Vitamin D3 125 mcg (5000 IU)
This product utilizes the superior Cholecalciferol (D3) form suspended in a high-quality lipid matrix (extra virgin olive oil) to ensure optimal absorption. While it lacks the Vitamin K2 cofactor and amber glass packaging identified in the gold standard, it earns a gold tier through exceptional value and Life Extension's industry-leading transparency, offering batch-specific Certificates of Analysis (COA) for every bottle.
