Made from a brown berry from a chaste tree, Chasteberry is a herbal extract; it's a flowering shrub indigenous to the Mediterranean, Asia, and North America. Chasteberry also has a botanical name, vitex agnus-castus, often called vitex for short. Vitex raises progesterone levels and elongates cycles which are shortened because of luteal phase deficiency, a prominent cause of infertility in women.
Since Chasteberry reduces prolactin, using it as a supplement to reduce the quantity of prolactin is excellent, which increases in people experiencing stress. After using the supplement for three months, one study showed that people are twice as likely to get pregnant.
The recommended daily dose of chasteberry is 500 to 1000 mg of dried berries or one to four mL tincture to improve ovulatory factors affecting fertility. Side effects of Chasteberry are usually mild, causing headache, nausea, gastrointestinal disturbances, and itching.
Nature's Way Vitex Fruit, Nature's Answer Chasteberry, and Morphogen Chasteberry are three reputable brands that carry the correct dosages of the herbal extract to impact fertility positively.
