Vitamin D To Strengthen Your Body This Winter

Many young people have a deficit of Vitamin D because they spend less time outdoors in the winter and do not have a balanced diet.

Throughout your life, bones need to form, regenerate, and stay healthy. Vitamin D makes this possible by helping proper calcium absorption from your diet.

In addition to with calcium absorption, vitamin D has many other benefits:

  • Muscle contractions: Vitamin D also helps muscle function and prevents involuntary muscle contractions that can cause falls or tremors.
  • Regulation of the immune system: vitamin D is one of the vitamins that helps improve our defenses to protect us against possible pathogens and infectious diseases.

Sun exposure, our greatest source of vitamin D

Vitamin D is largely obtained from direct sun exposure. Without being exposed to the sun excessively, ultraviolet radiation, in small amounts helps our body produce vitamin D.

In summer, with proper skin protection, it is easy to obtain vitamin D naturally. But what about in winter? During the coldest season of the year, in which we have fewer hours of sun we have reduced opportunity to generate vitamin D naturally. This lack of vitamin D hinders the immune system, which can cause low defenses and increase the chances of getting sick.

If in winter we do not get enough vitamin D from sun exposure, how do we get it? There are foods that we can include in our diet that are rich in this vitamin. Some of these are egg yolks, fatty fish (such as tuna, salmon or mackerel) and some milk or fruit juices that are usually enriched with vitamin C and D.

However, at this time of year, adding a vitamin supplement containing vitamin D to our diet can help support healthy vitamin D levels and thus help us to cope with winter in the best possible way.
