Vitamin D3 & Oil?

In this blog post, we address the question of whether vitamin D3 should be taken with oil. We will first provide a brief overview of the nature and mode of action of vitamin D3 before explaining the reasons for taking it with oil.

Summary: Vitamin D3 - nature and mode of action

Vitamin D3, also known as cholecalciferol, is a fat-soluble vitamin that the human body can produce itself through exposure to sunlight (UV-B rays). It is essential for bone health as it supports the absorption of calcium and phosphate in the intestine and thus contributes to bone mineralization. Vitamin D3 is also important for the immune system and cell division. It's found in animal foods like oily fish, eggs, and liver, but it can also be taken as a dietary supplement.

Why take vitamin D3 with oil?

Since vitamin D3 is fat-soluble, it is important to take it with fats or oils to ensure optimal absorption and utilization in the body. Here are some reasons to take vitamin D3 with oil:

1. Improved absorption

Fat-soluble vitamins such as vitamin D3 need fats in order to be absorbed and utilized by the body. Taking vitamin D3 along with oil improves absorption in the gut as the oil allows for the formation of micelles that transport the vitamins to the gut lining.

2. Higher bioavailability

The bioavailability of vitamin D3 is increased when taken with oil, meaning the body can absorb and utilize more of the vitamin. Studies have shown that the bioavailability of vitamin D3 is significantly higher when taken with oil compared to when taken without fat.

3. Even distribution in the body

Taking vitamin D3 with oil promotes the even distribution of the vitamin throughout the body. The oil helps transport the vitamin D3 into the bloodstream and then store it in adipose tissue, from where it can be released when needed.

Conclusion: Vitamin D3 and oil - a sensible combination

In summary, taking vitamin D3 along with oil is a viable strategy to optimize the vitamin's absorption, bioavailability, and distribution in the body. Therefore, to reap the health benefits of vitamin D3, be sure to take it with a fat source, such as a teaspoon of olive oil, or in combination with a high-fat meal.
