Why customers take it

Healthy bones

Vitamin D is essential for the absorption of calcium and phosphorus, vital minerals for bone health. Adequate vitamin D helps maintain strong and healthy bones, and it's popular with people wanting to prevent osteoporosis and fractures.

Immune defence

Some people take vitamin D supplements to support overall immune function. Vitamin D is involved in the regulation of the immune system, and helps the body defend against infections as well as supporting balanced immune responses.

Mood & mental wellbeing

There is emerging research suggesting a link between vitamin D levels and mood disorders. Some people take vitamin D supplements to support mental well-being, especially during seasons with reduced sunlight exposure.

About Vitamin D
This Vitamin D supplement is delivered as Vitamin D3, which is the most absorbable and effective form of this nutrient.

Vitamin D is naturally manufactured when sunlight hits our skin. This explains why it is known as the sunshine vitamin. This essential nutrient has several important jobs which include regulating levels of calcium in the body, supporting the immune system and muscle function as well as contributing towards healthy bones and teeth.

Between October and March the levels of sunlight in the UK aren’t sufficient for us to make enough vitamin D. Public Health England recommends that during these months people should take a supplement to top up their levels.

Take one softgel daily with food or as directed by your healthcare professional. Do not exceed the stated dose.
