Ashwagandha is generally well-tolerated when taken as directed. Momentous Ashwagandha is NSF Certified for Sport®, meaning it’s tested for purity, label accuracy, and banned substances—making it a trusted option for athletes and high-performers.

Yes. Every finished batch of Ashwagandha, Rhodiola Rosea, and L-Theanine, all three products in the Adaptogen Stack, is certified through NSF Certified for Sport®, a respected independent program that verifies label accuracy and screens for hundreds of banned substances. If a batch fails to meet these independent standards, it does not ship. We also take transparency a step further by publishing third-party test results via Light Labs on individual product pages and making Certificates of Analysis (COAs) available for every batch. We earn trust the hard way, by proving quality at every step, on every batch, with no shortcuts.

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.
