The Eczema of her son gets worse in winter?

A kind of common treatment for severe eczema (especially during the winter months) has been exposing the skin to ultraviolet light, which in practice stimulates the production of vitamin D (obtaining of vitamin D from endogenous cholesterol is synthesized by the incidence of UVB rays of the sun on the skin).

In fact, several studies have been conducted to determine the levels of vitamin D present on the skin of people with eczema, as well as the effects of vitamin D in the treatment of eczema.

Studies with vitamin D and Eczema: randomized controlled trial with supplementation of vitamins E and D in atopic dermatitis (eczema).

In 2011, a study [1] was performed with the aim of assessing the effects of the supplementation of vitamins D and E in patients with eczema. 45 patients with eczema were included in a randomized, double-blind, placebo-controlled, where each of them was subjected to a treatment with a duration of 60 days. The groups of patients that were supplemented with vitamin D were separated in groups and supplemented with vitamin E. In both cases there was a decline of approximately 35% in the intensity of eczema.

However, when the supplementation of vitamin E (600 IU) of vitamin D3 (1600 IU) was administered to all patients improved in 64%!!

The study revealed that there were significant effects and benefits of supplementation of vitamin D in patients with eczema and even more when administered in conjunction with vitamin E.

Eczema (atopic dermatitis) treated with vitamin D (1600 IU)

In December 2016 it was performed a scientific review [2], in order to compile results of several previous studies on vitamin D and eczema.

Were analyzed four randomized controlled trials, including the above mentioned, and it was discovered that the levels of vitamin D were generally lower in patients with eczema, especially in children. All the studies that were reviewed indicated that, in general, the vitamin D helped to improve the patient's eczema.

But what is the amount of vitamin D which should take?

Although many studies have shown that vitamin D may be beneficial in the treatment of eczema, another issue which can be put is whether the amount of vitamin D needed for a safe and effective treatment.

Before taking vitamin D it is important to bear in mind that, in the summer, your body is able to generate around 20 thousand units of vitamin D (day) Only with exposure to the sun.

However, during the winter months, it is difficult to generate a similar amount and much less than the recommended dosage.

Recommendations for the determination of vitamin D

Normally, the recommended dose is 16 IU of vitamin D per kg of body weight.

See the chart below for more information:

Age Dosage
Less than 5 35 units per kg per day
Between 5 – 10 2500 units per kg per day
Adults 4000-8000 units per kg per day

5000-10000 units per kg per day

Although these are general recommendations, the only reliable way to know the necessary amount of vitamin D is through blood tests.

Don't forget: Talk with your doctor before beginning any type of supplementation.
