St. John’s Wort
This popular supplement has been shown to have antidepressive and antiviral properties. New research shows that St. John’s Wort may actually increase serotonin production. I have a tendency to be a little hyperactive. I have never been diagnosed with adult ADD, but I find that taking St. John’s Wort 3-4 times per week takes the edge off my being speedy very nicely.
Look for St. John’s Wort containing 0.3% standardized hypericin extract. Avoid if pregnant or planning pregnancy. May cause photo-sensitivity so avoid strong sunlight and other sources of ultraviolet light (like "tanning booths") when taking St. John’s Wort. Available in most health food stores.
