The Short Answer: What to Bring
By MakeTimeForWellness.com Wellness Team
Before any health visit, bring a written list of every dietary supplement and medication you take. For each item, note the name, the amount, how often you take it, and why. The FDA recommends bringing this list to every visit — and suggests bagging up the actual bottles if a written list isn’t ready.
This isn’t paperwork for its own sake. A supplement can change how a medication is absorbed, processed, or cleared from your body, according to the FDA’s guidance on mixing medications and supplements. A complete list is what lets a health care provider spot a possible problem before it becomes one.
Why a Written List Matters More Than Memory
It’s easy to think of a daily vitamin or herbal capsule as separate from “real” medicine. Federal health agencies say otherwise. The FDA notes that dietary supplements can change the potency of a medication, meaning you may end up with too much or too little of the drug you actually need.
The National Center for Complementary and Integrative Health (NCCIH) adds a related caution: some products sold as supplements, particularly ones marketed for weight loss, sexual enhancement, or bodybuilding, have been found to contain prescription drug ingredients that aren’t listed on the label. If you’re only remembering supplement names from memory during a rushed appointment, details like this are easy to lose. If you’re weighing whether a specific combination is worth flagging before you even get to the visit, our guide on when to ask a pharmacist about supplements and prescription medicines walks through the most common interaction categories.
Neither agency frames this as a reason to avoid supplements. Both frame it as a reason to disclose them clearly.
What Belongs on Your List
NCCIH’s definition of a dietary supplement is broader than most people expect. It covers anything you take by mouth to supplement your diet, including vitamins, minerals, herbs or other botanicals, amino acids, enzymes, and extracts of these. In practice, that means your list should include:
- Multivitamins and single-nutrient vitamins or minerals
- Herbal or botanical products, including teas, extracts, tablets, and capsules
- Amino acid or protein-based supplements
- Fish oil, probiotics, and similar “everyday” products people often don’t think to mention
- Anything you take occasionally rather than daily
For each item, record the exact amount (for example, “500 mg” rather than “one pill”), how many times a day you take it, and roughly how long you’ve been taking it. If you’re not sure of the exact dose, bring the bottle or a photo of the label instead of guessing.
The Evidence Ladder: What’s Well-Documented vs. Still Uncertain
Not everything about supplement safety is equally well established. It helps to know which claims rest on solid ground and which are still open questions.
Well-documented, according to federal sources:
- The FDA states that St. John’s wort makes several drug categories less effective, including medicines for HIV/AIDS, heart disease, depression, and organ transplant, as well as birth control pills.
- The FDA also notes that warfarin, ginkgo biloba, aspirin, and vitamin E can each thin the blood, and combining any of these may raise the risk of internal bleeding or stroke.
- NCCIH confirms that dietary supplements may interact with medications or pose risks for people with certain medical conditions, or who are preparing for surgery.
Genuinely uncertain, according to the same sources:
- NCCIH states plainly that the amount of scientific evidence on dietary supplements “varies widely,” with a lot known about some products and very little about others.
- Supplements are not reviewed by the FDA for effectiveness before they’re sold, unlike prescription and over-the-counter drugs. A product being on store shelves doesn’t mean its safety or effectiveness has been independently confirmed.
- Many dietary supplements haven’t been tested in pregnant women, nursing mothers, or children, so the interaction picture for those groups is thinner than for general adult use.
This mix of “known” and “unknown” is exactly why a written list matters: it lets a pharmacist or provider apply current, specific guidance to your situation rather than relying on general assumptions about what’s “probably fine.”
Build Your List: A Step-by-Step Checklist
- Gather everything first. Collect every supplement bottle in your home, including ones you take occasionally, before you start writing anything down.
- Write the exact name and form. Note the full product name and whether it’s a tablet, capsule, powder, or liquid.
- Record the dose and frequency. Write the amount per dose and how many times a day you take it.
- Note why you take it. A short reason, such as “sleep” or “joint support,” helps a provider assess relevance quickly.
- Add how long you’ve taken it. New additions and long-standing habits carry different levels of relevance to a reviewer.
- Include your medications on the same list. The FDA specifically recommends bringing dietary supplements and medications together, not as separate lists.
- Flag anything new. If you started a supplement recently, mention it even if you don’t think it’s related to why you’re being seen.
- Bring the bottles if you’re unsure of details. The FDA suggests this as a practical backup when a written list isn’t complete.
When to Update or Re-Share Your List
A supplement list isn’t a one-time task. Update it whenever you start or stop a product, and bring the current version to any new visit, not just your regular provider. This matters especially in a few situations the FDA and NCCIH both call out:
- Before surgery. The FDA notes that some dietary supplements can interact harmfully with medications used before, during, or after a procedure, and a health care professional may ask you to stop certain supplements two to three weeks beforehand.
- If you’re pregnant, trying to conceive, or breastfeeding. NCCIH points out that many supplements haven’t been tested in these groups.
- If your health status changes. The FDA recommends telling a health care professional about any recent illness, in addition to supplement and medication use.
- If you see more than one provider. Each one may only see the list you hand them directly, so bring your full list to every visit, not just your primary provider.
Common Questions
Do I need to list a supplement I only take once in a while?
Yes. The FDA’s guidance is to bring a list of everything you’re “currently taking,” which includes occasional use, not just daily habits. An occasional supplement can still interact with a medication or matter before a procedure.
What if I don’t remember the exact dose?
Bring the bottle itself or a clear photo of the label instead of guessing. The FDA specifically suggests bringing bottles when a written list isn’t complete, so an exact label is a reasonable substitute for a precise number.
Does a multivitamin need to be on the list too?
Yes. NCCIH’s definition of a dietary supplement explicitly includes multivitamins, and the FDA’s list-building guidance doesn’t carve out an exception for products that seem “basic.”
What This Guide Can’t Do
This article is meant to help you organize accurate information, not to tell you whether a specific supplement is safe for you. A few limits are worth stating clearly:
- We can’t tell you whether your particular combination of supplements and medications is risky. That assessment depends on your full health history, which only a qualified health care provider or pharmacist can evaluate.
- An interaction not mentioned here doesn’t mean it’s been ruled out. NCCIH is direct about this: evidence on many supplement-and-medication combinations is still limited.
- Nothing here should be used to decide on your own to start, stop, or change any medication or supplement. If you have questions about a specific product, bring your list to a pharmacist or provider rather than making that call yourself.
If you ever experience a sudden, severe reaction after taking a supplement or medication, such as difficulty breathing, chest pain, or severe allergic symptoms, treat it as an emergency and contact local emergency services right away rather than waiting for a scheduled visit.
