For mild to moderate depression, clinical studies suggest that the following natural antidepressants, which are available in health food stores, are effective.
S-adenosyl-methionine (SAMe) elevates serotonin levels and balances other important neurotransmitters. Studies show that 70% of depressed patients who try SAMe notice improvements in mood within days. The recommended dose is 200-400 mg twice a day on an empty stomach, before breakfast and before lunch.St. John's Wort is an herbal antidepressant that is also very effective. Take 300 mg of a standardized extract twice daily with meals.
Another herbal antidepressant is 5-hydroxytryptophan (5-HTP). A dose of 30-50 mg on an empty stomach at bedtime.
