Which vitamin helps in blood clotting during an injury? 

Correct option is D

The correct answer is: D. Vitamin K

Explanation: Vitamin K is a fat-soluble vitamin essential for blood clotting.It exists in two primary forms:

• Vitamin K1 (Phylloquinone): Predominantly found in green leafy vegetables like kale, spinach, and broccoli.

• Vitamin K2 (Menaquinone): Found in fermented foods and animal products.

The "K" in vitamin K comes from the Danish word koagulation, meaning coagulation, highlighting its role in blood clotting.

Information Booster:

• Deficiency Disease: A deficiency in vitamin K can lead to Vitamin K Deficiency Bleeding (VKDB), characterized by excessive bleeding due to impaired blood clotting.

• Role in Blood Clotting: Vitamin K is crucial for synthesizing clotting factors such as prothrombin (Factor II), Factor VII, Factor IX, and Factor X.

• Absorption: Vitamin K is absorbed in the small intestine and requires bile for proper absorption.

• Storage: The body stores vitamin K in the liver and fat tissues.

• Daily Requirements:

  • Adult Women: 90 micrograms

  • Adult Men: 120 micrograms

• Food Sources:

  • Vitamin K1: Green leafy vegetables (e.g., kale, spinach), broccoli, Brussels sprouts, cabbage.

  • Vitamin K2: Fermented foods (e.g., natto), animal products (e.g., meat, eggs), dairy products.

Additional Information:

• Vitamin A: The scientific name for Vitamin A is retinol. It is essential for vision, immune function, and skin health. A deficiency can lead to night blindness and a weakened immune system.

• Vitamin B12: The scientific name for Vitamin B12 is cobalamin. It is important for nerve function, red blood cell production, and DNA synthesis. Deficiency can lead to pernicious anemia.

•  Vitamin C: The scientific name for Vitamin C is ascorbic acid. It is essential for collagen synthesis, wound healing, and the immune system. Its deficiency leads to scurvy, which causes fatigue, bleeding gums, and bruising.
