How to remember to take your supplements every day.
Tie your supplements to something you already do every day, keep them where that happens, and log each one as soon as you take it. A reminder is a good backup, but a routine does most of the work. Here's how to set that up, what to do when you miss a day, and what the research says.
Why supplements are easy to forget
Most daily supplements give you no signal when you skip one. There's no symptom to jog your memory, the bottle looks the same either way, and one morning blurs into the next. So "did I take it today?" is a memory problem, and memory is exactly what a routine and a simple record take off your plate.
1. Anchor them to a routine
In psychology, a habit is an action that's triggered automatically by a cue it has been paired with, like putting on a seatbelt after getting into a car. Habit researchers sum up their advice for patients in one line: repeat a chosen behavior in the same context until it becomes automatic, and choose a time and place you encounter every day.[1] In the study behind much of this advice, people tied a new daily behavior to a single once-a-day cue in their own lives, such as "after breakfast".[1][2]
Good anchors are things you do every day, at home, without thinking:
- finishing breakfast
- sitting down for dinner
- brushing your teeth at night
- filling your shaker after training, for creatine
If a supplement should be taken with food, make a meal the anchor. The NHS, for example, says to take vitamin D (colecalciferol) capsules or tablets with your main meal of the day.[7] Your label or a pharmacist can tell you about yours.
2. Keep them where the anchor happens
If the anchor is dinner, keep the bottles where you eat, not in a bathroom cabinet two rooms away. Seeing the bottle at the right moment does the remembering for you. This is our practical advice rather than a finding from the studies above, but it follows the same idea of linking the action to a place.
Visible to you shouldn't mean reachable by children. Supplements that contain iron must carry an FDA-required warning that accidental overdose of iron-containing products is a leading cause of fatal poisoning in children under 6, and that the product should be kept out of their reach.[6] If children are around, a high shelf or a cupboard you open at that meal works better than the counter.
3. Make an if-then plan
"I'll take my supplements every day" is a goal. "When I sit down for dinner, I take my vitamin D and magnesium" is a plan that says when, where and how. Psychologists call these if-then plans implementation intentions. A meta-analysis of 94 independent tests found they had a medium-to-large effect on reaching goals.[3]
Write yours down and keep it specific:
- "When I finish breakfast, I take my multivitamin."
- "When I put my shaker in my gym bag, I add a scoop of creatine."
- "When I brush my teeth at night, I take my magnesium."
4. Log it the moment you take it
A record turns "I think I took it" into "I took it at 8:10". The habit researchers' leaflet for patients suggests a simple daily tick-sheet while a new habit forms.[1] Log right after you take a dose, not later: logging later is how days go missing. After a few weeks your record also shows patterns, such as always missing Saturdays, which tells you where the routine needs work.
Our guide on how to keep a supplement log covers what to write down, with a template.
5. Use one reminder as a safety net
Reminders can help. A 2016 meta-analysis of 16 randomized trials with 2,742 patients found that text-message reminders roughly doubled the odds of taking medication as prescribed (odds ratio 2.11). The authors caution that the trials were short and mostly relied on self-reported adherence.[4] A 2020 review of app-based interventions found a similar effect on self-reported adherence across nine trials and called for larger studies.[5] Both looked at prescription medicines, not supplements.
Practical tips:
- Set one reminder a little after your anchor, as a check rather than the trigger.
- Prefer a reminder that knows what you've already logged, so it only asks about what's left.
- If you keep dismissing it, move the anchor or the time rather than adding more alarms.
6. Plan for days that break the routine
- Weekends. If your anchor only happens on weekdays, such as a commute, pick a second anchor for weekends.
- Travel. Pack the next few days' supplements next to your toothbrush, so the anchor travels with you. Keep the label, or a photo of it, so you know exactly what you're taking.
- Shift work. Anchor to waking up or your first meal rather than a clock time.
- Stopping something. Remove or pause it in your tracker, so your reminder and your record stay accurate.
