Vitamin D Foods that can boost your immune system during Winter

Experts Recommend we Take more Vitamin D this Winter

With the UK Government requesting guidance on the use of Vitamin D throughout the COVID-19 pandemic, and many arguing both for and against the connection between the two.

Many experts, however, are reiterating the point that Vitamin D plays a crucial role in our health during the Winter period regardless of COVID-19 and should always be maintained as such.

What Happens if Your Vitamin D is Too Low?

Lacking a healthy amount of Vitamin D in your diet can lead to a few, not so serious health issues including fatigue, weakness and mood swings. These are usually not serious symptoms but can become more complex and problematic if you have Vitamin D deficiency.

The Best Food Sources of Vitamin D

While the most natural and convenient (mostly) source of Vitamin D being exposure to sunlight, there are plenty of other ways, particularly during dark winter months, or a global pandemic perhaps, where eating the right foods can be a great alternative.

Fish & Oils 

Fish is by far the best food option for Vitamin D, with things like Salmon, Cod, Mackerel and Tuna all being fantastic sources of Vitamin D, along with products like Cod Liver Oil and Omega 3 fish oil also offering the same, if not more, health benefits in a more convenient manner.

Dairy: Milk & Eggs 

Surprisingly, dairy products like milk, cheese, and eggs also contain a healthy amount of Vitamin D, including health food alternatives like Puro Organic Coconut Milk, however, you would need to eat a considerable (and unhealthy) amount of dairy in your day-to-day life.


Mushrooms also provide a delicious dose of Vitamin D in the form of an incredibly popular ingredient and tasty snack, with the best of the bunch being Shiitake Mushrooms. Providing an incredibly versatile way to make sure you maintain a healthy level of Vitamin D.
