Club members will be able to purchase a two-month supply (120 capsules) for $48.99 both in store and online, as well as same-day delivery.
“Costco has always felt like a dream partner for Ritual, because their internal bar for efficacy and scientific verification mirrors our own uncompromising standards,” said Katerina Schneider, founder and CEO of Ritual.
She added that beyond shared efficacy standards, the two companies see alignment in their commitments to advancing women’s health.
“For a decade, we’ve challenged the industry to stop treating women’s health as an afterthought and Costco’s new fertility-care partnership reflects the same conviction Ritual was built on: that pregnancy and women’s health deserve serious investment,” Schneider said. “Our regional test confirmed the demand for high-quality, clinically backed prenatals isn’t just real, it’s durable and now our nationwide expansion at Costco is proof that prioritizing clinical integrity drives category-defining growth.”
Clinical validation and consumer trust
Retailers like Costco have begun asking the questions many consumers do when it comes to understanding supplement efficacy. According to Schneider, those questions include: Does the specific ingredient dose and form in the product match what was studied? Was the finished formula analyzed or just individual ingredients?
Formulated with 12 essential nutrients delivered in a delayed release capsule to support the unique needs before and during pregnancy, Essential Prenatal includes omega-3 DHA, choline and bioavailable methylated folate to support fetal brain development, as well as D3, K2, magnesium and boron to support bone health.
Ritual said it has carried out five clinical studies across its product portfolio, three of which are published in peer-reviewed journals. The company has committed $5 million to complete clinical trials across its product line by 2030. Ritual said that level of scientific rigor sustains repeat purchase once a product is on a shelf, as demonstrated by sales at other retail outlets.
Nielsen data shows Essential Prenatal is the No. 1 best-selling prenatal SKU by revenue at Whole Foods Market and the No. 1 best-selling prenatal SKU by revenue nationwide at Target. Online, Ritual is the No. 1-selling pregnancy brand on Amazon.
“Our goal is to continue opening doors with retailers who share our commitment to evidence-based women’s health,” Schneider said. “Partners who, like Costco, see the value in treating this category with the seriousness and clinical rigor it deserves. As we look ahead, we’ll continue to prioritize those key strategic alliances that allow us to meet our customers where they already shop, without ever compromising on the standard of care we’ve spent the last decade building.”
Countering the naysayers
Ritual’s rise to becoming a successful women’s health company might not have happened had Schneider listened to her detractors. Nearly a decade ago when she was four months pregnant and raising Ritual’s first round of financing, members of the investment community told Schneider that women’s health category was too “niche.” Many of those investors decided to pass on financing her company even though Schneider, who came from a career in the investment world, knew them personally. It is projected that the women’s health market will grow to $75 billion by 2033.
“Being told women’s health was ‘niche’ became the loudest signal that the industry itself was broken,” Schneider said. “I heard some version of it more than a hundred times: that pregnancy was too small a market, that perimenopause was niche, that women’s health didn’t scale, or that I’d have to choose between building a company and building a family.”
She noted that for more than a decade reproductive and women’s health had been treated as a lifestyle category rather than a clinical one, which meant it was consistently overlooked for product innovation, clinical trials and retail shelf space.
“That disconnect, between the size of the need and how dismissively the industry treated it, is what kept me going. I wasn’t chasing a trend. I was solving a real problem,” Schneider said.
