Your first 30 days. So the box doesn't end up in the cupboard.
You know how it goes: by week three the box is forgotten in the cupboard. Here is a simple plan for the first month: when to take it, what to note down, and how to decide what comes next.
The month, week by week
Before
Before you start
Read the label: composition, daily dose, warnings, storage. If you take medication, have a condition, are pregnant or breastfeeding, ask a doctor or pharmacist about this exact product.
1-7
Note where you start
In the evening you open the diary and move the three sliders for the day. If you already take a supplement, write down which one and follow its directions. Don't start several new ones at once just because they are in the same category.
8-14
Find your moment
Pick a moment that is already yours, like breakfast or dinner. Take it as the label says, then make your note. A missed note can stay missed. A missed dose? Follow the product's directions and don't make up for it on your own.
15-21
Look at the days side by side
This is the week the box usually ends up in the cupboard. Look over several days together and note what was different: a heavy workload, travel, a change in routine.
22-30
Decide for yourself what comes next
Gather your questions and compare your notes. Whether you carry on is up to you, not the calendar. If a complaint doesn't go away or gets worse, see a doctor.
The first entry takes a minute.
You can follow the plan with the diary alone, without buying anything. If you notice an unwanted reaction, stop taking it and see a doctor.
