Vitamin D is crucial to our bodies. Aside from giving our immune system a boost, it also helps regulate the amount of phosphate and calcium. Our bodies create vitamin D when we're outdoors, and we have direct sunlight on our skin.

However, with the lack of sunlight we experience in the winter months, getting the right amount of vitamin D can be a bit challenging.

If you're wondering how much we should get per day, the NHS recommends that you get a minimum of "10 micrograms of Vitamin D per day" (400 IU) as this helps us maintain healthy muscles and bones.

Similarly to multivitamins, there are several types of vitamin D supplements - capsules, effervescent tablets and even liquids. Finding the best for you will depend on your preferences, but don't worry, our best vitamin D supplement guide has included them all.

And if you have any burning questions in terms of all of this, make sure you check out our vitamin D FAQs section at the bottom of this article.

Best vitamin D supplement overall

Vitamin D3 + K2 (MK-7) Liquid Drops with MCT Oil
Price: £22.99

We absolutely love this product! Aside from getting a large dose of vitamin D - each liquid drop contains 1,400 IU of Vitamin D3 and 25mcg of Vitamin K. It also has MCT oil, which has plenty of added benefits. Another perk is that it tastes like peppermint, and it doesn't have any added fillers.

Best vitamin D tablet for exact intake

Holland & Barrett Vitamin D3, 10ug
Price: £49.99

If you prefer capsules, then the Holland & Barrett Vitamin D3 capsules might just be the one for you. It's easy to see why it's Amazon's choice: for just under £5, you're getting 100 tablets. Each tablet has 400 IU, which is the exact recommended daily amount of vitamin D, so just one of these jars will keep you covered for 100 days.

Best value for price

It's easy to see why this product has made our best vitamin D supplement roundup. Aside from each supplement being a tiny 6mm micro tablet - which is great for anyone who doesn't like taking tablets - each capsule has 1000 IU. Did we mention that the packaging is also environmentally friendly?

Best vitamin D tablet for dietary requirements

Solgar Vitamin D3 (Cholecalciferol) 600 IU
Price: £11.19

Another excellent option is the Solgar Vitamin D3 tablets, particularly for those who may have certain dietary requirements. Whilst this product doesn't meet all dietary needs, it is vegetarian, kosher and halal - it's also free from sugar, starch and salt. Each capsule contains 600 IU.

Best effective vitamin D supplement

Health Hi-Po Emulsi-D3
Price: £30.99

If you're looking for a pretty high dose of vitamin D, then these tablets have got you covered. It comes in liquid form, so it's really easy to take, whether you're adding a few drops on your tongue or to your drink. Because this product is so high in strength (each drop has 2,000 IU of vitamin D), make sure you discuss your required dosage with a doctor first.

Best vitamin D effervescent tablets

If you're looking for effervescent tablets, then these are one of the best you can buy. Each tablet has 1000 IU of vitamin D. We also love that it has a mixed berry flavour, so if you're not a fan of flavourless or bitter-tasting capsules or tablets, this is an excellent choice.

FAQs:

Are vitamin D supplements safe?

As long as you are taking the correct dose you require and are not taking too much, then yes, vitamin D supplements are safe. If you think you have a vitamin D deficiency, please consult your doctor so they can prescribe you your required dose.

If you want to get vitamin D naturally, there are a couple of foods that have high levels of it. These include oily fish such as salmon and sardines, red meat, egg yolks and fortified foods.

When should I take vitamin D supplements?

It is usually better to take vitamin D tablets in the morning.

How much vitamin D is too much?

The daily recommended amount of vitamin D is 10mg or 400 IU. This is for people who have normal vitamin D levels and don't have a vitamin D deficiency. The NHS recommends that you do not take more than 100mg or 4000 IU a day. If you want to take more or less than the approved dose, make sure you speak to a doctor first.

Do I need vitamin D supplements?

Most people will not need a supplement as they can get all the required vitamins and minerals by eating a healthy diet. However, there are several reasons why you may not be getting the correct amount of vitamin D. If this is the case and you do have a vitamin D deficiency, then it is recommended that you take a vitamin D supplement.
