Six Weeks In: The Check Almost Nobody Does

Take a supplement for 8 to 12 weeks before stopping to judge it. Write the review date and one measure down before your first dose, then decide on that date rather than drifting past it. The check takes 10 minutes and almost nobody does it.

Pick the measure before you start

The review fails when the question is vague. If what you want to know is whether you feel better, you'll find a way to feel better, because you bought the container and you want it to have worked. That is not dishonesty, it is how attention works. You notice the good mornings and file the others as exceptions.

Pick something countable. How many nights a week you wake before the alarm. Whether the 3pm slump is still there. Digestive comfort after a meal you usually avoid. One measure, written before the first dose, nothing added afterwards. A vague goal with a real date is still vague, and a second measure invented at week 6 is a way of moving the goalposts.

What the 8 to 12 weeks is actually doing

Long enough for an ingredient to reach steady state, short enough that you notice a flat 2 months. A 2011 trial of aged garlic extract in 51 people ran 12 weeks before reporting changes in the measures it tracked. Trials of omega-3 commonly run 16 weeks. The window is a convention rather than a law, which is why nobody should treat week 8 as a cliff edge.

Where the evidence is thinner, that window is the least you should demand. If nobody has run a trial on your ingredient at any duration, 12 weeks of your own observation is all you will ever have, which is a fair reason to buy the small size.

Stopping is a result, not a failure

Reviewing means opening the note and reading what you wrote before you started, not what you remember wanting. Two outcomes are both fine. If the measure moved, keep going and set the next date. If it did not move, stop. Not because the ingredient is bad, but because it hasn't earned the shelf space or the monthly charge.

A container you keep out of momentum is one you stop seeing. You stop taking it in week 9 and it sits there until you bin it 18 months later. I've done this with 4 containers. One was a collagen powder I kept buying for a year because the first month felt different. It wasn't.

Write the date down somewhere you already look

Mine goes in the same calendar as the dentist. 8 weeks out, one line: decide on this one. It works because the review lands in a slot I would otherwise have spent doing something else, and it doesn't depend on remembering. It also keeps the decision honest, since the measure I am checking was written before I cared about the answer.

People who cycle through supplements indefinitely are usually not careless. They never set an end point, so nothing gets evaluated and everything gets continued. A trial without a closing date is an expensive habit. Our own labels list the amount per serving and the count per container, which is enough to work out how many weeks one covers before you commit to the next.

Deciding to stop is a result, and writing the date down first is the only thing that makes it possible to tell the difference between a supplement that worked and one you simply kept buying.
