3.  Like any vitamin, it’s a chemical that is needed by your body for good health. They are vital for everyone and
ensure that your body works well, is able to fight illness and heal well.
 Vitamin D has to be changed by your body a number of times before it can be used. Once it’s ready, your body uses it
to manage the amount of calcium in your blood, bones and gut and to help cells all over your body to communicate
properly.
 Vitamin D is very important for strong bones. Calcium and phosphorus are essential for developing the structure and
strength of your bones, and you need vitamin D to absorb these minerals. Even if you eat foods that contain a lot of
calcium and phosphorus, without enough vitamin D, you can’t absorb them into your body. Vitamin D is important for
general good health, and researchers now are discovering that vitamin D may be important for many other reasons
outside of good bone health. Some of the functions of the body that vitamin D helps with include:
 Immune system, which helps you to fight infection
 Muscle function
 Cardiovascular function, for a healthy heart and circulation
 Respiratory system –for healthy lungs and airways
 Brain development
 Anti-cancer effects

5.  Vitamin D isn’t like most other vitamins. Your
body can make its own vitamin D when you
expose your skin to sunlight. But your body
can’t make other vitamins. You need to get
other vitamins from the foods you eat. For
example, you need to get vitamin C from
fruits and vegetables.
 Getting the right amount of vitamin
D doesn’t depend on the foods you eat. To get
enough vitamin D you need to expose your
skin to sunlight regularly if not, address to
supplements. This makes getting the right
amount a little more complex compared to
other vitamins and minerals.
 Also what makes vitamin D unique compared
to other vitamins, is that when your body gets
its vitamin D, it turns vitamin D into a
hormone. This hormone is sometimes called
“activated vitamin D” or “calcitriol.”

6. Vitamin D mainly comes from your skin when it is exposed
to sunlight. After that, your body goes through a number of
chemical processes to change it so that your body can use it.
When your skin is exposed to the sun, it produces vitamin
D and sends it to your liver. If you take supplements or eat
foods that contain vitamin D, your gut also sends the
vitamin D to your liver. From here, your liver changes it to
a substance called 25(OH)D.
 This chemical is sent all over your body where different
tissues, including your kidney, turn it into activated
vitamin D. This activated vitamin D is now ready to
perform its duties. From here, it gets a little complicated,
but you can think of activated vitamin D working in two
ways:
 Manages calcium in your blood, bones and gut
 Helps cells all over your body to communicate properly
 As you can see, vitamin D goes a long way from its
original form from the skin, supplement or food. But
without vitamin D, your body can’t perform at its best.

7.  According toVitaminDCouncil.org: “Doctors are still
working to fully understand how vitamin D works within
your body and how it affects your overall health.”
 Evropi Theodoratou of the Centre for Population Health
Sciences at the University of Edinburgh in U.K and
colleagues reviewed more than 260 earlier studies which
include clinical trials and observational studies on the
potential health benefits of Vitamin D when consumed
from natural sources and taken as a supplement.
 The researchers found that of the 137 health benefits
associated with vitamin D, only 10 were based on
what they consider as rigorous trials and only one study which
links a child's birth weight to the vitamin D levels of the
mother during the third trimester of pregnancy showed
evidence of Vitamin D benefit which means that there
are hardly evidence to establish Vitamin D's role in the
outcomes.

8. Based on studies made by Stephen D.
Patterson and Richard A. Ferguson at
School of Sport, Exercise and Health
Sciences, Loughborough University,
Loughborough, Leicestershire,
Vitamin D isn’t really a vitamin, but
acts like a steroid hormone. Useful for
those wanting to hop the gain train.
It is a “secosteroid”, responsible to:
 Build muscle & strength
 Increase testosterone + dhea levels
 Pumping androgen receptor
sensitivity

9.  According to a study conducted at
Purdue University, a study was made
on rodents with a diet with no whey
protein, suboptimal calcium (0.25%),
and vitamin D (400 IU/kg), and
another group had a dietary whey
protein diet, high calcium, and high
vitamin D intake for 13 weeks.
 *drum roll*
 The results demonstrated there were
no consistent differences between both
groups, and the end result that both
groups had reduced accumulation of
body fat mass, and increased lean
mass!

10.  Cholecalciferol is a dietary
supplement that is used to treat
vitamin D deficiency. It is also used
with calcium to maintain bone
strength.
 Extra Virgin Olive Oil is used to
make your salads taste better.
 The rest are inactive ingredients.

11. They’re getting sued.

12.  Further studies are needed to clarify
the many gaps in knowledge and
elucidate the role of vitamin D in the
context of reproduction.
 Confirmation of experimental
observations relating to the risks of
Vitamin D would have important
public health implications.
 And these need to be done ASAP, so
that I can start looking at the guy on
the right 
