Summer is almost here, the sun is starting to increase its effect. Then it wouldn’t be possible without mentioning vitamin D, which is known as the sun vitamin, right? Although it is called a vitamin, vitamin D is a hormone because it can be synthesized in the body. Of course, the important thing is not how it is called, but its importance in our body, so let’s get back to our topic.
What are its functions in the body?
Vitamin D increases the absorption of calcium and phosphorus in our body. It is effective in bone formation and protection of bone health. It reduces the risk of osteoporosis (bone loss). Vitamin D, which is absorbed by fatty acids and transferred to the lymph system after being absorbed, is also involved in the immune system.
What Are The Resources?
Although fatty fish such as sardines, salmon, egg yolk and liver contain vitamin D, the main source is the sun. The majority of vitamin D is synthesized in the skin under the influence of sunlight. The amount of synthesis varies depending on the intensity of sunlight and the amount of melanin in the skin. Since brunettes have more melanin pigment, vitamin D production is less.
What Should Vitamin D Levels Be?
To determine the level of vitamin D, the level of 25(OH) vitamin D in the blood is checked. According to this:
>30ng/ml is sufficient
Insufficiency if <20ng/ml
<10 ng/ml is defined as severe deficiency.
What Happens in Its Deficiency?
Vitamin D deficiency is associated with many diseases such as osteoporosis, osteoarthritis, rheumatoid arthritis, rickets, type 1 diabetes and colon, breast and skin cancer.
Those who cannot benefit from sunlight adequately, kidney patients, dark-skinned people, skin patients, pregnant women, the elderly, infants and children are the groups in which vitamin D deficiency is most common.
In addition, studies have shown that obesity may increase the risk of vitamin D deficiency and vitamin D deficiency may cause obesity.
Is Reinforcement Necessary?
To prevent deficiency, 1200IU vitamin D supplements should be given to mothers during pregnancy and lactation, and 400IU vitamin D supplementation should be given to infants until the end of 1 year. Supplementation may be required according to the blood levels of this vitamin, which is also frequently seen in adults. Do not forget to have your vitamin D level measured, especially if you have problems such as bone-muscle pain, mobility weakness or if you are in the risk group.
