What is Doctor’s Best D-Ribose featuring BioEnergy Ribose? Doctor’s Best D-Ribose featuring BioEnergy Ribose supports energy production in the heart and muscles and promotes muscle recovery following exercise. D-ribose forms the structural core of ATP. ATP is the energy source for our muscles during physical activity and the primary source of energy for our heart. BioEnergy Ribose is a patented ingredient proven to restore and sustain energy. Best D-Ribose featuring BioEnergy Ribose is available in powder, capsule and chewable wafer forms. How does it work? Human cells normally can produce their own ribose to contribute to ATP production, but stressful states can interfere with the supply of ribose. In the body’s skeletal (“voluntary”) muscles, ribose can enhance the rate of ATP replacement after its depletion by intense exercise. The repetitive muscular contractions during bouts of strenuous exercise can temporarily lower ATP in skeletal muscle. The muscle’s transition from a resting state to one of high intensity exercise can increase its ATP use by several hundred-fold, so that ATP levels can plunge to 60-70% of resting values. If the individual regularly performs intense exercise, ATP in the resting skeletal muscle may decrease up to 20%, in part due to a loss of ribose and other high-energy building blocks from the muscle fibers. Heart muscle is not well equipped with enzymes that readily facilitate production of high-energy molecules so supplementing with ribose has proven to promote the heart’s energy metabolism and its functional performance. Why should I take Doctor’s Best ChewableD-Ribose featuring BioEnergy Ribose? Every cell in our body makes ribose to contribute to ATP production. Ribose is used in the production of the chief energy compound ATP (Adenosine Triphosphate). ATP is like fuel for our cells and provides us with the energy to run our bodies. If you’re doing something strenuous that requires a lot of exertion, you’ll use a lot of ATP. And as you wait for your body to create more ATP, you will be in a recovery mode and may feel sluggish, stiff or sore even after you’ve rested for a while. When you supplement with Best D-Ribose featuring BioEnergy Ribose, your body will be able to quickly rebuild the depleted ATP and you’ll recover from exercise much faster.
