Vitamin K2
Moderate Consensus

Expert Positions
The Verdict
3 of 5 experts recommend vitamin K2 — Hyman always pairs it with D3, Patrick provides the deepest mechanism via Triage Theory, and Johnson takes D3K2 daily. Attia conspicuously omits K2 from his bone health 'big three' (calcium, D3, magnesium) despite extensive bone health content. Huberman has zero coverage.
Where They Disagree
Attia defines bone health micronutrients as calcium + D3 + magnesium only, conspicuously omitting K2 across 5+ dedicated bone health episodes — while Hyman, Patrick, and Johnson all include K2 in their calcium metabolism framework.
Hyman treats D3+K2 as inseparable foundational supplements, while Attia and Huberman supplement with D3 without mentioning K2 — suggesting they either view K2's evidence as insufficient or consider it unnecessary when other bone health factors are addressed.
