Why doesn't Zinoshine+ contain more Vitamin D per tablet?

Each tablet contains 12.5 mcg Vitamin D.
Other products might have more, like 50 or 100.

The reason why we don´t have such high content is because we first measure the level of Vitamin D that you have, then we want a tailored tablet where you can achieve an optimal level. Thus, we do not have too high content because you might get more Vitamin D than necessary.
