DOUGLAS LABS - TQ for Women - 120 Capsule(s) - NPN: 80042100 -- TQ for Women is a combination of herbal extracts, including chasteberry, specifically formulated to help relieve premenstrual and menopausal symptoms.Hormones normally fluctuate during a woman's menstrual cycle. Research shows that premenstrual symptoms are associated with hormone imbalances in the second half of the cycle, including high estrogen and prolactin levels, as well as low progesterone levels.Menopause occurs in women in their late 40s or early 50s when fertility and menstruation are ending. Women may experience a drop in estrogen levels that can lead to undesirable symptoms, such as hot flashes, night sweats, changes in sleep, mood swings or other symptoms.Chasteberry contains active constituents that play a role in hormone activity, including support for normal prolactin, estrogen and progesterone levels. It has also been found to decrease the activity of androgens, such as testosterone. Through these actions, chasteberry helps normalize hormones and stabilize menstrual cycle irregularities. Studies have shown that chasteberry extract supplementation also helps mediate premenstrual symptoms, including mood, headache, bloating, and breast fullness. Chasteberry extract has also been shown to help relieve symptoms associated with menopause, such as hot flashes.
