Our Science
Most supplements ask you to take their word for it. We'd rather show our work. Here's exactly how a Seya formula is built, tested, and held to account, from the first ingredient to the final batch.
Why we do it differently
Nearly half of women don't trust the supplements they take. They have good reasons. Three of them, specifically.
Most formulas use a generic, male-derived reference point. Women's metabolism, hormones, and enzymes work differently, and a one-size-fits-all dose ignores that.
Proprietary blends let brands list ingredients without listing amounts. It's how a formula can look impressive while under-dosing the thing you actually bought it for.
"Clean" and "science-backed" are easy to print and hard to verify. Without third-party results, they're marketing, not evidence.
Pillar one
For most of research history, "the body" meant the male body. Studies were run on men, and doses were scaled down for women as if the only difference was size. It isn't. Hormones shift across the month and across a lifetime. Iron needs, muscle physiology, and how the body processes nutrients all differ.
So female physiology is our starting point, not a footnote. We choose ingredients and doses with a woman's body in mind, and we design formats that fit a real daily routine. Built for her, from the first ingredient.
The Seya method
Every formula moves through the same path before it earns a place in your morning.
01
We start from female physiology and choose ingredients with a clear rationale, reviewed alongside our scientific advisors.
02
We select bioavailable forms your body can actually absorb, not just the cheapest version of a nutrient.
03
Every active ingredient appears on the label with its exact amount. No proprietary blends, no fairy dusting.
04
An independent lab verifies every batch, and we make the certificate of analysis available to you.
Pillar two
The difference between a supplement you can trust and one you can't usually comes down to what's printed on the back.
Pillar three
Every ingredient earns its place. Here's the thinking behind our launch formulas. Exact amounts appear on each product's Supplement Facts.
Fiber Support
A soluble-fiber blend to help feed the good bacteria in your gut, paired with ginger for digestive comfort. Built to support regularity without the grit.
Creatine
The most-studied form of the most-studied performance ingredient, in a daily dose designed to support strength and muscle as part of an active routine.
Hormone Support
A well-absorbed form of magnesium alongside clinically informed botanicals, chosen to support cycle balance and a calmer, steadier day.
Pillar four
Trust requires receipts. Every batch is verified at three points before it ships, by an independent lab we don't control.
Stage one
Every incoming ingredient is checked for identity and purity before it enters the formula.
Stage two
Made in an FDA-registered, cGMP facility, with checks through the manufacturing run.
Stage three
A third-party lab confirms potency and screens for heavy metals and contaminants.
We publish a certificate of analysis for every batch, so you can check identity, potency, and purity for the exact product in your hand. Radical transparency means showing the receipts, not just promising them.
The short list
Just as important as what goes in. You won't find any of these in a Seya formula.

Straight answers
It means an independent lab, one we don't own or control, verifies each batch for identity, potency, and purity, and screens for heavy metals and contaminants. We publish the resulting certificate of analysis so you can read it for the exact product you bought.
It means we design with a woman's physiology as the reference point, choosing ingredients, forms, and doses with female metabolism and hormones in mind, rather than scaling down a formula built and tested on men.
A proprietary blend lets a brand list ingredients without disclosing how much of each is inside. That makes it impossible to know whether you're getting a meaningful amount. We list every active ingredient with its exact amount, so there's nothing to guess.
We formulate with ingredients that have a body of published research behind them, and we're transparent about the difference between ingredient research and a study on a specific finished product. We won't call a product "clinically proven" unless a study supports that exact claim. Where the science is still emerging, we say so.
Yes. Every batch is screened for heavy metals such as lead, arsenic, cadmium, and mercury, measured against a full daily serving, as part of our third-party testing.
Our gummies are manufactured in the United States in an FDA-registered facility that follows current Good Manufacturing Practices (cGMP).
