Very good for anxiety, fatigue, appetite, high cholesterol, low HDL cholesterol and other health issues, however, in large doses- above 1g daily- it can cause adverse efects- insomnia etc. Very good price.

Thanks for your feedback!

Hot red skin

Posted by iHerb Customer on Mar 01, 2013 | Verified Purchase

I take this supplement and within 5 minutes i feel me very stranged and hot. I experience a big flush for more than a hour and it was quit uncomfortable and my skin was lobster red. And my skin start itching very much. So i take this not anymore. Next time im buying without the flush reaction...

Thanks for your feedback!

Very good quality

I like that you notice the absorption of this brand right away. You will get a high-intense flush at this level of mg. so beware it comes on fast and is intense. I have noticed that if you eat first and then take it, the flush won't be as extreme. I would not recommend taking it on an empty stomach. I personally like the flush as I know it is working and I am now no longer bothered by it.

Thanks for your feedback!

First took one capsule and the flush was quite something. So if a whole capsule is too much, break it down and sprinkle to your drink or food.
