Which vitamin is commonly fortified in milk?

• A. Vitamin D
• B. Vitamin A
• C. Vitamin C
• D. Vitamin K

Answer: (A)

Fortifying milk with vitamin D is a public-health strategy aimed at improving bone health by ensuring people get enough vitamin D, which helps the body absorb calcium. Milk is a widely consumed, convenient vehicle, so adding vitamin D raises intake across diverse populations, especially where sun exposure is limited or dietary sources are low. This practice has a long history in nutrition programs and remains common today. Vitamin C isn’t typically added to milk because it’s unstable in dairy processing and isn’t a natural focus of milk’s nutrient profile; vitamin K isn’t routinely fortified in dairy, and while vitamin A has been added in some milk products, vitamin D is the standard fortification to support calcium metabolism and bone strength.
