The cost performance is a maximum level, but The taste is not good. 味は期待しないほうがよいがコストパフォーマンスは最高レベル

Good product for tiredness and improving thyroid

Posted by Reviewer2354141 on Jan 07, 2011

Always have a teaspoon in a glass of water before eating (breakfast). Helps thyroid function. Only complaint is powder could be finer.

Very interesting, definitely useful on dull and dreary days!

I've been having a lot of motivation problems lately, but not anymore! When I take this I feel euphoric for a couple hours, and then just plain good for most of the day. Best to use it only when needed though, as I have found the effects aren't as strong or beneficial if taken daily.

Bigger is better

No complaints but bigger size is better.
