Over-the-Counter 'Focus' Supplements: What a Medication Review Should Cover

Before you add an over-the-counter “focus” product, write down everything you already take (prescriptions, over-the-counter medicines, vitamins, herbs, and caffeine), the exact label of the new product, and any symptoms you want to keep an eye on. Then hand that list to a pharmacist or your clinician and ask them to review it. The National Institutes of Health Office of Dietary Supplements (ODS) encourages people to talk to their health care providers, including pharmacists, about their interest in or use of dietary supplements. This guide gives you a worksheet to do exactly that, plus a fictional worked example so you can see what a filled-in version looks like.

The Short Answer: What to Bring

If you only have five minutes, gather these six things:

A photo or copy of the product's Supplement Facts label, front and back, including the “other ingredients” line.
A list of every prescription and over-the-counter medicine you take, with the dose and how often.
Every other supplement you use, including vitamins, herbs, and protein or energy powders.
Your usual daily caffeine from coffee, tea, soda, energy drinks, and pills.
A short note on your sleep.
Any symptoms you already have, or notice after starting something new.

Why a Medication Review Comes Before the Purchase

Supplements are regulated differently from medicines. NIH ODS states that medicines must be approved by the FDA before they can be sold or marketed, and that supplements do not require this approval. ODS also notes that supplements can interact with some medicines in ways that might cause problems. Its examples include vitamin K, which can reduce how well the blood thinner warfarin works, and St. John's wort, which can speed the breakdown of some medicines.

The FDA adds that manufacturers and distributors of dietary supplements are prohibited from marketing products that are adulterated or misbranded. That is a rule for companies. It does not tell you whether a given product suits your medicines or your health history, which is the question a pharmacist or clinician can help with.

ODS says you are most likely to have side effects from supplements if you take them at high doses, take them instead of prescribed medicines, or take many different supplements. A “focus” product can contain several ingredients, so reading the label closely matters.

The Visit-Prep Worksheet

Copy this into a note on your phone or print it. Part 2 follows the layout of the ODS form “My Dietary Supplement and Medicine Record,” which asks for the product name and active ingredients, how much, how and when you use it, start and stop dates, why you use it, and who told you to use it. The product-label, caffeine, sleep, symptom, and question sections are our additions for focus products and are not part of the ODS form.

Part 1: The Product You Are Considering

Exact product name and the company on the label.
Serving size and servings per container, as printed on the Supplement Facts panel.
Each ingredient with its amount per serving. Note whether the label lists a percent Daily Value or leaves it blank.
Whether any ingredient is a botanical (plant) ingredient, and the plant part listed.
Whether any ingredient sits inside a “proprietary blend” with only a combined weight listed.
The “other ingredients” line.
The directions on the label (how much, how often) and how much you actually plan to take.
Why you want it, in your own words.

Part 2: Everything You Already Take

For each item, record the following:

Name and active ingredients (prescription, over-the-counter medicine, vitamin, mineral, herb, amino acid, or other supplement).
The dose and how often you take it.
When you started, and when you stopped if you did.
Why you take it.
Who recommended it and how to reach them.
Any allergic reaction or other problem you have had with it.

Part 3: Caffeine and Stimulants

Coffee, tea, soda, and energy drinks on a typical day, plus the caffeine amount if the label lists it.
Caffeine in any pill, powder, or pre-workout product.
Whether the new product lists caffeine, and in what amount.
Any other ingredient on the new label that you are unsure is a stimulant. Circle it and ask.

Part 4: Sleep

Usual bedtime and wake time.
Whether you have trouble falling or staying asleep.
What time of day you plan to take the new product.

Part 5: Symptoms and Health Context

Symptoms you already have, such as racing heart, jitteriness, headaches, stomach upset, or anxiety, and when they happen.
Any health conditions you are being treated for.
Whether you are pregnant, trying to become pregnant, or breastfeeding.
Any procedure or surgery scheduled in the near future.

