Good product but not for me
By Jodi-Hummingbird
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. It was obviously a physical effect form the ribose that I had to wait to wear off.It felt like I had taken a huge dose of slow-release caffeine (or an illegal stimulant), but one which had a cumulative effect and built day by day. Fake energy I guess, nothing at all like the real thing. I stopped taking the ribose the next day. This overstimulated effect then took 2 -3 days to subside. It wasn't pleasant. I wonder if it causes a big rush of adrenaline like taking lots of caffeine does. I am not at all sure if it does or not but it felt a lot like that, at least, and just as unhealthy.I really wanted to make sure it wasn't just a coincidence though and an effect caused by some other variable. I didn't want to miss out on something potentially helpful unless it was really necessary. So 4 times I tried the ribose again in the same way, over 4 months, and each time I got the same effect. It was definitely the ribose. For me ribose pushed my body into getting hyped up and writing cheques that it couldn't cash.Ribose is quite well known to be not well tolerated by some people. That is why I chose to try this supplement last, years after taking the far safer and better tolerated carnitine, ubiquinol and magnesium.I have no criticism of this brand though. I buy lots of Jarrow products and it is a good brand and no doubt this is a good product, for those that it works well for. This supplement really helps some people with serious heart conditions I know (from reading books by the above authors), and doses of 5 - 15 grams are commonly used and have a good effect, but I am just not one of them. Maybe it is just biochemical individuality.I'd be curious to know if others have had the same problems with ribose that I have, if anyone has the time.For anyone wanting to try this I'd say make sure you take it for 3 - 4 weeks and at a least at a dose of 5 grams a day before buying a second bottle as any negative effects may take this long and this high of a dose to appear.

Try it for 3 weeks!
By Robert Nerden
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.

worked for my fibromyalgia
By joivie
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.
