What Is Vitamin D and Why Do We Need It?
Often called the sunshine vitamin, vitamin D is a fat-soluble nutrient that plays a vital role in keeping our bodies functioning well. Unlike most vitamins, our bodies can actually produce vitamin D when our skin is exposed to sunlight — specifically UVB rays. However, living in the UK means that for a significant part of the year, we simply don't get enough sun to maintain healthy levels.
Vitamin D supports a surprisingly wide range of functions in the body, from bone strength and immune health to mood regulation and energy levels. It's also increasingly being discussed in relation to skin health, which is why we're seeing so much interest in it from our clients here at the clinic.
Why Are So Many of Us Deficient?
According to the NHS, around one in five people in the UK has low vitamin D levels. This is largely down to our geography and lifestyle. Between October and March, the sun in the UK isn't strong enough to trigger vitamin D production in the skin, no matter how much time you spend outdoors.
Other factors that can contribute to low levels include:
- Spending most of the day indoors
- Regularly using high-factor sun cream (important for skin protection, but it does reduce vitamin D synthesis)
- Having darker skin, which requires more sun exposure to produce the same amount of vitamin D
- Being over the age of 65
- Following a diet low in vitamin D-rich foods
Signs Your Vitamin D Levels Might Be Low
Low vitamin D can sometimes be easy to overlook, as symptoms tend to be gradual and non-specific. Some people notice things like persistent tiredness, low mood, muscle weakness, or a general sense of not feeling their best. Skin concerns such as dullness and a lacklustre complexion are also commonly reported by those with low levels, though it's important to note that these symptoms can have many causes.
If you're concerned about your vitamin D levels, we always recommend speaking with your GP, who can arrange a blood test to give you a clear picture.
Vitamin D and Your Skin
There's growing interest in the role vitamin D plays in skin health. It is thought to support the skin's barrier function and may have a part to play in overall skin resilience and appearance. A well-nourished body tends to reflect that from the inside out — and this is something we talk about regularly with our clients as part of a holistic approach to aesthetics.
Getting Your Levels Up
The NHS recommends that adults consider taking a daily supplement of 10 micrograms (400 IU) of vitamin D throughout autumn and winter. You can also support your levels through diet by including foods such as:
- Oily fish (such as salmon, mackerel, and sardines)
- Eggs
- Fortified foods like certain breakfast cereals and plant-based milks
