Product description

What is vitamin D?

D-Day® long contains vitamin D, a nutrient that is essential for metabolism and has a wide range of functions.

Vitamin D is involved in the absorption and utilization of calcium and phosphorus from food and in the maintenance of bones and teeth. But muscles and our immune system also need vitamin D to function.

The most important form of vitamin D is vitamin D3. The human body can even produce this substance itself. However, this only works with sufficient sunlight and also depends on where you live.

In the winter months, sunlight is usually not sufficient due to the low position of the sun. Studies show that up to two thirds of the population do not get enough vitamin D.

And even in summer, the use of sunscreen, for example, often leads to the body's own vitamin D production being insufficient.

By the way: tanning salons are not an alternative, because the necessary UV-B radiation is filtered out there because it is associated with risks for the skin.

If vitamin D is not produced through sunlight, then professional associations recommend taking in 20 µg of the vitamin daily. A normal diet only makes a small contribution to vitamin D supply.

Because the vitamin is only found in a few foods (mainly salmon, trout, herring, eel and mushrooms), only about 10% of the requirement is normally covered by food. Food supplements can close this intake gap.

What is special about D-Day® long?

There are many vitamin D preparations. Normally, these must be taken every day to ensure a regular intake.

D-Day® long, an innovation from T&D Pharma, is different: one of the easy-to-swallow capsules contains 140 µg (5600 IU) of vitamin D3 and covers the requirement for a whole week. It is best to take the capsules at the same time every day, e.g. on Sundays for breakfast.
