A medication review works best when you bring a complete, written list of everything you take — prescription drugs, over-the-counter medicines, and any dietary supplements, herbs, or “integrative health” products — along with the specific claims made about each supplement so your provider can check them against your medications. The two federal resources this article draws from are the National Center for Complementary and Integrative Health (NCCIH) and the National Institutes of Health Office of Dietary Supplements (ODS), both of which publish free tools built for exactly this conversation.
What “Integrative Health Claims” Actually Means
An “integrative health claim” is any statement made about a supplement, herb, or wellness product's effect on your body — for example, that an ingredient “supports” your immune system, “balances” blood sugar, or “detoxifies” your liver. These claims appear on product labels, in advertising, and in online reviews.
Under federal rule, a supplement label is allowed to describe how an ingredient may affect the structure or function of the body, but it cannot claim the product diagnoses, treats, cures, or prevents a disease — only an approved drug can legally make that kind of claim. When a structure/function claim appears on a label, it must be paired with a required notice: “This statement has not been evaluated by the Food and Drug Administration.” Understanding that distinction is the first step in evaluating any integrative health claim before a medication review.
Myth vs. Reality: Integrative Health Claims
Before your appointment, it helps to separate common assumptions from what federal health agencies actually say:
- Myth: “Natural” or “herbal” means a supplement is automatically safe to combine with prescription medication. Reality: Herbal supplements can change how prescription drugs work in the body. NCCIH specifically notes that St. John's wort can reduce the effectiveness of many prescription drugs, and other supplements can increase bleeding risk or affect how the body responds to anesthesia.
- Myth: A supplement label that says “standardized” or “certified” guarantees the product is high quality and consistent. Reality: NCCIH states that terms like these do not guarantee a product's quality or consistency, and that supplement labels do not always accurately reflect what is inside the product.
- Myth: If a supplement is sold in stores, it has been tested and approved the way prescription drugs are. Reality: Dietary supplements are regulated differently than drugs, and NCCIH reports that many supplements have not been tested in pregnant women, nursing mothers, or children — and that dietary supplements are linked to an estimated 23,000 emergency room visits each year.
- Myth: A multivitamin or immune-support blend has strong evidence behind broad health claims. Reality: NCCIH points to research showing multivitamins have not been shown to reduce the risk of cognitive decline, cancer, heart disease, or diabetes, or to extend lifespan, and a 2022 review found rigorous supporting evidence for only 8 of 27 commonly used immune-support ingredients.
Why the Evidence Has Limits — and Why That Matters for This Conversation
Evidence for integrative and supplement-based claims exists on a spectrum, from well-studied to essentially untested. Recognizing where a claim falls on that spectrum — before you bring it to a medication review — helps you ask sharper questions instead of accepting or dismissing a product outright. Our guide to the integrative medicine evidence hierarchy walks through how to weigh a systematic review against a single small study or a testimonial.
Two limits are worth naming directly. First, research quality varies widely: some ingredients have multiple large clinical trials behind them, while others rely on animal studies, small pilot studies, or traditional use alone. Second, even a well-studied ingredient can behave differently once it's combined with a specific prescription medication, a specific dose, or a specific health condition — which is exactly the kind of interaction a general product review can't predict, but your prescriber or pharmacist can help evaluate.
What to Bring to Your Medication Review: A Worksheet
Use this checklist to prepare before your appointment. NCCIH's core guidance is direct: “Take charge of your health—talk with your health care providers about any complementary health approaches you use.”
- A complete, written list of every prescription medication, over-the-counter medicine, vitamin, mineral, herb, and supplement you currently take, including dose and frequency. ODS offers a free printable form for this called “My Dietary Supplement and Medicine Record”, available in English and Spanish.
- The exact product name and brand for each supplement — not just the ingredient name — since formulations and doses vary between brands.
- The specific claim that led you to try it (for example, “advertised to support blood sugar” or “recommended online for sleep”), written in your own words, so your provider can address the actual claim rather than guessing at it.
- Any side effects, unusual symptoms, or changes you've noticed since starting a supplement, even if you're not sure they're related.
- Upcoming procedures or surgery — NCCIH advises discussing supplement use well in advance of any planned surgery, since some supplements affect bleeding risk or anesthesia.
- Questions about interactions specific to your own medication list, rather than general questions about the supplement category.
Questions Worth Asking at the Review
- “Based on my current medications, is there a known interaction with this supplement?”
- “Is there independent evidence for this specific claim, or is it mostly based on marketing?”
- “Would timing — taking this at a different time of day than my medication — reduce any risk?”
- “Is this supplement something I should stop before a procedure, and if so, how far in advance?”
- “Where can I look up more about this ingredient on my own?” (NCCIH and ODS both publish free, evidence-based fact sheets on individual ingredients, along with the FDA's Dietary Supplement Ingredient Directory and the Dietary Supplement Label Database for comparing what's actually listed on a product label.)

A Safety Note
Do not start, stop, or change the dose of any prescription medication based on a supplement claim without talking to the prescribing provider first. If you experience a severe reaction — such as difficulty breathing, chest pain, unusual bleeding, confusion, or signs of liver problems like yellowing skin or eyes — stop the product and seek emergency care or call your local emergency number immediately rather than waiting for a scheduled appointment.
