In a study conducted by Dr. Jing Tan and colleagues from the Third People’s Hospital of Chengdu, older adults over the age of 65 took part in a clinical trial to see if vitamin K could reduce nighttime leg cramps.
Over the course of eight weeks, 199 participants received either a daily vitamin K supplement (180 mcg) or a placebo, with the goal of measuring any changes in the frequency, severity, and duration of their leg cramps.
Here’s what the researchers found:
Frequency: Those in the vitamin K group experienced a drop in the average number of leg cramps per week, going from around 2.6 cramps to less than one per week. In contrast, the placebo group saw no improvement.
Severity: Participants taking vitamin K also reported that their cramps were less intense. They noted a significant decrease in cramp severity compared to those taking the placebo.
Duration: Not only were cramps less frequent and less intense, but they also didn’t last as long. For those in the vitamin K group, the duration of each cramp was almost halved, making for a faster return to restful sleep.
The best part? No adverse side effects were found in the vitamin K group, pointing to a safe and gentle option for cramp relief.
So, how might vitamin K help ease leg cramps? While this nutrient is most famous for supporting bone health and blood clotting, it’s also involved in muscle function and circulation.
Researchers think that vitamin K may promote better blood flow and reduce muscle tightness, which could explain its role in reducing nighttime cramps.
For anyone regularly dealing with leg cramps at night, vitamin K supplementation may be worth a conversation with your healthcare provider. It’s a simple, natural approach that could fit easily into your existing health routine.
And if you’re an older adult or know someone who is, this may be especially relevant—as muscle cramps often become more frequent and painful with age.
Vitamin K supplements are generally safe, but it’s best to consult your doctor, particularly if you’re taking blood thinners or have any other health conditions.
If you’re looking for food sources of vitamin K, here are some top options to consider:Leafy Greens: Spinach, kale, and collard greens pack a vitamin K punch.Broccoli: This versatile veggie offers a solid dose of vitamin K along with other essential nutrients.Fermented Foods: Natto, a fermented soybean dish popular in Japan, is especially high in vitamin K.For those dealing with nighttime leg cramps, it’s easy to feel frustrated by the lack of solutions that don’t come with potential side effects. But with vitamin K supplementation, you might be able to enjoy a more restful night without the surprise wake-up call of a leg cramp.
To restful nights and natural solutions,
