★★★★★ "I won't go back to high street supplements. The difference in quality is something you can actually feel." Susie

This is vitamin D3, cholecalciferol, dissolved in avocado oil. Vitamin D is fat soluble, so the oil is the carrier it absorbs best from.

Vitamin D supports the immune system, muscle function and the absorption of calcium, and it contributes to normal bones and teeth. Sunlight is the main source, and in the UK it is too weak for much of the year.

The dose is set by the number of drops, so one bottle covers children and adults at their own amounts. It contains two ingredients, avocado oil and cholecalciferol.

† Nutrient Reference Value (NRV*) not established

Avocado Oil, Cholecalciferol.

Also listed as cholecalciferol drops, liquid vitamin D3, vitamin D3 in oil, vitamin D drops.

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?

A liquid vitamin D3 in an avocado oil base, 500 IU per 4-drop serving, with age-based dosing for the whole family. It contains no K2, suiting those getting K2 elsewhere or who need D3 alone.

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 D contributes to the normal absorption of calcium and the maintenance of normal bones, and vitamin K contributes to the maintenance of normal bones and normal blood clotting. The pairing covers both of those authorised roles in one capsule.

Why vitamin D3 in oil drops rather than D2 or tablets?

D3, cholecalciferol, is the form the skin makes in sunlight and raises blood levels more reliably than D2, ergocalciferol, the plant-derived form in many prescriptions and fortified foods. Vitamin D is fat soluble, so it absorbs best carried in oil and taken with a meal; a dry tablet relies on the fat in whatever you ate. Drops also let the dose be set to the person, four drops for a standard daily amount and more only on a tested level or practitioner advice. The one thing drops do not offer is K2; for that see the D3 and K2 oil.

Why drops rather than tablets?

Drops let the amount be adjusted one drop at a time, and they suit anyone who cannot swallow tablets. Tablets need binders and a coating to hold their shape; this liquid contains only the active ingredient and its carrier.
