What water-soluble vitamin is not found in significant amounts in milk?

Ascorbic acid, commonly known as Vitamin C, is the water-soluble vitamin that is not found in significant amounts in milk. While milk provides a variety of essential nutrients, including some B vitamins like B12 and folate, it is relatively low in Vitamin C. This is particularly important for people who rely on milk as a dietary staple, as they may need to obtain Vitamin C from other sources such as fruits and vegetables.

In contrast, Vitamin B12 is naturally present in milk and dairy products, making it an important source for individuals who consume these foods. Folate, another B vitamin, is found in lesser amounts in milk but still contributes to the overall nutrient profile. Nicotinic acid, also known as niacin, is another B vitamin that can be found in dairy, although it may not be as significant as in other food sources.

This knowledge highlights the importance of maintaining a balanced diet to ensure adequate intake of all essential vitamins, particularly those not abundant in milk.
