Supplements for Fatigue

The prophet (peace be upon him) gave us a prescription for obtaining strength, (scholars said it's for any kind of strength) before you sleep, you say:
Sub-ha-na-Allah 33 times, Al-ham-duli-llah 33 times, and Allahu-ak-bar 34 times.

It helps if you also maintain a healthy lifestyle with diet, exercise and sleeping habits. Here is a related article from Dr. Weil about: Supplements for Fatigue

If you feel worn down or are lacking energy due to a hectic schedule and day-to-day stressors, learn how to fight fatigue naturally. Taking a few minutes for yourself and doing simple breathing exercises can be helpful, as can daily moderate exercise and getting adequate rest.
