HCN Healer Handbook
“Hi there, I noticed you’re buying a variety of supplements today. It’s great that you’re proactive about your health. However, did you know that some vitamins can interact with each other? For example, taking magnesium and calcium together can actually make them less effective. It’s also important to consult your healthcare provider for personalized advice. Would you like more information on how to safely combine these supplements?”

Dosage and Timing
  • Always read labels for dosage and timing.
  • Consult healthcare provider for personalized guidance.
Vitamins Not to Combine
  • Magnesium and Calcium: Need balanced ratio for effectiveness.
  • Iron and Green Tea: Green tea reduces iron absorption.
  • Vitamin C and B12: High doses of C can affect B12 absorption.
  • Fat-soluble and Water-soluble: Take at different times for optimal absorption.

According to the 2017-2018 National Health and Nutrition Examination Survey, 57% of Americans more than 20 years of age take at least one dietary supplement.

Vitamins to Combine
  • Vitamin D and K2: Work synergistically for calcium absorption.
  • Magnesium and D3: Magnesium needed for D3 synthesis.
  • Copper and Zinc: Balance is key to avoid deficiencies.
  • Omega-3s and Vitamin E: May enhance heart health.
