Vitamin D3 5000
Nordic Naturals meets the gold standard for Vitamin D3 by using the preferred cholecalciferol form suspended in a high-quality extra virgin olive oil lipid matrix for superior absorption. The brand is a leader in transparency, offering batch-specific Certificates of Analysis (COAs) to verify potency and purity. While this specific formula lacks Vitamin K2, its clean ingredient profile and rigorous third-party testing justify its gold-tier status.
