Which nutraceutical is shown to be frequently helpful in treating unipolar depression?

• A. Melatonin
• B. Vitamin E
• C. St John's wort
• D. Folate

Answer: (C)

St. John’s wort is the nutraceutical most consistently linked to antidepressant effects in mild to moderate unipolar depression. Its active components appear to influence brain monoamines by inhibiting the reuptake of serotonin, norepinephrine, and dopamine, which can help improve mood and lessen depressive symptoms. Clinical research has found it can be as effective as standard antidepressants for milder cases and often with a tolerability profile that some patients prefer. However, its efficacy is not as clear for severe depression, and it carries important cautions: it strongly induces liver enzymes, which can reduce the effectiveness of many medications (like birth control, anticoagulants, and immunosuppressants) and can contribute to serotonin syndrome if used with other serotonergic drugs. Other substances listed aren’t typically used as effective treatments for unipolar depression.
