Vitamin K deficiency occurs when the body does not have enough vitamin K to support normal blood clotting and bone health. Low levels of this essential nutrient can increase the risk of excessive bleeding, easy bruising, and slower wound healing. In some cases, vitamin K deficiency may also affect bone strength over time. Causes can include poor dietary intake, certain digestive disorders, long-term antibiotic use, or conditions that reduce fat absorption. A balanced diet rich in leafy green vegetables, along with appropriate supplementation when recommended by a healthcare professional, can help maintain healthy vitamin K levels and support overall well-being.
