It works to me

Posted by Reviewer1475859 on Oct 04, 2015

I take only 1 tablet a day because i live in a tropical country and it has an unbelievable thermogenic power. Some minutes after taking it, i m all wet and my temperature goes up, but i don t feel the same anxiety caffeine gives me. So i have the good effects of thermogenesis, but it doesn t change my mood. i m reordering it!

Beware interactions - inhibits intestinal C-Y-P-3-A-4

Posted by Health-Is-Wealth on Jan 04, 2015

C-Y-P-3-A-4 contributes to bile acid detoxification, the termination of action of steroid hormones, and elimination of phytochemicals in food and the majority of medicines. Bitter orange is known to be similar in effect to grapefruit juice and may therefore interact with numerous substances - natural or synthetic. Women naturally have higher C-Y-P-3-A-4 activity than men. However - if C-Y-P-3-A-4 is already overloaded (e.g. estrogen, multiple chemical sensitivity, salicylates), if you are constipated - then taking bitter orange probably isn't going to be useful or fun. I found this product to be effective - and therefore not fun. If this review was helpful to you, please click YES below - thank you.

Works for me

Posted by 4838268174272555644 on Nov 09, 2014

I only use trusted name brand products. When I order online, it is very important to make sure the seller is reputable and your information is protected. Since I have ordered from iHerb.com in the past without any issues with privacy and security, I ordered this product from them. The product's thermogenic property increases the metabolic rate without raising the heart rate. As a result I am motivated and have enough energy to exercise regularly. I will order this product when needed from iHerb.com.
