Vitamin K2 is best known for its role in vitamin K–dependent proteins involved in blood clotting and bone metabolism. Interest in brain health has grown because vitamin K compounds are also found in brain tissue and may be involved in cellular processes related to neuronal function. However, research on K2 and cognition is still developing, so it should not be presented as a proven treatment for memory loss or neurodegenerative disease. What Is Vitamin K2? Vitamin K is a fat-soluble vitamin family. Vitamin K1, or phylloquinone, is common in leafy green vegetables, while vitamin K2 refers to menaquinones found in some fermented foods and animal products. Common forms include MK-4 and MK-7. Their absorption, distribution, and time in the body differ, so supplement forms should not be treated as interchangeable. How Vitamin K2 May Relate to Brain Health Vitamin K participates in the acti...

Vitamin K2 is best known for its role in calcium metabolism, but researchers are also studying its possible relationship with brain health and cognitive function. The evidence is still developing, so K2 should not be presented as a treatment for memory loss or neurodegenerative disease. What Is Vitamin K2? Vitamin K2 is a fat-soluble form of vitamin K. Vitamin K1 is commonly found in leafy green vegetables, while K2 occurs in fermented foods and some animal products. Both forms are involved in important bodily processes, including blood clotting. Why Vitamin K2 Matters in the Body Calcium metabolism: K2 helps activate proteins involved in calcium handling. Bone health: It supports proteins that help bind calcium to bone. Cardiovascular health: K2 is involved in the activity of matrix Gla-protein, which is associated with calcium regulation in arteries. For related reading, see...

Research has found an association between low vitamin D levels and depressive symptoms, but supplementation is not a guaranteed treatment or replacement for professional mental-health care. What is vitamin D? Vitamin D is a fat-soluble vitamin involved in calcium absorption, bone health, immune function, and cell growth. The body can produce it after sun exposure, and it is also available from foods such as fatty fish, fortified dairy products, egg yolks, UV-exposed mushrooms, and supplements. How might vitamin D relate to depression? Researchers have proposed several possible explanations for the observed connection: Vitamin D may influence brain signaling, including pathways involved in mood. It may interact with inflammatory processes that are being studied in relation to depression. Limited sunlight in wint...
