Buying Guide

Choose the K2 form that matches your goals

MK‑4 has a shorter half‑life and is often used in higher daily doses, while MK‑7 persists longer in the bloodstream; select products (MK‑4, MK‑7, or combined) based on desired dosing frequency

Look for vitamin D3 pairing

Vitamin D3 supports calcium absorption and is commonly paired with vitamin K complexes to target bone health, so consider supplements that include D3 when bone support is your priority

Check potency and serving size

Compare microgram or milligram amounts per serving and the recommended daily serving to understand total daily intake and whether the product fits your dosing preferences

Consider capsule type and diet compatibility

If you need vegan or plant‑based options, look for formulations labeled vegan or using plant glycerin softgels; other products use animal‑derived ingredients or different capsule types

Evaluate value by concentration and bottle count

Assess cost relative to MK‑4/MK‑7 concentration and number of servings per container to determine which option offers better value for your required dose
