When is it best to take Tongat Ali?

Take Tongkat Ali in the morning or early in the day; its mildly stimulating effect may interfere with sleep when taken after 2 p.m. Andrew Huberman described taking 400 mg daily early in the day. 1

• 400 mg per day: Huberman reported taking 400 mg daily; a broader dose range discussed was 300–1,200 mg per day. 2
• After 2 p.m.: He said taking it after 2 p.m. starts to inhibit his sleep, so earlier is preferable. 3
• Continuous use and monitoring: Huberman described taking Tongkat Ali continuously and checking blood work, including liver enzymes. The guest said cycling likely isn't necessary, though he suggested an 11-month-on, one-month-off option as a precaution. 4
