How to Track Vitamins and Supplements With Your Medicines

Supplements are the part of a medicine routine people track least. They're bought without a prescription, started on a friend's advice and stopped when the bottle runs out, often without anyone telling their doctor. This guide shows how to track them with the same care as your medicines, and why that matters.

Why Supplements Deserve the Same Tracking

Supplements are common, and they can interact with medicines, so they belong in the same tracking system. The CDC reports that 57.6% of US adults used a dietary supplement in the past 30 days during 2017 to 2018.

Tracking them matters for two reasons.

Safety. The National Center for Complementary and Integrative Health notes that supplements may interact with your medicines or pose risks if you have certain medical problems or are having surgery. Your doctor and pharmacist can only check for those risks if they know what you take.

Consistency. If you've decided, with your doctor, that a supplement is worth taking, take it as planned. A vitamin D capsule is easy to forget because nothing reminds you of it.

The NCCIH also notes that "natural" does not always mean "safe," and the FDA makes the same point. A supplement is something you put in your body every day, and it deserves a place on your list.

Put Everything on One List

Keep supplements on the same list as your prescriptions and over-the-counter medicines, not in a separate note or your memory. MedlinePlus recommends a single list of everything you take, and counts vitamins, supplements and herbal products as part of it.

For each item, the National Institute on Aging suggests recording the name, the amount and the time you take it. For supplements, add:

• the brand and product, since strengths vary between products;
• why you take it, in a few words;
• who suggested it, your doctor, pharmacist or your own choice;
• when you started, and any planned end date.

Include the things people leave off: a daily multivitamin, omega-3 fish oil, a protein powder, herbal teas taken for health, a sleep aid you use now and then.

Keep one copy in your wallet and one at home, as MedlinePlus suggests, and bring it to every appointment. The FDA even suggests bringing your medicines and supplements in a bag.

Interactions to Ask Your Pharmacist About

Ask your pharmacist to check your full list, supplements included, whenever you add something new. The FDA warns that combining supplements and medicines can have dangerous and even life-threatening effects.

The FDA gives two examples:

• St. John's wort can make medicines for HIV/AIDS, heart disease and depression, organ transplant treatments and birth control pills less effective.
• Warfarin, ginkgo biloba, aspirin and vitamin E can each thin the blood, and taking them together may raise the risk of internal bleeding or stroke.

Surgery is another moment to review. The FDA notes your health care professional may ask you to stop some supplements two or three weeks before an operation.

Most reminder apps, Pillzy included, don't check interactions. What a tracker does is keep your list complete, so the person who does check, your pharmacist, sees everything. The NIA suggests using one pharmacy where possible, so its records can flag a problem.

Take Timing From the Label and Your Pharmacist

Set each supplement's reminder time from its label or your pharmacist's advice, not from general rules found online. Timing advice varies by product, and some supplements interact with each other or with medicines.

Questions worth asking about each supplement:

• Should I take it with food or on an empty stomach?
• Does it need to be kept apart from any of my medicines or other supplements?
• Does the time of day matter?

Our supplement directory covers cited general timing considerations for common products, including iron, calcium and magnesium. Use those pages as background for your pharmacist conversation, not as a replacement for it.

Once you know the timing, put each supplement into a time slot with your other medicines: morning, midday or evening. Fewer reminders are easier to follow. Our guide to the best time to take vitamins goes into timing in more depth.

Track Courses, Not Only Daily Doses

Record start and end dates for supplements you take for a limited time, so you know what you were taking and when. Many supplements are taken in courses rather than forever.

Common examples:

• Seasonal supplements, started in winter and stopped in spring.
• Pregnancy. Prenatal vitamins are taken for a set period; our pregnancy page covers routines during that time.
• Short courses your doctor suggested, for example after a blood test.
• Trials. Something you're trying for a few weeks to see if it helps.

For each course, note the start date, the planned end date and the reason. When you stop, record the date rather than deleting the item from your history. A doctor looking at a blood test result or a side effect may want to know what you were taking months ago.

Set a reminder for the end date too, or a review date, so a trial doesn't quietly become a permanent habit.

Note How You Feel, Carefully

Keep a short note of any changes after starting a supplement, but don't read too much into a few days. The NCCIH notes that rigorous evidence is often lacking for supplement claims: one review of 27 ingredients marketed for immune support found rigorous human studies for only eight.

What's worth noting:

• Possible side effects, such as stomach upset, with the date and how long it lasted.
• Anything that changed at the same time, such as a new medicine or diet.
• Results your doctor ordered, such as a blood test, if the supplement was meant to change one.

The NIA advises writing down side effects so you can report them accurately. That applies to supplements as much as to medicines.

Try not to judge a supplement on how you feel in its first week. Feelings vary from day to day for lots of reasons. A note gives you something concrete to discuss with your doctor or pharmacist when you decide whether to continue.

Setting Up Supplements in Pillzy

Pillzy tracks vitamins and supplements the same way it tracks medicines: each one gets a dose, a schedule and a reminder. That keeps your full list in one place.

To set it up:

1. Add each supplement with its name, amount and any label instructions. A photo of the bottle helps if you take several that look alike.
2. Choose a schedule: daily, weekly or custom, with one or more times a day.
3. Put supplements into the same time slots as your medicines where your pharmacist says that's fine.
4. Mark each dose as taken or missed when the reminder arrives.
5. Add notes for side effects, the reason you take it and any course end date.

Your history and statistics then show how consistently you take each one, and the full list is ready when a doctor or pharmacist asks.