What if you miss a day?
For the habit, it isn't a big deal. In the habit study, missing the occasional opportunity didn't seriously impair habit formation: automaticity gains soon resumed after one missed day.[1][2]
For the dose itself, follow your label or your pharmacist. As one example, the NHS advice for vitamin D (colecalciferol) is to take a forgotten dose as soon as you remember, unless it's nearly time for the next one, and never to take two doses at the same time to make up for it.[7] Don't assume that applies to everything; other products can have different instructions.
How long until it's automatic?
In that study, 96 people chose a daily eating, drinking or activity behavior, such as eating fruit or going for a walk, and repeated it for 12 weeks. How automatic it felt rose quickly at first and levelled off after about 66 days on average, but the time it took varied from 18 to 254 days between people.[1][2] Simple actions, like drinking water, became automatic faster than more involved ones.[1] Swallowing a capsule is about as simple as it gets, but don't worry if you still need the reminder after a couple of months.
Pill organizer, alarm or app?
The best tool is the one you'll still use in three months. These are the usual options.
| Tool | Works well when | Gets awkward when |
|---|---|---|
| Weekly pill organizer | You take pills or capsules and want to see whether today's slot is empty. | Powders, drops and liquids don't fit, refilling it is another chore, and you lose the label unless you keep the original containers. |
| Phone alarm | You take one thing at one time and want zero setup. | It rings whether or not you've taken it, and it keeps no record. |
| Pill reminder app | You take medicines on exact schedules or want refill reminders. | Reminders are built around timed doses, which can be more than a few daily supplements need. |
| A supplement tracker such as mond (our app) | You take several supplements a day and want one-tap logging and a reminder that lists what's left. | It's one more app, and features differ: mond, for example, doesn't check interactions. |
For a closer look at specific apps, see our comparison of supplement tracking apps.
Doing it with mond
mond is a supplement tracker for iPhone, coming soon to the App Store. It's built around the steps above:
- Log each supplement in one tap from the app, a Home Screen widget, a Lock Screen or Control Center button (iOS 18 and later) or Siri.
- One daily reminder names what you haven't logged yet.
- Each supplement can have its own schedule, such as chosen days of the week or a cycle with planned breaks.
- The month calendar shows a ring for every day you took your stack, plus your streak, so patterns stand out.
- Forgot to log? Tap the day in the calendar and log it there.
mond is free to download, with an optional mond Pro. See how the supplement tracker works, join the waitlist, or open the web version.
When to talk to a professional
The FDA advises talking to your doctor, pharmacist or another health care professional before you start a dietary supplement, partly because some supplements interact with medicines or other supplements.[8] Two examples it gives: St. John's wort makes some medicines less effective, including birth control pills and drugs for HIV/AIDS, heart disease and depression; and warfarin, ginkgo biloba, aspirin and vitamin E can each thin the blood, so taking them together may raise the risk of internal bleeding or stroke.[9]
Bring a list of all your supplements and medicines to every appointment, with the doses and how many times a day you take them.[9] If you have side effects, stop taking the supplement and contact your health care provider.[10]

Common questions
What's the best time of day to take supplements?
The time you'll stick to, within what the label says. Some supplements are meant to be taken with food; others have their own instructions. If the label doesn't say, ask a pharmacist.
Should I take a missed supplement later?
Follow the label or your pharmacist. For vitamin D, the NHS says to take a forgotten dose when you remember unless it's nearly time for the next one, and never to take two at once.[7] Other products can differ.
How many reminders should I set?
Start with one, a little after your anchor. If you keep missing it, change the anchor or the time rather than adding more alarms.
Do reminder apps actually work?
For medicines, trials suggest reminders help: text-message reminders roughly doubled the odds of self-reported adherence in one meta-analysis, and apps showed a similar effect in another.[4][5] Neither studied supplements, and both relied mostly on self-reports, so treat this as encouraging rather than proven.
