Vitamin D: A source of health for our body (Part II)

There is a common belief that there is only one type of Vitamin D. In fact, there are several. Of these, those that interest us for our health are D2 and D3.

Vitamin D2 is a prohormone that is mainly found in fungi as of ergosterol molecules in combination with ultraviolet radiation from the sun. Some plants contaminated with fungi are capable of having Vitamin D2 in their composition.

On the other hand, Vitamin D3 is generated by plants in their normal state and by animal cholesterol molecules together with the interaction of ultraviolet light.


Vitamin D3 or D2: which one is better?

Until recently it was believed that both forms of Vitamin D were similar. However, clinical trials have shown that D3 is much more beneficial.

Clinical studies have revealed that Vitamin D3 is much more effective than D2. People who take Vitamin D3 get twice the level of Vitamin D in their body, compared to those who take Vitamin D2.


Fortification of food with Vitamin D

In recent years, many retailers in the food industry have enriched their products with Vitamin D2 in the belief that it meets the daily needs of consumers. However, clinical studies have shown that Vitamin D3 is much more effective than Vitamin D2.

People who eat foods that contain Vitamin D3, such as fish, eggs, or Vitamin D3 supplements, increase their Vitamin D levels much more than people who eat foods that contain Vitamin D2, such as bread or milk enriched with Vitamin D2 or dietary supplements of Vitamin D2.


Curiosities of Vitamin D

It has been proventhat 90% of Vitamin D is produced directly in the body using UVB radiation from the sun and that only the remaining 10% is acquiredthrough diet.

The farther we live from the equator, the darker skin we have, the more overweight we are and the less exposedwe are to the sun, in those cases we should be taking more Vitamin D supplements, either through food or as a dietary supplement, to achieve healthy blood levels of this vitamin.

Walking for 20 minutes a day in winter may be well-intentioned advice, but it is not enough to synthesise the amount of Vitamin D needed for our body.

Vitamin D has an antimicrobial effect by enhancing the immune system as well as anti-inflammatory properties. Thus, it plays a decisive role in preventing acute or chronic inflammation and accelerating the healing process.

Vitamin D is used to prevent Alzheimer’s, as it facilitates communication between nerve cells and therefore, protects them from long-term death.

Russian and German athletes have used the benefits of the sun to improve physical performance for the past 30-40 years. They knew that Vitamin D promotes muscle efficiency and endurance, and, therefore, helps improve sports performance.

Clinical studies show that Vitamin D is essential for maintaining optimal conditions of our brain and state of mind and that its deficiency can lead to depression.

With age, the body gradually loses the ability to synthesise Vitamin D through sunlight. At the same time, the age increases the body’s need for Vitamin D.

Antidepressants, anticoagulants, corticosteroids, and medications to treat peptic ulcer and epilepsy may inhibit the absorption of the Vitamin D we take through our diet. Also, people with heavy alcohol consumption may be at increased risk of Vitamin D deficiency. They are advisedto take Vitamin D as a supplement.

Vegans, in particular, are at higher risk of Vitamin D deficiency, as this vitamin is usually contained mainly in foods of animal origin. However, mushrooms and avocados also contain Vitamin D2 and a precursor of Vitamin D3.

Sunscreens prevent the synthesis of Vitamin D. For that reason, to get our body to generate Vitamin D, we should walk for 10-20 minutes without sun protection and then apply the sunscreen.

However, the sun exposure poses a dilemma, while it may be useful for producing Vitamin D, which protects us against certain types of cancer, osteoporosis, Alzheimer’s and other diseases, it is worth considering whether it can cause skin cancer.

We have always talked about Vitamin D as something essential to strengthen our bones. However, it is now knownthat further to keeping our bones and teeth healthy, it intervenes in the functioning of almost every organ and tissue in our body. More specifically, it is essential for the metabolic process of the intestine, brain, heart, pancreas, skin and lymphocytes.

That is why a deficit of Vitamin D affects our whole body, and it is essential to re-establish its normal, required levels as soon as possible.


Vitamin D protects our health and prevents us from possible illnesses

Maintaining proper levels of Vitamin D in our body is imperative. Because, apart from its benefits for our bones, Vitamin D prevents the onset of a large number of diseases:

  • Autoimmune diseases
  • Common cold
  • Bone diseases (including rickets)
  • Osteoporosis
  • Bone and back pain
  • Depression
  • Diabetes
  • Cardiovascular diseases
  • Hypertension
  • Chronic inflammation
  • Disorders of the immune system
  • Muscle weakness
  • Psoriasis
  • Rheumatoid arthritis
  • Neurological diseases
  • Alzheimer
  • PMS
  • Cancer

We cannot say that these diseases are caused solely by a deficiency of Vitamin D. However, researchers believe that the lack of Vitamin D is a decisive factor contributing to the development of these pathologies and that, on the other hand, we can minimise their risks by maintainingadequate levels of Vitamin D.


Threedifferent ways to get Vitamin D

Our body can obtain its daily needs of VitaminD in 3 different ways:

  • Daily sun exposure can provide an indirect source of vitamin D. Although sunlight itself does not contain Vitamin D, it promotes the synthesis of this vitamin in the body. Healthy exposure to the sun’s UVB rays is the most natural and practical way to achieve the right levels.
  • By eating natural foods that contain this vitamin: oily fish, butter, milk, egg yolk, cheese…
  • There arevitamin D supplementsthat become a good option for people with vitamin D deficiency. They are practical and very effective.

Symptoms of a Vitamin D deficiency

Many symptoms makeus suspect that a patient has a deficit of Vitamin D:

  • Rickets in children
  • Osteomalacia (softening of the bones)
  • Osteoporosis(fragile bones)
  • Musculoskeletalpain
  • Susceptibility to allergies
  • Respiratory tract infections
  • Organic pain


These symptoms improve and even disappear when the level of Vitamin D in the body normalises.
