SUMM started with a question nobody could answer.

What happens when you are mid-career, performing at your peak, and your body starts working differently? You Google it at midnight. You book a clinical appointment and get told it might be stress. You buy supplements from Boots that do nothing. You start wondering if you are the problem.

The gap that SUMM exists to close.

There are 13 million women in perimenopause in the UK. Most have no diagnosis. Most have never been told that the brain fog in their Monday morning meeting, the rage at nothing, the exhaustion that sleep does not fix, the joints that ache for no reason, are all connected to the same hormonal shift.

The information exists. It is buried in research papers and clinical guidelines. But nobody has built it into something a busy professional woman can actually use, in the time she actually has, in a way that gives her evidence she can take to her clinician.

So we built it.

SUMM is a perimenopause platform for professional women. Free tools that help you understand what is happening, track it over time, and take evidence to your clinical appointment.

The symptom checker tells you whether your pattern looks like perimenopause, thyroid, or burnout. The daily tracker measures sleep, energy, and cognitive clarity in 30 seconds and builds a 14-day baseline. The clinical report gives your doctor structured data instead of a verbal description from memory. The ingredient checker tells you whether your current supplements are actually working.

Everything is free. Everything is evidence-based. Nothing requires a diagnosis to use.

Who built this.

SUMM was founded by a service designer who spent years building digital platforms for NHS Digital and running clinical trials communications at AstraZeneca R&D. The SUMM Core formulation was developed by a Women's Health Registered Dietitian with NHS and private clinical experience in perimenopause nutrition.

We are not a wellness brand. We do not sell hope in a jar. We build tools that give professional women the information they need to make good decisions about their health.

What comes next.

SUMM Core is an evidence-based daily powder launching September 2026. Seven ingredients at clinical doses, formulated for the three things perimenopause disrupts most: muscle retention, energy metabolism, and cognitive function. It is being built alongside the tracker so that when it launches, every woman using SUMM already knows exactly what her body needs and why.

Start with the symptom check.

Free. No account needed. Your results become Day 1 of tracking.
