Our Science
Formulated for her.
Built to be shown.
Most supplements ask you to take their word for it. We'd rather show our work — from women's physiology to the exact amounts on the label.
- Every dose on the label
- No proprietary blends
- Formulated for women
Why we do it differently
The supplement aisle has a trust problem
Different bottle, same blank label. What's actually in there, and how much?
Built on a male baseline
Historically, most research studies only included men. Products formulated based on this research don't account for women's unique needs.
Hidden behind "blends"
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.
No proof on the shelf
"Clean" and "science-backed" are easy to print and hard to verify. Without independent results, they're marketing, not evidence.
The Seya way
Pillar one
We formulate for women
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, and the body processes nutrients differently.
We want to disrupt the "Male-Default" approach to health. We research areas where women have been underserved and develop products specifically for women. From ingredients and dosages to product formats and flavors, everything we do is centered on women.

The Seya method
How a Seya formula gets made
Every formula moves through the same path before it earns a place in your morning.
01
Research
We start where the evidence is thinnest — women's bodies — and work through it alongside our scientific advisors before anything moves forward.
02
Formulate
We choose ingredients with a clear rationale, in bioavailable forms your body can actually absorb. Not just the cheapest version of a nutrient.
03
Manufacture
We make it in the format you'll actually take every day, held to the amounts we set. No proprietary blends, no fairy dusting.
04
Verify
Every amount is printed on the label, and we explain why each one is there. If we cannot show you the proof, we do not make the claim.
What's inside
The science in every gummy
At Seya, we're obsessed with making clean-ingredient, great-tasting gummies — and showing you exactly what's inside.
Resistant tapioca fiber
4,500 mg
Prebiotic soluble fiber
950 mg
Cellulose
200 mg
Carrageenan
Named, not hidden
The seaweed extract that sets the gummy.
Three fibers. 16% of your daily fiber, in three gummies.
Most brands print "pure" and leave the gelling agent off the story. We'd rather name ours — carrageenan lets us hold a higher pH, so the actives don't break down as fast on the shelf.
Pillar two
Quality you can trust
The usual gummy
- Amounts hidden inside a "proprietary blend"
- A trace of the hero ingredient, for the label
- Cheapest available nutrient forms
- No way to see what's really inside
The Seya way
- Every active listed with its exact amount
- Meaningful amounts, chosen with intent
- Bioavailable forms your body can use
- Every amount printed, nothing to guess
The short list
What we leave out
Just as important as what goes in. You won't find any of these in a Seya formula.
Straight answers
Science questions, answered
What does "formulated for women" mean in practice?
It means we design with a woman's physiology as the reference point. We choose ingredients, forms, and formats with women's metabolism and hormones in mind, rather than scaling down a formula built and tested on men.
Why do you avoid proprietary blends?
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.
Are Seya products "clinically proven"?
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.
A gummy is a processed food. Why make one?
Because it's the format people actually take every day, and a supplement you skip does nothing. But we're not going to pretend a gummy is a whole food. It's a gel, a carbohydrate, water and an acid, and ours uses carrageenan as the gelling agent. Carrageenan sits on a lot of "avoid" lists, so here's the real reason it's in there: it lets us run a higher pH, which means the active ingredients don't break down as fast on the shelf. We'd rather tell you that than print the word "pure" over it.
