Why are summer and sunshine periods and triggers for this vitamin D?
Vitamin D has two origins:
– vitamin D2 (ergocalciferol), produced by plants
– vitamin D3 of animal origin (cholecalciferol).
The human body transforms vitamin D2 in vitamin D3. Vitamin D can be extracted from lanolin, which comes from sheep’s wool. It can also be found in plant form, from yeast exposed to ultraviolet light.
We can synthesize vitamin D at the epidermal level by acting UVB. This fusion is mainly done from April to September (in France), the months with the most sunshine. Theoretically 15-20 minutesSun exposure in summer it is enough to meet 70% of needs.
Attention however, vitamin D is stored in adipose tissue, liver, and muscle. Like other vitamins, it is not easily eliminated. Therefore, the exposure should not be too high, so it is always necessary to protect yourself (hat, sunscreen).
Are all skin types the same when it comes to vitamin D? ? Why?
Not all skins are is not equal against vitamin D. For example, fair-skinned people tend to use less light to avoid sunburn. Therefore, we can notice the lack of these people. People with pale or dark skin need more sunlight to produce the same dose of vitamin D.
We usually give a addition children under 2 years old and the elderly. Indeed, their effect is usually less, but vitamin D is essential for their development/maintenance skeletal system.
In any case, it is necessary consult a professional determine the need for replenishment.
How should we consume it so that our skin can benefit from the benefits of vitamin D?
The vitamin D deficiency is very common. According to studies, almost 80% of French would be affected by marginal rates or a more open deficiency, with significant differences depending on more or less sunny regions. The pollution atmosphere would be one of the main reasons explaining insufficient vitamin D levels in France.
The diet is also lacking in foods rich in vitamin D. It is often easier to have in stock food supplements. You can also expose your forearms to the sun for 15-20 minutes a day. In any case, it is necessary to consult a specialist to determine possible supplementation needs.
