Organize Supplement Label Amounts
Enter the labeled per-serving amounts for two products and multiply by the selected number of servings. Entries are processed only in this browser and are not sent in URLs or to the server.
Check the label’s serving size (for example, two tablets). Only identical ingredient names are added, and only g, mg and µg mass units are converted. A dash means the ingredient was not entered for that product; it is different from an entered zero. IU, DFE, RAE and different chemical forms are not automatically converted or merged. This result does not assess absorption, interactions, recommended or upper limits, safety or efficacy.

Worked example
These are fictional labels, not real products. First check what one labeled serving contains; enter how many such servings to calculate. The numbers are not a dose recommendation.
Product A
- Product name: Practice product A (fictional serving size: 2 tablets)
- Number of labeled servings: 2
- First ingredient: Vitamin C / 200 / mg
- Choose “Add ingredient”: Vitamin D3 / 10 / µg
Product B
- Product name: Practice product B (fictional serving size: 1 tablet)
- Number of labeled servings: 1
- First ingredient: Vitamin C / 0.1 / g
- Choose “Add ingredient”: Vitamin D2 / 5 / µg
After “Summarize amounts”: Vitamin C shows A 400 mg + B 100 mg = 500 mg total. Vitamin D3 shows A 20 µg and B “—”; Vitamin D2 shows A “—” and B 5 µg.
The label’s serving size (such as two tablets) differs from the number of servings entered. A dash means no entry for that product, not zero. This tool cannot decide whether any amount or combination is appropriate.
What to copy from the label
First check each product’s labeled serving size (for example, two tablets), then enter the ingredient name, amount and unit shown for that serving. The number of servings here is only a calculation scenario, not a recommended dose. Per-day directions and labeled serving size may differ; use the original label.
Limits of the total
Only the labeled mass of identically named ingredients is added. Different names, sources or chemical forms are not automatically treated as equivalent. IU, DFE, RAE, live organism counts and activity units are not converted. A smaller or larger total alone cannot establish deficiency, excess or safety.
Bring the information to a care visit
Keep the product name and label photo, actual use, and start or change dates in the existing blank record. If you take medicines, are pregnant or breastfeeding, or have a procedure coming up, show the label and list to a clinician or pharmacist. This tool does not check drug interactions.
