The evidence base
The cognitive symptoms of menopause are not anecdotal. They are measurable, documented, and consistent across multiple studies and brain imaging research. These are the numbers that shaped the Solenne formula.
How widespread are cognitive symptoms in menopause?
Large-scale studies consistently show that 75% of women going through menopause experience cognitive symptoms of some kind; most commonly, word-finding difficulties, impaired short-term memory, reduced concentration, and slower processing speed. These are not isolated complaints. They represent the single most prevalent and least treated symptom in menopause transition.
of women going through menopause experience cognitive symptoms
Does it affect professional performance?
Yes. Research specifically examining the professional impact of menopause-related cognitive symptoms shows that 60% of affected women report their work performance is measurably impacted, including impaired performance in meetings, slower decision-making under pressure, difficulty with presentations, and reduced confidence in high-stakes professional interactions. This is the population Solenne was designed for.

What happens to acetylcholine during menopause?
Acetylcholine is the critical 'smart' neurotransmitter responsible for memory formation, information retrieval, and concentration. Research documents an up to 50% reduction in the activity of the enzymes that make Choline in the areas of the brain responsible for memory and decision making during menopausal transition. This happens because estrogen is key in controlling acetylcholine production. When estrogen declines, so does acetylcholine. It's not a global dulling of intelligence; it's just the physiological reality of the hormonal transition during menopause, but these pathways can be structurally supported!
reduction in the activity of the enzymes that make Choline in the areas of the brain responsible for memory and decision making.
How many women are affected globally?
An estimated 1.6 billion women worldwide will experience menopause. The cognitive dimension of this transition represents one of the largest and most systematically ignored public health issues in women's medicine. No supplement brand had addressed all of the underlying biological factors before Solenne.

“The menopausal brain is not broken. It is running on less energy. The result is not a worse brain; it is a tired brain with an energy deficit.”
The brain brownout
Not a blackout. Not a breakdown. A brownout: when the system is intact but running below capacity. This is Solenne's framework for understanding what menopause actually does to the brain, and it is grounded in peer-reviewed science.
What is the Brain Brownout?
The Brain Brownout is the term Solenne has coined to describe the measurable reduction in cognitive performance that accompanies the decline in estrogen during perimenopause and menopause. It is not a metaphor. It describes a specific neurobiological event: the reduction of energy production in the regions of the brain most responsible for the cognitive functions that define professional performance. The word brownout is chosen deliberately. Unlike a blackout, a brownout does not represent system failure; it represents a system running under capacity due to insufficient power. The brain is not broken. It is underpowered. That distinction matters enormously, both clinically and psychologically, for the women experiencing it.
What is the estrogen-glucose connection?
Estrogen is widely understood as a reproductive hormone. What is less widely communicated is its role as a key driver of energy production in the brain. Normal levels of Estrogen drive glucose into brain cells in several key ways, including the production of more ‘transporter’ proteins that can carry glucose across cell membranes into brain cells, as well as making brain tissue more sensitive to the hormone insulin, which allows cells to be more able to absorb those proteins carrying the glucose. When estrogen levels decline during the menopausal transition, fewer glucose carrier proteins are produced, and the cells become less sensitive to insulin. The consequence is a measurable reduction in energy production in the hippocampus and the prefrontal cortex, the two regions most responsible for memory formation, word retrieval, and executive decision-making. Special brain imaging studies designed to see how active different parts of your brain are have confirmed this reduction in energy production in menopausal women. This has given us direct evidence for the cause of the menopausal symptoms women are suffering from.
What is the FSH-Brain Connection?
Estrogen decline is only half the story. When estrogen drops, your brain begins overproducing Follicle-Stimulating Hormone (FSH) in a frantic attempt to stimulate the ovaries. For decades, scientists thought FSH only affected the reproductive cycle. However, the latest neuroscience reveals that when there is an FSH spike in perimenopause, it crosses into the memory and decision-making areas of the brain, causing damage. This research shows that high FSH levels are a key factor in the lower activity and dropped energy production seen in menopausal brain scan studies.
What exactly did the Brain scan studies show?
The studies have shown significant reductions in the activity of the parts of the brain known as the hippocampus and prefrontal cortex, during and after the menopausal transition. These areas are directly responsible for the cognitive symptoms most commonly reported: impaired memory, word loss, and reduced executive function. These findings have been repeated again and again in imaging studies over decades. Solenne is built specifically to address all of the factors affecting energy production in the brain and is the first ever supplement to do so.
Is this permanent? Will it get worse?
