  • Our take on the St. John's Wort Herb

    Swanson St. John's Wort is a full-spectrum whole-herb supplement made from the leaves and flowers of the shrub, sold in vegan, gluten-free, non-GMO and Halal capsules. It is marketed for mood and emotional wellbeing, calmness under stress, and support of serotonin, dopamine and GABA. It is a popular pick among women for PMS and menopausal mood changes, where its phytoestrogenic properties are said to help with hot flashes and sleep disruption. Against rival single-extract St. John's Wort products, the whole-herb approach and the long brand history are its main selling points; the trade-off is that whole-herb potency varies and it is not a standardized hyperforin or hypericin extract.
