Vitamin K is a fat-soluble vitamin that stops blood clotting (wounds continuously bleeding), and produces healthy bone tissue. Studies suggest a correlation between high Vitamin K consumption and low risk of bone fracture. Vitamin K is in the liver, brain, heart, pancreas, and bone. For this reason, it rarely reaches toxic levels in your system even with high intakes.
Vitamin K has two components: K1, a.k.a. phylloquinone, which is in most leafy green vegetables such as spinach, broccoli and brussel sprouts. K1 goes straight to the liver. K2, a.k.a. menaquinone, is in fermented foods and animal products, such as yogurt, kimchi, chicken, egg yolks and butte. K2 circulates in your blood for longer and is used in tissues throughout the body.
Vitamin K also prevents heart disease, since it also activates a protein that prevents calcium from depositing in your arteries. All in all, Vitamin K ticks a lot of health boxes.
Vitamin K deficiency is rare in adults, but it may occur in people that are taking antibiotics. Antibiotics may destroy bacteria in your gut, which can consequently decrease the levels of vitamin K in your body. This is particularly relevant for people that have taken antibiotics for a few weeks and have poor appetite. Vitamin K is definitely not a vitamin to overlook, so keep it in mind when restocking your supplement kit.
