Shop vitamin D, the sunshine vitamin, here at Holland & Barrett.

Vitamin D is a vital nutrient that plays a crucial role in numerous bodily functions, from building strong bones to supporting a healthy immune system. While our bodies can produce vitamin D from sunlight, shorter days and increased cloud cover can make it difficult to get enough, especially during winter.

Here at Holland & Barrett, we know just how important it is to keep your vitamin D levels topped up. That's why we offer a range of convenient options, including vitamin D oil capsules, tablets, chewy gummies, mini drops and sprays, to suit your preferences. You’ll also find different types, from high-strength vitamin D to vitamin D3 for bone health.

We all need vitamin D, but some may need it more than others:

People with dark skin as their skin produces less vitamin D from sunlight.
People who spend little time outdoors including those who work indoors, cover most of their skin when outdoors, or live in areas with limited sunlight.
Older adults as the skin's ability to produce vitamin D decreases with age.
Pregnant and breastfeeding women need extra vitamin D to support their own and their baby's health.
Children aged 1 to 4 can be at increased risk of deficiency.
People with certain medical conditions such as Crohn's disease, or coeliac disease.

Plus, vitamin D pairs well with other vitamins and minerals too. So, why not try complementing your vitamin D supplement with:

FAQs

What is vitamin D?

Vitamin D is a fat-soluble vitamin essential for several bodily functions. It's often called the "sunshine vitamin" because our skin produces it naturally when exposed to sunlight.

What does vitamin D do?

Vitamin D is a vital nutrient that works hard to keep your body healthy. It helps your body absorb calcium and phosphorus from your diet for healthy, strong bones and teeth. Plus, it plays an important role in supporting your immune system.

Am I at risk of vitamin D deficiency?

Yes, if you don’t spend enough time outside with uncovered skin during the summer months you may develop a vitamin D deficiency. From October to early March, the sunshine in the UK doesn’t contain enough UVB radiation for our skin to create vitamin D. This could leave you with low vitamin D levels.

How much vitamin D per day?

Most people can make enough vitamin D from sunlight between late March and September. However, everyone should consider taking a daily vitamin D supplement from October to early March. The NHS recommends that babies under 1 year need 8.5 to 10 mcg of vitamin D daily, whilst adults and children aged 1 year and over need 10 micrograms (mcg) of vitamin D daily. This includes pregnant and breastfeeding women and people at risk of vitamin D deficiency. However, individual needs can vary, so make sure to check with a doctor before taking a vitamin D supplement.

What contains vitamin D?

In addition to sunlight, vitamin D can be found in certain foods like oily fish, eggs, and fortified dairy products.

How can I increase my Vitamin D levels?

There are a few ways that you can increase Vitamin D levels such as making sure you spend time outside (especially in the summer months), eating foods that are rich in vitamin D or taking supplements.

What are the side effects of taking vitamin D?

If you stick to the recommended daily allowance of vitamin D, most people don’t experience side effects. If you take more vitamin D than is recommended you may experience side effects such as weakness, fatigue, headache, decreased appetite, nausea and vomiting.

Is vitamin D3 the same as vitamin D?

Vitamin D is a general term for a group of fat-soluble vitamins. Vitamin D3 is a specific type of vitamin D. Vitamin D3 is the type of vitamin D that our bodies produce when exposed to sunlight. Another form of vitamin D is vitamin D2, primarily found in plants, specifically yeast.

Does sunscreen block vitamin D?

Sunscreen blocks some of the UVB rays your body needs to produce vitamin D. But even with sunscreen, your skin can still produce some vitamin D. SPF is so important to help protect your skin, so make sure you continue to wear it when out in the sun!
