Although 100% suitable for vegetarians, traditionally made kefir is not vegan suitable, having been produced using a fermentation of kefir grains and dairy-based milk.
However, an increasing number of wholly vegan kefir products are now available, made using alternative milks including soy, nut and oat milk. Some are also made with natural water or even coconut water.
Nonetheless, it is vital that those following a vegan eating regime look out for the appropriate labelling because many products, even those made using milk alternatives, may contain flavourings such as honey, which are not vegan suitable.
