Sure, let’s break this down:

- Vitamin K – This one’s fat-soluble. Your body stores it in fat tissue. It plays a big role in blood clotting.

- Vitamin D – Also fat-soluble. Your body uses sunlight to make it and stores the extra. Helps your bones absorb calcium.

- Vitamin C – Here’s the winner. ?? It’s water-soluble, which means your body doesn’t store much of it and you need a regular supply. Boosts your immune system and helps skin, blood vessels, and more.

- Vitamin A – Fat-soluble too. Good for vision, skin, and immunity, but again, your body stores it.
