Don’t Let Your Morning Coffee Wash Your Supplements Down the Drain!
That first cup feels like magic… but popping your vitamins right after? Science says it might be sending some of them straight out of your system.
Coffee’s caffeine, polyphenols, and tannins can interfere with absorption or speed up excretion of key nutrients, meaning you’re not getting the full bang for your buck.
Here are the 5 supplements to take AWAY from your brew (aim for at least 1 hour apart):
Iron – Polyphenols bind to it → up to 60-90% less absorbed! Especially important if you're low, plant-based, or menstruating. Pair with vitamin C instead.
Zinc – Similar binding issue → reduced uptake for immune & skin support.
Calcium – Caffeine increases urinary loss → less net benefit for bones over time.
Magnesium – Diuretic effect can flush it out; some forms may cause extra tummy upset with coffee.
B Vitamins (especially B1) – Water-soluble + faster urination = less retained for energy & nerves.
Timing isn’t about ditching coffee, it’s about making both work harder for you. Enjoy your ritual, just give those targeted nutrients a little space. Your body (and wallet) will thank you.