No. This is a critically important distinction. The cognitive symptoms of menopause are caused by reduced energy production in specific brain regions, but the brain remains intact. In permanent, structural conditions, brain cells physically die and tissue is permanently lost.
Six pathways.
One formula.
No single ingredient addresses the full complexity of the brain brownout. Solenne targets six distinct biological mechanisms, each contributing to cognitive performance in the menopausal brain. Together they form a coordinated, comprehensive response to menopause, which so far has always been overlooked.

How Solenne Works
The six pathways
No single ingredient addresses the full complexity of the brain brownout. Solenne targets six distinct biological mechanisms, each contributing to cognitive performance in the menopausal brain. Together, they form a coordinated, comprehensive response to menopause, which so far has always been overlooked.
Pathway 01: The Hormone Reset
Normal Estrogen levels signal to your brain that everything in the world is good. Estrogen is also the master key that unlocks your brain's energy supply, pulling glucose into your cells to keep your mind sharp.
However, during menopause when estrogen levels drop, two things happen at once. First, the brain's fuel delivery abruptly stalls, starving cells of energy. Second, unable to find the estrogen it expects, the brain signals danger. It fires a hormonal SOS signal to your ovaries in the form of FSH (Follicle-Stimulating Hormone), demanding they release an egg to produce more estrogen.
But because the ovaries can't respond like they used to, the brain never gets that estrogen payoff. So, it keeps hitting the alarm. FSH levels skyrocket to 10 times higher than normal. This isn't just a reproductive issue—it's a neurological crisis. While your brain cells are starved of fuel, that sudden, violent surge of FSH hits receptors right in your thermostat (the hypothalamus) and your mood center (the amygdala). The result? Brain fog and memory problems from the energy crash, colliding with hot flashes, night sweats, and that sudden, unprovoked "fight-or-flight" anxiety. It can feel like a panic attack because, biologically, your master controls are panicking.
Most remedies just try to top up your estrogen. But to actually fix the chaos, you have to cut the wires on the alarm. By pairing Genistein to mimic estrogen and safely restore that vital cellular fuel line, with Ashwagandha to calm the nervous system, you stop the FSH spike at the source. You aren't just masking symptoms; you're telling the brain it's safe to stand down.
Pathway 02: Fuel the Brain
Once hormonal pathways stabilize, your brain needs the raw power to rebuild. Riboflavin and Biotin act as Solenne's master generator, directly supporting the cellular mitochondria to get energy production firing consistently and restore daytime stamina. Beyond pure energy, this combination delivers an essential defense against hormonal head tension and sensory sensitivity:
- Mitochondrial Fueling: Riboflavin ensures brain tissues have the constant energy required to prevent crashes and acute mental strain.
- Vascular Resilience: It actively supports steady, healthy blood flow to the head, leaving you clear, comfortable, and pressure-free.
Instead of just fighting off fatigue, this pathway builds structural resilience, giving your brain the metabolic strength to stay clear, cool, and collected.
Pathway 03: Sharp Memory & Recall
Acetylcholine is the critical messenger at the center of everything the menopausal brain struggles with: forming thoughts, maintaining focus, and finding words under pressure. When estrogen levels shift during this transition, the activity of the natural enzymes that manufacture this "smart" messenger can drop by up to 50% in your memory and decision-making centers. Your internal assembly line for sharp focus slows to a crawl.
Citicoline targets this breakdown directly. By supplying the highly bioavailable raw materials your brain needs, it fuels acetylcholine production while simultaneously reinforcing the vital structural layers of your cell membranes. It doesn't just patch a symptom; it helps rebuild the baseline processing power of your mind.
Pathway 04:Calm Focus & Cortisol Control
The standard industry response to menopause is to look at hormones in total isolation. But your brain doesn't work that way. The transition triggers a dual assault on your focus: a sharp rise in the stress hormone cortisol, and a massive spike in Follicle-Stimulating Hormone (FSH), a pairing that drives localized brain fog and mental fatigue. No other supplement company targets both pathways simultaneously, because they miss the latest research showing how the sudden spike in FSH can affect brain function. Solenne changes this framework in 2 ways:
- Ashwagandha KSM-66® (300 mg): Breaks the chronic stress loop and balances your system's response to cortisol. It actively buffers your memory centers against the disruptive FSH surge, providing calm protection without daytime drowsiness or emotional flattening.
- L-Theanine: Promotes a state of calm, alert focus. It creates a smooth mental runway for Citicoline to kick-start executive functioning, providing immediate clarity on day one while the heavier ingredients build up over time.
