This year, summer has been very kind to us and has spoiled us with plenty of sunshine and hot temperatures. Have you been able to really enjoy the sun yet?

You probably already know that our Body can produce vitamin D3 in the skin under sunlight. Convenient, right? It's free and doesn't require any effort, you just have to go out!

Vitamin D is a true all-rounder, which is absolutely essential for our immune system, healthy bones, good muscle function and many other processes in the body.

However, it is not quite as easy as you might imagine, because…

…according to various studies, most people in Germany are under-suppliedAlthough the results vary between individual studies, it is consistently shown that 60-90% of the German population is undersupplied.

Undersupply in the case of the studies means that the amount Vitamin D in the blood is below 20 nanograms per milliliter – even in summer!

But if we can produce vitamin D through our skin, why are so many people undersupplied even in summer? From April to September, the sun should really boost vitamin D production in the skin, right?

In theory, yes. In practice, it's not so easy, even in summer. Most people still don't go out into the direct sun enough in summer and usually use far too much sunscreen! The use of sunscreen then prevents vitamin D3 synthesis.

But that's not allThe skin's ability to produce vitamin D also decreases with age. Older people therefore often suffer from vitamin D deficiency, even in summer.

Other risk factors for vitamin D3 deficiency that may apply to you:

• They work mainly indoors
• You are chronically ill
• They mainly wear long clothes even in summer
• You have dark skin
• You are in need of care
• You are overweight

So should you take a vitamin D supplement in summer too?

Yes! Especially if you fall into one or more risk groups, additional supplementation is important.

If you feel unsure, a blood test at your family doctor can also provide information about your vitamin D levels. Unfortunately, you still have to pay for such a blood test yourself, even though deficiency is so widespread in Germany.

Since vitamin D3 “works together” synergistically with vitamin K2, this vitamin is in our product naturally contained.

Whether in summer or winter, if you want to maintain your vitamin D levels, our Vitamin D3 + K2 from HS Activa is ideal.

Extra tip for natural sun protection: Coconut oil, along with olive oil, is one of the best oils that can be used for natural sun protection (SPF 8). Coconut oil also has a very pleasant smell and gives the skin a beautiful shine.

Enjoy the summer!
