Find out if a supplement actually works. A structured way to run a fair test, avoid the placebo trap, and reach a clear keep-or-drop verdict. Includes baseline, weekly log, and verdict sheets. 11-page PDF.
Description
Most people take a supplement for months and never really know if it works.
They started it on a recommendation, felt vaguely better for a week, and kept buying it out of habit, while the money goes out every month. This log fixes that. It shows you how to run a fair test on any supplement, track the result honestly, and reach a clear keep-or-drop decision.
What This Is
The Supplement Effects & Review Log is an 11-page printable toolkit for finding out whether a supplement is actually doing anything for you.
The first half teaches you how to run a trial that gives a real answer, including the placebo and coincidence traps that fool people into keeping products that do nothing.
The second half gives you the sheets to run the test and decide. Do it once for each supplement you are unsure about, and you will stop paying for the ones that are not earning their place.
What’s Inside
How to run a fair test. The five rules that make a home trial actually mean something.
What to measure. The specific, trackable things worth recording, and the vague ones that only reflect your mood.
The placebo and coincidence traps. How to tell a real effect from expectation or a lucky week.
How long to test, and how to read the result. Fair trial lengths and a clear way to judge the outcome.
A baseline sheet, a weekly review log, and a keep-or-drop verdict page, plus a full worked example from start to finish.
Who It’s For
Anyone who takes supplements and wants to know which ones are genuinely worth it, instead of guessing. If you have ever wondered whether a product is doing anything, this gives you an honest way to find out.
The free calculators for checking cost and dose are in the Tools & Calculators section.
What Makes It Different
Most supplement logs are mood diaries. This one is built like a fair test. It sets a written baseline, controls for placebo and coincidence, and ends with a clear keep-or-drop verdict, so you get an answer you can trust. The guidance is based on official NIH and FDA government sources and on established principles of honest self-testing.
I judge a supplement by whether it genuinely does something, not by how it is sold, and this log lets you do the same for your own routine.
Free Tools to Use With It
When a supplement passes the test, confirm it is worth the money with the Cost Per Dose Calculator, and check that its dose is high enough to matter with the Study Dose vs Product Dose tool.

Important Note
This log is a personal record, not a medical tool. It does not diagnose anything and is not medical advice. Never test a medicine or stop a prescribed treatment to run a trial. If you have a health condition or take medication, speak with a doctor or pharmacist about your own situation.
Quick Answers
How do I receive it?
Instant digital download. You get access right after checkout, and you can print or fill it on screen.
How long does a trial take?
Usually four to eight weeks, depending on what you are testing. The guide gives fair lengths for different goals.
Can I test several supplements at once?
Better not to. The log explains why testing one at a time is the only way to know which one works.
