What does it actually take to build and maintain strong bones? It's not as simple as popping a calcium supplement.
Dr. Chris Masterjohn breaks down how vitamins A, D, and K2 work together to regulate bone proteins like osteocalcin and matrix GLA protein — and why leaving out vitamin A undermines the whole system. We get into why collagen matters more than most people realize, how the balance between calcium and phosphorus can work for or against you, and why the hidden phosphorus in carbonated soda and ultra-processed foods may be doing more damage to your bones than solely a lack of calcium.
The big takeaway: it's not about hitting a checklist of nutrients. It's about the foods you eat and how they work together.