Instead of just masking the load, you are reducing the physical impact of stress while restoring a sharp, focused mental state.
Pathway 05: Neuroplasticity & Brain Resilience
Lion's Mane + Zinc Bisglycinate + Saffron
True longevity demands mental adaptability, your brain’s capacity to maintain and create new connections between cells. This trifecta of Lion's Mane, Zinc, and Saffron acts like a catalyst for your brain, ensuring you remain fast, fluid, and sharp. High-level mental agility relies entirely on neuroplasticity—the brain's capacity to constantly re-wire and form new connections. Solenne fuels this adaptable network from three distinct angles:
- Lion’s Mane (100% Fruiting Body, 30% Extract): Actively supports your brain’s natural growth factor (NGF) pathways, helping keep your internal communication lines clear and healthy.
- Zinc Bisglycinate: Provides an easily absorbed mineral that your brain cells need to talk to each other, helping new memories stick.
- Saffron Extract: Gently supports neurotransmitter balance to protect emotional resilience and mood stability, keeping the neural network calm and receptive to new growth.
This is not a brain managing decline. This is a brain continuing to develop.
Pathway 06: Mood, Sleep, and Cognition
Deep sleep is the ultimate cognitive restorer, it is when the brain locks in memory and recharges the mental energy used during the day. Because the menopausal transition disrupts the neurotransmitters that control your sleep cycle, it directly compromises daytime focus.
Solenne addresses this breakdown at the root with MoodReal®, a patented Saffron Extract standardized to 2% safranals and 4–6% crocins. Backed by over 10 clinical trials, this specific extract is scientifically proven to optimize your natural sleep and balance the neural pathways that give us emotional resilience.
No other botanical matches saffron’s clinical track record for lifting daytime mood, reducing perceived stress, and restoring deep, restorative sleep.

WHAT’S INSIDE
The Ingredients
Every ingredient in Solenne is included at a clinically relevant dose, for a documented reason, targeting a specific mechanism. There are no fillers, no proprietary blends, and no ingredients included because they look good on a label. Serving size: 3 capsules. What follows is the full clinical rationale for each.
Riboflavin (Vitamin B2) - 400 mg
Role: Mitochondrial Energy & Cognitive Stamina
Timeline: Enhancements to cellular energy begin in month one, with optimal mental stamina and deep resilience peaking by month three of consistent daily use.
The Science: Most multi-vitamins include a tiny 1.5 mg pinch of Riboflavin just to tick a box. Solenne delivers a robust, clinically targeted 400 mg serving. This specific high-potency threshold is recognized in neurological research for its unique ability to maximize mitochondrial energy production and support healthy, steady blood flow within the brain.
The Impact: Menopausal shifts cause massive drains on brain energy. Reductions in brain cell energy directly compromise mental performance, triggering brain fog, sudden head tension, and sensory sensitivity to bright lights or loud noises. Providing 400 mg ensures your neural pathways have the deep energy reserves required to stay clear, focused, and resilient under pressure.
Ashwagandha KSM-66 - 300 mg
(standardized to 5% withanolides)
Role: Cortisol Regulation & Stress Resilience
The Science: Solenne uses clinically backed KSM-66®, standardized to 5% active withanolides. Within four to eight weeks, multiple clinical trials confirm it significantly reduces cortisol, the chronically elevated stress hormone that impairs memory and drives mental fatigue.
The Impact: Beyond stress, KSM-66® works progressively over eight to twelve weeks to stabilize the specific hormonal stress responses that spike during menopause. Think of it as lowering the background noise of stree. By keeping cortisol in check, it protects your memory pathways and supports natural hormonal balance, working alongside genistein to preserve daytime focus and mental clarity.
Citicoline - 250 mg
Role: Acetylcholine Support & Brain Cell Structure
The Science: When estrogen plummets, the enzymes that build acetylcholine, your brain’s primary focus neurotransmitter, drop significantly in the command centers for decision-making. Solenne’s Citicoline bypasses these bottlenecked enzymes. Within five hours of your first dose, it crosses the blood-brain barrier to restock your brain's raw material supply line.
The Impact: By flooding the system with bioavailable choline building blocks, it helps your neural machinery produce acetylcholine efficiently. Think of it as restocking the cognitive fuel supply. This targeted baseline sharpens verbal recall and boosts daytime mental stamina.
Lion's Mane - 250 mg
(30% Polysaccharide Extract)
Role: New Connections & Nerve Growth Factor (NGF) Support
The Science: Most brands use unstandardized powder. Solenne uses a high-potency 30% polysaccharide extract. In the first four weeks, it supports baseline cellular energy and natural antioxidant defenses.
