Vitamin D, also referred to as the “sunshine vitamin”, is a necessary nutrient required for strong bones. It is a fat-soluble vitamin that is synthesized in the skin when exposed to sunlight.

With proper exposure to sunlight, the body makes enough Vitamin D to stay healthy. However, due to lifestyle changes, many people may not be getting enough Vitamin D through sunlight and diet. In this article, we will explore the power of Vitamin D for strong bones.

What is Vitamin D?

Vitamin D refers to a group of hormone-like substances with physiological actions similar to that of a hormone. Vitamin D helps the body absorb calcium and phosphorus, which in turn keeps bones strong.

It is important for several different functions of the body but most commonly for bone health.

How does Vitamin D affect Bones?

Vitamin D regulates calcium and phosphorus absorption, which are minerals that are vital for the body to have healthy bones. The body uses Vitamin D to improve calcium absorption from the intestine and resorption from the bone.

This helps to build bone strength and prevent bone loss.

Why is Vitamin D Important for Bone Health?

Vitamin D helps prevent osteomalacia, a disease that leads to weak and soft bones in adults. The disease is caused by a lack of Vitamin D, which makes it difficult for the body to absorb calcium and phosphorus from food. This, in turn, weakens the bones.

In children, a lack of Vitamin D can lead to rickets, which is a condition that leads to weak bones and skeletal deformities.

How much Vitamin D do you need?

The recommended daily dose for Vitamin D is 600 to 800 IU (International Units) per day. However, it is important to note that the Vitamin D requirements may vary from person to person based on age, gender, weight, and other unique factors.

If you are not sure about your daily requirements for Vitamin D, consult a healthcare provider who can help determine the best amount you need.

How can you get enough Vitamin D?

The best source of Vitamin D is sunlight, but getting enough of it can be challenging, especially in winter months or for those who spend most of their time indoors. The best dietary sources of Vitamin D include:.

Fatty fish such as salmon, tuna, mackerel, and sardines contain high amounts of Vitamin D.

Egg yolks are a good source of Vitamin D.

Fortified dairy products such as milk, soy milk, and yogurt provide a good amount of Vitamin D.

Mushrooms are a good source of Vitamin D when exposed to sunlight or are treated with UV.

Who is at Risk of Vitamin D Deficiency?

Vitamin D deficiency is common, and some groups are at more risk than others. These include:.

Elderly: As we age, our skin produces less Vitamin D, and our kidneys become less efficient at converting it to an active form. This puts the elderly population at a higher risk of Vitamin D deficiency.

People with Dark Skin: Dark skin makes it harder for UVB rays to penetrate through the skin, leading to less Vitamin D production.

People Who are Overweight: Vitamin D is fat-soluble, which means it gets stored in fat tissues. This can make it harder for the body to use the Vitamin D effectively, leading to a deficiency.

People with limited sun exposure: People who spend most of their time indoors, live in northern latitudes, or have religious or cultural practices that keep them covered can have limited sun exposure. This can lead to a deficiency of Vitamin D.

Summary

Vitamin D is an essential nutrient that is important for the development and maintenance of strong bones. It regulates calcium and phosphorus absorption that keeps the bones strong.

Sources of Vitamin D include sunlight, fatty fish, egg yolks, fortified dairy products, and mushrooms. While certain groups are at a higher risk of Vitamin D deficiency, it is important to make sure you are getting enough of it daily to prevent the development of bone-related diseases.
