DaVinci ADK10 delivers the synergistic trio of fat-soluble vitamins A, D3, and K2 in a single physician-grade capsule — providing 10,000 IU of Vitamin D3 alongside therapeutic doses of Vitamin A (Retinyl Palmitate) and Vitamin K2 (Menaquinone-7/MK-7) for comprehensive bone, cardiovascular, immune, and hormonal health support. 90 capsules.The ADK10 combination addresses the fat-soluble vitamin triad that works interdependently: Vitamin D3 at 10,000 IU requires K2 (MK-7) to direct the calcium it mobilises to bone rather than soft tissue and arteries — a critical safety consideration at higher D3 doses. Vitamin A and D3 share nuclear receptors (RAR and VDR) and work cooperatively for immune system regulation, epithelial health, and hormonal balance. K2 MK-7's 72-hour half-life ensures consistent tissue K2 levels for continuous osteocalcin and MGP activation. At 10,000 IU D3, this is a physician-supervision formula for documented Vitamin D deficiency.
