The Best-Selling‡ Clinically-Backed Prenatal Multivitamin† Is Now Available at Costco

Finding a prenatal vitamin you can trust shouldn’t feel like a guessing game. That’s why Ritual created Essential Prenatal: a multivitamin built on transparency, science, and traceable ingredients—no shady ingredients, no proprietary blends, no guessing. Every capsule is carefully formulated to support women’s nutrient needs through preconception, pregnancy, and postpartum, with key nutrients in forms your body can actually use.*

Now, we’re making it even easier to access. Essential Prenatal is available in select Costco warehouses across the West Coast and online at sameday.costco.com. This partnership brings the same clinically-backed, Made Traceable® formula you know and trust to a bigger stage—at our most affordable cost per day.

Whether you’re newly pregnant, planning ahead, or simply looking for a reliable way to stock up, this is prenatal care that’s convenient, transparent, and designed for real life.

Quality Prenatal Care, Now More Accessible Than Ever

When Ritual launched, the goal was clear: create a prenatal multivitamin women could actually trust—one where the ingredients are traceable, every dose is science-backed, and nothing is hidden behind a proprietary blend. No shady ingredients. No guessing. Just the key nutrients that matter, in forms that work, with full transparency on where they come from and why they're there.*

That mission just got a bigger stage.

Ritual Essential Prenatal, our best-selling, clinically-backed prenatal multivitamin, is now available in select Costco warehouse locations across the West Coast and online at sameday.costco.com. Whether you're newly pregnant, actively trying to conceive, or planning ahead, this is the most cost-effective way to stock up without compromising on the quality Ritual is built on.

What Is Ritual Essential Prenatal?

Essential Prenatal is Ritual's flagship prenatal multivitamin, designed to support women through every phase of the prenatal journey, from preconception through postpartum.

What makes it different isn't just what's inside. It's their rigorous standard behind every single ingredient.

Each capsule is formulated with 12 key nutrients, including:

• Folate (as 5-MTHF): the bioavailable form of folic acid, designed to support neural tube development*
• Omega-3 DHA: sourced from microalgae to support healthy fetal brain development*
• Choline: a critical nutrient for supporting baby's cognitive function that many prenatals skip entirely*
• Iron: to support healthy red blood cell production throughout pregnancy*
• Vitamin D3: for supporting immune support and bone health*

Beyond the formula, Ritual's Made Traceable® standard means every labelled ingredient is sourced transparently—you can see where it comes from, who supplies it, and why its included. Every batch is third-party tested for heavy metals, microbes and allergens. What's on the label is what's in the capsule.

This is the exact same formula available on Ritual.com, now offered in an extended-supply bundle through Costco.

Why Pick Costco?

Here's what Katerina Schneider, Ritual's founder & CEO, had to say:

Costco's own commitment to product quality vetting makes them a natural fit for a brand built on transparency. This isn't just a new retail partnership, it's an extension of Ritual's core belief that high-integrity prenatal care should be available to every woman, at every stage.

Price & Value—Our Lowest Cost Per Day

At $48.99 for a 60-day supply (a 2-bottle bundle), the Essential Prenatal at Costco breaks down to approximately $0.82 per day, the most cost-efficient way to purchase Essential Prenatal anywhere it's sold.

For women who prefer buying in bulk and maximizing value per serving, the Costco bundle offers the best deal available. A 60-day supply means fewer reorders, less chance of running low during a critical window, and more peace of mind throughout your pregnancy.

How to Buy Ritual Essential Prenatal at Costco

You can purchase Ritual Essential Prenatal through Costco in two ways:

• In select Costco warehouses: Look for Essential Prenatal in the vitamin and supplement aisle at participating West Coast locations. Current warehouse availability includes stores in California, Utah, Nevada, Hawaii, Washington, Oregon, Alaska, Montana, and Idaho.

• Check online at sameday.costco.com: Search "Ritual Essential Prenatal" and enter your zip code to confirm availability in your area before making the trip.

How to Make the Most of Your Ritual Costco Purchase

The 2-bottle, 60-day format is built for women who want to plan ahead. Here's how to get the most out of it:

• Store properly. Keep bottles in a cool, dry place, away from humidity and direct sunlight to keep them fresh.
• Take consistently. Take 2 capsules daily as directed. Essential Prenatal's delayed-release capsule is designed to be gentle, even on an empty stomach.*
• Set a restock reminder. At the 45-day mark, check sameday.costco.com or your local warehouse to ensure you can reorder before running out. Running low mid-pregnancy is a stress you don't need.
• Build the habit. Pair your prenatal with a daily anchor: your morning coffee, brushing your teeth, or bedtime. Consistent timing supports better adherence over a 40-week pregnancy.

Because the bundle covers two full months, it's ideal for planning around key milestones: first trimester through the second, or second trimester through delivery.
