    manufactured in JAPAN- remember radiation!

    Posted by Reviewer2776342 on Mar 02, 2013

    thought this was a good product would have rated it a 5star except cant help but realize the implication of getting products sourced from Japan. The nuclear radiation factor is enough to make me look into other sources of co-q. but it doesn't look like i'll have much choice here at iherb.

    Could feel the heart benefit right away, but it upsets my stomach too much to continue !

    Still working on it...

    Posted by Reviewer2865566 on Mar 04, 2009

    I've been using this product only a very short period of time, so I'm not able to say anything yet about it.
