D3 The Sunshine Vitamin
The rays from the sun and your immune system work together to produce vitamin D3.
D3 is manufacture in your skin by the synthesis of UVB radiation and the cholesterol in your skin.
In this post, we take a closer look at the reasons why.
Below I have highlighted the important bits for you, just in case your schedule is tight.

There are two types of D Vitamins:
- Vitamin D2: abundant in fruit and vegetables.
- Vitamin D3: produced naturally with the help of the Sun or sourced from animals and dairy.
Being deficient in vitamin D3 can cause severe problems to your health, your development and overall well-being.
Most of Us Will Find That We Have Some Level of Vitamin D3 Deficiency
Correct amounts are regularly required to support, among other things, muscle function, bone and tooth development. It also enables your body to absorb calcium and phosphorus and has been linked to brain health.
Vitamin D3 is one of the vitamins we manufacture ourselves naturally; production begins when exposed to the sun.
The suns UVB rays interact with the lipids, otherwise known as cholesterol (fats) in the uppermost layer of your skin, to produce vitamin D3.
D3 is one of the essential vitamins your immune system needs to function effectively and efficiently.
However, there are significant drawbacks to getting the right amounts of vitamin D3 via the sunshine alone.
Does Skin Color Have An Impact On The Ability To Produce Vitamin D3 Using The Sun?
The biggest drawback to producing vitamin D3 with the help of the sun is skin tone.
Skin tone is usually darker in hotter climates because it contains a pigment called Melanin.
This pigment protects the skin from the damaging rays of the sun and gives skin its beautiful colour.
Melanin absorbs the suns ultraviolet rays that initiate vitamin D

synthesis and significantly inhibit the skins’ ability to produce the levels of vitamin D3 the body needs.
So even if you live in a country with wall to wall sunshine, it is still almost impossible for people with darker skin tones to produce sufficient daily amounts of vitamin D3 by the sun alone.
Skin colour bears no significance in countries that can go without sunshine for up to six months a year.
People who live in Northern Hemisphere, where in the winter the days become shorter and the nights longer, will also struggle to produce enough vitamin D3 naturally through sunlight alone.
Vitamin D2, on the other hand, is pretty easier to obtain from a wide variety of foods and dietary supplements.
Vitamin D3 comes from animals like oily fish, liver, egg yolks, butter and dietary supplements.
Make sure you include vitamin D3 rich food into your diet. However, this still may not be enough to ensure you are maintaining the correct levels.
A Word Of Warning (sunscreen is a must)
Please be mindful that wearing sunscreen is a must in the sun.
You also need to be aware that sunscreen blocks both the ultraviolet A (UVA) rays and ultraviolet B (UVB) rays from the sun.
It is the UVB energy that provides the energy your skin needs to make vitamin D3.
That UVB energy can burn the skin and cause cell damage that can lead to cancer.
UVA energy contributes to skin damage and also causes premature ageing. Sun protection needs to be worn at all times whilst out in the sun, no matter what your skin tone.
