Introduction to Vitamin K2
In the ever-evolving world of health and wellness, certain nutrients often take center stage for their remarkable potential to support various aspects of our well-being. One such nutrient that has garnered significant attention in recent years is Vitamin K2, particularly in its highly bioavailable form known as Menaquinone-7 (MK-7). While many are familiar with the role of Vitamin K in blood clotting, the lesser-known benefits of Vitamin K2-MK7 extend far beyond this crucial function.
According to the National Health and Nutrition Examination Survey (NHANES), a staggering 97% of Americans are deficient in Vitamin K2, highlighting the significance of this overlooked nutrient. With its potential to impact bone health, cardiovascular function, and even cancer risk, Vitamin K2-MK7 deserves a closer look for those seeking to optimize their overall well-being.

Understanding Vitamin K2-MK7
What is Vitamin K2-MK7?
Vitamin K2, also known as menaquinone, is a group of compounds that share structural similarities with Vitamin K1 (phylloquinone), the primary form found in leafy green vegetables. However, Vitamin K2 exists in various forms, with Menaquinone-7 (MK-7) being one of the most bioavailable and beneficial variants.
Unlike Vitamin K1, which is primarily involved in blood clotting, Vitamin K2-MK7 plays a crucial role in regulating calcium metabolism and distribution within the body. This unique function has far-reaching implications for bone health, cardiovascular function, and potentially even cancer prevention.
Bioavailability and Absorption
One of the key advantages of Vitamin K2-MK7 is its exceptional bioavailability compared to other forms of Vitamin K. The MK-7 form has a longer half-life in the body, meaning it remains active for a more extended period, allowing for better absorption and utilization.
According to a study published in the journal Nutrition Research, MK-7 demonstrated a superior bioavailability and longer half-life compared to other forms of Vitamin K2, such as MK-4. This enhanced bioavailability contributes to the potential health benefits associated with Vitamin K2-MK7 supplementation.
Bone Health and Calcium Metabolism
Regulating Calcium Distribution
One of the primary functions of Vitamin K2-MK7 is its ability to regulate calcium distribution within the body. It works by activating a protein called osteocalcin, which binds calcium molecules and facilitates their transportation to bones, where they contribute to bone density and strength.
Conversely, Vitamin K2-MK7 also helps prevent the calcification of soft tissues, such as blood vessels and kidneys, by directing calcium away from these areas and towards the bones, where it is needed.
Promoting Bone Density and Strength
Several studies have highlighted the potential benefits of Vitamin K2-MK7 for maintaining bone health and preventing osteoporosis. In a three-year randomized controlled trial involving postmenopausal women, those who supplemented with Vitamin K2-MK7 experienced a significant reduction in age-related bone mineral density loss compared to the placebo group.
Another systematic review and meta-analysis published in the journal PLOS ONE concluded that Vitamin K2 supplementation, particularly in the MK-7 form, was associated with improved bone mineral density and reduced risk of fractures in various populations, including postmenopausal women and older adults.
Cardiovascular Benefits
Preventing Vascular Calcification
One of the most promising areas of research surrounding Vitamin K2-MK7 is its potential to support cardiovascular health by preventing vascular calcification. This process, where calcium deposits accumulate in the arteries and blood vessels, is a significant risk factor for conditions like atherosclerosis, heart disease, and stroke.
By activating the Matrix Gla Protein (MGP), Vitamin K2-MK7 helps inhibit the calcification of blood vessels, thus maintaining their flexibility and reducing the risk of cardiovascular events.
Improving Blood Lipid Profiles
In addition to its effects on vascular calcification, emerging research suggests that Vitamin K2-MK7 may also have beneficial impacts on blood lipid profiles. A study published in the journal Nutrients found that supplementation with Vitamin K2-MK7 significantly reduced levels of total cholesterol and LDL (low-density lipoprotein) cholesterol in participants with high cholesterol levels.
By potentially improving blood lipid profiles, Vitamin K2-MK7 may contribute to a reduced risk of cardiovascular diseases associated with elevated cholesterol levels.

Potential Cancer-Preventive Properties
Regulating Cell Growth and Proliferation
While research in this area is still emerging, several studies have suggested that Vitamin K2-MK7 may possess potential cancer-preventive properties. This potential is largely attributed to its role in regulating cell growth and proliferation.
In a review published in the journal Nutrients, researchers examined the available evidence on the anti-cancer effects of Vitamin K2. They found that Vitamin K2, particularly the MK-7 form, may inhibit the growth and metastasis of various cancer cells, including those related to prostate, lung, and liver cancers.
Antioxidant and Anti-Inflammatory Properties
In addition to its potential effects on cell growth and proliferation, Vitamin K2-MK7 may also exert cancer-preventive properties through its antioxidant and anti-inflammatory activities.
A study published in the journal Molecular and Cellular Biochemistry found that Vitamin K2-MK7 exhibited potent antioxidant and anti-inflammatory effects in cell culture models, suggesting its potential to protect against oxidative stress and chronic inflammation, which are known risk factors for various types of cancer.
Dietary Sources and Supplementation
Dietary Sources of Vitamin K2-MK7
While Vitamin K2-MK7 is present in certain fermented foods, such as natto (fermented soybeans), cheese, and some animal products, it is generally challenging to obtain adequate amounts through diet alone.
For instance, natto, a Japanese dish made from fermented soybeans, is one of the richest sources of Vitamin K2-MK7, providing approximately 1,000 micrograms per 100 grams. However, due to cultural and dietary preferences, natto may not be a practical or preferred source for many individuals.
Supplementation and Dosage
Given the difficulty in obtaining sufficient Vitamin K2-MK7 from dietary sources alone, supplementation has become a popular and convenient option for those seeking to optimize their intake. Vitamin K2-MK7 supplements are widely available in various forms, including capsules, softgels, and even gummies.
The recommended dosage for Vitamin K2-MK7 supplements can vary based on individual needs and desired health outcomes. Generally, dosages ranging from 100 to 200 micrograms per day are considered safe and effective for supporting bone health and cardiovascular function.
However, it is essential to consult with a healthcare professional, especially if you have any underlying medical conditions or are taking medications that may interact with Vitamin K2-MK7 supplementation.
