What it is

Menaquinone is a form of vitamin K, which is essential for blood clotting and bone health. It is found naturally in some fermented foods like natto (fermented soybeans) and certain cheeses. Menaquinone can also be produced through bacterial fermentation.

Why it's used

Menaquinone is primarily added to foods as a nutrient supplement, particularly in fortified products. It is often found in energy drinks, protein powders, and plant-based milk alternatives to boost their vitamin K content.

Health notes

Menaquinone is recognized as safe and effective for its intended use by the FDA. It is considered a nutrient and is not subject to the same regulatory scrutiny as food additives. The U.S. National Academies of Sciences, Engineering, and Medicine have established a tolerable upper intake level for vitamin K. International bodies like EFSA have also evaluated vitamin K, but no specific numeric limits are stated here. Evidence suggests vitamin K plays a role in bone metabolism and cardiovascular health.

Allergen info

Menaquinone itself is not derived from any of the 9 major allergens. However, it may be produced using fermentation processes that involve other ingredients, so checking specific product labels is advised. Not a gluten source.
