Many people take vitamin D supplements in the fall and winter. They do this because we consume less vitamin D in the fall and winter. How does that work exactly? How do you get vitamin D, and what does it do for your body? What causes a vitamin D deficiency, and what are the symptoms? Read all about that and more in this blog post!

Why Vitamin D is so important

You probably know that vitamin D is good for your bones and teeth. But there's so much more.

Vitamin D also helps keep your muscles supple and supports your immune system. This is helpful if you seem to catch every little virus.

It also ensures that calcium is properly absorbed. For this reason, it's an important vitamin for our bodies, working in several areas.

How do you get vitamin D?

The greatest source of vitamin D is the sun. Sunlight helps your skin produce vitamin D.

Besides sunlight, animal-based foods are also a source of vitamin D. Meat and eggs contain vitamin D, among other things. Vitamin D is also found in oily fish, such as herring, salmon, and mackerel.

Below you will find a detailed list of some products that contain vitamin D:

  • Fatty fish such as salmon, herring, mackerel and eel

  • Cod liver

  • Beef or calf liver

  • Eggs

But let's be honest: even if you eat fish every day, it's difficult to get enough vitamin D through food alone. If you eat a plant-based diet, it's even harder.

How do you know if you have a vitamin D deficiency?

A vitamin D deficiency is not always immediately noticeable; it can creep in a bit.

Because vitamin D is involved in many processes in the body, it can manifest itself in various ways. Below are some symptoms:

  • Fatigue or low energy
  • Reduced resistance
  • Bleeding gums
  • Muscle cramps or muscle pain
  • Painful joints
  • 'Weaker' bones, rapid bone fractures

More and more studies also point to the connection between low vitamin D status and autoimmune diseases.

Causes of vitamin D deficiency

Elderly people (60+) and people with dark skin need more minutes of sun per day, but people who eat a plant-based diet also get less vitamin D.

As mentioned, sunlight is the greatest source of vitamin D. The human body therefore obtains most of its vitamin D from sunlight, but unfortunately, in autumn and winter, it's not possible to get enough vitamin D from sunlight because the sun shines less brightly and for shorter periods.

In addition, we spend less time outdoors in winter compared to spring and summer, which increases the risk of vitamin D deficiency.

For this reason, a vitamin D supplement is often recommended (especially in autumn and winter).

Conclusion:

Get as much sun as possible on your face on gray days, or supplement with supplements. Avoid vitamin D deficiency and live a healthy and energetic life.
