The Sunshine Vitamin: Essential for Bone Health and Much More
Sunshine is the best medicine." - Unknown
Vitamin D3, also known as the sunshine vitamin, is an essential nutrient that plays a crucial role in maintaining strong bones, teeth, and muscles. It is unique in that our bodies can produce it with exposure to sunlight. However, many individuals may not obtain enough vitamin D3 from sunlight and must obtain it from their diet or supplements. In this article, we will discuss the benefits of vitamin D3, its daily requirements, deficiency symptoms, and sources.
Vitamin D3 is also known as cholecalciferol. It is one of the two main forms of vitamin D, the other being vitamin D2 (ergocalciferol). Vitamin D3 is the more potent and biologically active form of vitamin D, and it is the form that is synthesized in the skin when it is exposed to sunlight. Vitamin D2, on the other hand, is obtained from plant sources and is less effective in raising blood levels of vitamin D.
What is Vitamin D3 and Why Do We Need It?
Vitamin D3 is a fat-soluble vitamin that is essential for the absorption of calcium and phosphorus in our bodies, which are necessary for maintaining strong bones and teeth. Vitamin D3 also plays a role in regulating our immune system, reducing inflammation, and supporting overall health.
How Much Vitamin D3 Do I Need Per Day and How Much is Too Much?
The recommended daily intake of vitamin D3 for adults is 600-800 IU (international units), but some individuals may require more, especially if they have limited sun exposure, dark skin, or are over the age of 70. The tolerable upper intake level for vitamin D3 is 4,000 IU per day for adults. Excessive intake of vitamin D3 can lead to hypercalcemia, which can cause nausea, vomiting, and kidney damage.
Top 5 Foods High in Vitamin D3 and Some Alternatives
