The formula

Vitamin D3 × Vitamin K2

Vitamin D3

Vitamins D and K are fat-soluble, so we dissolve them in cold-pressed extra virgin olive oil rather than a dry tablet. Take it with a meal and you have everything needed for absorption.

Vitamin K2

K2 is supplied as MK-7, the long-chain form, at least 99% all-trans. It’s made by fermenting chickpeas, so the softgel contains no soy and no natto.

What to expect

A realistic timeline, not a promise.

  1. Day 7 Habit formed One softgel with your main meal. Pair it with something you already do daily, like breakfast or dinner.
  2. Day 30 One month in Half a bottle used. Most useful from October to March, when UK sunlight is too weak for skin to make vitamin D.
  3. Day 90 Ongoing foundation Halfway through your second bottle. Vitamin D works on daily intake, so the routine matters more than any single dose.
