Vitamin D: Why Take Dietary Supplements?

When to take vitamin D?

Vitamin D is a substance necessary for the proper functioning of the body. He is involved in many processes. In addition to being usually produced by the latter, it can be provided by various elements such as food and food supplements. Because of its importance, it is an essential contribution to your body.

Every day

There are no desired days for your body to get the right amount of vitamin D. The reason is simple: the need is daily. Indeed, according to the Population Dietary Guidelines (RNP), an adult needs 15 micrograms vitamin D during the day. This quota can be filled with minimal exposure to the sun and proper nutrition.

When you are in the sun for only 15-30 minutes, your skin synthesizes two-thirds of what your body needs. You can take care of the rest with diet. When UVB rays are rare (such as in winter), food supplements can be used. They are ideal for vitamin D supplementation.

During meals

Vitamin D is a fat-soluble substance. This means that it dissolves in your body fat. It is better absorbed there, so it can be stored later if necessary. That is why we recommend taking it only with food.

This will improve its assimilation if they contain fat. Of course, this rule also applies to sources of vitamin D other than food and UVB rays. Therefore, it seems that the best time to optimize the effectiveness of vitamin D supplements is during meals.

Throughout the century

There is no specific age from which it is advisable to start paying attention to the need for vitamin D. It is an important nutrient for all lifetimes; for both the baby and the third-year person. Even if the amount required varies by age group, it is never zero. From the first moments of maturity, your body is highly dependent on this substance. However, for safety reasons, the dose should be strictly adhered to in children.

Why drink vitamin D?

Vitamin D is also important because its deficiency causes many health problems. Due to its involvement in various levels of your metabolism, it is an essential link in the chain. When it weakens or is damaged, the entire structure is endangered. So, providing your body with a vitamin D quota is essential to ensure that you stay healthy.

Avoid bone fragility

Bone fragility is characterized by the inability of bones to withstand relatively low-intensity shocks. This can cause recurrent joint fractures or pain in various parts of your bones. It is caused in part by a deficiency of vitamin D.

When there is enough of it in your body, the absorption of calcium in the food is activated. It is transported safely, reducing damage and settling directly into the bones. As a result, the latter become denser and therefore stronger. This effect of vitamin D is also good for your teeth and the cartilage in your body.

Improve muscle function

In addition to being good for your bones and teeth, vitamin D is also good for your muscles. Numerous studies have shown that it has a direct effect on mitochondria. They are similar to muscle cell batteries.

The more energy they have, the healthier your muscles are. Vitamin D increases this energy level to maximize your muscle function. In fact, it contributes to recovery after a workout. Your muscles regenerate faster while experiencing as little pain as possible. This ensures good muscle stimulation at the cellular level.

Optimize nerve transmission

Nerve transmission occurs through ion channels. These are certain marked circuits composed of transformed materials that promote the transmission of electrical impulses. These substances are usually positive ions such as calcium and potassium. When in large quantities, the channels multiply and nerve transmission is greatly improved.

This process is possible due to vitamin D, which increases the amount of calcium in your body. Thus, it indirectly contributes to the optimal transmission of neural messages. You become more alive. This can improve your concentration to some extent.

Strengthen the immune system

Vitamin D is a great support for your immune system. It supports it to improve its performance and protection against viruses. It stimulates important components of the immune system. These are macrophages and dendritic cells. For example, the latter are involved in activating the immune response.

It is therefore clear that vitamin D improves the body’s response to aggression. Increases the number of Th2 lymphocytes that help fight inflammation. Finally, this substance is involved in the production of antimicrobials. In other words, it plays a crucial role in the removal of pathogenic elements.

To help your body take full advantage of vitamin D, take the time to stay in the sun on a daily basis. But be sure to protect yourself with, for example, sunscreen. It is also found in certain foods such as fatty fish (mackerel, salmon, sardines, herring), eggs and dairy products. Also think about dietary supplements to avoid vitamin D deficiency.
