核糖是一种天然存在于体内的糖。由葡萄糖（血糖）制成，核糖是三磷酸腺苷（或ATP）的关键成分。a molecule involved in storing and releasing energy) and ribonucleic acid (or RNA,a molecule involved in protein synthesis and other cell activities).有时被称为D-核糖，ribose is also available in supplement form.
Some alternative medicine proponents claim that ribose supplements help with a variety of health problems,包括慢性疲劳综合症和fibromyalgia.In addition,some people take ribose supplements in an effort to increase energy and enhance athletic performance.
To date,there is limited scientific evidence to support the use of ribose supplements for any health condition.Here's a look at some key findings from the available research on ribose supplements:
1) Fibromyalgia and Chronic Fatigue Syndrome
发表在替代与补充医学杂志in 2006 studied 41 patients with fibromyalgia and/or chronic fatigue syndrome who were given ribose supplements.By the study's end,66 percent of the patients had experienced significant improvement in symptoms (such as lack of energy,difficulty sleeping,andpain）
Bothfibromyalgiaand chronic fatigue syndrome are marked by impaired energy metabolism.The study's authors suggest that ribose may help treat fibromyalgia and chronic fatigue syndrome by increasing the production of energy in the heart and muscles.然而，more research is needed.
Although ribose supplements are widely touted as a natural remedy for enhancing exercise endurance,two small studies (one published in theInternational Journal of Sport Nutrition and Exercise Metabolism2003，另一篇发表在Journal of Applied Physiologyin 2001) suggest that ribose supplements may have no effect on athletic performance.
Ribose supplements may be of some benefit to heart failure patients,suggests a small study published in theEuropean Journal of Heart Failure2003。For three weeks,15例充血性心力衰竭患者接受核糖补充剂或安慰剂治疗。After taking a one-week break,这些病人在接下来的三周内被转移到替代治疗。研究结果表明，核糖类补充剂能提高生活质量，改善某些心功能指标。
It's important to keep in mind that supplements haven't been tested for安全膳食补充剂基本上是不受管制的。In some cases, the product may deliver doses that differ from the specified amount for each herb.In other cases,the product may be contaminated with other substances such as metals. Also,the safety of supplements in pregnant women,nursing mothers,children,而那些有疾病或正在服药的人还没有确定。
Due to the limited research,任何情况下推荐核糖补充剂都为时过早。重要的是要注意自我治疗和避免或延迟标准护理可能会产生严重后果。If you're considering the use of ribose supplements in the treatment of any chronic condition,talk to your doctor before starting your supplement regimen.
