Vitamin D is important for keeping bones, teeth and muscles healthy. It helps regulate the amount of calcium and phosphate in the body. The main source of vitamin D is summer sunlight on the skin, but it’s difficult to get enough vitamin D from sunlight during the cooler, winter months. It’s also difficult to get enough from food alone. Although some foods contain vitamin D, such as oily fish, red meat, egg, yolks, and fortified foods. There are few plant-based food sources of vitamin D, and those that exist provide insufficient amounts.

There are two main forms of vitamin D: vitamin D2 and vitamin D3. Studies suggest that vitamin D3 is more effective than vitamin D2 at raising and maintaining your vitamin D levels which may be because vitamin D3 is more similar to the vitamin D that your body produces naturally.

Children aged four and above, especially those who are unable to get sufficient exposure to sunlight, which is the majority of children throughout the cooler months. Also, those who follow a plant-based or predominantly plant-based diet.

Calcium and vitamin D3 are included together because they work together to support bone health. Calcium is a mineral that is essential for building and maintaining strong bones and teeth. Some do not get enough calcium from their diet, especially those you have dietary restrictions or follow a plant-based diet.
