Perimenopause, before it has a name

It starts sooner than anyone told you.

Perimenopause begins, on average, seven years before a woman's last period — often in her late thirties — and the first signs get called stress. Forecast is the four-product foundation for those years, and the app that shows you what's coming and what's working.

Recognition

Things that get called "just stress."

Falling estrogen and progesterone don't announce themselves. They show up as ordinary complaints, years apart, that no one connects. Most women hear "you're too young for that" at least once before anyone says the word.

Waking at 3am, wide awake, for no reason.

Progesterone is the first hormone to drop. It's also the calming one.

A cycle that got shorter, or heavier, or both.

Often the earliest measurable change — and the most likely to be waved off.

Anxiety that arrived without a story.

New-onset anxiety in the late thirties is a recognised early sign.

Rage at 4pm. Tears at 9.

Worsening PMS that stretches across more of the month.

A shoulder that froze, joints that ache.

Estrogen receptors sit in connective tissue. Fewer signals, stiffer joints.

Losing the word. Losing the thread.

"Brain fog" is the most common complaint and the least believed.

Part one · the products

Four things change when estrogen starts to fall: your nights, your frame, your weave, your core.

Not a hormone blend. Not a 27-ingredient "harmony" formula. One product for each, named for what it looks after — with the plain ingredient name right underneath, always.

Sleep & nervous system

Night

Magnesium glycinate

The gentle form — easy on the stomach, and glycine itself is calming. Taken before bed, it supports the deeper, unbroken sleep progesterone used to underwrite. The one you'll notice first.

Your evening magnesium

Skin, hair & joints

Weave

Collagen peptides

Skin collagen falls quickly once estrogen does. Hydrolyzed peptides are the form the body absorbs; half a scoop dissolves clear and tastes of nothing. Supports skin elasticity and joint comfort.

Grass fed · unflavoured

Muscle, bone & brain

Frame

Creatine monohydrate

The most-studied supplement there is, with growing evidence for women in midlife: supports muscle, bone and cognition as estrogen's protective effect fades. Five grams in your coffee. Not a bodybuilding product.

For the long view

Gut & the estrobolome

Core

Gut health

A set of gut bacteria — the estrobolome — helps regulate how much estrogen your body recycles. Prebiotic fibre, a probiotic strain, and digestive enzymes to support it.

Four actives, all named

Part two · the app

Every tracker tells you what happened. Forecast tells you what's coming.

Two taps a day. After two weeks it starts issuing a daily outlook built from your own history, finds the patterns that make your days better or worse, and lets you test whether anything you're taking is actually doing something. Forecast+ is $9.99 a month on its own — free with the Foundation.

Everything that's in it

The front of every label is the ingredient list.

Not the back. Not a "proprietary blend." If it's in the bottle, it's the first thing you read. Two of the four have exactly one.

Night · magnesium glycinate

Magnesium glycinate, vegetable capsule, rice flour, magnesium stearate, silicon dioxide.

Five things. All of them named.

Weave · collagen peptides

1

Bovine hide collagen peptides.

That is the entire ingredient list.

Frame · creatine monohydrate

1

Creatine monohydrate.

That is the entire ingredient list.

Core · gut health

Organic apple cider vinegar, inulin, L. acidophilus, DigeZyme® enzymes.

Four actives. The capsule ingredients are on the label too.

Why this, and not the usual

Most "menopause" products are built for a woman ten years further along.

The category

— Black cohosh, red clover, dong quai — herbs for hot flushes, aimed at women already deep in symptoms.

— Twenty-plus ingredients in a "proprietary blend" you can't see the doses of.

— You take it and hope. Nothing tells you whether it's working.

— Interactions with contraceptives, antidepressants and anticoagulants, rarely mentioned.

Forecast

— Built for the years before — the muscle, bone, sleep and gut changes that start first and matter most later.

— Every ingredient and every dose on the front.

— An app that shows you, in your own numbers, what's changed — and says so when nothing has.

— The herbal product exists as a separately screened add-on, with questions to answer first.

Questions

Is this hormone therapy?

No. Nothing in the Foundation is a hormone or acts like one. It's a nutritional foundation for the systems that change in the transition. If you want to talk about hormone therapy, that's a conversation with a clinician — the app's doctor report is built to help you have it.

I'm 37 and I feel fine. Is this for me?

That's exactly who it's for. Muscle, bone and collagen are easiest to keep and hardest to get back; the point of starting before you need it is that "need" arrives quietly.

Do I need the supplements to use the app?

No. The basic app is free and works whatever you take — our products, someone else's, HRT, or nothing. Forecast+, the full version, is $9.99 a month on its own and free for as long as you subscribe to the Foundation.

What happens to my data? And if I cancel?

What you log is never sold, never shared and never used for advertising. If you cancel the Foundation, your account moves to the free version (or you can keep Forecast+ for $9.99 a month), your history stays, and you can export or delete everything whenever you like.

How does the guarantee work?

Take the Foundation for 30 days and log your sleep in the app. If it hasn't improved, email us and we refund your first month — keep the products. On the 90-day box, that's the first month refunded plus a refund for anything you return unopened.

Can I take it with birth control or an antidepressant?

The four Foundation products have no known interactions with hormonal contraceptives or SSRIs. The Shift add-on is different — it's a botanical blend with real interactions, which is why it's screened separately. As always, tell your doctor what you take.

Who shouldn't take this?

If you're pregnant or nursing, have kidney disease, or are under a doctor's care for any condition, ask them first. Every label says the same.
