Vitamin K2

What is Vitamin K2?

Vitamin K2, also known as menaquinone, is another fat-soluble vitamin but with a different biological role compared to Vitamin K1. It is mainly found in animal-based foods such as egg yolks, liver, and fermented products like natto. Vitamin K2 is essential for activating proteins involved in directing calcium to the bones and teeth, while keeping it away from the arteries, reducing the risk of arterial calcification.

Why do I have an intolerance?

Intolerance to Vitamin K2 can result from digestive issues similar to those affecting Vitamin K1 absorption, such as poor fat metabolism or malabsorption conditions like irritable bowel syndrome (IBS) or lactose intolerance (as some K2 sources are dairy-based). Additionally, the fermentation process in foods like natto might cause gastrointestinal discomfort or allergic reactions in certain individuals.

What can I do about it?

If you have difficulty tolerating Vitamin K2-rich foods, start by avoiding fermented products or dairy sources that trigger symptoms. You might benefit from consuming smaller amounts of K2 in different forms, such as non-fermented foods like chicken or eggs, which are generally easier to digest. Additionally, pairing K2-rich foods with healthy fats, like avocados or olive oil, can improve absorption without aggravating intolerance symptoms.
