Unlike other vitamins, vitamin D functions like a hormone, and every single cell in your body has a receptor for it.
Vitamin D helps
your body absorb calcium. Calcium is one of the main building blocks of bone. It also has a role in your nervous, muscle, and immune systems.
Vitamin D
deficiency is very common. It’s estimated that about 1 billion people worldwide
have low levels of the vitamin in their blood.
Who is at risk of
vitamin D deficiency?
1- People with dark skin
2- Older adults
3- People who have obesity
4- People with chronic
kidney or liver disease.
5- Breastfed infants

5 proven signs that you have vitamin D deficiency
1- Low mood
The so-called
happy hormone (serotonin) falls with lack of sun exposure. Our bodies need
vitamin D to activate to effectively make serotonin in the brain. If you feel
low or irritable, it could be a sign that you are deficient in vitamin D.
2- Getting sick
often
If you seem to
catch every cold going around and get sick a lot, it may be down to low levels
of vitamin D. This is because vitamin D is essential for keeping your immune
system strong and healthy. It is recommended that everybody starts to
supplement vitamin D in the early autumn to make sure they have enough vitamin
D in the winter.
3- Fatigue
People who are
tired all the time, especially older adults, may not suspect a vitamin D
deficiency could be draining their energy. Increasing vitamin D levels have
been seen to improve signs of fatigue.
4- Achy bones and
joints
Vitamin D
deficiency affects bone health, which could result in a throbbing or achy
feeling in your bones. This is often most noticeable in the knees and back.
Those who do not have enough of this important vitamin may be at more risk of
fractures.
5- Head sweats
A common sign of vitamin D deficiency is a sweaty scalp (this is one reason new born babies are monitored for head sweats). A sweaty scalp could be an early sign of vitamin D deficiency.

serving. Liver and pastured egg yolk have a tiny bit – 40 i.u. in 1 egg or 3
ounces liver. That’s a lot of liver, eggs and canned fish to get a dose of 1000
to 7,000 i.u. daily.
