Vitamin K2 Didn't Help Muscle Recovery in This 12-Week Trial
Summary
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.
Practical Takeaway
This study suggests vitamin K2 at this dose does not meaningfully improve post-exercise muscle recovery.

Eight Hyped Compounds Failed to Extend Lifespan in a Major Mouse Study
The NIA's Interventions Testing Program tested eight compounds across three lab sites in genetically diverse mice. None extended lifespan. That includes astaxanthin, alpha-ketoglutarate, pioglitazone,...
This study suggests that dose and timing matter enormously, and early lifespan results in mice often don't hold up.
