• A randomized clinical trial found that vitamin K2 supplementation significantly reduces the frequency of nocturnal leg cramps (NLCs) in older adults.
• Participants taking vitamin K2 experienced a notable decrease in the severity and duration of NLCs compared to those receiving a placebo.
• The study reported no adverse events associated with vitamin K2, suggesting it may be a safe option for managing NLCs in the elderly.
• Researchers recommend further studies to confirm K2's efficacy and assess its impact on sleep quality and overall quality of life.
