Vitamin K2 Didn't Help Muscle Recovery in This 12-Week Trial
This study suggests vitamin K2 at this dose does not meaningfully improve post-exercise muscle recovery.
After 12 weeks of daily vitamin K2 supplements, neither young nor older adults saw improvements in muscle strength, soreness, or physical function after a tough leg workout. Some secondary measures in older adults showed small shifts in muscle activation speed and a damage marker at 72 hours. But the main outcomes were all null. The researchers say the age-specific signals need more study before drawing conclusions.
