Who is affected by vitamin D deficiency?
Vitamin D deficiency affects a large part of the world population. The most modest studies estimate a shortage of 30%. Other experts say that up to 80% of people have a lack of calcitriol. A sedentary lifestyle and less exposure to sunlight are the main culprits.
The groups that have a higher risk of suffering from a vitamin D deficiency are the following:
Adults over 55: As we age, the skin reduces its ability to synthesize cholecalciferol.
Office workers and students: They spend most of their time indoors and don’t get much exposure to sunlight.
Dark-skinned people: The increased amount of melanin in the skin hinders the creation of vitamin D.
Vegans and Vegetarians: Ergosterol is more difficult to absorb and use than animal-derived vitamin D.
People who often use sunscreen: This product blocks UVB rays and prevents the formation of vitamin D.
People with chronic intestinal diseases: They have difficulty assimilating vitamin D in the digestive tract.
Benefits of Vitamin D?
A balanced supply of vitamin D is essential in various pathologies:
-
- bone problems, such as fragility and osteoporosis
- pain in the pelvis and legs
- muscle spasms
- performs an antitumor action
- stimulates the immune system
- benefits the brain and nervous system
- supports lung function and cardiovascular activity
In addition to regulating the level of calcium, vitamin D also helps to regulate that of phosphorus and the absorption of vitamin A. It is useful against rickets, a childhood disease with serious consequences on growth.
What Vitamin D Supplements?
In the event that the diet and exposure to the sun are not sufficient, it is necessary to take the supplements, first having a diagnosis made by the specialist doctor who must assess the actual need.
Vitamin D supplements that are on the market mainly provide a supply of vitamin D3. In fact, studies identify vitamin D3 as the most bioavailable and immediately effective form of vitamin D to ensure the right concentrations of this nutrient in the blood.
To become biologically active, vitamin D must undergo double hydroxylation, first in the liver and then in the kidney. Once activated, it therefore behaves like a real hormone, acting above all in the intestine to enhance the active absorption of dietary calcium.
It therefore contributes to the stability of the calcium level and to its adequate bone mineralization.
Vegan or vegetarian nutrition
If you have decided to follow a strict vegetarian diet, pay special attention to your vitamin D supplement. Vitamin D3 comes from animal sources such as oily fish oil and is not suitable for vegans. D2 or ergocalciferol supplements are the only ones of 100% plant origin.
There are manufacturers who advertise their supplements as “vegan vitamin D3”. For example, one company consulted claims to have obtained cholecalciferol from a lichen. It is difficult to guarantee the veracity of these promises, so if you want to be sure that you are consuming a 100% vegan product, we recommend using ergocalciferol.
