Mare milk is a milk secreted by female horses, known as mares, during lactation to feed their foals. Mare milk is particularly rich in whey protein, polyunsaturated fatty acids, and vitamin C. The beverage kumis is traditionally made from mare milk.
Powdered mare milk is available in several European countries, including Germany.
Mare milk is used in Europe as an alternative for cow milk because of its purported health benefits. While still a niche product, mare milk is considered a remedy for skin or digestive problems. Peer-reviewed papers suggest it can improve atopic dermatitis or eczema. Mare milk is used for manufacturing cosmetic products. It cannot be made into cheese using bovine rennet, but it can be made into cheese using camel-rennet.
