D-Ribose- A very promising and safe new fibromyalgia/CFS treatment.
Information and an invitation to be part of a study (very simple to do)
Dear Readers,
This is in follow up to the e-mail newsletter below. We got 170 applicants for the 150 spots in the study the first day and then closed applications. As it turns out, ~ ½ had significant osteoarthritis or other problems which makes one not eligible, so we have room for ~ 70 more applicants for the ribose study. If you’d like to be in the study,and
DO NOT HAVE SIGNIFICANT ARTHRITIS ,the study is open to anyone who:
1-Has been diagnosed with Fibromyalgia by a physician and is at least 18 years old
2-Does not have severe medication/chemical/supplement sensitivities
3-Does not have diabetes or other severe illnesses (e.g.-significant arthritis [if its mild arthritis or only fibromyalgia pain, you can answer "no" to the arthritis question], cancer, hepatitis, congestive heart failure) and is not pregnant or breast feeding.
4-Lives in the United States (sorry Jenny)
D-Ribose (Corvalen) is a safe nutrient that works by directly increasing energy production. In our last study, 2/3 of CFS/Fibromyalgia patients improved after ~ 2 weeks. It is natural, quite safe, tastes good (sweet like sugar but healthy) and very low in side effects. Rarely, it leaves people over-energized/anxious. If so, you can simply lower the dose or take it with food.
This study will be a “Gold Standard” placebo controlled study. This means that ½ of you will get the real Ribose, and the other ½ an inert placebo with no effect. Neither the investigators nor participants will know who is getting the real thing vs. placebo till you finish the study. After taking 1 month’s worth of Ribose and returning your questionnaire and what remains in your container however, we will send you a free (definitely real) container as our way of saying thank you for participating. You can do the entire study by mail and continue any treatments you are currently on. However, we do ask that you not change anything you are taking during the month you’ll be on the study.
To be part of the study, all you need to do is:
1- Take 1 scoop of ribose 3 x day. It can be mixed with food, water, other beverages, etc. It is normal to occasionally miss a dose, so do not worry about that being a problem.
2-Fill out a simple questionnaire on the date you start the treatment and again in a month when you are taking the last dose.
3-Stay on your current treatment(s), if any, and do not add any other new treatments while you are on the Ribose.
4-After a month on the Ribose, mail the questionnaire and the ribose containers in the SASE envelope we supply (even if empty). We’ll then send a free container.
5-If you have any questions, feel free to e-mail Angie at claims@endfatigue.com. The first people who return the form and fit the above criteria will be entered in the study. You can E-mail the form below to claims@endfatigue.com or fax it to 410-266-6104. Thank you for helping

Dr Teitelbaum ran a pilot study on d-ribose supplements for CFS.(abstract below). They are now running a larger double blind study.
How do VitB1 and d-ribose fit in again.. somewhere in those metabolism cycles??
ABSTRACT
Objectives
Fibromyalgia and Chronic Fatigue Syndrome are debilitating syndromes which are often associated with impaired cellular energy metabolism. As D-ribose has been shown to increase cellular energy synthesis in heart and skeletal muscle, this pilot study was done to evaluate if D-ribose could improve symptoms in Fibromyalgia and/or Chronic Fatigue Syndrome patients.
Design
Forty-one (41) patients with a diagnosis of Fibromyalgia and/or Chronic Fatigue Syndrome were given D-ribose, a naturally occurring pentose carbohydrate, at a dose of 5-g TID for a total of 280 grams. All patients completed questionnaires containing a Visual Analog Scale and global assessment pre- and post- D-ribose administration.
Results
D-Ribose, which was well tolerated, resulted in a significant improvement in all 5 Visual Analog Scale categories: energy, sleep, mental clarity, pain intensity, and well being, as well as an improvement in patients’ global assessment. Approximately 66 % of the patients experienced significant improvement while on D-ribose, with an average increase in energy on the Visual Analog Scale of 45% and an average improvement in overall well being of 30%.
Conclusions
D-Ribose significantly improved clinical symptoms in patients suffering from fibromyalgia and chronic fatigue syndrome.

Synthesis of NADPH and Pentoses
TDP is coenzyme for transketolase
key enzyme in HMS (Phase 3)
“reshuffling” of carbon atoms
achieved by transfer of two-or three-carbon units to appropriate acceptor molecules
ie, carbons 1 and 2 of D-xylulose-5-phosphate are transferred by Transketolase (TDP) to an acceptor unit which is D-ribose-5-phosphate
....
so when I took d-ribose it felt like it built up after a while and then made me worse ..so I stopped it..
next idea was I was low on thiamin.. perhaps it had all been used up by this d-ribose?
I need to look at thiamin in more detail.. with diagrams etc to understand this
Then again, I had shingles last year which can be alleviated with taking thiamin i've read, so could be a sign of thiamin deficiency.----------------
THis
seems to be saying that blocking transketolase (which uses b1 has a cofactor)then more d-ribose is produced.. now have to work out why.. maybe as d-ribose doesnt get consumed at same time?
also did ya see this??"D-ribose, a five-carbon sugar, is used as a key intermediate for the production of various biomaterials, such as riboflavin and inosine monophosphate"
does this also happen in our bodies?? which may mean d-ribose is needed to make B2 and inositol?.. which may be why I needced to take more riboflavin (b2) and was considering and tried once inositol.then promptly forgot about it the next day.. sigh(maybe as the obne dose of inositol topped me up)
If less d-ribose from increased transketolase (via B1)..maybe.. then maybe less riboflavin and inositol..

