Don't double up to catch up
A single missed day of a supplement is rarely a big deal, and taking two at once to compensate is generally not the answer. In most cases, taking it when you remember (if it is still the same day) or skipping to the next scheduled time is enough.
Medicines can have different rules than supplements, so for anything prescribed, check the label or ask your pharmacist rather than guessing.
Reducing the misses
If you are missing often, the fix is usually the routine, not willpower. Pillog reminds you at your set time, lets you check it off from the notification, and shows your month as a card so you can spot which days slip. It all stays on your phone, with no account.
Seeing the pattern often reveals a simple change — moving the time to a meal you never skip, for example.
