Does the job

Posted by 5454470449863914426 on Apr 28, 2016

I have been taking this effervescent powder for over 5 years now. When I stop taking it, I feel and immediate difference. I play a lot of sports and work as a sports coach. This product gives me the extra vitamins I need to get through the day and to live more vibrantly and sleep more soundly. The sourness can take some time to get used to, but it is a product that does the job!

Strong taste (like lemonade)

Posted by Reviewer2869923 on Oct 01, 2014

I made the mistake to put it in my chocolate shake and that tasted real funny... Didn't realised the taste was that strong. Must say I forget to take it. Must remind myself so I can tell if it works. But the taste is okay, almost like lemonade. Easy to use.
