Research has shown that St. John's Wort extract may support positive emotional health. Each daily serving of Gaia Herbs' fresh St. John's Wort flowering buds delivers 1,350 mg of concentrated extract, with 2.7 mg of Hypericins — a dose consistent with that used in published research for providing nervous system support to promote a healthy mood.
