Buying Guide

Choose the right K2 form

MK‑4 and MK‑7 differ in dose and half-life; MK‑7 offers longer circulation while MK‑4 is often used in higher milligram doses for short-term effects

Look for vitamin D3 combinations

Vitamin D3 works synergistically with K2 to support calcium metabolism and bone mineralization, so combined D3+K formulas can be more efficient

Check potency per serving

Compare microgram or milligram amounts of MK‑4 and MK‑7 per serving to match clinical guidance or your practitioner's recommendation

Consider delivery form and diet fit

Softgels and capsules differ in fill and excipients; choose vegan or non‑vegan formulations based on dietary restrictions

Assess price relative to serving count

Evaluate cost per serving and total softgel/capsule count to determine value rather than comparing sticker prices
