Vitamin Basics & Tips

The combination of vitamins A, D, and K (ADK) represents a powerful nutritional synergy. Vitamin A supports vision and immune function, while vitamin D enhances calcium absorption and bone health. Vitamin K directs calcium to bones and teeth while preventing arterial calcification. Together, they create a "nutritional traffic system" that optimizes fat-soluble vitamin utilization.

Modern diets often lack sufficient vitamin A, with an estimated 50% of adults failing to meet daily requirements. Natural sources include liver, fish oils, and orange-colored vegetables containing beta-carotene. The Bulletproof formulation addresses absorption challenges by combining these vitamins with healthy fats, as they require dietary fat for proper assimilation.

Emerging research suggests ADK combinations may enhance metabolic efficiency and hormone regulation. Vitamin A supports thyroid function, while vitamin D acts as a hormonal precursor. Vitamin K2 (menaquinone), specifically used in quality supplements, activates proteins that improve cardiovascular and skeletal health. Always consult healthcare providers when combining supplements, as fat-soluble vitamins can accumulate in the body.
