Bovine Ovary Powder
Also known as: raw bovine ovary, glandular ovary extract, bovine glandular therapy, raw ovarian concentrate
Effective Dosage
No established dose
What the Science Says
Bovine ovary powder is a glandular supplement made from dried, ground cow ovaries. It is marketed based on the theory that consuming animal glandular tissue provides hormones or hormone precursors that may influence human hormonal activity — a concept sometimes called 'glandular therapy.' Proponents claim it may support estrogen-related functions such as breast tissue development or menopausal symptom relief, but there are zero published clinical trials supporting these claims, and the actual hormonal content and bioavailability of these products is largely unknown.
What It Doesn't Do
No clinical evidence it grows breast tissue in adults. No proven effect on menopause symptoms. Not a substitute for medically supervised hormone therapy. The idea that eating ovary tissue directly boosts your hormones is not supported by science. No evidence it balances hormones in any measurable way.

Absorption & Bioavailability
Unknown — digestive enzymes likely break down most proteins and hormones before absorption; actual hormonal content of commercial products is unverified and unregulated
Red Flags to Watch For
- Zero clinical trials exist — all claims are based on anecdote or outdated glandular therapy theory
- Unregulated hormone content: products may contain unpredictable levels of estrogens or other hormones, posing real health risks
- Potential contamination risk from animal-sourced glandular tissue including prions, pathogens, or pesticide residues
- Heavily marketed to transgender women and teens for breast development with no scientific backing — this is exploitative
- May interact with hormone-sensitive conditions like estrogen-receptor-positive cancers, endometriosis, or PCOS
- Over 1,000 registered supplement products exist despite no published clinical evidence — a major red flag for consumer exploitation
