How long until it works?

Most users report effects after two to four weeks of consistent daily use. Give it at least that long before judging it.

Can I take it with antidepressants?

Not without asking a doctor or pharmacist. It can interact with SSRIs and other antidepressants and raise serotonin too much.

Yes. St. John's Wort can speed up the breakdown of hormonal contraceptives and reduce their effectiveness. Use backup protection or ask a pharmacist.

It can make skin and eyes more sensitive to sunlight. Use sunscreen and cover up if you spend time outdoors.

It is a supplement, not a prescription medicine. Evidence supports it for mild to moderate low mood; see a doctor for severe or persistent symptoms.
