Sakuya
Nutrition for conception, pregnancy and the year after. First release: Sakuya Matcha, a complete prenatal you froth into milk.
Hera Biotech builds nutrition, tools and research for the XX body across the whole span of a life. Our first product is a prenatal. Founded in Brooklyn in 2026.

Our work runs in strands. Each strand is named for a deity, carries its own palette, and holds products, tools and research for one part of the XX body's life.
Nutrition for conception, pregnancy and the year after. First release: Sakuya Matcha, a complete prenatal you froth into milk.
Products and tools for XX men. Opens with a free tracker, then clinical products built around life on testosterone.
Studies on how XX bodies absorb and use nutrients, starting with iron, folate and the foods that block them.
Hera was queen of Olympus: goddess of marriage, of birth, of every stage of a woman's life, and a fierce protector of what was hers. She is usually shown with a pomegranate, the old sign of fertility and abundance. We took the name because that is the standard: sovereignty over your own biology, and nothing less than the best for it.
XX Biosciences is science built for bodies with two X chromosomes. That means women, and it also means XX men and anyone else whose physiology runs on XX biology. Thelytech is our word for the field: from the Greek thēlys, female, in the old sense of the generative body. Technology made for it, rather than adapted to it.
For most of modern medicine, the XX body was studied by studying men and scaling down. The result is dosing that was never tested on us, supplements that cannot be absorbed, whole stages of life that get no real research, and products that talk down to the people who buy them. Half of humanity is not a niche. So we run the trials nobody ran, and we publish the proof: third-party test results for every lot, and the design of every study we run, so you never have to take our word for it.
We study the XX body on its own terms. No stage is minor. Every seed counts: many small, exacting things add up to a life. Our first product is a prenatal because that is where the founder, a designer in Brooklyn, found the gap first. The strands that follow reach the rest.
