Most supplement research was run on men, then scaled down for women. We started with the female baseline instead.
Science-first. Woman-first.
Ingredient histories
A closer look at a few of the ingredients we are proud to print on the panel.
Most creatine research was run on male athletes, yet the emerging work confirms it matters just as much for women, supporting muscle, cognition and metabolic health across the cycle.
A large share of women fall short on daily magnesium. The glycinate form is highly bioavailable, which makes it a gentle choice for supporting sleep quality and everyday stress.
KSM-66 is one of the most studied ashwagandha extracts, with a deep bench of human trials behind it. It is used to support a calmer stress response without dulling your day.

Why we started
The formula we needed did not exist.
For too long, women's health has been an afterthought. Legacy research was built on a default male model, leaving women with products that ignore their metabolic, hormonal and cognitive needs.
Seya starts from the female baseline instead. Honest formulas, every ingredient on the label, made for the body actually taking them.
