VITAMIN K2

What is vitamin K2? 

Vitamin K2, also known as menaquinone, is a fat-soluble vitamin that belongs to the vitamin K family. It plays a crucial role in regulating calcium metabolism and promoting proper bone and cardiovascular health.

Vitamin K2 is synthesised by certain bacteria in the gut and is also found in some animal-based and fermented foods. It works by activating proteins that help transport calcium to the bones and teeth while preventing its accumulation in arteries and soft tissues.

Research suggests that vitamin K2 may have benefits beyond its role in bone and cardiovascular health, including potential anti-inflammatory and anticancer properties.

A 2015 study highlighted the influence of vitamin K2 on various diseases. It suggested that individuals with a deficiency of this vitamin, combined with certain lifestyle factors, may be at increased risk of developing chronic conditions such as diabetes, osteoporosis, cancer, inflammatory diseases, and cardiovascular diseases.

The study also indicated that supplementation with vitamin K2 could potentially provide significant benefits in managing and preventing these conditions. Vitamin K2 plays a role in regulating calcium metabolism and promoting proper bone and cardiovascular health, which are important factors in disease prevention and management.

Vitamins or minerals that can enhance the absorption of vitamin K2 include:

  • Dietary Fat: Vitamin K2 is a fat-soluble vitamin, and like other fat-soluble vitamins, it is absorbed more effectively when consumed with dietary fats. Including healthy fats in your meals can improve vitamin K2 absorption.
  • Vitamin D: Vitamin D plays a role in calcium metabolism and bone health, and it can interact with vitamin K2 in various metabolic processes related to bone mineralisation. Ensuring sufficient vitamin D levels can indirectly support vitamin K2's bone-related functions.
  • Calcium: Calcium is essential for bone health, and vitamin K2 plays a role in directing calcium to the bones and teeth. Ensuring sufficient calcium intake can indirectly support vitamin K2's bone-related functions.
  • Magnesium: Adequate magnesium levels are important for overall bone health and may play a role in the utilisation of both vitamin K2 and calcium in bone metabolism.
  • Vitamin A: Vitamin A is involved in various metabolic processes, including bone health. Adequate vitamin A levels can contribute to overall bone health, and it may interact with vitamin K2 in some metabolic processes.
