by Ultimate Sup Staff on April 15, 2021

Does the term “sunshine vitamin" sound familiar to you? Today, Ultimate Sup will help you become acquainted with vitamin D3 - an essential nutrient for your body. 

What Is Vitamin D3?

Vitamin D3 (also known as Cholecalciferol) is one of five vitamin D's natural forms. It is the nutrient that your body can synthesize under ultraviolet radiation influences as a fat-soluble one. With this impact, the vitamin D3 synthesis through your skin consists of 2 phases:

  • Stage 1: The metabolized 7-dehydrocholesterol molecule creates vitamin D3 precursor when it is impacted by ultraviolet radiation.
  • Stage 2: The vitamin D3 precursor is self-isomerizing into vitamin D3. This standard self-isomerization period will last about 12 days.
Vitamin D3 is a fat-soluble nutrient that is essential - Ultimate Sup

Once absorbed into your body, vitamin D3 is transferred to the liver. Here, it will transform into a more vital form and then continue another kidney’s metabolic process. Most of the vitamin D3 is stored in your bones to boost the absorption of calcium. Meanwhile, the liver and kidneys will retain the rest to regulate the calcium amount in your blood.

How Important Is Vitamin D3?

Among vitamin D's natural forms, Vitamin D3 and D2 are the most popular. However, vitamin D3 is evaluated as a stronger form, providing more optimal effectiveness and less toxic than Vitamin D2. As a result, they offer more health benefits.

Vitamin D3 participates in inorganic metabolism activities (such as calcium, phosphorus) and epithelial cell differentiation. Therefore, the fat-soluble vitamin promotes the development of strong bones and keeps you healthy.

Benefits Of Vitamin D3 

Benefits Of Vitamin D3

Surely you all know the definition of vitamin D3. Now, let's find out more about its benefits. 

  • Maintain the concentration of Calcium in the blood, supporting to strengthen bones:

When it comes to vitamin Cholecalciferol, the most crucial benefit is balancing and maintaining calcium concentration in the blood. With this vitamin deficiency, the intestine does not absorb enough calcium and phosphorus, making blood calcium decrease. At this time, your body is required to take out calcium from the bones to stabilize. Consequently, children grow slowly. Infants who lack this vitamin can have bone defects. Adults are susceptible to osteoporosis, spongy and fragile bones.

  • Enhancing immunity, preventing cancer: 

According to Dr. John Cannel, ten years ago, an epidemic made many prisoners in a Los Angeles prison experience the flu. However, inmates given Vitamin D 2000 IU per day a few months earlier didn't suffer from the disease. 

Here is another example of vitamin D3 benefits from a clinical study among 67 tuberculosis patients receiving a vitamin D3 supplement of 10,000 IU per day. After six weeks, they didn't have any symptoms of sputum in their lungs. On the other hand, over 77 percent of the vitamin-free group saw some traits. A similar London observation also concluded that vitamin D supplementation has the potential to treat pulmonary tuberculosis.

  • Reduce the risk of cancer:

Women who are supplemented with Vitamin D3 and calcium are nearly 80% less likely to develop cancer. The higher the vitamin D3 concentration, the lower the risk of cancer.

  • Suitable for fetal development: 

Vitamin D3 plays an essential role in fetus development, especially bones, teeth, and skull. Besides, it helps reduce the rate of preterm birth and complications during pregnancy.

How To Increase Your Vitamin D3 Intake


Our body can completely synthesize Cholecalciferol under the impact of ultraviolet radiation. So, the easiest way to get vitamin D3 for your body is to sunbathe. Sunlight is the best natural source to increase this vitamin level. Every day, you should sunbathe for around 15-30 minutes in the morning or in the afternoon. But, you shouldn’t absorb the nutrient from 10 am-3 pm. At this time, the ultraviolet radiation index and the sun exposure will damage your skin, leading to darker skin, long-term skin diseases, even skin cancer.

Eating Foods Rich In Vitamin D3

Your amount of vitamin D3 can be enhanced with a scientific diet. This healthy diet should be full of nutrients, especially the fat-soluble vitamin. Some foods to increase your vitamin D3 intake are fish, fish oil, cereals, acne, soybeans, dairy products, eggs, and mushrooms.
