Product Overview

Vitamin D functions as a neuroactive steroid hormone with widespread effects on brain development, neurotransmitter synthesis, immune tolerance, and inflammation. Vitamin K2 (menaquinone-7, MK-7) works synergistically with vitamin D to support calcium regulation, skeletal integrity, and long-term vascular and neurological health.

This formulation provides a clinically relevant dose of vitamin D3 combined with the longest-acting and most bioavailable form of vitamin K2 to support sustained physiological effects.
