To balance electrolytes

Posted by CarolynJanson on May 23, 2014

This liquid has done marvels; I recommend it to all whose mineral levels are low, which probably means most of us. It tastes bad, but with only a teaspoon a day it's bearable!

Works great, taste is not good at all

Posted by Reviewer1286511 on Nov 13, 2011

I pour 1/4 of a shot glass and gulp it before a meal and I immediately put some food in my mouth. It's the only way I can tolerate it. I was having lots of muscle cramps and after second week, they were gone. Works well for cramps. 4 stars because it works great. Missing star is for the taste.

M.S. help!

Posted by Reviewer2115344 on Jun 29, 2011

I have M.S., suffer from extremely annoying leg tremors at night, keeping me awake for hours. After 2 weeks of taking Liquid K, tremors have decreased enough for me to get to sleep much quicker! It might be an isolated case, but highly recommend other M.S. sufferers try this if they have the same problem as me. As for the taste, yes, it's bad, but FOLLOW THE DIRECTIONS! Take with orange juice etc.,taste is barely noticeable then. I'll be re-ordering this stuff from iherb for a LONG time, fast,no hassle shipping! Thanks!
