The level of vitamin d in the body is influenced by these 6 factors

Did you know that there are about one billion people worldwide who have vitamin D deficiency, and the incidence is mostly in the Middle East and Asia? This is a serious problem because deficiency, aka lack of vitamin D, can lead to low immune system, slow skin regeneration process when an injury occurs, impaired bone growth in children, and reduced energy.

Sun exposure (UVB radiation) is the main source of vitamin D production in the body, although vitamin D can also be obtained through food intake or supplements. But apart from that, differences in lifestyle and various other factors also affect the process of absorption of vitamin D in the body. To avoid vitamin D deficiency, you need to be aware and take proactive steps to fight the factors that affect absorption.

What affects vitamin D levels in the body?

The following are various factors that can affect the levels of vitamin D in your body:

1. Skin color

Melanin, aka skin dye, "competes" with a substance in the skin to absorb UVB rays. This means that the more melanin you have (that is, if you have a darker skin tone), the more likely you are to have a vitamin D deficiency. Dark skinned people need more time in the sun, or may need to take vitamin D supplements at a high level. higher.

2. Use of sunscreen

Aka sunscreen sunscreenis often recommended by doctors to prevent sunburn, skin cancer, and excessive skin aging. While this is true, the wrong use of sunscreen can actually increase the risk of cancer due to its strong blocking action against vitamin D.

Sunscreen works by blocking UVB rays, the rays that are important for activating the production of vitamin D. So, to avoid the bad effects of sunlight without having to be hindered by its benefits, read here for how to use sunscreen to stay safe.

3. Air pollution

Organic particles from burning wood, fossil fuels, and other pollutants are scattered in the open air and can absorb UVB.

4. Weight loss

Body fat absorbs more vitamin D and serves as a storage center for nutrients. Having a healthy body fat percentage can help to ensure adequate vitamin D levels throughout the year. However, that doesn't mean excess body fat is good, as research has also shown that obesity is associated with low vitamin D levels.

5. Season and location

During winter, the amount of UVB rays that can reach the earth's surface decreases due to the low angle of the sun. This is especially true the further away from the equator.

6. Age

Compared with young people, older people have lower levels of substances that convert UVB rays to precursors of vitamin D. This means that older people are less efficient producers of vitamin D than young people. This is related to the reduced function of the organs that participate in the processing of vitamin D in the body, especially the liver, kidneys and intestines.

To find out if you need to supplement with vitamin D, you need to consult a doctor first because the levels needed by each person are different. If you need supplements, your doctor will advise you on the right amount of supplement for your needs.
