ConcenTrace Trace Mineral Drops
Product Review (submitted on March 16, 2014):
Water kefir grains appear to thrive when product is added to the water & produce better batches of beverage. Also seems to produce more action in first few days veggie ferments. Have also started adding to drinking water of family & pets. I highly recommend this product for those who need to increase mineral intake or having trouble with water kefir grains.
