Ritual offers multivitamins and protein powders that are formulated based on gender and stage of life. Ritual's products are third-party tested, and some carry the USP or Informed Sport seal.
One study found that Ritual's Essential for Women supplement significantly improved vitamin D and omega-3 DHA levels in healthy premenopausal women after 12 weeks of daily use (32).
However, it's important to note that the study has potential for bias because Ritual funded the study and multiple study authors were Ritual employees.
Additionally, because Ritual's multivitamins are designed to help bridge nutrient gaps in an otherwise healthy diet, the supplements aren't suitable for individuals who need a more comprehensive multivitamin.
