BOSTON, Mass. — WHOOP has announced a series of new health initiatives focused on women’s physiology, including the launch of a specialized blood biomarker panel designed to provide deeper insights into hormonal health and long-term wellness.
The new Women’s Health Specialized Blood Biomarker Panel expands the company’s WHOOP Advanced Labs offering and builds on the baseline panel introduced last year. The panel adds 11 clinically supported biomarkers intended to provide insights into areas that are often under-measured or misinterpreted in traditional women’s health testing.
The announcement also includes new predictive health features within the WHOOP app and the publication of a Menstrual Cycle White Paper detailing the research and modeling behind the company’s menstrual cycle tracking system.
WHOOP said the new initiatives reflect a broader effort to address longstanding gaps in women’s health research and data. According to the company, women represent a rapidly growing segment of its user base, with membership increasing by 150 percent year over year. The company also said female members interact with its AI-powered features about 30 percent more frequently than male members.
“Unlike solutions that focus on isolated conditions or single life stages, WHOOP delivers a connected health experience informed by one of the world’s largest datasets on women’s physiology,” said Alex Vannoni, Head of Healthcare Product at WHOOP. “We’re not just helping women track their cycles. We’re helping them understand how their physiology evolves over time – and giving them tools to act on it.”
The Women’s Health Specialized Panel, scheduled to launch next month, includes biomarkers associated with hormonal regulation, thyroid health, nutrient status, and metabolic resilience. The panel tests for Anti-Müllerian Hormone, progesterone, prolactin, thyroid peroxidase antibodies, free T4, free T3, leptin, vitamin B12, folate, magnesium, and phosphate.
WHOOP said the lab results will integrate with data collected from its wearable device and AI-driven modeling systems, allowing users to see how biomarker levels correlate with sleep, recovery, training strain, and stress patterns over time.
The company is also introducing a new feature called Hormonal Symptom Insights and Predictions, which expands its menstrual cycle tracking capabilities. The update allows users to receive personalized predictions based on physiological data and historical patterns, including projected cycle windows, variability trends, and expected symptom patterns.
Through integration with WHOOP Advanced Labs, the system can also adjust biomarker reference ranges depending on where a user is in their menstrual cycle, categorizing results as optimal, sufficient, or out of range based on individual physiology.
WHOOP also released a detailed white paper describing the scientific methodology behind its cycle modeling system. According to the company, continuous physiological monitoring allows prediction accuracy to improve over time while accounting for irregular cycles, perimenopause, and hormonal birth control.
“What makes this powerful isn’t any single data point – it’s how the system comes together,” said Emily Capodillupo, Senior Vice President of Research, Algorithms, and Data at WHOOP. “Women don’t experience their physiology in silos. Hormones influence sleep, sleep affects recovery, and recovery shapes training response. By modeling these interactions over time – across continuous biometrics, lab data, and behavior – we can deliver guidance that reflects the full system, not just a snapshot.”
WHOOP said the initiative is supported by its medical advisory board, which includes Dr. Robin Berzin and Dr. Hazel Wallace, and builds on a recent collaboration with menstrual and reproductive health platform Clue. The company said the new tools are part of its broader mission to improve long-term health outcomes through personalized physiological insights.
