The formulation rationale

Three things happen to your body in perimenopause that most supplements ignore entirely.

You start losing muscle faster than you think.

Declining oestrogen accelerates skeletal muscle loss, not just for athletes, for every woman who wants to stay strong, mobile, and metabolically healthy through midlife and beyond. Most perimenopause supplements don't touch this.

Your energy doesn't work the way it used to.

Fatigue in perimenopause isn't laziness. It's hormonal fluctuation, disrupted sleep, and micronutrient shortfalls compounding. Summ Core addresses the nutritional side of that equation, the part that's actually within reach.

Your brain feels different. That's real too.

Brain fog, word-finding difficulty, mood shifts. These have a nutritional dimension and Summ Core includes ingredients with EFSA-authorised claims for normal psychological function and nervous system support.

Why only 300

We're a small, independent company. We're not VC-backed. We're not trying to be everything to everyone.

We built Summ Pattern first, the symptom pattern check, daily tracking, the GP report generator, and the Supplement Label Checker, because we wanted to understand what women actually need before we put anything in a sachet.

The 300 founding members are the women who get that. Who want evidence, not marketing. Who are tired of being sold things that don't work by brands that don't understand their bodies.

If that's you, there's a spot with your name on it.

For now.

Formulated by a Women's Health Registered Dietitian with NHS and private clinical experience. Every ingredient backed by peer-reviewed research. Full ingredient list and doses published before launch, no surprises.

The EFSA-authorised health claims associated with the ingredients in this formulation apply to the correction of nutritional insufficiency and the support of normal physiological function. They should not be interpreted as implying the formulation will produce measurable symptomatic outcomes in women who are already meeting their nutritional requirements, or that it will address the hormonal and vasomotor aspects of the menopause transition.
