This site states this specific tip directly under its "Timing" routine step: same time each day. Taking it at the same time daily makes the habit easy to keep.
Worth reading "same time each day" as a general consistency principle, distinct from the specific breakfast-pairing suggestion — the two work together, but this tip would still apply even if you didn't pair the capsule with breakfast specifically.
Since this site is direct that cognitive nutrition is cumulative, worth reading this consistency tip as the practical habit that actually delivers on that cumulative framing over weeks and months.
