Description
Vitamin K is an essential nutrient that plays a critical role in the activation of proteins required for blood clotting and bone health. There are three major forms of vitamin K:
- Vitamin K1 (phylloquinone): Derived from plants.
- Vitamin K2 (menaquinone): Derived from bacteria in the gut or certain fermented foods like natto.
- Vitamin K3 (menadione): A synthetic derivative.
Health Benefits
- Bone health: Vitamin K is required for producing osteocalcin, a key bone protein. K2 (MK-7) is the most potent form for improving bone density and preventing fractures.
- Cardiovascular health: K2 helps prevent the hardening of arteries by directing calcium to bones rather than blood vessels.
Available Forms
- MK-7: Available in capsules or tablets, this is the most important dietary supplement form of vitamin K.
Dosage
- General health: 80–120 mcg daily.
- Osteoporosis: 180–360 mcg daily.
