New research reveals the effect of vitamin D supplementation on immunity

Vitamin D supplementation is touted as one of the best ways to prevent disease, strengthen the immune system, and improve health. But, as with any other case, it is important to find research on the topic in order to better understand the facts, writes Eat This! Not That !.

The authors of the portal state that there are no miracle pills or supplements. They have compiled some facts and the effect of vitamin D tablets on the body.

In general, we all need vitamin D, and most people lack it. The most natural source of vitamin D is sunlight, and spending time outdoors can help increase vitamin D levels.

However, if a person does not work outside all day, then they may need additional vitamin D: at least 600 international units (IU), according to the Mayo Clinic. Most vitamin D supplements contain 1,000 to 2,000 IU, which the clinic claims are generally safe for adults. As you age, you may even need more vitamin D, around 800 IU.

You can try to balance your diet by including foods rich in vitamin D, such as egg yolks, beef liver, cheese, oily fish, including salmon, mackerel, and tuna. In addition, many dairy products or their substitutes are fortified with vitamin D. Cereals and orange juice are additionally enriched with this vitamin.

Vitamin D verdict on immunity

Vitamin D matters because it is one of the key elements that support the normal functioning of the human body. In particular, because it allows the absorption of calcium, which is essential for bone health. It is also involved in the development of muscles and nerves, and in maintaining the immune system. However, how much it supports our immune system is still being studied.

There have been two important studies on vitamin D and the immune system, one of which was small, with a focus on school-aged children. One group was given a vitamin D supplement and the other was not. Those who took this supplement were less likely to get the flu. An additional adult study failed to link vitamin D to fewer upper respiratory tract infections.

So what’s the verdict? It will not hurt to take vitamin D supplements, especially if the person is deficient or suspects that they are deficient. If taken regularly on the recommendation of a doctor, this will only help your health.

But it probably won’t hurt to get sick if you don’t follow other preventive measures: eating a balanced diet, exercising, washing your hands regularly, and getting all vaccinations as recommended by your healthcare provider.
