The website “Abonite.D” reported that vitamin K2 may help reduce the frequency, severity, and duration of nocturnal leg cramps (cramps) in the elderly, according to a recent scientific study.
The website, which is the official portal for German pharmacists, explained that 199 people aged 65 years or older were randomly distributed to receive either 180 micrograms of vitamin K2 or a placebo daily.
Initially, the average number of leg cramps for participants in both groups ranged from two to three per week.
After the first week, there was a clear indication that vitamin K2 reduces cramps, and after 8 weeks, the number of nighttime leg cramps decreased in the group that took vitamin K2, while it increased in the group that took the placebo.
The intensity of cramps decreased significantly and their duration decreased in the group that took vitamin K2 compared to the placebo group.
Based on these results, the researchers concluded that vitamin K2 supplements significantly reduce the frequency, severity, and duration of nocturnal leg cramps in older adults.
Where do we find vitamin K?
Vitamin K is an essential biochemical compound required for optimal body function. Vitamin K can exist in different forms, which can be distinguished by two main compounds, phylloquinone (K1) and menaquinone (K2).
Vitamin K1 is mainly found in vegetables and plant chlorophyll. The main sources of vitamin K1 include spinach, cabbage, and kale. Other than leafy vegetables, vitamin K1 can also be found in fruits such as avocado, kiwi, and grapes. While vitamin K2 menaquinones are manufactured by bacteria, they are primarily found in food in which bacteria are part of the production process. The main known sources of vitamin K2 are meat and dairy products.
