Vitamin D is a fat-soluble vitamin which is crucial for the overall wellbeing of the body. This vitamin is required to maintain healthy bones, muscles, and teeth.

It is also associated with lowering the risk of cancer, diabetes, and other chronic illnesses. Vitamin D is found in certain foods as well as it is synthesized in the body through exposure to sunlight. However, many people do not get enough vitamin D through their diet or sun exposure. Therefore, it is recommended to take vitamin D supplements.

In this article, we will discuss how much vitamin D you should take daily.

Factors to Consider for Vitamin D Requirements

The amount of vitamin D required by a person varies depending on various factors. These factors include:.

Age: As a person’s age increases, the need for vitamin D increases as well.
Health status: People with chronic illnesses or conditions may require higher amounts of vitamin D.
Body weight: Vitamin D is fat-soluble, so people with higher body fat require more vitamin D.
Skin color: People with darker skin are more prone to vitamin D deficiency as the pigment in their skin reduces the amount of vitamin D synthesized through exposure to sunlight.
Geographical location: People living in areas with low levels of sunlight require more vitamin D.

Recommended Daily Intake of Vitamin D

The recommended daily intake of vitamin D varies with age and health status. The table below provides the recommended daily intake:.

Age Group	Recommended Daily Intake (IU/day)
0-12 months	400-1000
1-70 years	600-800
Above 70 years	800-1000

Sources of Vitamin D

Vitamin D is present in certain foods, but it is difficult to obtain the recommended daily intake through diet alone. Some of the dietary sources of vitamin D include:.

Fatty fish like salmon, tuna, and mackerel
Egg yolks
Cheese
Fortified milk and cereal

Sunlight is an excellent natural source of vitamin D. The body can synthesize vitamin D naturally when the skin is exposed to sunlight.

However, the amount of vitamin D produced depends on various factors like geographical location, time of day, season, and skin pigment. People living in areas with low sunlight should consider taking vitamin D supplements.

Vitamin D Supplements

Vitamin D supplements are available in two forms: Vitamin D2 and Vitamin D3. Vitamin D3 is more effective in increasing vitamin D levels in the body. Vitamin D supplements are available in different doses like 400 IU, 1000 IU, 2000 IU, and so on.

The dose of the supplement should be recommended by a health professional based on the individual’s vitamin D status. Excessive intake of vitamin D can be harmful and lead to toxicity.

Vitamin D Testing

Testing for vitamin D levels is important to determine the individual’s vitamin D status. A simple blood test can measure the levels of vitamin D in the body. If the vitamin D levels are inadequate, the doctor may recommend vitamin D supplements.

The doctor may also recommend regular testing to monitor the vitamin D status.

Conclusion

The best source of vitamin D is sunlight, but it is difficult to obtain the recommended daily intake through sunlight alone.
