London-based Rhythm Health has introduced a line of non-dairy kefir beverages made with coconut water. Naturally occurring electrolyte salts in the coconut water offer benefits for hydration, in addition to potassium, magnesium and sodium. As a result of the fermentation process, the live drinks feature lactic acid bacteria, including the probiotic strain Lactobacillus acidophilus. Each drink has no added sugar, is cholesterol-free, and offers a variety of beneficial vitamins, minerals and nutrients. Rhythm offers three tropical flavors—Coconut, Mango & Passionfruit; Coconut & Pomegranate; and Pure Coconut.
