branched-chain amino acid levels are decreased by mental fatigue, these results suggest that administration of caffeine improved task performance through the enhancement of central nervous system activity without increasing the sensation of fatigue.
Ataka S et al. · Nutrition (Burbank, Los Angeles County, Calif.) (2008)
Because plasma branched-chain amino acid levels are decreased by mental fatigue, these results suggest that administration of caffeine improved task performance through the enhancement of central nervous system activity without increasing the sensation of fatigue.
However, further decreases in branched-chain amino acid levels indicate that caffeine might promote deeper fatigue than placebo.
Unfortunately, research subsequent to our study design has shown that D-ribose dosing higher than we used is needed to see a clinical effect and therefore no conclusions can be made from this study as to the efficacy of D-ribose.
