💡 Pro Tips for Taking Multivitamins

  • Take with food (especially fats) to improve absorption of fat-soluble vitamins (A, D, E, K)

  • Don’t mix iron and calcium at the same time — they compete for absorption

  • Stay consistent — results build over weeks, not overnight

  • Check with your doctor before starting if on medications or managing a condition

❌ When NOT to Take Multivitamins

  • If you’re already taking multiple single-nutrient supplements (risk of overdose)

  • If your doctor advises against it (e.g., for certain kidney/liver conditions)

  • If your diet is already nutrient-rich (you may not need extra)
