Spreadsheets are powerful because they can model almost anything. That is also the problem. A supplement tracking spreadsheet only works if you design the tables, formulas, reminders, review logic, and error checks yourself.
Google Sheets, Excel, and Numbers are excellent general tools. Google describes Sheets as collaborative spreadsheets for managing, visualizing, and analyzing data 1. Microsoft describes Excel as a grid of cells that can hold numbers, text, and formulas, then be sorted, filtered, tabled, and charted 2. That is real power. It is not the same as a supplement tracker that already understands stack definitions, dose windows, skipped doses, and review decisions.
Comparison disclosure
This is an Unfair-owned comparison. We build Unfair and are comparing it against spreadsheet workflows from a supplement-tracking point of view. Spreadsheet feature observations were checked from official Google, Microsoft, and Apple pages on May 6, 2026.
Methodology
We compared a purpose-built app against the realistic spreadsheet a serious user would maintain for more than one month.
| Criterion | Spreadsheet workflow | Unfair workflow |
|---|---|---|
| Setup | User designs columns, formulas, and review sheets | App provides supplement, stack, dose, timing, and review structure |
| Daily entry | Manual row entry or form | Purpose-built dose logging |
| Reminders | External calendar, task app, or manual habit | Built into the supplement workflow |
| Error control | Formula discipline and validation rules | Structured fields reduce entry drift |
| Review | Pivot tables, formulas, charts, and manual interpretation | Stack review with adherence and response labels |
| Flexibility | Very high | Focused on supplement workflows |
| Maintenance | High for multi-stack use | Lower once the stack is configured |
Feature comparison
| Workflow | Strength | Source-backed feature base | Constraint |
|---|---|---|---|
| Google Sheets | Collaboration, tables, filter views, comments, formulas, AI-assisted spreadsheet creation | Google describes online collaborative spreadsheets, tables, comments, permissions, formulas, and analysis features 1 3 | No built-in supplement model or dose reminder |
| Microsoft Excel | Tables, formulas, sorting, filtering, charts, and deep desktop analysis | Microsoft documents formulas, tables, filtering, sorting, conditional formatting, and charts 2 | No built-in supplement workflow |
| Apple Numbers | Apple-device spreadsheet workflow and export options | Apple Support describes Numbers support and exporting spreadsheets to Excel, CSV, and PDF formats 4 | No built-in supplement workflow |
| Unfair | Supplement stack logging, dose windows, outcome labels, review decisions | Unfair-owned workflow | Less open-ended than a blank spreadsheet |
Decision table
| Choose spreadsheets if | Choose Unfair if |
|---|---|
| You enjoy building your own tracking system | You want the structure ready on day one |
| You need custom formulas beyond the app workflow | You want fewer manual fields |
| You are analyzing an exported history | You are logging daily doses |
| You want full control over columns and charts | You want dose windows, adherence, and response labels together |
| You can maintain formulas without breaking them | You want stack review without spreadsheet upkeep |
The spreadsheet trap
The first version of a supplement spreadsheet is usually elegant. Date, supplement, dose, time, status, notes. Then real life arrives. You need a skipped-dose state, a late-dose state, a dose change, a new stack version, a cycle window, a confounder column, an outcome scale, a weekly summary, and a way to prevent accidental duplicate entries.
Spreadsheets can handle all of that. The cost is upkeep. Every new rule becomes a column, formula, validation list, or chart. If you like that work, spreadsheets are a fine archive. If you do not, the spreadsheet becomes another abandoned tracker.
A minimum viable supplement spreadsheet
If you do use a spreadsheet, keep it narrow.
| Column | Example | Rule |
|---|---|---|
| Date | 2026-05-06 | One row per dose event |
| Stack | Sleep v1 | Use a fixed dropdown |
| Supplement | Magnesium glycinate | Use standard names |
| Dose | 200mg | Include unit |
| Planned window | 9 PM to 10 PM | Do not use vague "night" labels |
| Actual time | 9:37 PM | Leave blank only if skipped |
| Status | Taken | Taken, skipped, late, changed |
| Outcome | Sleep onset 22 min | Use a fixed outcome format |
| Context | Travel day | Keep notes short |
That spreadsheet can support a basic weekly review. It still will not warn you about overlap, preserve stack versioning automatically, or prompt a review when the cycle ends.
How Unfair fits
Unfair is the better day-to-day system when you want less spreadsheet work. It turns the common columns into app structure: stack, dose, timing, status, response, context, and review. The user still makes the decision, but the data arrives in a shape that makes the decision easier.
Spreadsheets still have a place after export. They are useful for custom charts, long-term archival analysis, clinician summaries, and unusual formulas. The best workflow is often Unfair for capture and review, then spreadsheet export for deep custom analysis.
