iHerb Customer Reviews

A great product. Easy to drink.

Posted by JustineGuest on Jan 12, 2017

I use this regularly at the end of each day. I sleep fantastically and I recover from training faster. Palatable (I won't say delicious) and certainly the easiest to stomach that I have found. I recommend this product to family, friends and clients.

Tastes terrible!

Posted by Reviewer1651746 on Dec 12, 2016

I'm only giving this 2 starts because it's made by Thorne. I must have missed the effervescent part but this immediately begins to fizzle when added to water. It makes my stomach hurt. I will go back to taking capsules to get my calcium and magnesium!

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!
