Why you can trust Good Food reviews
When reviewing vitamin D supplements, we combined editorial independence with expert guidance. Our health editor led the review process, working alongside a freelance nutritionist to make sure every product was judged against both practical and scientific standards.
- Expert insight: our nutritionist advised on dosage, formulations and safety, helping us identify which products met evidence-based recommendations.
- Real-life focus: our health editor considered how easy each supplement was to take, whether in tablet, capsule, spray or gummy form and whether the cost felt justified.
- Independence: as always, findings were not shared with manufacturers or retailers before publication, and we don’t accept payment for coverage.
This guide blends expert nutritional advice with everyday usability, so you can choose vitamin D supplements with confidence.
How we tested vitamin D supplements
All vitamin D supplements were tested within the same review period, so results could be compared fairly. Each product was tried and assessed against our set criteria, with detailed notes recorded during the process. We included a broad mix of brands and formats, from tablets and capsules to gummies, sprays and liquids, at a range of price points to reflect different budgets.
We focused on the following areas:
- Taste and flavour: for products that were flavoured or chewable (such as gummies, liquids or sprays), we noted whether they were enjoyable to take daily, or if they left an aftertaste.
- Nutrient profile: each supplement was checked for the amount of vitamin D provided per daily dose, and compared against the Nutrient Reference Value (NRV). We also considered whether the dosage suited different needs, from everyday maintenance to higher support levels.
- Additives: we reviewed ingredient lists to see if supplements contained extras such as preservatives, artificial sweeteners or colourings, highlighting products with a simpler, cleaner formulation.
- Dietary requirements: suitability for different diets was factored in, including whether products were vegetarian, vegan or free from common allergens.
- Value for money: we compared the cost per day against quality, formulation and ease of use, weighing up whether a supplement offered good value compared with similar products on the market.

At the a maximum dose of 100mcg (2000% NRV) vitamin D3, it’s combined with sunflower oil for better absorption, but not vitamin K. The capsule shell contains gelatin so these aren’t vegetarian, although they are gluten- and lactose-free. The huge pack of 425 one-a-day softgels offers excellent value. This product is best suited to those who have had their vitamin D levels checked and as a result have been advised to supplement at a higher dose.
Available from:
JS Health Vegan Vitamin D
Available from Amazon (£19.99), JS Health (£19.99)

Available from:
Zooki vitamin D3+K2
Available from QVC (£19.80), Healf (£19.49)
Price per day (recommended dose): 83p
Star rating: 4/5
The manufacturer claims that ‘liposomal technology’ increases absorption, although you might still want to take it with a high-fat food to ensure maximum absorption. These contain a generous 75mcg (1500% NRV) of vitamin D3 along with vitamin K (avoid if you’re on blood thinners). Suitable for vegans and those on a gluten-free diet.
Available from:
Vitl Vitamin D3
Available from Vitl (£5.95)
Price per day (recommended dose): 17p
Star rating: 4/5
An optimum serving of vitamin D. Supplying 25mcg (500% NRV) of vitamin D3, these vegan softgels contain sunflower oil to help you absorb more vitamin D. They’re also available in a nifty, portable little tin and are excellent value.
Available from:
VitamoreD D3
Available from Vitamore (£12.99)
Price per day (recommended dose): 43p
Star rating: 4/5
Made from calcifediol, the form of vitamin D that we make in the liver, the manufacturers claim that this form of vitamin D is more potent and better absorbed than cholecalciferol (used in the other supplements here). So no oil or vitamin K is deemed necessary. Contains 50mcg (1000% NRV) of vegan-suitable vitamin D3. The tiny capsules are very portable and easy to take.
Available from:
Performance Lab D3+K2
Available from Performance Lab (from £19)
Price per day (recommended dose): 48p
Star rating: 3.5/5
Although a hefty initial outlay (£57), this does get you a four-month supply of the recommended daily dose of 25mcg (500% NRV). They contain vitamin K to help draw calcium into the bones, which means they aren’t suitable if you’re on blood thinners or have certain health conditions.
Containing vitamin D3 from freeze-dried algae, they’re suitable for vegans. You’ll need to take them with fat-containing foods as they don’t contain any oil. Free from gluten, additives, preservatives and artificial colours.

Price per day (recommended dose): 13p
Star rating: 3.5/5
These gelatine-free gummies contain 25mcg (500% NRV) of vitamin D3. Inevitably higher in additives than some other formats, these gummies contain coconut oil to help with vitamin D absorption, although gummies generally aren’t as efficient a delivery mechanism as capsules. Suitable for age 12+ but beware the high sugar content.

Extracted from lanolin, this is not vegan. Our tester appreciated the clear instructions and the pleasant peppermint oil flavour.

How much vitamin D should I take?
The NHS advises a daily dose of 10 micrograms (or 400 International Units or IU) for most adults and children over the age of one, but individual requirements will vary depending on your age, skin colour, if you’re pregnant or breastfeeding, and how much time you spend outdoors (with your skin uncovered).
Our expert nutritionist suggests that 10-25mcg per day should be sufficient for most people. The NHS advises adults should not take more than 100mcg (4000 IU) a day.
For labelling purposes, the nutrient reference value (NRV) or recommended daily amount, that you will see on labels, is 5mcg. This is the amount set by the EU for food labelling purposes, this figure has been retained and now forms part of our UK food law.
How should I take a vitamin D supplement?
Vitamin D is fat-soluble, so a supplement is best taken with food to improve absorption. Most people in the UK should consider a supplement daily between October and late March, although individual needs vary.
What form of vitamin D should I take?
Vitamin D2 and D3 can both help a deficiency, although D3 is naturally produced in the skin and is generally considered slightly more active and longer-lasting. Vegans should be aware that D3 is often sourced from sheep’s lanolin, so look for a product made from lichen or micro-algae to avoid animal derivatives.
What format of vitamin D is best?
Look for an oil-based formula as D3 is fat soluble. This could be in capsule (or ‘pearl’) form, in a spray (as it bypasses the gut, the delivery is more direct) or in drops which can be added to food or drink.
Tablets tend not to be as easy to digest; gummies or chewables – although easier for children to take – may be more susceptible to heat and moisture which can affect stability and shelf life.
Vitamin K can be a useful addition to the supplement as it helps the body use calcium appropriately (although it is not suitable for all people including those on blood thinners).
