The score explained
evidence, testing and value, weighed before price
Why 7.6 of 10: Provisional: strong D3 core, emerging K2 add-on.
what’s good
- D3 plus K2
- Tested
worth knowing
- Pricier than plain D3
what the evidence says
The D3 half carries strong deficiency-conditional evidence; the K2 half is promising for directing calcium to bone but its added benefit on top of D3 remains emerging rather than established. Premium brand execution of a sensible pairing.
