No supplement compensates for a week of poor sleep. Before changing what you take, it is worth being honest about the handful of habits that shape daily energy more than anything on a shelf.
Sleep, first and last
Consistency of timing tends to matter as much as total hours. Going to bed and waking within the same window each day is unglamorous advice, and it outperforms most interventions people try instead.
Movement that you will repeat
The best training plan is the one still happening in three months. Frequency beats intensity for everyday energy, and a short daily walk is not a consolation prize.
Where supplements fit
At the margins, and only once the basics are steady. That is not a reason to dismiss them — it is a reason to judge them against a realistic baseline rather than against a bad week.