Part 6: Questions to Ask

Does anything on this label overlap with something I already take?
Is there any ingredient here I should not combine with my medicines?
Does my total daily caffeine look reasonable once this product is added?
Would the timing affect my sleep?
What symptoms should make me stop and call you?
Is there anything about my situation that means I should not use a product like this?

A Fictional Worked Example

The product, the person, and every number below are made up to show how the worksheet works. This is not a real product, a real patient, or a recommendation.

Imagine a person preparing for a pharmacy visit. Their Part 1 entry for a made-up product called “Example Focus Blend” reads:

Serving size: 2 capsules. Servings per container: 30.
Caffeine: 150 mg per serving.
L-theanine: 200 mg per serving.
A “Focus Complex” of three herbal extracts, 500 mg combined, with no individual amounts listed.
Label directions: 2 capsules daily. The person plans to take 2 capsules in the morning and 2 more in the afternoon.

Their Part 3 caffeine tally for a typical day:

Morning energy drink with 160 mg of caffeine listed on its can.
New product, taken as planned (2 servings): 2 x 150 mg = 300 mg.
Total: 160 mg + 300 mg = 460 mg.

The FDA describes 400 mg of caffeine a day, about two to three 12-ounce cups of coffee, as an amount not generally associated with negative effects for most adults, and notes wide variation in how sensitive people are to caffeine and how fast they eliminate it. Against that reference point, the example's 460 mg is something to raise with the pharmacist, and the number comes from the labels rather than a guess. The planned dose is also double what the label directs, which is another item for the list.

Three things the person would flag from this worksheet:

The planned caffeine total is above the FDA's 400 mg reference amount.
A second dose in the afternoon could matter for the sleep note, since the FDA lists insomnia or sleep disruption among signs of too much caffeine.
The three herbal extracts are bundled in a proprietary blend with no individual amounts, so the pharmacist cannot compare them against the person's medicines from the label alone. The person would ask the company for the amounts or the plant names, or ask whether to skip the product.

The worksheet does not decide whether the product is right or wrong for this person. It makes sure the pharmacist sees the full picture before that decision is made.

What the Label Can and Cannot Tell You

ODS explains that supplements carry a Supplement Facts label listing the active ingredients, the amount per serving, and other ingredients. Required information includes serving size, the list of dietary ingredients, amounts per serving, percent Daily Value where one is established, botanical names and plant parts, and, for proprietary blends, the total weight and the components. A blend that shows only a total weight limits what anyone can tell about the individual amounts.

A label also cannot tell you how a product will interact with your own medicines or health history. That is the part a pharmacist or clinician can review once they can see the label and your list side by side. If a label does not state a caffeine amount, or lists an ingredient you cannot identify, write that down as a question rather than assuming.

Who Should Speak With a Professional First

Because focus products vary so much, a conversation with a pharmacist or clinician is a good idea for anyone considering one. It matters most if you:

take any prescription or over-the-counter medicine;
are pregnant, trying to become pregnant, or breastfeeding (the FDA lists these among reasons to check with a provider about caffeine);
have a medical condition you are treated for;
already use several supplements;
have a procedure or surgery coming up (ODS advises talking with your provider about supplements you take before a procedure);
already have symptoms such as a racing heart, jitteriness, or trouble sleeping.

If you have severe symptoms after taking any product, get urgent medical help rather than waiting for a pharmacy visit. The FDA estimates that toxic effects such as seizures can occur with rapid consumption of around 1,200 mg of caffeine, and it warns that pure caffeine products can cause serious health consequences.

Your Next Steps

Fill in the worksheet with the product label in front of you.
Print or save it, and bring it to your pharmacist, doctor, or other health professional. ODS recommends sharing your record at all your visits.
Ask the questions from Part 6 and write down the answers.
If you start something and notice a problem, stop and contact your health professional. The FDA also accepts reports from consumers about problems with dietary supplements.
Update the worksheet whenever anything on it changes.
