Vitamin K in foods: distinguishing between K1 and K2
Vegetables, fermented foods, and supplements: how to interpret sources of vitamin K without confusing K1, K2, and the amounts consumed.
Not all foods provide the same form
Leafy green vegetables are important sources of K1. Certain animal and fermented foods provide menaquinones, the K2 forms. Natto, a fermented soy-based food, is particularly rich in MK-7; in other fermented products, the content can vary significantly based on processing and microorganisms.
From the name of the food to your day
“I eat cheese” or “I eat vegetables” does not yet describe a daily diet. Note down which foods you consume, the typical portion size, and the frequency: an occasional presence versus a daily one provides different information. Avoid deriving a precise intake from a photograph of a plate or a generic list found online.
If you wish to discuss your nutrition with a professional, bring a few representative days, including one from the weekend. Also, record any fortified foods and supplements actually used: their contribution does not emerge from a simple shopping list.
Food and bottles answer different questions
A food enters a meal along with other nutrients. A supplement bottle, on the other hand, allows you to read a declared composition and intake. For K2 Biomed, the label indicates 10 drops per day and 25 µg of vitamin K. This information does not authorize you to replace vegetables or to establish equivalencies such as “one dose is equal to one plate.”
If you are taking anticoagulant therapy, consult the interactions guide first: abruptly changing your diet or adding K2 requires a specific discussion regarding the medication used.
