Often called the "sunshine vitamin", Vitamin D plays a crucial role in immune function throughout the year. You would have thought that during the sunnier months, the levels of Vitamin D we acquire would mitigate themselves... but this couldn't be further from the truth!
In the UK, the sun is only strong enough to meet our Vitamin D needs from April to September, meaning throughout the winter, the levels of Vitamin D support we should be seeking is much higher than in the summer months.
On top of this, we should be consuming the "sunshine vitamin" within our balanced and nutritious diets. However, food sources alone rarely give you enough Vitamin D to meet your daily needs. It is advised that the average Brit should consider taking a daily supplement containing 10μg of Vitamin D to help maintain a healthy, thriving immune system.
