10 Best Vitamin D Supplements UK 2024 | Holland and Barrett, Boots, and More

This supplement from UK brand Nutravita is free from almost every potential allergen, as well as free from GMOs and artificial colours and flavours. The soft capsules are the size of a small pea and coated in a smooth gel so are easy to swallow.

This particular bottle contains an entire year’s worth of servings, and at just under fifteen quid, that’s a real bargain when compared with other options on the market. The formula contains D3 which is the most effective at raising your vitamin D levels, so you’re in good hands. 

The bottle of vitamin D capsules from Nu U contains a full 365 days of vitamin D3 to see you through an entire year – this is great if you don’t get outside much during both the summer and winter months.

The soft gel capsules are easy to swallow, contain just over the daily recommended amount of vitamin D and are free from any artificial ingredients, soya, nuts, gluten or GMO’s amongst a whole list of other allergens. The shell of the capsules does, however, contain gelatine so they are not suitable for vegetarians. 

Holland and Barrett are one of the leading companies for vitamins and supplements in the UK. As such, they have a wide range of vitamin D supplements to choose from, varying in dosages, forms, and sizes of container. 

Our pick has the recommended dosage of 10 mcg and comes in a pack of 100 pills, which will last you just over three months. They also do the same product in a larger size of 250 tablets which will last you the whole of the dark side of the year. The pills are compact and flat, so they aren’t too difficult to swallow.

If you’re looking for the cheap and cheerful option and you’re not that fussy, Boots own brand is an excellent option. It provides the exact recommended dosage from the government of 10 mcg per tablet. 

Even as a tablet, these are relatively easy to swallow as they are compact, small, and flat. 90 tablets provide you with a 3-month supply, which may not be as much as some of the other options on the list, but at the tiny cost of just over 2 quid a bottle, you can't complain.

If tablets and capsules just don’t work for you, try an oral spray. This one from Better You is one of the most popular vitamin D products on Amazon. In just a tiny 15ml bottle, there are 100 doses of vitamin D. It is also suitable for vegetarians.

The dosage is higher than the minimum recommended amount, but it’s nowhere near the danger zone of 1000 mcg per day. Simply spray one spritz onto the inside of the soft tissue on your cheek per day and this bottle will last you just over 3 months. It also has a refreshing natural peppermint flavour!

Unfortunately, many vegan options for vitamin D are of the D2 variety, which is less effective at raising your vitamin D levels. But, these supplements from Igennus contain D3 and are suitable for vegans! These clever clogs' have found a way to extract D3 from plant sources such as fungi. Win-win!

The vitamins come in tablet form which some people struggle to swallow, however, these are small, round, and easy to slip down. The bottle contains a year’s worth of supplements at an excellent price point.

Vitabiotics are one of the UK’s leading brands of vitamin D with over six and a half thousand reviews on Amazon! The packet contains 96 tablets – just over three month’s supply – at a very reasonable price of under five pounds a pop. 

These tablets should be swallowed whole with a meal. The tablets are very small, about the size of a pea, so are easy to swallow, but as the D3 is derived from sheep's wool it isn't suitable for vegans.

If you have difficulty swallowing tablets but aren’t interested in effervescent or oral sprays, this product from Solgar could be the one for you. Providing 25 mcg of vitamin D, this is a little above the recommended amount by the government, but it's still far away from the daily maximum. 

These are soft gel capsules which are easy to swallow and are free of any sugars, starch, salt, and a range of allergens. These capsules have raving reviews and are highly recommended by most that try them. The one major downside is that they contain palm oil. 

The mixed berry flavoured effervescent vitamin D supplements from VOOST are great if you prefer to take your vitamins as a drink. The flavour is sweet without containing any sugar and they’re easy to digest when dissolved quickly in 200 ml of water.

The pack contains 10 tabs of 25 mcg, so one pack will last you just over a week, however, when bought on Amazon, they come as packs of 6. VOOST tablets are gluten-free but may contain other additives and preservatives. Unfortunately, there is no way to tell whether these are D2 or D3. 

This small bottle contains almost a year's worth of tablets, at the super-strength of 2000 IU – that’s 50 mcg. This is much more than the recommended daily amount, so this option may not be suitable unless your doctor has advised of a deficiency. 

That said, these tablets are completely free from yeast, fish, wheat and are suitable for vegetarians and vegans as vitamin D2 is derived from plant matter, specifically beet. However, as we know, D2 may not be as effective as D3 according to some scientists and researchers.
