Which type of milk has a higher concentration of vitamin K?

Cow's milk contains a higher concentration of vitamin K compared to the other types of milk listed. Vitamin K is essential for processes like blood coagulation and bone metabolism, and its levels can vary significantly between different milk sources.

In contrast, goat's milk, while nutritious, has slightly lower vitamin K content compared to cow's milk. Breast milk is formulated to meet an infant's nutritional needs, but it typically contains lower levels of vitamin K relative to cow's milk, which can lead to a higher incidence of vitamin K deficiency in exclusively breastfed infants unless supplemented. Almond milk generally has negligible vitamin K levels, as it is primarily made from almonds with added water, and often lacks many of the nutrients found in animal milks or even breast milk.

Thus, cow's milk stands out as the source with the highest vitamin K concentration among the options provided.
