There is overwhelming current scientific evidence that calls us to talk about this topic. The modern human being, covered with clothes, hats and sunglasses, produces little or nothing of Vitamin D. Let's review together what this vitamin is and how to optimize its positive effects.
Via Truth In Supplements
Vitamin D is a type of chemical that the surface of the skin produces when it comes into contact with the sun's rays , specifically UVB rays. People who live in the middle latitudes of the Earth, with darker skin or older adults, will have less capacity to produce it.
We can obtain it from food sources and here we must bear in mind that there are 2 types of Vitamin D: vitamin D2 (ergocalciferol) found in vegetables and mushrooms, and Vitamin D3 (cholecalciferol) which is what is actually produced in the skin. The latter is also found in fatty fish and animal liver; also in eggs and milk or fortified flours but in less quantity.
However, it's not just a vitamin, it's actually a hormone . In other words, it fulfills multiple biological functions: regulate calcium and phosphorus in the bones, allow good muscle health, promote normal nerve impulses, regulate the immune system (of defenses) and keep the intestines vital with their associated bacterial flora. Even adequate levels link it to a decreased risk of dying from any cause.
As human beings, until not a few thousand years ago, we were used to running almost naked through the Amazon jungles or African deserts. Here hormone D was not a problem. However, we covered ourselves more and more, due to cold, lifestyle or fashion.

Due to the above, today we face the problematic situation described above. The increase in irritable colon, allergic and autoimmune diseases, breast and colon cancer, or low bone density, would be closely linked to the lack of Vitamin D. Or the other way around? Studies also suggest that low levels of this vitamin could be a consequence of being sick, rather than the cause itself . And we know that almost all diseases in the modern world are linked to the way we currently eat poorly. So, what to do so that we don't miss it?
More than a vitamin, an important hormone. Just as thyroid hormone is supplemented in hypothyroidism, “hormone D” should also be taken into consideration .
We are not vampires , but the atmosphere has been greatly damaged by us. We can no longer walk naked in the sun, running all day with exposed skin as our ancestors did. Select when to expose yourself to the sun and use sunscreen if you will be exposed for more than 30 minutes, so you take advantage of the summer sun.
