Frequently Asked Questions
Does milk kefir need salt?
No. Milk naturally contains the minerals and nutrients kefir grains need. Adding salt to milk kefir is not recommended.

Water kefir grains feed on sugar water, which lacks minerals. A tiny pinch of salt, baking soda, or a drop of molasses provides trace minerals the grains need to stay healthy.
