Nutri Doctor lets you search for supplement products by their ingredients. You add the ingredients you want, optionally exclude ingredients you want to avoid, and the search engine returns products that match your criteria — across multiple merchants simultaneously.
Results are ranked to show you the fewest products needed to cover all the ingredients you're looking for, making it easy to find efficient, targeted combinations.
Type the name of an ingredient into the search box. A dropdown will appear with matching ingredients from our database — if an ingredient doesn't appear, it isn't in our index yet. Select an ingredient from the list to add it.
Once added, the ingredient appears as a tag with a green [ + ] symbol. Search results update automatically. You can add up to five ingredients at a time.
Tap or click an added ingredient tag once. The green [ + ] symbol changes to a dark red [ − ] and the label shows "Excluded." Results will automatically update to hide any products containing that ingredient.
This is useful if you have an allergy, sensitivity, or simply want to avoid a specific compound.
Each ingredient tag cycles through three states as you tap or click it:
| Tap / Click | Symbol | State | What it does |
|---|---|---|---|
| 1st | − | Excluded | Products with this ingredient are hidden |
| 2nd | × | Delete | Tap the delete button to confirm removal |
| 3rd | + | Added | Ingredient is added; results update |
To clear your entire search at once, tap the three-disk reset icon at the bottom right of the search box. It only appears when at least one ingredient has been added.
Tap or click the menu icon in the top right corner. You'll see a list of available merchants. Tap a merchant name to toggle it on or off — active merchants appear in green, excluded merchants in red. At least one merchant must remain selected at all times.
The current limit of five search conditions keeps results focused and manageable. If there is sufficient demand, this limit may be increased in a future update. You can request this — or any other feature — through the contact link below.
Product information — including ingredient lists, amounts, descriptions, and prices — is sourced directly from third-party merchant websites. Nutri Doctor does not manufacture, sell, or fulfil any products.
We update merchant site data periodically, but product formulations, availability, and prices can change between updates. The data displayed may not reflect the most current information.

Nutri Doctor does not require an account and does not collect your name, email, or any personally identifiable information.
We use Google Analytics to collect anonymized usage data — pages visited, search activity, session duration, device type, and approximate region. This helps us understand how the Service is used and how to improve it. Google Analytics sets third-party cookies for this purpose.

The best way to support Nutri Doctor is to use it and share it. When you click through to a merchant and make a purchase, we may earn a small affiliate commission at no extra cost to you. This helps cover the cost of running and improving the Service.
The best place for feature requests, bug reports, and public discussion is our GitHub repository — it keeps everything transparent and searchable:
