Not sure
I purchased this based on its contents and the fact that I believe it was processed in the USA.  I’ve only been using this product for a little over 2 weeks and have noticed nothing, perhaps it takes a while to accumulate in the system.<br />On a good note taking them in on an empty stomach is not an issue.  If the results are positive I’ll follow up with a review of what’s good.