The availability of phosphoribosyl-5-pyrophosphate (PRPP) is rate limiting in adenine nucleotide synthesis and salvage pathways required to restore nucleotide pools and rebuild cellular energy stores.20-23 PRPP is formed through a pyrophosphorylation reaction from ribose-5-phosphate that is, in turn, synthesized from glucose via the Pentose Phosphate Pathway (PPP; or Hexose Monophosphate Shunt). The activity of the PPP varies between organs, with those synthesizing fatty acids and sterols being most active. The rate limiting enzymes in the PPP, glucose-6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase, have limited expression in muscle. As such, energy production in muscle via this mechanism is delayed and cannot be relied upon to replenish depressed adenine nucleotide pools during or following a metabolic insult, such as prolonged periods of hypoxia.

RIBOSE in Maintaining Tissue Energy Stasis
Tissue hypoxia leads to a progressive depression of the cellular purine nucleotide pool creating an energy deficit (Figure 2). The adenine nucleotide ATP is the primary energy source of all living cells. In tissues suffering the metabolic stress of hypoxia or ischemia, ATP is broken down and the metabolic machinery to recycle expended energy is disrupted. As such, adenosine diphosphate (ADP) levels accumulate leading to a series of reactions undertaken by the cell to balance ATP/ADP ratios and maintain energy stasis. These reactions ultimately lead to increased concentrations of adenosine monophosphate (AMP) in the cell. In a further effort to control energy balance, heart cells catabolize AMP, in reactions catalyzed by 5'-nucleotidase and AMP deaminase, to form inosine, hypoxanthine and adenine. These catabolic end products are washed out of the cell netting a reduction in the total pool of adenine nucleotides available to the tissue and lowering its phosphorylation potential (Figure 2). Up to 90% of these catabolites can be biochemically salvaged and recycled.20-22
The availability of phosphoribosyl-5-pyrophosphate (PRPP) is rate limiting in adenine nucleotide synthesis and salvage pathways required to restore nucleotide pools and rebuild cellular energy stores.20-23 PRPP is formed through a pyrophosphorylation reaction from ribose-5-phosphate that is, in turn, synthesized from glucose via the Pentose Phosphate Pathway (PPP; or Hexose Monophosphate Shunt). The activity of the PPP varies between organs, with those synthesizing fatty acids and sterols being most active. The rate limiting enzymes in the PPP, glucose-6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase, have limited expression in muscle. As such, energy production in muscle via this mechanism is delayed and cannot be relied upon to replenish depressed adenine nucleotide pools during or following a metabolic insult, such as prolonged periods of hypoxia.
The rate of recovery of depressed energy levels following ischemia and/or hypoxia is important for functional recovery of muscle20,21,23,24, providing adequate levels of AMP and ADP necessary for complete repletion of ATP. Blocking the degradation of adenine nucleotides, or by providing metabolic supplementation to enhance nucleotide recovery via the salvage or de novo pathways are potential solutions to maintaining energy stasis. Exogenous ribose administration provides the metabolic support required to bypass the rate limiting enzymes of the PPP, form PRPP and restore energy stasis in metabolically stressed muscle.20-25
RIBOSE has been extensively studied in both hearts and muscles. Safety data is well accepted, with no noted significant adverse reactions. Experiments on the use of ribose to enhance myocardial and skeletal muscle adenine nucleotide synthesis and salvage have involved both animal and human investigations and the effects of ribose in hearts are not species specific.26 The low activity of glucose-6-phosphate dehydrogenase is in the same order of magnitude in human, rat, guinea pig and dog hearts.
The effect of ribose treatment in myoadenylate deaminase deficiency (AMP deaminase deficiency)27-31 and adenylosuccinase deficiency32,33 has been well documented. Like fibromyalgia, these conditions lead to progressive depletion of cellular energy pools, leading to muscle pain, soreness and stiffness. The beneficial role in energy recovery in these disease conditions with ribose treatment is suggestive of its potential role in energy recovery in fibromyalgia. As in the case of myoadenylate deaminase deficiency, anecdotal reports from fibromyalgia patients indicate a reduction in fatigue, muscle soreness and stiffness associated with the condition. While further research continues, it is apparent that ribose can play a beneficial role as an adjunctive, metabolic treatment for fibromyalgia.

and also
I wonder if B1 works with coQ10 this way too.. I could never take that for too long either?
