Source material country of origin? And processing/chemical reduction country? No seller answers; probably in China?

You would be correct, made in China. That's why I would never order it again.

I haven’t been able to get a reply from the contact us section on the micro ingredients website. is this product quality tested? is it usda organic?

We have been using this product for years and do not see any problems with it. D-Ribose is a trade name ver 20 yrs or so now.

The info shows this is in a bag protected from uv rays. Is that important? I transferred it to a clear jar for easier use due to neuralgia- ?

Honestly, I don't know how important it is. I have a clear plastic 1-cup tub I put it in and keep the rest in the bag, but I store both in a closed cabinet. I don't see how UV can affect it as long as it is not in a window, so as long as you don't notice a change in the amount of pain relief, it will be fine.

i am not familiar with this brand. How do i know it is pure since these products are not FDA regulated?

I found this product to be rated #1 after research review. I have used this product before and find it very effective in getting oxygen to my muscles, especially my heart muscles.
