What you’re noticing

Sign 1 of 6 · Forgot why I came

You walk into a room and forget why you came.

You were sure a second ago. Now you’re standing in the kitchen, waiting for it to come back.

Why it happens: During the transition, estrogen falls, and everyday mental tasks can take more effort. Holding on to why you walked in is one of them.

Sign 2 of 6 · Word won’t come

The word you want is right there, and it won’t come.

Mid-sentence, mid-meeting, mid-story. You end up saying “the thing” and hoping they know what you mean.

Why it happens: Finding the right word is an everyday mental task too. When estrogen falls, it can start to take more effort than it used to.

What it does to your day

Sign 3 of 6 · Rereading lines

Reading the same line three times before it sinks in.

An email, a recipe, a page of your book. You get to the end and realize none of it went in.

Why it happens: When estrogen falls, everyday mental tasks can take more effort. Your reading didn’t get worse. The same page just costs more now.

Sign 4 of 6 · Notes everywhere

Sticky notes everywhere, just to keep up.

The fridge, the monitor, the back of your hand. If you don’t write it down, it’s gone.

Why it happens: When estrogen falls, holding things in mind can take more effort. So your notes started doing the remembering for you.

How it feels

Sign 5 of 6 · 3pm focus crash

By mid-afternoon, your focus is gone.

You start the day fine. By three o’clock you’re staring at your to-do list and nothing gets started.

Why it happens: When estrogen falls, everyday mental tasks demand more effort. Spend that extra effort all morning, and by 3pm there’s less left for focus.

Sign 6 of 6 · Feeling off

You’ve wondered if you’re losing your mind. You’re not.

You haven’t said it out loud. But after a week like this, you’ve thought it.

Why it happens: When estrogen falls, everyday mental tasks can take more effort. That’s a hormone shift, not you.

If two or more sounded like you, you don’t have six problems. You have one.

During the transition, estrogen falls, and everyday mental tasks can take more effort. One cause, one daily fix: two capsules of Peri/Meno Essentials.

Why brain fog starts in perimenopause.

  • Estrogen
  • Your brain’s estrogen receptors, which may rise
  1. Before 40
  2. Perimenopause
  3. Now
  1. Plenty of estrogen signal
  2. The signal drops
  3. Plant isoflavones offer a signal it can recognize

Estrogen normally docks with receptors throughout the brain. That signaling supports many everyday functions. During the transition, estrogen falls. But receptor density may increase and stay elevated for years. That gap can make everyday mental tasks demand more effort.

Your brain isn’t failing. More open receptors are meeting less of the signal they were built for. That one gap can make all six of these moments harder.

Here’s what happened when women took one daily formula for 3 months.

Why coffee, lists and focus pills haven’t cleared the fog.

  • More coffee✕ Buys you a few hours. Then the fog is back.
  • “Focus” pills✕ Made for anyone who wants an edge. Not made for the menopause shift.
  • Waiting it out✕ Everyone says it passes. Nobody says when.
  • More notes and lists✕ Help you work around the fog. They don’t touch the cause.

Questions before you start

Is this a brain supplement?

93% of women in our study reported improvement in brain fog by month 3.* It’s built for the whole menopause transition, so the same formula was studied across 14 measures, including hot flashes, night sweats and sleep.

Will it help my memory?

93% of women in our study reported improvement in brain fog, which the survey described as lapses in memory and feeling less sharp.* That was self-rated. We didn’t run memory tests.

When will I notice a difference?

86% of women in our study reported improvement in brain fog at month 1, and 93% by month 3.* For mental exhaustion, the share reporting improvement rose every month, from 76% to 93%. Plan on three bottles.

What’s in it?

A 400 mg blend per 2-capsule serving: red clover (providing 50 mg isoflavones), bergamot phytosome and olive fruit extract.

Does it contain hormones?

No. It contains botanical extracts, not estrogen or progesterone medication. Red clover supplies isoflavones with estrogen-like activity. Ask your clinician about suitability, particularly with hormone-sensitive conditions or hormone therapy.

I already take a multivitamin or a focus supplement. Can I keep taking them?

They do different jobs. A multivitamin or focus supplement is made for anyone. Peri/Meno Essentials is built for the menopause shift behind the fog. If you take other supplements or medication, show the labels to your doctor or pharmacist.

Pregnant, breastfeeding, or on HRT or medication?

Check with your healthcare professional before starting. It’s a dietary supplement, not a replacement for prescribed hormone therapy.

Is the 3-month plan a subscription?

Yes. £61.60 every 3 months. Skip or cancel from your account anytime. Prefer not to subscribe? The single bottle and the one-time 3-pack are right above.

Is it right for my age?

It’s made for perimenopause and menopause. The women in our study were 40 to 57.

Start clearing the fog tomorrow.

Coffee, lists and focus pills work around the fog. It showed up when your estrogen started falling. Peri/Meno Essentials is made for that shift: two capsules a day, three bottles to reach month 3. See a difference in 90 days, or your money back.

P.S. Every week you wait is another week of sticky notes and words that won’t come. Two capsules tomorrow is the easiest place to start.
