Before you swallow anything, talk to your doctor to rule out physical causes for your fatigue—and to make sure the vitamin or herb you're considering won't interact with any other drugs you're taking.
4 of 8 | Gotu Kola
How it Works
This leafy herb fights brain fatigue and strengthens blood vessels, which improves circulation, says Babal. Cautions
Headache, skin rash, and sunlight sensitivity may occur in rare cases. High doses can cause nausea. Forms
Add fresh gotu kola to salads, or use the liquid extract in a 1:1 dilution; the freeze-dried herb is less potent. Dosage
Potency varies, so consult the label. Bauman usually suggests 1/2 tsp of diluted extract 3 times daily.
