Supplement Timing Calculator
When you take a supplement changes how well it works. Fat-soluble vitamins (D, omega-3) absorb best with a meal, magnesium and melatonin suit the evening, and iron should be kept away from calcium, coffee and tea. Pick what you take to get a personalized schedule.
⚠️ Educational information only, not medical or nutrition advice. Timing guidance reflects general absorption principles, not a prescription for you. Some supplements interact with medications; check with a pharmacist or clinician about your own stack, especially if you take prescription drugs or are pregnant.
