Boosting Vitamin D in Winter: Best Fruits for Energy & Focus

Did you know the Government advises everyone to consider taking a daily vitamin D supplement during the autumn and winter?

When your work Winter hours start and end in complete darkness, your vitamin D levels can take a serious dip. Often called the sunshine vitamin, vitamin D plays a big role in keeping us healthy, happy, and productive, especially important in these darker months!

During the summer, our bodies make vitamin D naturally from sunlight hitting our skin. But from October to March in the UK, UV levels are too low for most people to produce enough, particularly for those working indoors all day…

Signs of low vitamin D levels:

That’s why eating adding vitamin D-rich fruits and supportive nutrients (like magnesium and vitamin C)  can make a real difference!

Fruits that help you get (or absorb) more vitamin D:

While some fruits naturally contain high amounts of vitamin D, several are rich in nutrients that support vitamin D absorption, such as magnesium and vitamin C. These fruits make excellent additions to your health:

What vitamin D does for the body:

Think of vitamin D as the quiet multitasker of your health. It:

  • Regulates calcium and phosphate for strong bones and teeth!

  • Supports the immune system, helping fight off winter colds & flu

  • Contributes to mental wellbeing, reducing feelings of fatigue or low mood

  • Aids muscle recovery, perfect for those gymming-it, or suffering with desk fatigue

How much vitamin D do you need each day?

According to the NHS, adults need about 10 micrograms (400 IU) of vitamin D per day. While sunlight remains the best natural source, foods and fortified options can help top up levels, especially when paired with magnesium- and vitamin C-rich fruits.

Encouraging your office team to snack smarter this winter can go a long way. A bowl of mixed fruit, a few bananas, or a daily glass of juice can help everyone feel brighter, more focused, and ready to take on the day.

Brighten up your office with a vitamin D boost this Winter!

When winter dulls the sunlight, bring the brightness indoors.
Adding vitamin D-supporting fruits to your monthly office fruit box is a simple, delicious way to help your team stay healthy and motivated!

Because when your people feel their best, your workplace shines too!
