What You'll Learn

Three things most supplement users get wrong

⚠️

The Stacking Mistakes

Most people unknowingly take supplements that fight each other. Iron and Calcium cut each other's absorption by up to 60%. Zinc and Copper compete for the same receptor. This sheet maps every conflict.

The Timing Science

Fat-soluble vitamins (D, K, E, A) need dietary fat to absorb — taking them fasted is nearly pointless. Magnesium before sleep improves sleep quality. Timing is not marketing. It's physiology.

🧬

The Synergy Pairs

D3+K2 together increase bone mineral density beyond either alone. Vitamin C triples iron absorption. Magnesium activates Vitamin D. These aren't tips — they're documented mechanisms with PubMed citations.
