D-ribose is a five-sided sugar (pentose) that is the rate-limiting step in energy production. It is also important for synthesizing nucleic acids (DNA, RNA). Though d-ribose supplements do not appear to improve strength or athletic performance per se, they do appear to improve recovery. This is especially true in individuals with chronic Lyme disease or fibromyalgia. D-ribose can also reduce post-exertional pain.
Suggested Dosage: 1 gram (1000 mg) two to three times daily. D-ribose will add sweetness to your smoothies.
Side effects: None expected. Considered a functional food.
