Which two vitamins are formed with the help of probiotics?

Explanation:
Probiotics help the gut produce certain vitamins that the body can use. Vitamin K is a well-known one produced by intestinal bacteria, contributing to blood clotting and bone health. Some gut microbes also synthesize B vitamins, particularly B12 (cobalamin), which supports nerve function and blood cell formation. The other vitamins listed—A, C, E, and D—are not produced by gut bacteria in meaningful amounts; they come mainly from food, sun exposure (for D), or are absorbed from the diet. So the two vitamins formed with the help of probiotics are vitamin K and vitamin B12.
