Are You Lacking In Vitamin D? Here Is All You Need To Know...

What is Vitamin D?

Vitamin D is well-known for being required for calcium absorption in the intestines, but we are also learning that it has many other vitally important functions in the body, including healthy immunity.

When exposed to sunlight during the summer, the human body can produce a large amount of vitamin D. There are trace amounts of vitamin D in a few foods, but getting enough from diet alone is difficult.

Importance of Vitamin D

Vitamin D helps calcium absorption, which is essential for building and maintaining strong bones. Children with severe Vitality D deficiency can develop rickets, a condition in which the long leg bones become deformed due to a calcium deficiency. Researchers have discovered that Vitamin D has a variety of other important functions throughout the body, including supporting joints and muscles, promoting a healthy mood, and combating a variety of chronic diseases.

Obesity, diabetes, hypertension, depression, fibromyalgia, chronic fatigue syndrome, autoimmune conditions, osteoporosis, and Alzheimer's disease are all common causes of vitamin D3 deficiency. But, especially during this pandemic, it is critical for all of us to understand that vitamin D is required for a strong immune response.

A recent study found that Covid patients with adequate blood Vit D levels are much less likely to have severe reactions to the virus or to die than those with low levels.

Widespread Deficiency

Many people in North America and Europe have Vit D levels that are too low for optimal health, according to surveys, especially during the winter months. Only egg yolk, beef liver, and fatty fish contain (small) amounts of vitamin D.
Some convenience foods (for example, breakfast cereals) contain trace amounts of the D2 form of vitamin D, which is less potent than the D3 found in supplements.

However, getting enough is best accomplished by regularly exposing the skin to sunlight during the warmer months. It is recommended in the United Kingdom and Ireland to supplement vitamin D, at least between the months of November and March, to compensate for low sunlight intensity during this time.

Can you take too much Vitamin D?

Although vitamin D toxicity is extremely rare, it can occur if you consume too much of it. This cannot happen from sun exposure or dietary sources, but it could happen if you take vitamin D supplements for months.
Adults should get 600 IU of vitamin D per day, according to the RDA.

Many scientists who specialize in vitamin D research, however, recommend significantly higher doses to achieve and maintain adequate blood levels during the summer.

Taking up to 4000 IU/day during the winter is generally regarded as safe for most adults (less for children, based on size).
Those with darker skin who live in colder climates are known to require higher doses than those with lighter skin. This is most likely one of the reasons why Covid-19 is more lethal for black people than whites - at least outside of the tropics.


Vitamin D is essential for our health in a variety of ways. There is widespread deficiency throughout temperate regions of the world, and it is known to play a role in diseases such as obesity and diabetes, as well as decreased resistance to coronavirus. I would strongly advise getting a good tan this summer, followed by taking a vitamin D supplement during the winter.
