Exercise and eating a healthy balanced diet are essential to helping your body get all the nutrients it needs to stay well. But there’s one vitamin, try as you might by eating well, that you will need to supplement in autumn and winter: vitamin D. You can blame it on the weather.

Dr Sam Oliver, a reader in sport and exercise science at Bangor University, says: “From October through to March due to insufficient sunlight, a low-dose daily oral vitamin D3 supplement might be needed to maintain vitamin D sufficiency.”

The sunshine vitamin, so-called because we get most of it from the sun’s rays, is essential for maintaining musculoskeletal health by supporting our bones, teeth and muscles. Research has also linked it to boosting the immune system, and Dr Oliver and his colleagues made another significant discovery last year.

“More recently, a greater understanding of vitamin D’s role within the immune system means that maintaining vitamin D sufficiency may also be important to prevent and cope with respiratory infections,” he says. “For example, our recent research indicates winter vitamin D supplementation reduces the duration and severity of the common cold.”

How we tested the best vitamin D supplements

Now you know the need for vitamin D, let us try to help you demystify the vast number of options out there, so you can decide which is best for you and your health.

We’ve scoured the market and selected the supplements we’d be happy to take ourselves, after listening to the expert’s advice. We’ve included a range of products with several methods of consumption, noting how easy they were to take, and a number of different strengths. Please note that doses of more than 1,000IU are rarely needed unless you have a condition or lifestyle that requires higher potency vitamin D (please speak to your clinician before starting a high-potency supplement).

  • Why we love it
    • Letterbox-friendly
    • No nasty aftertaste

They say good things come in small packages, and this supplement proves that. Inside this compact, letterbox-friendly foil bag – which uses less plastic than conventional pill bottles – are 180 tiny tablets measuring 6mm, each delivering a high-quality 1,000IU vitamin D hit. They are incredibly easy to swallow and leave no aftertaste, so they are perfect for anyone who struggles to take pills without gagging.

Myvitamins vitamin D3 softgels, 1,000IU

best vitamin d supplements Myvitamins vitamin D3 softgels, 1,000IU
  • Best: Budget vitamin D supplement
  • Size: 180 tablets
  • Why we love it
    • Vegan
    • Excellent value for money
    • Easy to take
    • No unpleasant aftertaste
  • Take note
    • Best taken with food

Gel capsule supplements tend to be among the easiest to swallow but they often contain gelatine, meaning they are not suitable for vegans. But not these Myvitamins vitamin D3 softgels. Each capsule of this high-strength supplement is easy to swallow and made using lichen algae, helping you to get your daily vitamin D needs while on a plant-based diet.

The one-a-day dosage means a 180-capsule bottle provides almost six months’ worth of vitamin D and the pocket-friendly price means that they’re excellent value for money. We also like that the pot is made from recycled materials and is fully recyclable again when it’s empty.

  • Best: For vegans
  • Size: 60 tablets
  • Dietary needs: Vegan
  • Why we love it
    • Vegan friendly

Many supplements contain milk, come in gelatine capsules or have been tested on animals, so we wanted to include something that is suitable for vegans. The Nature’s Own vitamin D3 is cruelty-free and takes the nutrient from lichen extract. Our tester found the one-a-day tablets easy to swallow and liked that they are free from GMO, gluten and yeast. There are 60 pills in each bottle, giving you a two-month supply.

best vitamin d supplements Myvitamins vitamin D gummies, 1,000IU
  • Best: Vitamin D gummies
  • Size: 60 gummies
  • Dietary needs : Vegetarian
  • Why we love it
    • Easy way to take supplements
    • Delicious orange flavour
  • Take note
    • Gummies contain sugar

This vitamin D supplement being bright orange is highly appropriate because each one-a-day gummy delivers 500 per cent of your recommended daily dose of the sunshine vitamin whatever the weather. Gummies are a delicious way to take supplements, and it could help make the habit of taking them regularly easier to form because you’re likely to look forward to their yummy taste – just like our tester did.

The Myvitamins vitamin D gummies are also suitable for vegetarians and the packaging is recyclable. However, like many gummy supplements, they do contain sugar, which is something to be aware of if you’re keeping an eye on your intake.

Vitamin D FAQs

Why is vitamin D important?

“Vitamin D deficiency can lead to bone problems, such as rickets in children and bone pain and muscle weakness in adults, which may increase the risks of falls and fractures in the elderly, as well as increased susceptibility to infection,” explains Dr Sam Oliver, a reader in sport and exercise science at Bangor University.

What foods are rich in vitamin D?

If you’re looking to increase your intake of vitamin D through food, Dr Oliver recommends oily fish, red meat, egg yolks, mushrooms and fortified foods, including breakfast cereals.

When do I need to supplement my diet?

Given the insufficient sunlight, Dr Oliver notes that it’s best to do so from October through to March. In the UK, from April through to September most people can obtain the vitamin D they need from the skin (endogenous) synthesis via short daily exposures to sunlight, i.e., about 15 minutes of midday sun exposure in shorts and a T-shirt.

How much should I take?

A daily oral 10 micrograms (400IU) vitamin D3 supplement during autumn and winter.

Are there any contraindications to be aware of?

Vitamin D toxicity is possible with high doses (more than 4,000IU per day) of oral supplementation.

Are there other vitamins that can be taken with vitamin D to support absorption?

We’ve heard in conversation sometimes that orange juice (vitamin C) might be helpful; however, the only randomised controlled trial we’re aware of showed no difference between vitamin D bioavailability when consumed with orange juice compared to capsules.

The verdict: Vitamin D supplements

Convenience, quality and value for money make the Nutrition Geeks vitamin D3 1,000IU our best buy. They are extremely easy to take, generate less plastic waste than conventional pill bottles and carry a price tag that is accessible for most people.

We’d also recommend Aguulp for immunity if you’re looking to combine multiple vitamins and minerals in one easy-to-take supplement, and the Dr Vegan vitamin D3 for its eco-friendly credentials.
