Functional mushrooms for pets
Mushrooms with functional health benefits, such as lion’s mane, reishi, turkey tail, and shiitake, provide prebiotic fibers and immune support amid a more than 150% CAGR in pet postbiotic launches, according to Innova Market Insights data.
Animal supplement product innovations this year demonstrate the increasing “humanization” of pet nutrition to focus on quality and more targeted health positioning.
The category has been expanding with new pet products that mirror mega wellness trends in human nutraceuticals, including metabolism and healthy brain aging.
Among recent new product developments, Lonza Capsugel recently launched UC-Flex, positioned as a premium collagen and calcium carbonate blend for pet joint health.
Meanwhile, in protein innovation, Bond Pet Foods is producing animal-identical proteins using precision fermentation, helping meet the growing demand for sustainably sourced pet food ingredients.
Earlier this year, Nutrition Insight connected with experts from AstaReal, dsm-firmenich, ADM, and Beneo to explore the future directions for pet nutrition innovation, which is expanding into targeted solutions in gut health, cognition, and mobility.
