Product Overview

  • Science-Based Nutrition
  • Dietary Supplement
  • BioEnergy Ribose
  • Supports Healthy Energy Levels in Heart and Muscle Tissue
  • Maintains Normal Heart Function
  • Decreases Free Radical Formation During Exercise
  • Vegan

Ribose is an essential pentose (5-carbon) sugar utilized by the body to synthesize DNA, RNA and produce energy. Ribose is a fundamental building block of adenosine triphosphate (ATP-the substance in which the body stores intracellular energy), the preferential source of energy for skeletal muscle and heart tissue. Studies have shown that ribose supplementation can enhance cardiac energy levels and support cardiovascular metabolism. Further studies suggest ribose plays a role in supporting energy recovery after exercise. Exercise increases free radical production in muscle tissue. Ribose may strengthen and support the body's crucial antioxidant defenses.

Research suggest that optimal heart function requires a consistent supply of essential cofactor nutrients including CoQ10, D-ribose, L-carnitine and Magnesium. Consider these other high quality Doctor's Best products in combination with Best D-Ribose for enhanced cardiovascular support: High Absorption CoQ10, High Absorption Magnesium, Best L-Carnitine Fumarate

Continued use is necessary to maintain the benefits of Best D-Ribose featuring BioEnergy Ribose.

Absolutely Works!

Posted by Reviewer1132904 on Aug 07, 2008

This, along with the Energy Revitatlization System from Enzamatic Therapy, has made a dramatic difference in the way I feel. After being diagnosed with Chronic Fatigue and Fibromyalgia last year, no prescription the doctor gave me helped me like these 2 products. I consider them to be a miracle.

Wonderful for energy

Posted by Reviewer1782385 on Jun 14, 2007

I have CFS and this product has really helped with my energy level. I still have bad days but even those are not as bad as they were before taking D-Ribose. I take three scoops a day. You may need to take the whole container before you feel any results.

Fibromyalgia LIFESAVER!

Posted by Reviewer1798622 on Jul 13, 2009

I am a mom of two beautiful daughter and have been married for almost thirteen years! My Fibromyalgia symtoms had been ruining my lifestyle for a few years when I was introduced to Vitamin D3 & Ribose. The D3 helped me to be able to effectively manage many of my symptoms. Yet, the everyday soreness and stiffness I experienced was overwhelming at times. I felt like a 30 Y/O in a 50 Y/O body. So trying to do the average things moms and wives do was difficult. I read From Fatigue to Fantastic and learned about Ribose being used with people who suffered from auto immune problems, instead of just athlete who needed to recover faster. I gave it a try. Three scoops a day for two weeks, then two scoops a day after that. I was convinced after the first week! I know had energy to last me past putting my kids to bed. I could clean my house on a regular schedule, and enjoy everyday life again. I would recommend this to ANYONE who needs energy and relief from muscle fatigue. My only caution would be to check with your Dr. if you have any problems processing sugar. Even though our bodies make Ribose, some, like my mom, have problems adding the Ribose to their diet. And thanks to iHerb.com I can afford to keep getting the benifits I need!!!!!

Peggy Carraway Murray KY

Posted by Reviewer3090815 on Jul 28, 2008

This is a great buy. I had been buying in my local health food store, but will buy from iHerb from now on. Not only does Doctor's best D Ribose mix better but you only need to use one scoop. I use it for my fibromyalgia and WOW what a difference. I was out of it for about a week and my body began to ache and stiffen up. I have been using Ribose for about nine months--no pain and no pain pills.
