Vitamin D is a nutrient that is beneficial for bone formation. Vitamin D is also needed by the body to maintain a healthy heart, brain and muscles.
Vitamin D is formed naturally when the skin is exposed to direct sunlight. In fact, most of the need for vitamin D is met through exposure to sunlight. In addition, vitamin D is also contained in several types of food, such as mushrooms, egg yolks, and fish.
When calcium levels in the body decrease, the parathyroid glands will stimulate the intestines and kidneys to produce vitamin D to absorb more calcium.
However, not a few people who experience vitamin D deficiency. This usually occurs when the body does not get enough sunlight, or is not effective at absorbing vitamin D. In these conditions, supplements are needed to prevent vitamin D deficiency.
The main types of vitamin D are vitamin D2 and vitamin D3. Vitamin D2 comes from plants and foods fortified with vitamin D2 itself, while vitamin D3 comes from animals. Both types of vitamins are available in the form of tablets, capsules, and syrups.

How to use Vitamin D Properly
Vitamin and mineral supplements are consumed to complement the body's need for vitamins and minerals, especially when the intake of vitamins and minerals from food cannot meet the body's needs. Keep in mind, supplements are only used as a complement to the body's nutritional needs, not as a substitute for nutrients from food.
There are several conditions that require the intake of supplements, such as being stricken with an illness, pregnant, or taking drugs that can interfere with the metabolism of vitamins and minerals.
Take vitamin D supplements according to the directions on the package. Vitamin D should be taken with food so that it is more easily absorbed by the body.
If you want to take vitamin D in syrup form, use the measuring spoon included in the package. Don't use a regular tablespoon because the measurements will be different.
