How it works
Supports vascular health and calcium regulation, indirectly benefiting brain function.
Overview
Vitamin K2 is primarily known for its role in directing calcium to bones and away from soft tissues, supporting cardiovascular health. Indirectly, this may benefit brain function by maintaining healthy blood vessels and circulation. While not a direct nootropic, it contributes to long-term neurological health as part of a broader nutritional profile.
