What Are The Benefits Of Vitamin K1?
Vitamin K1, also known as phylloquinone, is an essential fat-soluble vitamin that plays a critical role in blood clotting and bone health. While often overlooked, ensuring adequate vitamin K1 intake is crucial for overall well-being.
- Blood clotting: it's essential for the synthesis of proteins that enable blood clotting.
- Bone health: it contributes to bone mineralization and helps prevent osteoporosis.
- Cardiovascular health: some studies suggest a potential role in preventing arterial calcification.
NIH (National Institutes of Health) recommends the daily intake of vitamin K (which includes both vitamin K1 and vitamin K2), it varies across different life stages:
- Children 4-8 years: 55 mcg vitamin K
- Children 9-13 years: 60 mcg vitamin K
- Teens 14-18 years: 75 mcg vitamin K
- Adult men: 120 mcg vitamin K
- Adult women: 90 mcg vitamin K
- Pregnant and Breastfeeding women: 90 mcg vitamin K
Important note: if you're taking blood-thinning medications like warfarin, or some other medications like antacids, antibiotics, seizures, high cholesterol, cancer drugs may be affected by vitamin K1, it's crucial to maintain a consistent vitamin K1 intake and consult with your doctor about your diet.
