Many people like to have regular yoghurts, kefir and other fermented foods to support general gut health, and also a specifically researched friendly bacteria supplement. If you are choosing between capsules and yoghurt or kefir drinks like M&S X ZOE gut shots, consider the pros and cons of each. Our capsules are sugar-free, and tend to cost less, but yoghurt and kefir drinks provide protein and calcium. The best choice depends on personal preference and your individual needs.
