When we hear about essential vitamins, Vitamins C, D, and B12 dominate the conversation. We all know that Vitamin K plays an important role in the blood clotting cascade. Newborns are routinely given Vitamin K injections shortly after birth because they naturally have very low levels, putting them at risk of serious bleeding disorders, but that is not the only thing it does.
Vitamin K2 helps maintain bone density and prevent osteoporosis. Taking Vitamin D without adequate Vitamin K can lead to arterial plaque buildup rather than stronger bones as Vitamin K helps prevent calcification of artery walls, keeping them flexible.
The good news is that Vitamin K deficiency is rare in healthy adults, but individuals with cholestasis, coeliac disease, cystic fibrosis, and small bowel disease can develop it. Some antibiotics also interfere with Vitamin K metabolism. If you bruise easily or bleeding takes a long time to stop, it could be due to low Vitamin K levels. It’s also important to know that people taking blood thinners need to monitor their Vitamin K intake carefully, as it can make these medicines less efficacious.
Another important thing to understand is the difference between Vitamin K1 and K2. K1 is crucial for hemostasis and is found in leafy greens. K2 plays a key role in calcium transport and is found in fermented foods and animal products.
Do you think Vitamin K deserves more public awareness compared to other commonly discussed vitamins?
