Understanding the Synergy: How D3, A, and K2 Work Together

Discover Allergy Research Group — Vitamin D3 (cholecalciferol) stimulates the production of calcium-binding proteins in the gut, enhancing calcium absorption. Vitamin K2 (menaquinone) activates osteocalcin, which binds calcium to the bone matrix, and matrix GLA protein, which inhibits calcium deposition in arteries. Vitamin A (retinyl palmitate or beta-carotene) supports immune cell function and helps maintain normal vision. Together, these three nutrients form a balanced foundation for bone health, immune balance, and overall wellbeing.*

Why Take Vitamin D3 and K2 Together?

Vitamin D3 and vitamin K2 work in synergy to support calcium metabolism. While D3 increases calcium absorption from the diet, K2 activates proteins that direct calcium to bones and teeth, away from soft tissues like arteries. This interplay is crucial for maintaining strong bones and a healthy cardiovascular system. Allergy Research Group Vitamin D3 Complete 5000 combines these nutrients with vitamin A, which also supports immune function and eye health, providing a comprehensive approach to daily wellness.*

What to Look For in a D3 + K2 Supplement

When selecting a vitamin D3 and K2 supplement, consider the form and dosage. Vitamin D3 as cholecalciferol is the bioavailable form the body undertake. For K2, menaquinone-7 (MK-7) is preferred due to its longer half-life, enabling once-daily dosage. Allergy Research Group Vitamin D3 Complete 5000 supplies 125 mcg (5000 IU) of D3 per capsule, along with vitamin A and K2 in a vegetarian capsule. The brand is committed to purity and third-party testing, ensuring a high-quality product.*
