The following list explains how the ingredients in Rituals Multivitamins for Women (both the 18+ and 50+ formulas) could promote better overall female hormone health: Vitamin D: May be linked to the production of certain reproductive hormones and the sex hormones estradiol and progesterone10 55 Vitamin E: Could potentially improve female fertility and reproductive health11 Folate: Essential for preventing birth defects in pregnancy and may both increase progesterone levels and lower the risk of anovulation (not ovulating)56 Vitamin B12: Optimal levels could improve ovarian health, fertility, and pregnancy outcomes12 Magnesium: May reduce premenstrual symptoms, such as cravings, depression, and anxiety (but magnesium performs a bit better with the inclusion of vitamin B6)57 Omega-3 fatty acids: Could improve fertility, reduce pregnancy complication risk, and potentially help with postpartum depression, menopause symptoms, and more58 Boron: Increases the bioavailability of sex hormones and vitamin D59 Vitamin K2: May influence estrogen metabolism, though most supporting evidence comes from preclinical research, with limited data in humans60 Insider Tip: Though the dose of boron in Rituals multis for women isnt particularly high (0.7mg is about the same amount youd get from a cup of grape juice or a medium apple), women with endometriosis may want to avoid supplementing with any of this trace mineral.61 Boron might act like estrogen, meaning it could worsen estrogen-sensitive medical conditions such as endometriosis.33 Pricing details Ritual operates on a subscription-only model through its website, meaning theres no option to make a one-time purchase directly from the brand
