iHerb Customer Reviews

Must have for asthma.

Posted by healingchildrennaturally on Jun 14, 2016

I use this with magnesium glycinate to stop wheezing in my 11 year old asthmatic son. No more steroids or dangerous side effects for us.

Gave me diahrrea

Posted by Reviewer3089171 on May 17, 2014

This is the second time I've tried these and, both times, they gave me diahrrea and an upset digestive system. I did a little research and found that this is a symptom of overdose, so, apparently, these amounts are too much for my system. So, I'll look for a product with small amounts of the B-vitamins...
