Vitamin K2

Everything You Need to Know About Vitamin K2: An Essential Nutrient for Healthy Bones and Arteries

Vitamin K is critical to our health, but its benefits go beyond its known role in blood clotting. This vitamin also supports the activity of a special tissue protein called matrix Gla protein, which is essential for maintaining supple and elastic artery walls, articular cartilage and other soft tissues in the body. In addition, vitamin K is necessary for the activity of osteocalcin, a bone protein that plays a crucial role in the formation and maintenance of healthy and well-mineralized bone tissue.

Types and Sources of Vitamin K

Vitamin K comes in two main forms: K1 (phylloquinone) and K2 (menaquinone). While vitamin K1 is mainly found in green leafy vegetables such as spinach, broccoli and cabbage, vitamin K2 is found in foods such as natto (fermented soybeans), meat, eggs and dairy products such as cheese and yogurt. Menaquinone-7 (MK-7) is a powerful, natural form of vitamin K2 produced by fermentation and considered the most effective form for optimizing vitamin K status in the body.

Important Functions of Vitamin K2

Vitamin K2 plays an essential role in several body processes, including:

• Supports bone health by contributing to the formation and maintenance of healthy bone tissue.
• Maintaining supple and elastic artery walls, which helps prevent arteriosclerosis (stiffening of the arteries).
• Possible prevention of osteoporosis, arteriosclerosis, arthritis/osteoarthritis, metabolic syndrome, cystic fibrosis and even certain forms of cancer.

Signs and Indications of a Possible Vitamin K2 Deficiency

A vitamin K2 deficiency can lead to symptoms such as prolonged bleeding time, spontaneous bleeding, bruising, osteoporosis and accelerated loss of blood vessel elasticity. Indications for an inadequate vitamin K status may include: osteoporosis, increased vitamin K requirements during growth spurts, arteriosclerosis, increased risk of arteriosclerosis, arthritis/osteoarthritis, metabolic syndrome, cystic fibrosis, certain forms of cancer, inflammatory bowel disease, Alzheimer's disease, and even in COVID-19 and post-COVID-19.

Safety and Usage Advice

For most adults, a daily dosage of 90-180 mcg of vitamin K2 is recommended for general maintenance. People taking anticoagulants should be careful with vitamin K2 supplements and only use these supplements under the guidance of a doctor, because vitamin K2 can reduce the effect of these medications.

Conclusion

Vitamin K2 is an essential nutrient with several health benefits, ranging from bone health to maintaining elastic artery walls. It is important to get enough vitamin K2 through diet and supplements, especially for people at risk of deficiency. Always consult a doctor before starting to take vitamin K2 supplements, especially if you are taking other medications.
