Vitamin K2 (Menaquinone)

Overview:

Vitamin K2 is a form of vitamin K known for its role in bone and cardiovascular health. Unlike K1, K2 is involved in the regulation of calcium deposition, ensuring calcium reaches the bones and teeth while preventing its accumulation in arteries.

Sources:

Vitamin K2 is found in fermented foods like natto, cheese, and yogurt, as well as in animal products such as meat and egg yolks. It is also available in supplement form.

Functions:

Bone Health: Vitamin K2 activates proteins that bind calcium to the bone matrix, promoting strong and healthy bones.

Cardiovascular Health: It prevents arterial calcification, reducing the risk of cardiovascular diseases by ensuring calcium does not deposit in the arteries.

Dental Health: By directing calcium to teeth, vitamin K2 helps maintain strong and healthy teeth.

Deficiency:

Vitamin K2 deficiency can result in poor bone health, increasing the risk of osteoporosis and fractures. It can also contribute to cardiovascular problems due to improper calcium regulation.

Toxicity:

Vitamin K2 is generally safe with low toxicity risk. However, excessive intake should be avoided, especially in individuals on anticoagulant therapy, as it can interfere with blood clotting medications.