The Impact: By weeks eight to twelve, it acts as the formula's structural backbone, stimulating the growth proteins that build and maintain neural infrastructure. Think of it as building the mental machinery. While faster ingredients handle immediate focus, Lion's Mane drives the new connections required for long-term memory consolidation and cognitive resilience.
Genistein - 60 mg
Genistein - 60 mg (from Sophora japonica)
Role: Estrogen Receptor Support & Cognitive Signaling
The Science: Sourced from premium Sophora japonica rather than soy, Genistein is a targeted phytoestrogen. It is backed by clinical research for its unique ability to cross the blood-brain barrier and selectively bind to estrogen receptors in the brain's memory and decision-making centers.
The Impact: As natural estrogen levels shift during menopause, crucial brain signals slow down. Genistein steps in to activate these receptors, keeping the neural pathways firing. Think of it as maintaining the brain's communication network. For women navigating menopause, this targeted support preserves memory, sharpens attention, and offsets the cognitive effects of hormonal transition.
Saffron - 30 mg
(standardized to 2% Safranals · 4 - 6% Crocins)
Role: Mood Balance & Neurotransmitter Protection
The Science: Saffron works across three distinct timelines. Within hours, its active compounds cross the blood-brain barrier to ease daily tension. By weeks two, mood and emotional resilience strengthen noticeably. By week six, it delivers a steadier, brighter daily outlook.
The Impact: Cognitively, saffron protects acetylcholine from premature breakdown. Think of it as guarding your brain's cognitive fuel supply. The extract is batch-standardized to 2% Safranals to support mood-regulating brain chemistry, and 4% to 6% Crocins to support neural cellular health and antioxidant defenses
L-Theanine - 100 mg
Role: Calm Focus & Alpha Brainwave Support
The Science: At 100 mg, L-Theanine is optimized for daytime cognitive performance. Within the first hour, it eases daily stress and mental tension without causing drowsiness. It creates a calm, clear mental state, delivering immediate, tangible clarity on day one while the long-term ingredients build their full structural effects over weeks and months.
The Impact: Paired with Ashwagandha KSM-66®, it hits the stress pathway from two distinct angles. While Ashwagandha manages the physiological cortisol load over time, L-Theanine immediately sharpens the focused mental state that daily pressure suppresses. Think of it as clearing the immediate mental clutter so your brain can actually utilize its energy.
DIM (Diindolylmethane) - 100 mg
Role: Estrogen Metabolism & Cellular Balance
The Science: DIM is a naturally occurring compound found in cruciferous vegetables like broccoli. It supports healthy estrogen metabolism at the cellular level, promoting conversion toward less stimulatory pathways. It does not artificially raise or lower estrogen; it simply optimizes how your body metabolizes what is already present.
The Impact: Paired with Genistein, it manages the hormonal dimension of menopausal cognitive shifts from two directions. While Genistein safely targets the receptors your brain depends on, DIM ensures the body's baseline estrogen follows the cleanest, healthiest pathway. Think of it as upgrading the brain's internal filtration system. These metabolic shifts begin to take hold within four weeks of consistent use.
Biotin - 30 mcg Pathway:
Role: Energy Production; Neurological Support
The Science: Biotin is an essential B-vitamin that drives the deep metabolic processes responsible for supporting the structural integrity of your neural pathways, the biological infrastructure that enables rapid signal transmission between neurons.
The Impact: Working directly alongside Riboflavin in the cellular energy pathway, it ensures your brain's metabolism has the baseline support needed to operate at full capacity. Think of it as the ingredient that keeps the cognitive engine running smoothly, preserving the foundational wiring required for clear, reliable daily performance.
Zinc (as Zinc Bisglycinate) - 10 mg
Role: Synaptic Communication & Cognitive Resilience
The Science: The memory center of the brain contains one of the highest zinc concentrations in the body. Zinc actively regulates the communication between brain cells and the receptor activity central to learning and memory formation. Solenne uses premium Zinc Bisglycinate, a highly bioavailable form absorbed and utilized far more efficiently than standard zinc.
The Impact: By ensuring the brain receives a steady, reliable supply, it helps maintain the stable environment that long-term memory depends on. Think of it as tuning the brain's internal receivers. This targeted support preserves clear signal transmission, giving you cognitive resilience against daily mental fatigue.
"The menopausal brain is not broken. It is running on less energy. The result is not a worse brain; it is a tired brain with an energy deficit."
