Product Description

Size: 100g

Product Profile

Jarrow Formulas Ribose (100% D-ribose) is for athletes and others interested in improved energy, endurance, and recovery.* Ribose is a carbohydrate found in every cell in the body. It is an important component of DNA and RNA, structures that make up our genes. Ribose is also an essential precursor to ATP, the body’s main energy source.* Research since the 1970s has continued to confirm the benefit of this compound for the heart and circulation, and recently for energy metabolism in skeletal muscles.*

Energy Production By The Cells

ATP (adenosine triphosphate) contains ribose, adenine, and three conjoined phosphate groups. Energy transfer involves the linking and unlinking of these phosphate groups. Thus, ATP provides energy when it loses a phosphate group to become ADP (adenosine diphosphate), or when it loses two phosphates to become AMP (adenosine monophosphate). Phosphate groups must be added back to AMP and ADP to replenish ATP. Creatine, another popular supplement for athletes, and the creatine phosphate system help muscles quickly replenish ATP during intense exercise by doing just that.*

Distinguishing Features:

  • Produced via microbial fermentation
  • Bioenergy ribose
Ribose Links To Energy

Under extreme stress, or in certain disease states, phosphate groups do not reattach to form ATP, and ADP is further broken down into AMP. The build-up of AMP in cells is not a stable condition, so some AMP is removed, resulting in the loss of adenine and ribose. Loss of these components in cells decreases energy storage capacity and makes it harder for the body to store and transfer energy. Cells cannot absorb ATP from blood, so each must make its own ATP. At any one time, enough ATP is stored in the body for about 10 seconds of all-out exertion – so it is imperative to keep the ADP-to-ATP energy cycle flowing smoothly. The more active the muscle, the more ATP it uses. During intense exertion, skeletal muscles quickly exhaust their ATP stores; heart muscle is particularly vulnerable to ATP shortages. As an ATP precursor, active muscles can therefore benefit from ribose supplementation.*

Ribose Improves Muscle Energy And Recovery

It should be noted that ribose is not readily available in amounts near recommended quantities from any food source. The body must make ribose from glucose through a series of complicated and energy-intensive steps. Unfortunately, this process is quite slow and may actually require days to complete. Supplemental ribose, in contrast, is immediately available to the body.* The body uses ribose energetically in three ways:

  1. Ribose can be used to produce glucose and glycogen (the storage form of carbohydrate energy). While offering the energy benefits of sugars, ribose does not affect blood sugar levels.*
  2. When oxygen is available, ribose can be converted into pyruvate, another energy source.*
  3. Most importantly, ribose is necessary for ATP production. With ribose, cells can recover rapidly from intense exertion.*

Research has shown that intense exercise causes significant adenosine phosphate decreases in skeletal muscle. These energy carriers were not fully replaced even after 72 hours of rest. This may be an important consideration in overexertion and in over-training. Research presented at the American College of Sports Medicine meeting in 1999 indicates that ribose supplemention may greatly reduce recovery time after intense exertion.* Indeed, ribose is the immediate precursor to PRPP (5-phosphoribosyl-1-pyrophosphate), which is the rate-limiting factor in ATP synthesis. For athletes, this is of major importance. The synthesis of the adenine/ribose component of ATP is 3-6 times faster with ribose supplementation.* Ribose is one of the necessary building blocks for the formation of ATP, the “universal” energy molecule in the body.* Physical stress can deplete ATP stores in cardiac and skeletal muscles. As the rate-limiting substrate in the synthesis of nucleotides, including ATP, ribose plays a vital role in replenishing ATP, thus, enhancing energy production, improving muscle recovery, and thus Muscle Edge.*

I started taking ribose early 2012 as part of Dr Stephen Sinatra's 'awesome foursome of cardiovascular health' (along with magnesium, carnitine and CoQ10) and because it was recommended by Dr Sherry Rogers for those with poor mitochondrial function.

When I take CoQ10 (especially the reduced ubiquinol form), carnitine and magnesium it makes me feel more well. Less ill and like my body is struggling less with basic functions. I sleep better and longer, and my heartbeat feels stronger and less flutterly and weak, it takes more to bring me to a point of overexertion and if I do still seriously overexert, these things very much stop the relapse from being as severe and scary. (I have severe cardiac problems and neurological problems partly caused by poor mitochondrial function.)

Even at higher doses of these things (plus B complex and vitamin C), they never feel anything like taking a stimulant would and never keep me awake or make me agitated. But I have found ribose to be quite different.

I started ribose at a dose of 1 - 2 grams a day for about 2 weeks. I didn't feel much at this dose so I went slowly up to a 5 gram a day dose (taken in two doses of 2.5 grams). After a few days I began to feel strange and a bit 'unrestful' and anxious, but I wasn't sure if it was the ribose causing it so I kept going. The next day or two I knew something was really off and wrong. I couldn't sleep until 5 in the morning, found it really hard to get in a restful state of mind and spent hours so physically tense that I was a hairs breadth away from grinding my teeth - something I have never done before or since. The pressure in my jaw was just huge and if I were well enough I'd probably have paced the room too. No amount of meditation helped with the sleeping or the jaw tensing either.

First thing you can't beat the price anywhere and free shipping!
I know that this product is mainly target for people with chronic fatigue or neuropathy. I don't have any such medical conditions. I have been using this product for a couple of months and the the most noticeable effect is recovery from strenuous activity. For example the first leaf clean up of the fall is always a killer. The next day my neck shoulders and lower back are stiff sore and just ache, taking about a week to go away. This year there was a snow storm the day after so I had to shovel after spending a day clean my yard. That said I was just a little sore the next day and had no problem shoveling ! Ribose taste a little sweet if added to water mixes smooth absolutely zero grittiness.

I have much less severe muscle pain after using this for a few days. It comes back if I stop using the product. Very sweet, like straight sugar.

Diabetes and arthritic conditions (and getting older) render me more susceptible to exhaustion and pain, particularly after exercise. This product, as recommended in "The Sinatra Solution," helps me feel like exercising, and relieves some of the achiness and exhaustion I often feel subsequently.

I read Dr. Jacob Teitlebaums's book "From Fatiqued to Fantastic" and decided that I would follow his protocols....D-Ribose is recommended in his book. I didn't have anything lose but a few dollars.....as it turns out.....the money was not lost at all! The cost is worth it for it has given me more energy and quicker recovery from working than anything I've ever tried. Keep in mind, as with most treatments, it takes time, and keeping up with the protocols for it to work its best! I am so very glad I found D-Ribose on Amazon!

Since I suffer from excess fatigue, I find this supplement to be making a real difference in my life. I find that just one scoop gives me a a nice dose of energy without making me feel wired like coffee does. I have now quit drinking coffee because this is the healthier alternative for me. I give D-Ribose powder five stars!

I would buy this again, just know I need to use two scoops. So the number of doses stated on the carton is incorrect for me.

I bought this because I could do it on auto order. But when I got it and compared it to the other brand I usually order, the dose required was twice the other amount, making this contained have 1/2 the other for the same price. Physical effect was good - no problem there - just the cost.
