I take d-ribose capsules daily. Usually about 1200 mg. it does give me some energy and I can tell on the days I don't take it.
I've found even on bad days it'll give me energy and have to be careful not to overdo it and end up feeling worse.
I definitely recommend it. It does help me.

I was recommended Ribose but was worried about weight gain since it's a sugar. Did you have any issues on it?

Amazon.co.uk

I haven't heard of that before. Where do you get this from???

I am also looking to try ribhose and would be interested of any views or opinions on it
