Vitamin K2 is a lesser-known vitamin that plays a crucial role in numerous body activities, including blood clotting, bone health, and cardiovascular health. It belongs to a family of fat-soluble vitamins includes vitamins A, D, and E and is naturally generated by various microorganisms and animals, including humans. Vitamin K2 is needed for activating specific proteins in the body that are involved in bone metabolism and blood vessel health. In recent years, research has also revealed a relationship between vitamin K2 and blood pressure, making it a vital mineral for cardiovascular health.

Blood Pressure and Its Effect on Health

Blood pressure refers to the force of blood on the walls of the arteries as it is pushed by the heart. It is measured in millimeters of mercury (mmHg) and consists of two numbers: the systolic pressure (top number) and the diastolic pressure (bottom number) (bottom number). High blood pressure, often known as hypertension, can raise the risk of heart disease, stroke, and renal failure. It is commonly nicknamed the “silent killer” since it often exhibits no symptoms. Keeping a stable blood pressure through lifestyle modifications and potential medication is vital for overall health and lifespan.

Vitamin K2 and Cardiovascular Health

Vitamin K2 may have a significant role in cardiovascular health by regulating the calcification of arteries, which is a critical element in the development of heart disease. Arterial calcification occurs when calcium deposits develop in the walls of arteries, making them stiff and narrow. Vitamin K2 helps activate matrix Gla protein (MGP), which helps prevent calcium from building up in arteries and other soft tissues. Research have revealed that low vitamin K2 levels are related with an increased risk of cardiovascular disease, whereas greater levels may protect against it. Hence, integrating vitamin K2 into the diet may considerably help heart health.

Vitamin K2 and Blood Pressure

Many research have studied the potential link between vitamin K2 and blood pressure. One study demonstrated that supplementation with vitamin K2 for eight weeks significantly lowered systolic and diastolic blood pressure in persons with high blood pressure. Another study indicated that higher vitamin K2 intake was associated with reduced blood pressure in postmenopausal women. Additional research has revealed that vitamin K2 may alleviate arterial stiffness, a risk factor for high blood pressure and cardiovascular disease. While additional research is needed, these findings imply that vitamin K2 may have a role in regulating blood pressure.

How Vitamin K2 Help Reduce Blood Pressure?

One potential mechanism by which vitamin K2 may help reduce blood pressure is through its modulation of vascular calcification. Arterial stiffness, frequently induced by calcification, can elevate blood pressure by lowering the diameter of the arteries and making it more difficult for blood to circulate. By activating MGP, vitamin K2 may help prevent calcium from accumulating in arterial walls, thus lowering arterial stiffness and boosting blood flow. Moreover, vitamin K2 may boost the function of the endothelium, the inner lining of blood vessels, which plays a critical role in regulating blood pressure. Several processes may contribute to vitamin K2’s possible blood pressure-lowering effects.

Vitamin K2 Foods

Vitamin K2 is predominantly present in animal-based diets, notably in fermented goods. The most plentiful source of vitamin K2 is natto, a traditional Japanese meal prepared from fermented soybeans. Additional food sources of vitamin K2 include fermented dairy products such as cheese, butter, and kefir, as well as organ meats such as liver and chicken. Lesser levels of vitamin K2 can also be found in eggs and certain types of fish, such as salmon and sardines. While plant-based foods contain vitamin K1, which has different health benefits, they generally do not contain large amounts of vitamin K2.

Recommended Dosage of Vitamin K2

There is no official recommended daily intake of vitamin K2 in many countries, however several organizations have produce recommendations base on available evidence. The European Food Safety Authority proposes a daily consumption of 75-90 micrograms of vitamin K2 for adults, while the Japanese government recommends a daily intake of 45-180 micrograms. Nevertheless, these recommendations are not universally embraced globally. It is crucial to highlight that vitamin K2 supplementation should be done under the advice of a healthcare practitioner, since excessive intake might potentially have detrimental consequences in some persons. Adding vitamin K2-rich foods into the diet is usually deemed safe and healthy.

Possible Benefits of Vitamin K2 for Blood Pressure

Several research have suggested that vitamin K2 supplementation may benefit blood pressure. For example, a study of 60 persons with hypertension found that supplementing with 180 micrograms of vitamin K2 daily for eight weeks significantly decreased both systolic and diastolic blood pressure. However, not all studies have revealed substantial effects of vitamin K2 intake on blood pressure. Further research is needed to fully understand the potential benefits of vitamin K2 supplementation for blood pressure and cardiovascular health. Supplementation should be done under the advice of a healthcare expert to ensure safety and efficacy.

Precautions and Possible Adverse Effects of Vitamin K2 Supplementation

While vitamin K2 supplement is typically regarded safe, excessive ingestion might bring undesirable effects. The most common adverse effect is nausea, which can include flushing, sweating, and dizziness. Vitamin K2 can interact with some medications, such as blood thinners, and should be avoided or used with caution by patients taking these treatments. Individuals with certain medical disorders, such as liver or renal illness, may also need to avoid vitamin K2 supplementation.



Vitamin K2 is an essential mineral for cardiovascular health. And evidence suggests that it may play a role in regulating blood pressure. While vitamin K2 can be found in animal-based foods, such as natto and cheese, acquiring enough from diet alone might be problematic. Ephuroalabs Vitamin K2 tablets offer an easy and effective solution to guarantee proper consumption of this crucial mineral. Nonetheless, it is crucial to consult a healthcare expert before starting any new supplement regimen to verify safety and efficacy. Adding Ephuroalabs Vitamin K2 into your diet can help your cardiovascular health and general well-being.
