Why is vitamin D needed?

Vitamin D production is triggered in the skin by UVB rays from the sun.

Vitamin D is often talked about, but why is it so important to get enough of it? Vitamin D is a key factor in calcium absorption and thus affects bone health. Additionally, vitamin D supports the immune system and has many other benefits for various reactions in the body.

Vitamin D may even protect against severe forms of COVID-19

It has been observed that normal levels of vitamin D can protect against severe forms of COVID-19. It is believed that vitamin D helps regulate the body’s immune system by preventing overactivation. Ensuring adequate vitamin D intake seems to be linked to lower morbidity and a reduction in mild inflammatory markers.

This is good news for Finns, as our vitamin D levels and intake are generally at a good level, according to the Finnish Institute for Health and Welfare’s FinRavinto 2017 study. Additionally, Finns are well aware of the need for sufficient vitamin D intake.

Vitamin D needs are individual

Some people naturally have more circulating vitamin D in their blood than others, which allows them to better utilize the benefits of vitamin D. Vitamin D supplements also increase blood levels of vitamin D more in these individuals than in others.

In some cases, however, the body’s ability to utilize vitamin D may be impaired. This can lead to vitamin D deficiency. Obesity and diabetes have been found to explain vitamin D deficiency. In such cases, the body cannot utilize vitamin D in the normal way. Severe deficiency increases the risk of upper respiratory infections, among other things. If the body cannot properly utilize vitamin D, supplementation is necessary.

Natural levels can be determined through DNA testing

Vitamin D levels can be measured through a blood test. However, it’s important to remember that a blood test only reflects the current level of vitamin D. Factors such as the season or diet can affect this.

If you want to determine your body’s natural vitamin D level, you can turn to DNA testing. This will reveal your vitamin D level based on your genes. Evogenomin Feel+ and Vitamiinit products provide this information. In addition to your natural vitamin D level, Evogenomin products give you a comprehensive genetic analysis of your tendencies and characteristics. Your personal analysis will provide you with basic information on how your body functions due to your natural genetic makeup and the possibilities you have
