What are the ingredients in Zenstral PMS™?

Each caplet contains 20 mg of Vitex agnus castus (.3% casticin), 200 mg of magnesium oxide (MgO), and 50 mg of vitamin B6 (pyroxidine). The Vitex agnus castus (VAC) compound used in Zenstral is casticin, a flavonoid from the chasteberry. This is the same substance used in the clinical studies that show Vitex agnus castus to be effective. Nearly all other products on the market standardize to agnuside, a terpene compound from the chasteberry tree.
