Vitamin D is one many fat-soluble vitamins that the body requires to function correctly. We make this essential vitamin from the skin's unprotected exposure to sunlight, but it can also be found in certain foods such as eggs, cereal and fatty fish.
Despite being vital for healthy bones and a robust immune system, our more sedentary lifestyles have meant that exposure to the sun has dropped dramatically and our processed and specialist diets has meant that supplementation is needed to maintain a healthy level of vitamin D.
Vitamin D is responsible for a number of functions within the body. It helps regulate calcium, ensuring it enters the bone to maintain healthy bones and teeth. It supports a healthy immune system, protecting the body from illnesses such as the common cold and plays a fundamental role in ensuring normal muscle function.
It comes in two major forms, D2 and D3. While both forms can be processed by the body, vitamin D3 occurs naturally within humans and is generally considered the preferred form of supplementation.
It is naturally found in a number of animal products as well as some fortified foods. Including:

Vitamin D deficiency remains a worldwide issue with around 1 billion people across the globe experiencing inadequate levels. The National Institute for Health and Care Excellence (NICE) estimate that vitamin D deficiency in the UK affects one in five adults and one in six children – that’s 10 million of us!
Signs of vitamin D deficiency can manifest in common health conditions such as frequent coughs and colds, tiredness and fatigue, low mood, achy muscles and poor bone and tooth health. So, it’s easy to see why we all need it.
If you suffer from any of these symptoms regularly, it could be a sign that you’re lacking in vitamin D!
Factors affecting vitamin D absorption
We get the majority of this vital vitamin from exposure of our skin to sunlight. The sun’s ultraviolet B rays (UVB) are absorbed by cholesterol in the skin and is then synthesised into vitamin D.
However, in the UK the UVB rays are only strong enough between April and September for vitamin D production, meaning for large parts of the year, vitamin D production from the sun is impossible.
Couple this with the UK’s notoriously cloudy climate, UVB rays being blocked by sun creams and our ever increasing indoor existence. You can see why this is becoming an increasing issue.

Although everyone should consider a vitamin D supplement during the winter months, The Department of Health recommends that the following ‘at risk groups’ take a vitamin D supplement all year round.
All pregnant and breastfeeding women
Infants and young children under 5 years of age
Older people aged 65 years and over
People who have low or no exposure to the sun
People who have darker skin
Signs of vitamin D deficiency can manifest in common health conditions such as frequent coughs and colds, low mood and tiredness and fatigue.
Public Health England recommendeds that everyone living in the UK should take a vitamin D supplement from October to April.
