By GlobalDataJulie Smolyansky, CEO of Lifeway Foods, said in a statement that the new range was “an exciting step forward in functional nutrition”.
She added: “Our goal is to bring together the best of performance and wellness by offering support for strength, recovery, focus and gut health in one convenient and great-tasting format.
“We see opportunities to serve a wide range of consumers, from athletes and fitness enthusiasts to those simply looking to support their overall well-being.
“I am particularly eager to highlight creatine’s emerging relevance for women as more are exploring its potential role in energy, performance and healthy aging.”

Lifeway’s Muscle Mates range marks another expansion in the group’s functional drinks range. In 2024, the business launched a probiotic smoothie with collagen. At the time, the company said the product would be the “first probiotic collagen smoothie with kefir cultures to hit the market”.
