Why is Vitamin D Essential?

Category: Health  

Vitamin D! An essential vitamin which has many important functions to support our bodily functions. For instance, the most important factor it is responsible for is regulating the absorption of calcium and phosphorus while supporting a healthy immune system. Providing our bodies with a sufficient amount of vitamin D is important for normal growth and development of teeth, bones, as well as improved resistance against certain diseases.

Furthermore if our bodies don't get enough vitamin D, we may be at risk for developing bone abnormalities. So the good news is, there are plenty of ways to get sufficient amounts of vitamin D in your diet!

Health Benefits of Vitamin D

So why is Vitamin D essential? Vitamin D correlates with many health benefits according to its capability of influencing our genetic transcription. Here are a list of vitamin D’s displayed health benefits:

Enhances healthy bones – Vitamin D promotes the absorption of phosphorus and calcium. Both, calcium and phosphorus are essential for maintaining bone health. For example a vitamin D deficiency in a child may cause softening and weakening. For an adult it is referred to as, osteomalacia (softening of the bones) or osteoporosis.

Vitamin D promotes cell growth/cell-to-cell communication. Various studies have shown that a hormonally active form of vitamin D may slow or even reduce the growth of cancer. This happens because of cellular differentiation. When cancer cell growth is decreased it stimulates cell death while preventing angiogenesis/new blood vessel formation.

Boosts immunity - Vitamin D enhances the expression of genes which have a great influence on our immune system. Furthermore, this means that Vitamin D helps our body's attack and destroy viruses, bacteria and infections. This also includes the common cold and flu.

Reduces the risk of diabetes - Vitamin D has shown that it may help reduce the risk of insulin resistance. Therefore it may improve our body’s sensitivity to insulin -the hormone responsible for regulating blood sugar levels. Insulin resistance usually occurs before type 2 diabetes.

Vitamin D has also been linked to a decrease in the risk of cardiovascular disease

Different forms of Vitamin D


There are different forms of vitamin D. The most important for humans are vitamin D2 and vitamin D3.

  • vitamin D2 is synthesized by plants.
  • vitamin D3 is synthesized by the skin when it is exposed to ultraviolet B (UVB) rays.

Vitamin D is not actually a vitamin, but rather a pro-hormone. When our body is exposed to or receives, vitamin D, it activates the vitamins in the liver and kidneys. This activation process (known as vitamin synthesis) turns the vitamin D into a hormone. We can access vitamin D via sun exposure as well as with a limited number of foods, and supplements.

In supplements and fortified foods, vitamin D can be either D2 or D3. The two forms have traditionally been regarded as equivalent based on their ability to cure rickets, but evidence suggests that vitamin D3 is approximately three times more effective at maintaining serum concentrations because the binding protein has a higher potency to vitamin D3 than vitamin D2. This allows vitamin D3 to reside in the circulatory system longer and increase the concentration to sufficient levels more quickly. The major preparations of vitamin D for prescription use in North America are in the form of vitamin D2, while more over-the-counter vitamin / multivitamin preparations use vitamin D3.

Whether it is absorbed through unprotected skin or ingested then absorbed by the intestines, vitamin D is bound to the binding protein (both albumin and vitamin D binding protein) and carried to the liver via the bloodstream. From there it begins two hydroxylation processes. Beginning in the liver it is transformed into 25(OH)vitamin D (calcidiol), which is the primary circulating form of Vitamin D and the most commonly measured form in serum. Then in the kidneys it is transformed into 1,25 dihydroxy-vitamin D (calcitriol), which is the biologically active form of vitamin D.

Foods that provide vitamin D include: fatty fish, like tuna, mackerel and salmon.

A reliable source of energy

Codeage’s high-potency ADK Vitamins is a convenient source of streamlined, long-lasting support that strengthens your bones, heart and immune system. Support your bone structure, calcium absorption and heart health with Codeage ADK vitamins.*

Vitamin D, also known as the sunshine vitamin, is considered the most important supplement under the sun—and for a good reason. Vitamin D supports everything from bones, heart health to mood. But, how often has someone recommended combining your high-dose of vitamin D with vitamin K and vitamin A? Together, these three powerful vitamins join forces to support your bones, heart, and immune system. Here’s how it works. Vitamin D plays a critical role in calcium absorption into the bloodstream. Vitamin K is required to transport calcium from the bloodstream into the bone, supporting bone density and cardiovascular health. Additionally, vitamin A works with vitamin D to support your immune system. ADK is a convenient source of streamlined, long-lasting support that strengthens your bones, heart, and immune system.

Take this supplement just once every day to complement a healthy diet and lifestyle.*

Provide your body with enough vitamin D

Vitamin D is sometimes referred to as the sunshine vitamin because it’s produced in your skin in response to sunlight. It’s a fat-soluble vitamin in a family of compounds that includes vitamins D-1, D-2, and D-3. Your body produces vitamin D naturally when it’s directly exposed to sunlight.

Factors that impact the ability of the body to synthesize vitamin D through the skin are geographic latitude, time of year, time of day, presence of clouds and/or smog, skin melanin content, and whether or not sunscreen has been applied. To get a sufficient amount of vitamin D, you may also get it through certain foods and supplements to ensure adequate levels of the vitamin D in your blood.
