Serena Williams is no stranger to breaking boundaries. From dominating tennis courts to launching fashion lines and investing in startups, she’s built a career defined by both excellence and reinvention. Now, the 23-time Grand Slam champion is adding yet another role to her already impressive resume: Women’s Health Advisor at Ritual, the wellness brand known for rethinking daily essentials with transparency and science at the forefront.
The announcement came on August 5, alongside another first for Ritual: the debut of Magnesium+, a functional mix drink formulated to support sleep, relaxation, and overall well-being. And true to form, Williams isn’t just lending her name to the project—she’s already a fan.
A Nighttime Ritual, Reinvented
Magnesium has been a buzzword in the wellness world for years, but Ritual’s approach takes the familiar mineral a step further. Magnesium+ is a two-in-one powder blend, flavored with tart Montmorency cherries, designed to be mixed into water and sipped in the evening.
The formula features Magnesium Bisglycinate, a bioavailable form that’s gentle on the stomach—a welcome alternative for anyone who’s experienced digestive discomfort from standard magnesium supplements. This thoughtful formulation makes the product accessible not just for elite athletes like Williams, but for anyone looking to improve their nightly routine.
The benefits are broad: reduced stress, improved sleep quality, eased muscle tension, and support for heart, bone, and nerve health. For women specifically, it may help with cramps and recovery during pregnancy or menstruation. The inclusion of tart cherries does more than elevate the flavor—they’re clinically studied for their ability to ease fatigue and promote restful sleep.
In short, Magnesium+ isn’t just another supplement; it’s a lifestyle tool, crafted with intention to meet multiple needs at once.
Why Serena Said Yes
For Williams, this partnership was as much about values as it was about product innovation. Transparency has always been a cornerstone of Ritual, founded in 2016 by Kat Schneider when she struggled to find a clean, vegan prenatal vitamin that wasn’t clouded by vague ingredient lists. That same commitment to clarity and science-backed formulations is what drew Williams to the brand.
“I have always taken ingredient quality seriously,” Williams said in a statement. “With Ritual, they’re transparent about what’s in their products and where it all comes from. I know I’m giving my body the best.”
Her enthusiasm is more than professional—it’s personal. As someone who has lived through the physical demands of professional sports, pregnancy, and motherhood, Williams understands the importance of fueling her body with products she can trust.
“I couldn’t be more excited to announce my new role as their Women’s Health Advisor,” she continued. “From their commitment to clinical studies to their product standards—I am excited for this new chapter with Ritual. Here’s to setting a new standard in women’s health, together.”
Setting a New Standard
Wellness is an industry often criticized for murky claims and flashy marketing. Ritual has made its name by challenging that status quo, focusing on rigorous clinical studies, ingredient traceability, and consumer education. The launch of Magnesium+ and Williams’ appointment as Women’s Health Advisor signal a bold expansion of that mission—one that prioritizes women’s health in every stage of life.
Williams’ involvement also brings visibility to the ways supplements can support not only athletic performance but everyday wellness. Her career has been defined by strength and resilience, but her message is clear: good health isn’t just for athletes—it’s for everyone.
The Future of Ritual
Since its founding, Ritual has gone from prenatal vitamins to a full line of daily essentials, each created with the same guiding principle: if it doesn’t meet the highest standard of transparency and efficacy, it doesn’t make it into the bottle. With Magnesium+, Ritual steps into the world of functional drinks—a natural extension of its mission to make wellness approachable, effective, and rooted in science.
And with Williams on board, the brand has a powerful advocate who embodies those ideals. Her voice adds weight not just to the product launch, but to the broader conversation about what women deserve from the wellness industry: honesty, quality, and solutions that truly work.
A Winning Match
For Williams, this new role is more than a title—it’s a continuation of her lifelong commitment to excellence, now aimed at empowering others to feel and live their best. For Ritual, it’s the next chapter in a story that began with one woman’s frustration and grew into a company redefining wellness on its own terms.
Together, they’re setting the stage for a new era where women’s health isn’t an afterthought—it’s the standard. And it begins, fittingly, with a simple evening ritual: a glass of tart cherry–infused Magnesium+ to unwind, recharge, and restore.
