Are There Any Side Effects From Taking Vitamin D
Introduction
Vitamin D is a fat-soluble vitamin that is essential for the human body. It plays a significant role in maintaining bone health, regulating the immune system, and reducing inflammation. Vitamin D can be obtained through sunlight, food, and supplements. However, taking too much vitamin D can lead to side effects.
What is Vitamin D?
Vitamin D is a group of fat-soluble secosteroids responsible for increasing intestinal absorption of calcium, magnesium, and phosphate, and many other biological effects. In humans, the most important compounds in this group are vitamin D3 (also known as cholecalciferol) and vitamin D2 (ergocalciferol). Vitamin D3 is produced in the skin when ultraviolet B (UVB) rays from sunlight strike 7-dehydrocholesterol. Vitamin D2 is obtained from the diet and supplements.
Recommended Daily Intake of Vitamin D
The recommended daily intake of vitamin D varies depending on age, sex, and other factors. According to the National Institutes of Health, the recommended daily intake of vitamin D is as follows:
- Infants (0-12 months): 400-1000 IU
- Children (1-18 years): 600-1000 IU
- Adults (19-70 years): 600-800 IU
- Adults (71 years and older): 800-1000 IU
