Dr. Feb's Analysis

Scientific Mechanism

This supplement utilizes a synergistic trio for cellular health. Vitamin D3 (Cholecalciferol) elevates calcium absorption in the small intestine, ensuring mineral availability. Vitamin K2 (MK-7), derived from natto, activates osteocalcin to bind calcium into the bone matrix and Matrix Gla-Protein (MGP) to prevent arterial calcification. Vitamin A supports cellular differentiation and immune function. The inclusion of organic Flaxseed Oil aids in the absorption of these fat-soluble vitamins.

Key Benefits

Key benefits include:

  • Promotes bone density and skeletal strength
  • Supports cardiovascular system and arterial flexibility
  • Enhances immune system function
  • Contributes to healthy skin and vision maintenance

Usage & Safety

Take 1 softgel daily with a meal containing dietary fat to maximize absorption. Do not exceed recommended dosage. Consult a physician if taking blood thinners (warfarin), as Vitamin K may alter efficacy. Keep sealed and out of reach of children.
