I have been making and drinking kefir every day for several years .... if you've never heard of it - try an internet search ! There is stacks of info out there .. all good !

It's the best probiotic you can get, but it's not promoted commercially, or advertised because you make it fresh at home each day. You cannot buy it, as it is a living culture ( as yogurt is a culture) and is passed on from person to person.. It's so much better than any probiotic dried pills ..

Kefir is made and drunk every day in hundreds of countries by millions of people.
