Ribose pill and athletic performance - supplementation information
For energy and muscle, heart tissue

Ribose is a carbohydrate, or sugar, used by all living cells and is an essential component in our body’s energy production.
Ribose has many important roles in physiology. Among them, ribose is a necessary substrate for synthesis of nucleotides, and it is part of the building blocks that form DNA and RNA molecules. The claim made is that ribose enhances athletic performance. As of March 2009, we have not seen any data to support that ribose is a beneficial nutrient for athletes. We will update this page as more studies become available.  For more up to date ribose research.

 D Ribose, Source Naturals

* Fruit Flavored
* Dietary Supplement

During strenuous exercise, large amounts of ATP, the body's primary energy-carrying molecule, can be depleted in heart and skeletal muscle cells. D-Ribose is a simple sugar that is used by the body to synthesize nucleotides, ATP, nucleic acids, and glycogen.*

Benefits
Patients with chronic fatigue syndrome given D-ribose at a dose of 5 grams three times a day for a total of 280 grams showed improvement in energy levels. This regimen also helped in those with fibromyalgia..
Oral ribose supplementation with 4 g doses four times a day does not help postexercise muscle ATP recovery and maximal intermittent exercise performance.

Ribose may help some individuals with chronic fatigue syndrome or those with fibromyalgia. Ribose does not help patients with McCardle's disease.In patients with coronary artery disease, administration of ribose by mouth for 3 days improved the heart's tolerance to ischemia. There is no research published in peer-reviewed journals that shows ribose improves athletic performance.

Ribose and athletic performance
Oral ribose supplementation with 4-g doses four times a day does not help postexercise muscle ATP recovery and maximal intermittent exercise performance. There have been claims that ribose supplements increase ATP levels and improve athletic performance. Most studies show lack of effectiveness of ribose as an ergogenic aid at high doses.
There is no research published in peer-reviewed journals that shows ribose improves athletic performance.

Ribose versus dextrose supplementation, association with rowing performance: a double-blind study.
Clin J Sport Med. 2006 Jan;16(1):68-71. Dunne L, Worley S, Macknin M. Sports Medicine Center, Ohio State University, Columbus, OH, USA.
We compared the effects of ribose versus dextrose on rowing performance. We studied the effects of ribose versus dextrose supplementation (10 g each in 8 oz water) for 8 weeks before and after practice and 2000-m time trials. In the time trials, the dextrose group showed significantly more improvement at 8 weeks than the ribose group. We doubt ribose impaired, and hypothesize dextrose enhanced, rowing performance. Further research is needed to define what role, if any, dextrose and ribose play as athletic supplements.

Effects of ribose as an ergogenic aid.
J Strength Cond Res. 2006 Aug;20(3):519-22. Peveler WW, Bishop PA, Whitehorn EJ. Department of Health and Kinesiology, Mississippi University for Women, Columbus, MS 39701, USA.
There have been claims that ribose supplements increase ATP levels and improve performance. Other studies have provided mixed results on the effectiveness of ribose as an ergogenic aid at high doses. None of these studies have compared the impact of the recommended dose of ribose on athletes and nonathletes under exercise conditions that are most conducive for effectiveness. The purpose of this study was to evaluate the effectiveness of ribose as an ergogenic aid at the dose recommended for supplements currently on the market during an exercise trial to maximize its efficacy. Male subjects (n = 11) performed 2 trials 1 week apart. Each trial consisted of three 30-second Wingate tests with a 2-minute recovery between each test. Trials were counterbalanced, with 1 trial being performed with 625 mg of ribose and the other with a placebo. Peak power, mean power, and percent decrease in power were recorded during each Wingate test. Repeated-measures analysis of variance (p > 0.05) found no significant differences between ribose and placebo. These results suggest that ribose had no effect on performance when taken orally, at the dose suggested by the distributor.

Effect of ribose supplementation on resynthesis of adenine nucleotides after intense intermittent training in humans.
Hellsten Y. Institute for Excersize and Sport Science, DK-2100 Copenhagen, Denmark. yhellsten@aki.ku.dk
Am J Physiol Regul Integr Comp Physiol. 2004 Jan;286(1):R182-8.
The effect of oral ribose supplementation on the resynthesis of adenine nucleotides and performance after 1 wk of intense intermittent exercise was examined. Eight subjects performed a random double-blind crossover design. The results support the hypothesis that the availability of ribose in the muscle is a limiting factor for the rate of resynthesis of ATP. Furthermore, the reduction in muscle ATP observed after intense training does not appear to be limiting for high-intensity exercise performance.

