THE IDEA
The perimenopause supplement market is full of products doing too much. Thirty ingredients, five bottles, a protocol you need a spreadsheet to follow. Summ is different. One daily sachet. A small number of ingredients, each chosen for a specific reason, each dosed properly.
01
Energy and fatigue
The tiredness sleep does not fix. Dosed to the research.
02
Muscle and strength
Muscle changes from your mid-30s. Ingredients studied in midlife women, at the right dose.
03
Cognitive clarity
Brain fog is biochemical, not personal. Nutrients that contribute to normal cognitive function.

HOW WE BUILD
Every ingredient in Summ has one job. It has to earn its place — the right form, the right dose, a reason that holds up. If it does not: it is not in the formula.
01 / 04
Earned, not assumed.
No ingredient gets in on the basis of trends or tradition. Each one has to justify its inclusion independently.
02 / 04
The right form matters.
Cheap forms absorb poorly. We always choose the form your body can actually use, even when it costs more.
03 / 04
Dosed to work.
Most supplements underdose. We dose to the evidence, not to the label.
04 / 04
Fewer is harder.
It is easy to add more. It takes conviction to keep the formula small and stand behind every choice in it.
"It did not exist. So I built it."
In my early 40s: brain fog, disrupted sleep, strength slipping. I had spent years building evidence-based systems at NHS Digital. I knew what good looked like — and the supplement market was not it.
