Description
A naturally occurring five-carbon sugar central to the structure of ATP, RNA, and several coenzymes. Used in sports and cardiovascular supplements to support ATP regeneration after intense exertion or ischemic stress.
White to off-white crystalline powder with a mildly sweet taste, roughly 80 percent the sweetness of sucrose. Highly water-soluble.
We supply food-grade and pharmaceutical-grade D-Ribose from manufacturers in China holding ISO, Halal, Kosher and other certifications relevant to the product and production. Produced by microbial fermentation of glucose.
Common market grades include standard food-grade D-Ribose 98%, pharmaceutical-grade 99% USP, and pre-blended formats with electrolytes or creatine for sports use.
Bulk and reduced-MOQ shipments. Batch-level COA covering assay, optical rotation, heavy metals, and microbiology.
Introduction
D-Ribose is the pentose sugar component of ATP, ADP, AMP, RNA, NAD, and FAD. It is synthesized in the body from glucose via the pentose phosphate pathway, but the conversion is slow relative to demand during repeated high-intensity exercise or ischemic recovery.
Clinical use in cardiology emerged in the 1990s for congestive heart failure and post-ischemic myocardial recovery, where oral D-ribose was shown to accelerate restoration of intracellular adenine nucleotide pools. Sports-nutrition applications followed in the 2000s.
Commercial production is by fermentation of glucose using engineered Bacillus subtilis strains, yielding food-grade and pharmaceutical-grade material with consistent optical purity and low impurity profile.
Typical adult dosing is 3 grams to 5 grams per dose, taken one to three times daily depending on application. The compound is well tolerated, with mild gastrointestinal effects reported only at single doses above 10 grams.
Where it is used
- Cardiovascular-support supplements for congestive heart failure and angina
- Sports recovery and endurance products
- Chronic fatigue syndrome and fibromyalgia management protocols
- Pre-workout and intra-workout energy formulations
- Functional beverages targeting energy and recovery
- Co-formulation with creatine, L-carnitine, and CoQ10
- Equine performance supplements
- Medical nutrition products for mitochondrial myopathy
