Support bone health and immunity with flexible dose liquid vitamin D3
A standalone vitamin D3 oil in an avocado oil base, providing 500 IU (12.5mcg) per 4 drop serving. This product is specifically formulated with age based dosing for the whole family, from children under 13 through to adults. Vitamin D3 (cholecalciferol) is essential for calcium absorption, bone mineralisation, immune regulation, mood and over 200 gene expressions throughout the body. Deficiency is endemic in the UK, where limited sunlight from October to March means most people cannot synthesise adequate vitamin D through skin exposure for at least half the year.
The avocado oil base provides a naturally fat soluble carrier alongside beneficial monounsaturated fatty acids. This product does not include vitamin K2, making it suitable for those who are already getting K2 from other sources or who need D3 without K2 (for example, those on warfarin who cannot take K2). The bottle provides 735 servings per 100ml.
Key benefits:
- Bone health immunity and mood
- Flexible drops for precise dosing
- Oil based for better absorption

Directions for use:
Under 13 years: 4 to 8 drops per day with food (500 to 1000 IU). 13 to 18 years: 12 to 16 drops per day with food (1500 to 2000 IU). Adults 18+: 20 drops per day with food (2500 IU).
Take with any meal. The drops can be placed directly onto food or into a drink. For adults, the 20 drop dose provides 2500 IU, which is within the safe daily range recommended by most clinical guidelines for maintenance. For children, start with the lower end of the range and adjust based on professional guidance.
If taking this product without K2, consider pairing with standalone Vitamin K2 (150mcg capsule) to ensure calcium is properly directed to bones rather than soft tissues, unless K2 is contraindicated.

Frequently asked questions
Why take Vitamin D3 Oil?
Vitamin D3 Oil supports bone health, immune function, and mood regulation.
How much vitamin D do I need?
Most adults benefit from 2000-4000 IU daily, depending on blood levels.
When should I take vitamin D?
Take with your largest meal containing fat for best absorption.
Can I take too much vitamin D?
Yes, vitamin D is fat-soluble. Get your levels tested and work with a practitioner to find your optimal dose.
Why is vitamin D paired with K2?
Vitamin K2 helps direct calcium to bones rather than arteries. They work synergistically for bone and cardiovascular health.
