Most people evaluate a new supplement or habit by noticing how they feel, which is close to the least reliable method available. A modest amount of structure improves it substantially.
Why casual assessment fails
Several problems compound. Expectation shapes perception. Regression to the mean means you started when feeling unusually bad and improvement was likely anyway. Recall is reconstructive and biased toward confirming what you now believe. Other things changed at the same time - season, workload, sleep, stress. And there is no baseline, so improvement is measured against a remembered impression rather than a record.
Building a better test
Define one or two specific measurable outcomes before starting - hours slept, an afternoon energy rating, task completion, a timed cognitive task. Record a baseline for two weeks before changing anything. Change one variable at a time. Run for long enough that natural fluctuation averages out, generally four weeks minimum. Record daily at a fixed time, briefly. Where possible, have someone else hold the record so you are not looking at your own trend while generating it.

Look for a difference larger than your baseline variability, since if your energy ratings ranged from four to eight before the change, a six afterwards means nothing. Consider what else changed. Be willing to conclude nothing happened, which is the outcome people most often refuse. And if you want a stronger test, an on-off-on design - use, stop, resume - is more informative than a single period, though it requires patience most people do not have.
Key takeaways
- Regression to the mean explains much of the improvement people attribute to a new supplement
- Record a baseline for two weeks before changing anything
- Look for a difference larger than your normal baseline variability
- On-off-on designs are more informative than a single continuous trial period
