ConcenTrace Trace Mineral Drops
Product Review (submitted on March 23, 2014):
These mineral drops helped save my kefir grains! I was having problems with my grains deteriorating and creating foul-smelling water kefir (I use carbon-filtered drinking water). I went through the recommended procedures for cleaning and resting sick kefir grains, including adding these drops, and brought my grains back from the brink. Now I use these drops with every batch and my grains are healthy and big. Best of all, no more rotten-smelling kefir!
