Follow your product's form
Because propolis is sold as drops, sprays, and capsules, the how-to depends on which you have — some are placed under the tongue, others swallowed. The label is your guide for that.
There is no strict best time of day, so pick a moment you can repeat. Some people take it with a meal simply because it is easy to remember.
An allergy note and a steady habit
One thing worth flagging: because propolis comes from bees, people with bee or pollen allergies should be cautious and check with a doctor before using it. If that is you, do not skip that step.
For everyone else, consistency is what makes a routine worthwhile — Pillog reminds you at your time, lets you check it off from the notification, and keeps your record on your phone with no account.
