The Effects of Vitamin K2 on Recovery from Muscle-Damaging Resistance Exercise in Young and Older Adults: The TAKEOVER Randomized Controlled Trial - PubMed

5 hours ago

Vitamin K2 supplementation was studied for its effects on recovery from muscle-damaging resistance exercise in young and older adults.
The study was a double-blind randomized controlled trial with participants assigned to either vitamin K2 (240 μg/d) or placebo for 12 weeks.
No significant effects of vitamin K2 were found on muscle strength, physical function, muscle soreness, or inflammatory responses post-exercise in the overall group.
In older adults, vitamin K2 showed potential benefits on electromechanical delay (EMD) and electromyography root mean square (RMS) post-exercise.
Creatine kinase (CK) levels were lower at 72 hours post-exercise in older adults taking vitamin K2, but no clear pattern was observed for interleukin-6 (IL-6).
The study concluded that while some age-specific effects were noted, further investigation is needed to understand the implications of vitamin K2 on muscle recovery.
