Reviews For CircO2^® Nitric Oxide

I must have missed the 'DO NOT TAKE IF YOU ARE TAKING BLOOD THINNERS' part in your promotional material. When I read the fine print in the first pack of lozenges there it was! I tried to schedule the one a day recommended in the pack as far away from the blood thinner dosage as I could but I couldn't handle it. Then after a hiatus of about a week I thought I'd give it another try. Still no go (I wound up passing out for a few seconds and experienced a great deal of distress of various kinds) so I will be calling on Monday next to arrange a return of the product.

The supplement did nothing for me. I returned the order for a refund..

This product may work for some, but not me. I could go on to say the product looks like and taste like Tums the antacid.

I took one tablet as instructed. I have never had such a bad headache. I tried a half and got the same reaction. Product obviously does what it is said but beware the chance of violent headaches.

Guys I'm sorry but I can't stand the weird flavor! Any recommendations?

Every time I took Pill as instructed.. next day or so..... sores would appear on my legs between my Knee and Thigh......Three to four Large Red Pimples

Took as directed for four weeks. Zero impact. Don't waste your money

This product had no effect whatsoever on me. It did not boost my energy levels in the slightest.

it is like many other things that are on the market that the results of taking are questionable at best. The price of it makes it seem out of line compared to other products that can be bought at a lower price at a health food store. Hard to recommend when did not notice results

Unfortunately the product has caused gut irritation, it's very acidy.
