Ribose

Ribose is a carbohydrate with the formula C5H10O5, that exists in two forms: D-ribose, which occurs in nature and L-ribose, which is the mirror image of D-ribose and does not occur in nature.

D-ribose is a building block used by the cells in one of the chemical pathways that makes the energy molecule, ATP.

D-ribose comes in powder form, tastes sweet, and can used as a sugar substitute in drinks or on cereal.

Use in ME/CFS and FM
It is used as a supplement for help boost muscle energy, such as for athletes and people with ME/CFS, Fibromyalgia, and coronary artery disease. The theory is that if one supplies the body with the precursors to ATP, then it will be easier for the body to make ATP.

Evidence
A small study of 41 patients by Jacob Teitelbaum resulted in: "Approximately 66% of patients experienced significant improvement while on D-ribose [at a dose of 5 g, three times a day], with an average increase in energy on the VAS [visual analog scale categories: energy; sleep; mental clarity; and pain intensity] of 45% and an average improvement in overall well-being of 30% (p < 0.0001)." The study authors concluded that "D-ribose significantly reduced clinical symptoms in patients suffering from fibromyalgia and chronic fatigue syndrome".

Risks
D-Ribose is linked to memory loss, anxiety, & Aβ-like deposits associated with Alzheimer’s in Mice
