What’s in the drop

A close-up abstract photograph of extra virgin olive oil

Spanish Extra Virgin Olive Oil

Organic and chosen as the carrier oil. Since Vitamin D3 is fat-soluble, it requires an oil for absorption, a gentle base for a developing system.

Vitamin D3

The full daily dose the NHS recommends for babies from birth. Vitamin D is needed for normal bone growth in children and contributes to normal immune function.

Certified Organic

Certified organic and vegan-friendly, with no added sugar, sweeteners, artificial colours, flavours, preservatives or gums. Just clean nutrition you can trust from day one.

The Baby D3 Feeling

Strengthen Defences

Vitamin D contributes to the normal function of the immune system in children, helping to build strong natural defences from the very beginning.

Strong Bones & Teeth

Vitamin D is needed for the normal growth and development of bone in children, and contributes to the maintenance of normal teeth.

Muscle Function

Vitamin D contributes to normal muscle function, supporting the strength behind every reach, roll and wobbly first step.

NHS-Recommended Dose

One 0.5ml drop delivers the full 10µg the NHS recommends daily for babies from birth. No guesswork, no under-dosing.
