Interesting study - but it's not surprising to me that diabetics would have abnormally high levels of d-ribose, as they do with other sugars. So perhaps diabetics should avoid d-ribose as with other sugars. And it is probably a good idea to see if there are any other studies on non-diabetics and problems with d-ribose (which I hope is not the case!)
There are several other threads on, or discussing, d-ribose, for example
this one. Adverse effects are reported.
Here is another thread.[/quote]
Okay, I didn't realize there was so much controversy re d-ribose. I didn't realize some reacted so badly to it, but as you can see from your links it does help many people a lot. But it's good to know the other side of the coin. For me, it's been one of the few things that has noticeably increased my energy and that has been worth the money to take. But I can't take certain things other people do - we all react differently. Some people increased their energy a lot by high-dose thiamine and this was not good for me at all. I pay close attention to how my body reacts when I introduce something new and that seems to be one of the best ways to determine if something is good for me or not. I know it's not scientific, but it works - I'm better off than I was 5 years ago and 10 years ago and 15 years ago and so on ..
I've been taking CoQ10 for a long time with no noticeable effect but a test showed my levels were low so I take it.
Several months ago I tried cutting out all the mito supplements I've been taking for many years, wondering if they were continuing to help as I seem to have reached a plateau. And I found out in short order that I did indeed need them - I felt worse without them - so added them back in.
Any ways, thanks for the info - it's always better to have more information --
