“Vitamin K is typically not a frequently supplemented vitamin in our society,” Lon Ben-Asher, MS, RD, LD/N with Pritikin Longevity Center He says Eat this, not that! “Vitamin K1 is the main form that can be supplemented compared to vitamin K2, however, most people get enough from their dietary patterns. While most of our intake of vitamin K1 comes from green vegetables, dark green leaves, vitamin K2 is found in red meat, organ meats like liver and eggs.”

Noting the “very promising impact” that vitamin K2 had on the brain, Mohamed El-Sherbiny, PhD, of AlMaarefa University in Saudi Arabia, who was also the lead author of the rat study, noted that “vitamin K2 may be proposed as a promising approach to attenuate age-related disorders and preserve cognitive functions in aging people.”

As for how vitamin K2 affects the brain, Ben-Asher says, “In addition to preventing bleeding by aiding in blood clotting, it reduces apoptosis (cell death) by protecting nerves from harmful substances and compounds that could reduce the risk of dementia/Alzheimer’s.”

Beyond that, Ben-Asher notes that vitamin K2 “plays an important role in bone healthit helps to strengthen the immune system and can help prevent cardiovascular diseases”, as well as being “essential for skin health”.

At the same time, Ben-Asher points to “the most important limitation of the study,” saying “there were no suggestions in eating behaviors.” Ben-Asher explains: “It is well known in human studies that the more saturated fat and cholesterol-rich foods we consume, the more consequential and detrimental the impact will be on our brain health, specifically accelerating the aging process and worsening cognitive abilities.” people consuming more animal-based foods and/or supplementing with a large concentrated exogenous source of vitamin K2 may have that impact.”

Ben-Asher also says that “we need to be careful when recommending vitamin K supplements, as they can interact with people taking blood-thinning medications, antibiotics, and antacids.” Finally, “there is no known maximum dose that is recommended for efficacy, as well as potential danger given that it is a fat-soluble vitamin and is not easily excreted from the body, especially in large amounts.”
