Marks & Spencer has partnered with nutrition-science company Zoe to launch a new M&S Food x Zoe Gut Shot, marking what the retailer describes as a “world-first” collaboration in gut health-focused beverages.

The product is the result of 12 months of joint product development and aims to bring Zoe’s microbiome research and nutrition expertise to M&S customers.

The creamy gut shot is made with British whole milk, kefir, berries, and plant-based ingredients such as baobab and pomegranate. It contains no added sugar, sweeteners, artificial gums or emulsifiers, while delivering over 5 billion live cultures from 14 strains of beneficial bacteria. The shots are also high in fibre and a source of calcium, targeting consumers seeking functional and gut-friendly nutrition.

Alex Freudmann, Managing Director of M&S Food, commented:

“We always ensure a healthy choice is a delicious choice, and we’re proud to be at the forefront of gut health innovation. The M&S Food x Zoe Gut Shot combines the nutrition science expertise of Zoe with the quality, innovation and product development capabilities of M&S Food.”

Jonathan Wolf, co-founder and CEO of Zoe, added:

“At Zoe our mission is to improve the health of millions. We run the world’s largest microbiome and nutrition research study and are committed to bringing expert-led science to consumers. Partnering with M&S allows us to make this delicious product available in supermarkets nationwide, helping more people improve their gut health.”

The gut shots are available in M&S stores nationwide at an RRP of £2, with a free gut health guide included with every purchase.

This launch coincides with M&S’s broader ‘Good Gut’ range, which features more than ten products including cereals, yogurts, and drinks designed to support digestive health.

The collaboration highlights a growing trend among retailers and brands to bring functional, science-backed products to mainstream grocery channels, responding to rising consumer demand for gut-friendly and health-enhancing foods and beverages.