Effects of oral D-ribose supplementation on anaerobic capacity and selected metabolic markers in healthy males.
Kreider RB,. Baylor University, Waco, TX 76798-7313, USA. Int J Sport Nutr Exerc Metab. 2003 Mar;13(1):76-86.
Oral D-ribose supplementation has been reported to increase adenine nucleotide synthesis and exercise capacity in certain clinical populations. Theoretically, increasing adenine nucleotide availability may enhance high intensity exercise capacity. This study evaluated the potential ergogenic value of D-ribose supplementation on repetitive high-intensity exercise capacity in 19 trained males. Subjects were familiarized to the testing protocol and performed two practice-testing trials before pre-supplementation testing. Each test involved warming up for 5 min on a cycle ergometer and then performing two 30-s Wingate anaerobic sprint tests on a computerized cycle ergometer separated by 3 min of rest recovery. In the pre- and post-supplementation trials, blood samples were obtained at rest, immediately following the first and second sprints, and following 5 min of recovery from exercise. Subjects were then matched according to body mass and anaerobic capacity and assigned to ingest, in a randomized and double blind manner, capsules containing either 5 g of a dextrose placebo (P) or D-ribose (R) twice daily (10 g/d) for 5 d. Subjects then performed post-supplementation tests on the 6th day. Data were analyzed by ANOVA for repeated measures. Results revealed a significant interaction (p =.04) in total work output. Post hoc analysis revealed that work significantly declined during the second post-supplementation sprint in the P group while being maintained in the R group. No significant interactions were observed in peak power, average power, torque, fatigue index, lactate, ammonia, glucose, or uric acid. Results indicate that oral ribose supplementation (10 g/d for 5 d) does not affect anaerobic exercise capacity or metabolic markers in trained subjects as evaluated in this study.


Ribose for chronic fatigue
Ribose may help some individuals with chronic fatigue syndrome or those with fibromyalgia.

Ribose for heart disease
In patients with coronary artery disease, administration of ribose by mouth for 3 days improves cardiac tolerance to ischemia.

Ribose supplementation and mental fatigue
Effects of oral administration of caffeine and D-ribose on mental fatigue.
Nutrition. 2008 March.
We examined the effects of administering two different candidate antifatigue substances, caffeine and D-ribose, on mental fatigue.  In a double-blinded, placebo-controlled, three-way crossover design, 17 healthy volunteers were randomized to oral caffeine (200 mg/d), D-ribose (2000 mg/d), or placebo for 8 d. As fatigue-inducing mental tasks, subjects performed a 30-min Uchida-Kraepelin psychodiagnostic test and a 30-min advanced trail-making test on four occasions. Supplementation with D-ribose had no benefit or effect.
   Comments: D ribose supplementation at 2 grams was not effective for mental fatigue. Perhaps higher dosage may have an effect.


Ribose supplementation questions
Q. My dad is 80 and has had a kidney removed due to a benign tumor. His energy level is sometimes very low as a result. I'm thinking ribose supplementation may help that. Is there any contraindication in kidney patients I should be aware of, using ribose pills?
   A. We have not seen studies regarding ribose supplementation and its effect on kidney function.

Q. I am taking ribose for heart damage from a stroke. Do you think creatine would be better?
   A. We have no way of predicting whether creatine or ribose would be helpful for your particular condition.

Q. I took ribose supplement and could tell an improvement in cardiac irritability in 15 minutes after 4.5 grams D-Ribose. Ectopic beats ceased after 30 minutes, and no further episodes of SVT supra ventricular tachycardia (Have been having episodic SVT bursts, and A. Fib. for past ten years lasting 4-12 hours per episode). Ran out of D-Ribose for 36 hours until shipment came in today and ectopic beats resumed 30 hours after last dose. Again ectopics ceased 30 minutes after resuming D-Ribose.

Q. I'm trying the product Ribose Muscle Edge. My mom heard about it on the Oprah show with Dr. Oz, who spoke highly of this ribose Supplement. I'm trying it for my bad bad Fibromyalgia and CFS. So I went and bought the ribose powder 100 grams and it says 1-3 scoops before of after work out. My work out is walking.
My question is. o I put it in water? Juice? Over something. I have looked and looked for how to take it and have found nothing.
   A. We are not familiar with Ribose Muscle Edge ribose supplement in particular, but ribose powder in general can be mixed with juice.
