Women in Performance

At Momentous, we don’t just make supplements—we are redefining what women’s health support should be. Developed in collaboration with renowned expert ‪Dr. Stacy Sims‬ The Women's Three™️ is designed specifically for female biology, using a targeted AM/PM dosing protocol to maximize absorption, support daily energy, maintain strong, healthy bones, and promote long-term resilience.

Not The Industry Standard. The Momentous Standard®.

These three pillars guide every decision we make, from the products that make it into our portfolio to the ingredients that make it into our products.

Science:

We work with an ecosystem of experts to build formulas that solve real problems and meet your most impactful nutrient needs. We're not here to sell you an easy win, and we don’t follow trends; we follow science.

Sourcing:

We stop at nothing to source the most clinically-supported ingredients in their most bioavailable forms, from the cleanest origins possible: we know our suppliers and visit their facilities. That’s radical responsibility in practice.

Certification:

A label that can’t be verified isn’t worth your time or money. Every Momentous product is independently third-party certified to verify purity and label accuracy; if a production run doesn't pass, it doesn't hit your shelf.
