What is Vitamin D?

Vitamin D is a nutrient that the body needs for many important functions, including bone health, muscle function, and immune system health. The body can make vitamin D when it is exposed to sunlight. However, many people do not get enough vitamin D from sunlight alone. In these cases, vitamin D supplements can be used to increase vitamin D levels.

The difference between Vitamin D from sunshine and Vitamin D from supplements

There are several differences between vitamin D from sunshine and vitamin D from supplements. First, the amount of vitamin D that the body makes from sunlight varies depending on a number of factors, including the time of day, the season, the amount of skin that is exposed to the sun, and the use of sunscreen. In contrast, the amount of vitamin D in a supplement is consistent from dose to dose.

Overall, there are both similarities and differences between vitamin D from sunshine and vitamin D from supplements. The best way to get vitamin D is through a combination of sunlight exposure and vitamin D supplements. Sunlight exposure is important because it helps the body to make its own vitamin D. However, vitamin D supplements may be necessary for people who do not get enough sunlight exposure or who have difficulty absorbing vitamin D from sunlight.

If you are considering taking vitamin D supplements, talk to your doctor to determine the right dose for you. Vitamin D supplements can be safely taken by most people. However, high doses of vitamin D can be harmful. Your doctor can help you to determine if vitamin D supplements are right for you and can help you to choose the right dose.
