WHOOP is adding specialized blood testing for women and improved hormone tracking to its fitness platform. The company announced a Women’s Health Specialized Blood Biomarker Panel that tests 11 female-specific markers, plus new features that predict menstrual cycle symptoms.
The move comes as women make up a growing share of WHOOP users – up 150% year-over-year. Female members also use WHOOP’s AI features 30% more than men, showing strong demand for personalized health insights that account for hormonal changes.
“We’re not just helping women track their cycles,” said Alex Vannoni, Head of Healthcare Product at WHOOP. “We’re helping them understand how their physiology evolves over time – and giving them tools to act on it.”
How does it work?
The Women’s Health Specialized Panel tests biomarkers that standard health tests often miss or misinterpret for women. The 11 markers include:
- Anti-Müllerian Hormone (AMH) for fertility assessment
- Progesterone and Prolactin for cycle regulation
- Thyroid markers (Free T3, Free T4, TPOAb)
- Nutrients like B12, Folate, and Magnesium
- Leptin for metabolism
- Phosphate for bone health
WHOOP combines these lab results with data from its wearable device to show how biomarkers connect to sleep quality, recovery, and exercise tolerance over time. The app creates personalized reference ranges based on where a woman is in her menstrual cycle.
The new Hormonal Symptom Insights feature builds a personalized model of each user’s cycle. Instead of just recording symptoms after they happen, it predicts when they might occur based on the person’s historical patterns and physiological data.
Why does it matter?
Women’s health has been historically under-researched, with most medical studies focusing on men. This creates gaps in understanding how hormones affect everything from sleep to exercise recovery.
WHOOP’s approach addresses several key problems:
- Standard lab ranges don’t account for menstrual cycle phases
- Most health apps treat symptoms as isolated events rather than part of hormonal patterns
- Women often lack tools to predict and prepare for cycle-related changes
“Women don’t experience their physiology in silos,” said Emily Capodillupo, Senior Vice President of Research at WHOOP. “Hormones influence sleep, sleep affects recovery, and recovery shapes training response.”
The company published a white paper detailing its research methodology, including how the system accounts for irregular cycles, perimenopause, and hormonal birth control.
The context
WHOOP joins a growing field of companies focusing on women’s health technology. The Boston-based company already offers menstrual cycle tracking and pregnancy insights, but the new features go deeper into the underlying biology.
The blood testing builds on WHOOP’s Advanced Labs program launched last year. Members can order tests through the app, with results integrated into their ongoing health data rather than treated as standalone snapshots.
WHOOP has raised over $400 million in funding and ships to 56 countries. The company says peer-reviewed research shows daily users exercise 90 more minutes per week and sleep two additional hours compared to before using the device.
The Women’s Health Specialized Panel launches in April, initially available only in the US. WHOOP works with medical advisors including Dr. Robin Berzin and Dr. Hazel Wallace, and recently partnered with menstrual health company Clue.
