Most creatine research was conducted on male athletes — yet emerging studies confirm it's just as impactful for women, supporting muscle protein synthesis, cognitive function, and metabolic health across the hormonal cycle.
Why it's in Seya
Supports muscle synthesis at the female baseline. Enhances brain energy metabolism. 3g per serving — the clinically studied dose.
Why we started
For too long, women's health has been an afterthought. Legacy pharmaceutical research was built on a default male model — leaving women with products that ignore their unique metabolic, hormonal, and cognitive needs.
Despite controlling 80% of household healthcare spend, women receive only 6% of total healthcare investment. We are here to close that gap.
— Elliott & Andrew, co-founders
