Dietary Supplement For the support of: Pms, Mood and Menopause Breast Tissue Estrogen Balance Breast and Hormonal Balance Brevail supplies lignans, a compound found in seeds, grains, beans, fruits, and vegetables. Research suggests that our bodies use plant lignans, now sparse in the modern diet, to safely and gently buffer and balance estrogens. Brevail was studied and developed to increase lignan concentrations in the body to match levels found in women who collectively demonstrate an extraordinary history of breast health and hormonal balance. Brevail is a one-of-a-kind plant extract supported by studies for safety and efficacy in women. Breast, Pms and Menopause Support Brevail is for all women interested in maintaining optimal breast health and/or, nutritional support for common Pms and menopausal discomforts - with just one capsule per day.
