Vitamin D improves the absorption of calcium and phosphorus, which affects the growth and strength of bones and teeth.
Usually, the body receives vitamin D from two main ways.
1. Foods that are high in vitamin D, such as cooked salmon and mackerel. Moreover, in some countries, vitamin D is added to foods such as yogurt and orange juice.
2. The sun: If we wear short-sleeved shirts or short legs, and our skin is exposed to the sun for at least 15 minutes or more, it will help the body synthesize vitamin D3.
1 of 3 of working-age Thai people are in condition of vitamin D deficiency due to their current lifestyle. There are several lifestyles causing shortage of vitamin D including early wake-up, indoor working, or exercise in the gym, so they are less likely to be exposed to the sun. In addition, applying sunscreen all the time causes the body to synthesize less vitamin D from sunlight. When we get older, we cannot eat all the five food groups, and the vitamin D that we can get from those foods is reduced. Thus, it can lead to vitamin D deficiency.
If the body is lacking vitamin D for a long time, it is likely to cause loss of bone density and osteoporosis in children. In addition, vitamin D deficiency is also associated with certain diseases such as muscle weakness and various types of cancer including breast cancer, colon cancer, and prostate cancer. Moreover, studies have found that vitamin D contributes to increased performance in people with osteoarthritis combined with vitamin D deficiency. Vitamin D is also an antioxidant. Therefore, vitamin D helps slow down the deterioration of the body.
Taking vitamin D in the form of vitamin supplements is an option for people who are wondering or having vitamin D deficiency. However, in case we want to take vitamin supplements, we should consult a medical professional. In fact, the vitamin level in our body should be checked first in order to plan the proper vitamin supplementation. If the body receives excessive vitamin D for a long time, it will adversely affect the body in the long term.
