What Are Good Sources of Vitamin D?


Of all the vitamins, vitamin D is perhaps the easiest one to take for granted. Its benefits are, of course, vital – it maintains teeth and bones* and plays an important role in the immune system** – yet when one of the sources of vitamin D is sunlight, we don’t always need to make an effort to get enough. But what if you’re not able to spend much time outside, and what happens when the summer is over?

Luckily, finding sources of vitamin D in food isn’t all that hard. We’ve compiled a handy list of vitamin D sources below, so you don’t have to worry when autumn (always particularly eager) comes along. 

Good sources of vitamin D

There are plenty of natural sources of vitamin D, but a couple of the products you’ll find in this list are also fortified, which means that vitamin D has been added to them to make it easier to get the right amount. Ready? Let’s go. 

  • Salmon. Along with the other three fish in this list, salmon is what is known as an ‘oily fish’: a name for a few (very delicious) fish families that are sources of ‘good’ unsaturated fats***. The NHS recommends eating one portion of oily fish a week – make it a 85g salmon fillet, and you’ll get 6.2µg vitamin D, over half of the recommended daily intake. In need of recipe inspiration?

  • ProActiv EXPERT with vitamin D. Delicious on your morning toast or melted over vegetables, our new ProActiv EXPERT spread contains 2µg of added vitamin D per serving****. 
  • Egg yolk. Good news: one large, raw egg yolk contains 2.3μg of vitamin D, which means your beloved morning eggs, whether poached or boiled, are good for about a tenth of your RDA. 
  • Tuna. Fresh tuna is a good source of vitamin D too, with 3.8µg per 120g (typical tuna steak size) . Lovers of tinned tuna will be sorry to hear that (being less fresh), this isn’t quite as good a source 0.55ug per portion (50g). Not sure how to cook fresh tuna at home?

  • Trout. Yes, more fish! Trout fillet contains 8.5g vitamin D per 120g fillet. We recommend trying it baked with flaked almonds.
  • Mackerel. This rich fish packs a powerful favour punch, offers 9.5µg per 112g fillet, and is incredibly tasty when barbecued. Find our recipe (with lemony garlic potatoes and fresh samphire) here

And there you have it! Six delicious foods that can all be considered dietary sources of vitamin D.  Adding these to your diet will contribute to keeping your vitamin D levels up during the cold winter months. That said, getting enough vitamin D by consuming these foods alone can be difficult, which is why the NHS recommends everyone to take daily supplements containing 10mcg of vitamin D during the autumn and winter months.
