Can you take supplements with coffee or caffeine?

Short answer: Many supplements are fine to take with coffee, but a few are better spaced apart — iron, for example, may absorb less when taken with coffee or tea. If you're unsure about a specific supplement, taking it with water and leaving coffee for later is a safe default.

Most are fine, a few aren't

For many everyday supplements, having them around your coffee is not a problem. The notable exceptions are things like iron, where compounds in coffee and tea may reduce how much you absorb.

When in doubt, taking a supplement with water and enjoying coffee an hour or two apart is an easy, safe habit.

Keeping the spacing simple

If you do need to separate a supplement from your coffee, a reminder makes it effortless. Pillog lets you set the exact time, check it off from the notification, and see your month as a card, all stored on your phone with no account and no ads.

Because interactions depend on the specific supplement, your pharmacist can tell you which of yours, if any, to keep away from caffeine.
