Vitamin K2, also known as menaquinone, is a form of vitamin K that is involved in various essential functions in the body. It is primarily produced by bacteria in the gut and can also be obtained from certain animal-based foods and fermented foods.

Good dietary sources of vitamin K2 include animal-based foods like meat, eggs, and certain types of cheese. Fermented foods, such as natto (a traditional Japanese dish made from fermented soybeans), also provide a significant amount of vitamin K2.

Vitamin K2 supports many key functions in the body including calcium metabolism, cardiovascular health, bone health and dental health.

Vitamin K supplements are generally not recommended for individuals taking blood-thinning medications like warfarin, as they can interfere with the medication's effectiveness. If you are on such medications or have any concerns, consult with a healthcare professional before taking prenatal supplements.

Vitamin K1 (phylloquinone) and vitamin K2 (menaquinone) are two forms of vitamin K with distinct functions and sources. Both vitamins are involved in blood clotting and bone health, but Vitamin K2 additionally plays a role in directing calcium to the bones and teeth while preventing its accumulation in soft tissues like arteries. Both forms of Vitamin K are essential for health.

Ellement is one of few brands that includes both Vitamin K1 and K2.

Less than 15% of prenatal supplement brands include both forms, and over one-third (38%) of prenatal supplement brands include no Vitamin K at all.

The two most common and well-studied forms of vitamin K2 are MK-4 (menaquinone-4) and MK-7 (menaquinone-7).

Ellement uses MK-7 (Menaquinone-7), which has a longer half-life in the body compared to MK-4, allowing for a more sustained supply and greater impact on bone health.
