about this product.

Clair is a wrist-worn wellness wearable developed by women's health startup Clair Health, founded by Stanford graduates Jenny Duan and Abhinav Agarwal. It is designed to be the first device of its kind to offer continuous hormone monitoring for women in a non-invasive format.

Rather than requiring blood draws, urine tests, or finger-prick samples, Clair works through physiological inference — using an array of 10 biosensors to read signals from the body and generate real-time estimates of hormone patterns, including oestrogen and progesterone. The sensors monitor a range of physiological data points: skin temperature, heart rate, heart rate variability (HRV), respiratory rate, electrodermal activity, and sleep data. Onboard AI interprets these signals across more than 500 biomarkers to produce hormone insights.

For women navigating training load, cycle-based periodisation, or simply wanting a clearer picture of their hormonal health across the month, that kind of continuous visibility — delivered passively, without clinical appointments — represents a meaningful shift in what self-monitoring can look like day to day.

Beyond hormone tracking, Clair functions as a full-stack wellness wearable, capturing sleep quality, recovery, daily activity, and performance metrics alongside hormonal data. Everything is surfaced through an accompanying app, turning hormonal self-knowledge into a routine, accessible practice rather than a clinical undertaking.

Clair is expected to be available from November 2026. It is designed specifically for women, with the aim of making hormonal health monitoring as straightforward as wearing a watch.

The first adrenal support that made a quick difference.

4 days ago

Gentle on a sensitive stomach, and I feel like myself again. I had tried two other glandulars before this and neither sat right.

MRVerified Buyer

Steadier mornings within a fortnight.

1 week ago

I was sceptical about glandulars, but my mid-afternoon crash has genuinely eased. One capsule with breakfast and I forget about it.

ALVerified Buyer

Subtle, but real.

2 weeks ago

Not a stimulant, which is exactly what I wanted. It took about ten days, then I realised I wasn’t dreading the afternoon any more.

SKVerified Buyer

My clinician recommended it.

3 weeks ago

Bought after a blood panel flagged a flat cortisol curve. Easy to take, no jitters, and the sourcing is refreshingly transparent.

TPVerified Buyer

Recovery feels faster.

1 month ago

Training hard through a stressful stretch and this has helped me bounce back between sessions. Already on my second bottle.

DVVerified Buyer

Does what it says.

1 month ago

No frills, one ingredient, a sensible dose. I appreciate that it is designed to be used for a season rather than forever.
