Vitamin D Supplements

Support your bone health, immune system, and overall wellbeing with our range of Vitamin D supplements. It can be difficult to get enough vitamin D from sunlight alone, as modern lifestyles involve more time spent living and working indoors. Even when outdoors, factors like sunscreen, makeup, and clothing can block UV rays, limiting the body’s ability to naturally produce Vitamin D. Our Vitamin D oral sprays provide a fast-absorbing, convenient way to maintain healthy levels year-round.

Which Vitamin D Supplement do I Need?

There are varying dosage options available, designed to either boost or maintain Vitamin D levels suitable for year round use.

Why Vitamin D is Important

Vitamin D supports healthy bones, normal muscle function, and immune health. While a balanced diet can provide limited Vitamin D, your body relies on skin exposure to sunlight to produce this essential nutrient. Many people struggle to maintain adequate levels. Although a healthy balanced diet comes first, supplementation is a simple and reliable solution to top up and maintain necessary levels of Vitamin D.

How Much Vitamin D Do You Need?

The NHS recommends 10 micrograms (400 IU) per day for adults and children over 1, particularly during autumn and winter.

Individual needs may vary depending on lifestyle, sun exposure, and existing levels. Many people choose to supplement daily to maintain consistent intake year-round.


Benefits of Vitamin D

Vitamin D plays an essential role in maintaining overall health and wellbeing.


  • Bone health - Supports calcium absorption to help maintain strong bones and teeth.
  • Immune system support - Contributes to the normal function of the immune system.
  • Muscle function - Helps support normal muscle strength and performance.
  • Calcium absorption - Vitamin D contributes to normal absorption/utilisation of calcium and phosphorus.

Due to modern lifestyles and other factors limiting sunlight, particularly during autumn and winter, many people may not achieve optimal Vitamin D levels through sun exposure alone.

Who Needs Vitamin D?

Public Health England (PHE) recommends everyone take vitamin D supplements during autumn and winter. There are at-risk groups to be aware of:


  • Those pregnant or breastfeeding - Including vitamin D supplements in your pregnancy supplements can help infant growth and development.
  • Children under 5 - Any child could be at risk of developing rickets if they do not get enough vitamin D from sunlight, diet, or children’s vitamins.
  • Vegans - People who avoid meat and other animal products in their diet may be more at risk. Our vegan supplements are made with only plant-based ingredients to support these diets.
  • People with lower sun exposure - In the UK, UVB rays aren’t strong enough between November and March for vitamin D production.
  • People 65 and over - The body finds it harder to make vitamin D as you age., increasing the risk of falls and fragility fractures, so taking a daily vitamin D supplement is recommended.
  • People with darker skin pigmentation - Melanin acts as a natural sunblock, meaning those with darker skin pigmentation often require more sun exposure of supplementation to maintain sufficient levels.

Our oral sprays can be used under or on the tongue, but the most effective area is the inside of the cheek due to its rich vein system. This is also where we carry out our absorption testing.
