Vitamin K is known for helping blood to clot and bones to stay strong. But researchers in Japan reveal that a new, improved version of vitamin K might actually help the brain grow new neurons. It means a vitamin we’ve known for decades could hold the key to healing damaged brains, offering a glimmer of hope for people facing conditions like Alzheimer’s and Parkinson’s.
At the Shibaura Institute of Technology in Tokyo, scientists have developed what they’re calling vitamin K analogues—essentially, lab-tweaked versions of the vitamin designed to boost its biological activity. By pairing vitamin K with retinoic acid (a substance linked to brain cell growth), the team created 12 hybrid compounds. One of them, later dubbed Novel VK, showed a stunning threefold improvement in encouraging neuron growth compared to natural vitamin K.
According to the research if neurodegenerative diseases cause neurons to die, they may also stimulate the brain to grow new ones. That’s exactly what Novel VK appears to do in early experiments.

Here’s what makes Novel VK stand out:
Boosted potency: It triggers much more neuron growth than regular vitamin K.
Crosses the brain barrier: Many treatments fail to reach the brain, but Novel VK makes it across with ease.
Stays stable in the body: It holds up well in both lab tests and live animal trials.
Activates key receptors: Novel VK binds to a receptor called mGluR1, which plays a vital role in brain cell communication.
Converts quickly to bioactive form: In mouse studies, it turned into MK-4 (the usable form) faster and more efficiently than natural K.
To understand how this works, the team dug deeper into gene activity in treated brain cells. They found that Novel VK triggers a chain reaction involving a receptor called mGluR1. This receptor is vital for proper communication between neurons—and is often impaired in diseases like Alzheimer’s. By activating it, Novel VK may be creating a more supportive environment for new neuron growth.

Right now, treatments for Alzheimer’s and similar diseases mostly manage symptoms. They don’t stop, let alone reverse, the destruction of brain cells. This study changes the game. If Novel VK can regenerate neurons in human brains the way it does in mice, it could offer a regenerative therapy—something that’s long been out of reach. Dr Yoshihisa Hirota, who led the research, sees the bigger picture: “A vitamin K-derived drug that slows the progression of Alzheimer’s could improve quality of life for patients and reduce the massive burden on families and healthcare systems alike.” As we move into an era where brain health is more important than ever, this ‘supercharged’ vitamin K might just be the unexpected hero.
FAQs on Vitamin K and its benefits:
1. What is Vitamin K?
Vitamin K is a fat-soluble vitamin essential for blood clotting, bone metabolism, and cardiovascular health. It helps the body produce proteins necessary for blood coagulation and bone strength.
2. What are the types of Vitamin K?
Vitamin K1 (Phylloquinone): Found mainly in green leafy vegetables.
Vitamin K2 (Menaquinone): Found in fermented foods and animal products, also produced by gut bacteria.
3. What are the main benefits of Vitamin K?
Blood clotting: Prevents excessive bleeding by helping blood to clot properly.
Bone health: Supports bone mineralization, reducing the risk of fractures.
Heart health: May help prevent artery calcification, promoting cardiovascular health.
4. What foods are rich in Vitamin K?
Leafy greens (kale, spinach, broccoli), Brussels sprouts, green beans, liver, fermented foods (natto), and some dairy products.
5. How much Vitamin K do I need daily?
Recommended daily intake varies by age, sex, and life stage. For adults, approximately 90 mcg/day for women and 120 mcg/day for men.
