Vitamin K

Vitamin K foods is a fat-soluble vitamin, which means your body stores it in fat tissue and the liver. It is available in both natural forms and as a synthetic supplement, the natural forms are vitamin k1   (Phylloquinone) plant based sources and Vitamin K2 (Menaquinone) animal sources. The synthetic forms of Vitamin K are Vitamin K3 (Menadione) ; it is  mainly used in animal feed; not recommended for human use due to potential toxicity, and MK-8 and MK-9 Less common subtypes of Vitamin K2, found in certain fermented foods. Ensuring a diet rich in both Vitamin K1 and K2 can help maintain optimal health, supporting both blood clotting and bone strength.

Types of Vitamin K foods and Its Sources 

Vitamin K is grouped into two classes ; Vitamin K1 and Vitamin K2 each are different from one another based on their source and based on uses. Vitamin K can be obtained from a variety of food sources. There are two sources , Plant based and animal based source. As we say there are two types of vitamin k, Vitamin K1 which are plant based foods and Vitamin K2 are Animal based food sources.

• Promotes Cell Health

Vitamin K helps regulate cell growth. By controlling how cells grow and divide, it prevents the formation of abnormal cells that could lead to cancer.

• Fights Inflammation

Chronic inflammation is linked to many types of cancer. Vitamin K has anti-inflammatory properties, helping to reduce inflammation in your body and lowering cancer risk.

• Supports Natural Cell Death

Our bodies naturally get rid of damaged or unnecessary cells through a process called apoptosis. Vitamin K supports this process, ensuring that potentially cancerous cells are removed before they can grow and spread.

Emerging research suggests anti-cancer properties, helping to inhibit the growth of cancer cells and reduce the risk of certain cancers.

7. Supports Skin Health

We are saying that it supports skin health yes it support but how we are looking it

Promotes Wound Healing

• Blood Clot Formation: Vitamin K activates clotting factors in the blood, which leads to the formation of a clot to stop bleeding.
• Tissue Repair: After clotting, Vitamin K supports collagen production and other proteins essential for tissue repair and regeneration.

Reduces Bruising

• Clotting Efficiency: Enhances the efficiency of blood clotting, preventing excessive bleeding into tissues and reducing bruising.
• Bruise Resolution: Accelerates the breakdown and absorption of blood that has leaked into tissues, speeding up bruise healing.

Enhances Skin Repair

• Collagen Production: Supports the synthesis of collagen, maintaining skin elasticity and aiding in faster recovery from injuries.
• Cell Regeneration: Promotes the regeneration of skin cells, ensuring healthier and more resilient skin.

Alleviates Skin Conditions
