The full picture
Search the NIH Dietary Supplement Label Database, pick your product, and the entry carries its published Supplement Facts panel. That panel is what lets its nutrients join your day.
Supplement tracking
Track the supplement you actually take.
Match supported products to their published label and keep the dose and the ingredient panel with the entry. Log when you take it, and let known nutrients join the rest of your day.
Requires Loopa Premium Medication tracking is free and separate.

Why it matters
A shelf of bottles is not a record
Most people taking supplements could not tell you the dose of half of them without going and looking. Most could not tell a clinician what was in the multivitamin at all. Matching a product to its published label means the entry carries the panel, so the answer is on a screen instead of in a cupboard.

Two kinds of entry, and Loopa is clear about which
The difference decides what the app can tell you afterwards.
Still a real supplement
Anything not in the database, or anything you would rather enter by hand. You get the name, the dose, the schedule and the reminders.
Guess what is in it
A hand-typed name contributes no nutrient values at all. Inferring a panel from a product name would put invented numbers in your nutrition record, which is worse than an honest blank.
Where the numbers come from
Where a supplement entry’s numbers come from
From a product recordA matched product’s Supplement Facts panel, as published to the NIH label database by whoever makes it.
You entered itYour dose, your schedule, and every product you typed in yourself. Also every day you marked as taken.
Published guidanceThe nutrient targets a matched supplement counts toward, which are the same published Dietary Reference Intakes the food side uses.
Nutrients
A matched label can count toward your day
The 15 micronutrients Loopa derives from food already exist. A matched supplement joins them.
Per day marked taken
Loopa counts one serving for a day you marked as taken. It does not multiply a free-text frequency into a number, because turning “twice daily” into an intake figure is inventing one.
As the food
Your vitamin D from a capsule and your vitamin D from salmon land in the same place.
The 15 nutrientsIf there is no panel
A hand-typed supplement is tracked and reminded about, and contributes no nutrient values. That is the honest answer rather than a flattering one.
What the interaction check covers, and what it does not
Supplements you add are included in Loopa’s interaction check, which reads FDA-approved drug labeling. That is where supplement interactions are described: a drug label saying something about St John’s wort, or calcium, or vitamin K. So the check finds supplement-with-medication, and also medication-with-food, alcohol and caffeine.
It does not check supplements against each other. Drug labeling does not describe those combinations, and Loopa has no supplement-to-supplement source behind it. The app and the clinician share report say so, and so does this page.
Loopa never says a combination is safe, and nothing found is not the same as nothing there. A pharmacist can answer what this cannot. How the alerts work.
Two features, one screen
Medications are free. Supplements are Premium.
They sit together in the app because that is where a member expects them, and they are different features with different tiers.

FAQ
Questions about supplement tracking
Including the one about what the interaction check really covers.
Is supplement tracking free?
No, it is part of Loopa Premium. Medication tracking is a separate feature and it is free, including its interaction alerts. Removing a supplement you added stays free so a lapsed account can still clear its own list. Medication tracking.
Where does the label information come from?
The Dietary Supplement Label Database published by the National Institutes of Health, which holds more than 200,000 product labels. Loopa keeps its own copy and checks NIH for a new export monthly. NIH publishes irregularly, so most of those checks find nothing new, which is normal rather than a failure.
What if my supplement is not in the database?
Type it in yourself. You get the name, the dose you take and the reminders, exactly as with a matched product. What you do not get is the nutrient panel, because Loopa will not invent one from a name.
Do my supplements count toward my daily nutrients?
When the product is matched to a published label, yes: its listed nutrient values join your day alongside the 15 micronutrients from food, counted once for the serving you marked as taken. A hand-typed supplement contributes nothing, deliberately, because a guess at what is in a bottle is worse than a gap.
Does Loopa check my supplements for interactions?
It checks them against your MEDICATIONS, using FDA-approved drug labeling, which is where supplement interactions are actually described. It does not check supplements against each other: that source does not cover those combinations, and Loopa has no supplement-to-supplement database behind it. The app, the clinician share report and the knowledge base all say so.
Is the interaction check free?
The check itself is, and it lives with medication tracking. Adding a supplement so it can be checked is the Premium part, so a fair summary is: checking your medications is free, and getting your supplements into that check needs Premium.
What does the adherence figure mean?
What you logged, over seven days or thirty. It is a record of the days you marked something as taken. It is not evidence that you took it, and no app can produce that.
Do reminders log the dose?
Yes. Mark a reminder complete and the dose is written to your log, so you are not doing it twice. Reminder times come from the time of day you set on the supplement.
Do supplements appear in the clinician share report?
Yes, with your regimen and your logging record. The clinician share report is a Premium feature. Supplements are not in the raw data export.
