|Why do we need Vitamin D?|
Vitamin D is a necessary vitamin for the
absorption of our bodies of minerals such as
calcium, iron, magnesium, phosphate and zinc.
Thus, your body is able to utilize these minerals
to keep your body healthy and working properly.
This is why some milk includes added vitamin D,
which is added to enhance calcium absorption in
the body. I hope this explanation was useful!
We use it to control the amount of calcium
dissolved in our blood. We need dissolved calcium
in order for our nerves and our cells to work, but
too much would be poisonous.
The most interesting part of vitamins is
that they are needed and also cannot be produced
by your body on its own. This means that
without an external source of vitamin D (including
the sun), you couldn't make it. Vitamin D
specifically is needed for healthy bones,
since it plays an important role in how your body
uses calcium. There are quite a few diseases
(rickets, stunted growth, etc.) if one doesn't get
enough vitamin D. In general, the best way to
get vitamin D is from the sun: getting a
little bit of UV rays from the sun allows your
skin to make some vitamin D on it's own, and helps
keep you healthy.
