Vitamins of group D and their effect on the body: expert recommendations

It is impossible to exaggerate the importance of vitamins for maintaining the beauty and health of the body. Vitamins of group D deserve special attention: cholecalciferol or vitamin D3, which is synthesized in the skin under the influence of ultraviolet rays, as well as ergocalciferol or vitamin D2, which enters the body with food.

In an exclusive interview for estet-portal.com, candidate of medical sciences, therapist of the highest category and anti-age medicine specialist Nadezhda Kryzhanovskaya spoke about the effect of group D vitamins on the health and beauty of the body, as well as about how to avoid their glut and scarcity.

Tell us about the effect of D vitamins on the human body

N.K. Vitamins of group D are involved in the absorption of calcium and phosphorus, and these are the key moments of muscle contraction, bone density, and skin density as well. They also take part in neural transmission. If a patient is deficient in  vitamin D and calcium – it is rickets and weak, painful bones.

Subdeficit – these are exposure to the risk of osteoporosis, a weakened immune system, oncological alertness. There are also studies that show that these patients are more likely to suffer from the cardiovascular system. Vitamin D is also one of those vitamins that can be overdosed.

In this case, the patient may experience vomiting, constipation, impaired digestive function and muscle atony.

What is the relationship between D vitamins and skin condition

N.K. Leather – this is the main organ where vitamin D is transformed, so a lot depends on the health of the skin. The darker, darker and tougher the skin, the longer a person needs to stay in the sun to get those precious drops of vitamin D3 that will affect his general condition.

Since the skin reflects our complete well-being, it is definitely wrong to say that if a person takes vitamin D, he does not need to go to a beautician. This is just one of the bricks. But if the body is under stress due to the fact that it has a lack of vitamins of group D, this will affect the condition of the skin.

As we know, under the influence of ultraviolet rays, vitamin D3 is synthesized in the skin. At the same time, ultraviolet light provokes photoaging processes. How to keep the balance?

N.K. This is a very interesting concept, because not only photoaging, but also skin cancer is triggered by direct sunlight. And vitamin D3 is predominantly produced precisely when exposed to ultraviolet radiation at a time when the sun is especially aggressive. In order to be in the security zone, you must follow a few rules very clearly.

Exposure to sunlight should occur from 10.00 to 15.00, on open large areas of the body, for fair-skinned people - for 5-10 minutes, for dark-skinned people – up to half an hour.

If this exposure occurs several times a week, between April and October, this is enough to get enough vitamin D.

How can a specialist suspect that a patient is deficient in vitamins of group D

N.K. If the patient is not exposed to the sun, if, for example, he is a vegetarian or lactose intolerant and avoids dairy products, if he lives in northern latitudes or has sun intolerance – he will definitely be deficient in vitamins of group D. In addition, it is important to remember that the ultraviolet, which is needed to produce vitamin D3, does not penetrate through glass and through sunscreens.

In case of deficiency of vitamins of group D, the patient is recommended to take medications. How effective is taking synthetic vitamins?

The chemical molecule of synthetic vitamins is absolutely identical to natural ones. It has already been proven that synthetics and natural vitamins – This is the same. But, naturally, when we get natural vitamins, they are more predictable in the way they degrade. Therefore, I can reassure people who cannot afford expensive natural vitamins. If they replace them with synthetics – nothing bad will happen to their body, and the risk of mutations will not increase.

How to avoid vitamin D overdose when treating a patient

N.K. Vitamin D is the product that I would recommend to prescribe only under blood control. A very good marker is 25-hydroxycholecalciferol.

To the extent possible,  to remove the patient from the risk zone of cancer, 25-hydroxycholecalciferol in the blood should not be less than 80 nmol / l, but not more than 125 nmol / l, since, in this case, the patient is at risk of oversaturation.

If I prescribe vitamin D supplementation, I make sure to monitor patients before, determine their dose and monitor after. Each patient has his own dose, which depends very much on the time of year, and even on the degree of residence in latitude. The further north – the more vitamin D you need. 

What dosages of vitamin D do you recommend?

N.K. If a patient has 25-hydroxycholecalciferol  is 30 nmol / l and below, it is necessary to give him full supplementation. Here the opinions of experts differ: the standard European orthodox dosage is 600 IU per day.

From the position of the Americans, this is very little – as a therapeutic dose they consider 5000 IU. Based on this, I recommend taking the arithmetic mean, for example 2000 IU, and doing a blood test in the first month of treatment.  If 25-hydroxycholecalciferol  entered the comfort dose and keeps around 80 nmol / l, the blood test should be repeated after 2 months. If, by this time, the marker has risen to the level of 120 nmol / l, the drug should be stopped.

If we are talking about patients at risk who need constant medication, then an average dose of 1000 IU can be prescribed, monitoring vitamin D approximately every 3 months.
