Our verdict
Ritual's traceability and USP verification are genuinely best in class, and its own trial shows the vitamin D, folate and DHA doses raise blood levels. But at $33 or more a month you get nine nutrients, with no iodine or zinc and under half the iron most menstruating women need. It works better as a convenient vitamin D plus DHA supplement than as a complete multivitamin.

Ritual's Essential for Women 18+ is less a classic multivitamin than a targeted gap-filler. Two delayed-release capsules deliver nine nutrients: vitamin D3 from lichen (2,000 IU), methylfolate (1,000 mcg DFE), methylcobalamin B12 (8 mcg), chelated iron (8 mg), vitamin E, vitamin K2 as MK-7 (90 mcg), 30 mg of magnesium, boron and 330 mg of algae-derived omega-3 DHA, with the nutrient beadlets suspended in oil inside the capsule.
The brand's disclosure is exemplary. Suppliers and manufacturing locations are published for every ingredient, the product is USP Verified and Non-GMO Project Verified, and a 12-week randomized trial funded by Ritual (94 healthy women aged 21 to 40) found higher blood vitamin D (+43.7%), folate and red-cell omega-3 levels than placebo. That trial measured blood levels rather than health outcomes, and it used an earlier version with more magnesium and boron.
What is missing matters. There is no iodine, which the American Thyroid Association recommends at 150 mcg a day for women planning a pregnancy, and no zinc, selenium, vitamin A, vitamin C or B6. The 8 mg of iron covers less than half of the 18 mg RDA for women aged 19 to 50, and 30 mg of magnesium is only 7% of the DV.
At $37.50 one-time or $33 on subscription from Ritual (roughly $1.10 to $1.25 a day), you pay a premium for convenience, traceability and the DHA. Buyers and creators like the mint-scented bottle and easy-on-the-stomach capsules, but fishy burps from the DHA are a recurring complaint.
