Vitamin K first gained popularity in the medical community due to its role in
blood clotting. Further research, however, has established that this vitamin has several other cardiovascular benefits as well.
For example, vitamin K appears to improve cardiovascular health by
preventing calcium buildup in the arteries. Vitamin K2 helps support the maintenance of healthy bones and keeps the presence of calcium away from the arteries and the heart, to ensure it is deposited into the bones.
15 studies have indicated that vitamin K may improve your bone density. One study found that
vitamin K helps maintain your levels of osteoprotegerin, which is integral to your bone health.
Another study found that
vitamin K supplementation improved both the bone density and bone shape of post-menopausal women. Patients are commonly given vitamin K supplements after lung or heart surgery, and research found that
this practice improves bone density. In addition, research indicates that
people who take vitamin K are less likely to get bone fractures.
Insulin sensitivity is one of the symptoms of diabetes, and one study found that supplementing with
vitamin K may improve insulin sensitivity. Therefore, this nutrient may be particularly important in insulin-affected conditions such as diabetes.
Vitamin K supplementation may help
improve the symptoms of Alzheimer’s disease. This vitamin also appears to have neuroprotective properties, so it may prevent damage to nerve cells caused by oxidative stress. Plus, vitamin K has appeared to
prevent neuroinflammation, so it may support the reduction of inflammation in your brain and nervous system.
