Sound familiar?
Your body is not failing you.
It is asking for more.
The shifts you are noticing in your 30s and 40s are real, measurable, and addressable. They are not signs of decline. They are signals worth paying attention to.
Sleep that no longer restores
You fall asleep fine. Then wake at 2am, mind already running. Or you sleep a full eight hours and wake up tired. One nutrient's depletion can disrupt an entire night.
Cognitive fog
The word that will not come. The thought that slips. The feeling that you are operating at 80% when you know you have more. This is a creatine gap, not a you problem.
Energy that does not match your ambition
You have more to do, more you want to build, more you want to experience. Your drive is fully intact. Your cellular energy has not kept up. This deficit is fixable.
Recovery that takes longer
Workouts that used to feel easy now linger. The body that bounced back quickly needs more now. Creatine supports muscle recovery and cellular energy production at the source.
Stress that sits differently
Not overwhelmed. Just not quite buffered. The cortisol peaks that used to resolve quickly are staying a little longer. Magnesium and L-theanine directly regulate the pathways that change this.
A body you want to invest in
You are paying attention now. You understand that the decisions you make at 35 compound. This is the right window to build from.
"The women who feel incredible at 45 started paying attention at 35. The window is not closing, quite the contrary, but it's time to act now."
Real women. Real results.
They started paying attention too.
★★★★★
"Honestly a 10/10, I'd recommend this product to everyone I know lol. Tastes amazing and mixes smooth, not gritty at all. Real lemon ginger flavor, monk fruit so no sugar. My stomach's been happy since I started, the magnesium is the gentle kind so no laxative nonsense. One sachet a day, totally worth it, glad I found it."
★★★★★
"If you've been forcing down gross powder creatine or horse pills, prepare to be pleasantly surprised. Somnii is a little sachet you mix in cold or warm water and it tastes like a lemon ginger drink. And it works, I've noticed creatine really helps my energy and my brain fog, and I recover better from workouts. Been on it a couple weeks and I just feel sharper and more like myself."
★★★★★
"So happy with it, my hot flashes have calmed down a TON and my mood is way up, the magnesium and theanine really help. Sleeping better and everything just feels more balanced. One sachet a day, gonna keep taking it for sure."
The science
Three ingredients.
All clinical dose.
Every ingredient has a reason. Every dosage is clinical. No fillers. No shortcuts. Built specifically for what a woman's body needs in her 30s and 40s.
200mg
Magnesium Bisglycinate
Sleep & stress
The form that actually absorbs. Regulates your nervous system, lowers cortisol, and supports deep sleep quality. Approximately half of all women are deficient (most without knowing it). This is the single most impactful evening supplement you are likely not taking at the right dose.
5g
Creatine Monohydrate
Brain & energy
The most researched supplement in existence and the one women are most underusing. Your brain and muscles run on creatine. Women have lower baseline levels than men, meaning the gains from supplementation are more significant. Sharper thinking. Stronger recovery. Real cellular energy.
100mg
L-Theanine
Calm focus
Calm without sedation. Found naturally in green tea, L-theanine promotes alpha brain wave activity: the state of focused, relaxed alertness. It quiets the noise without dimming the sharpness. The clean evening wind-down that does not leave you groggy in the morning.
What the experts say
The experts are paying attention.
These are not Somnii's claims. These are independent doctors and researchers talking about the ingredients themselves.
SS
"The number one supplement for women is creatine. It doesn't matter what age - it's really important. Women have lower baseline creatine levels than men, which means the supplementation gap is larger and the benefits are more pronounced."
Dr. Stacy Sims, PhD
Exercise Physiologist & Nutrition Scientist, Author of ROAR and Next Level
ON CREATINE FOR WOMEN
MH
Dr. Mary Claire Haver, MD
OB-GYN, Women's Health Specialist, Author of The New Perimenopause
"Creatine has incredible benefits for women. Recent studies have highlighted its cognitive and mood-boosting benefits - sharper memory, reduced mental fatigue, and a more positive outlook."

Dr. Jolene Brighten, ND, MSCP
Naturopathic Endocrinologist, Women's Health Practitioner
"Magnesium, particularly in the highly absorbable bisglycinate form, supports nervous system regulation, sleep quality, and hormone balance in women. Deficiency is far more common than most women realise."
ON MAGNESIUM BISGLYCINATE
MS
Dr. Melinda Sothern
Professor Emeritus, LSU Health Sciences
"In females especially, creatine improved memory significantly and attention as well. Numerous studies show that creatine supplementation improves health in women - and the benefits are more pronounced than in men."
ON CREATINE FOR WOMEN
A 2024 systematic review and meta-analysis of 16 randomised controlled trials found creatine supplementation delivered significantly greater cognitive benefits in women than in men, across memory, attention, and processing speed.
Frontiers in Nutrition, 2024. DOI: 10.3389/fnut.2024.1424972
All exercise and nutrition research has historically been conducted on men
Women are not small men. For decades, supplement dosing, clinical trials, and nutrition science defaulted to male physiology. Somnii is built around what the research actually says about women's biology, not adjusted-down versions of men's results.
By the numbers
The research is clear.
Independent studies on the specific ingredients in Somnii, in women.
CREATINE: BRAIN & COGNITION
16.4%
increase in frontal brain creatine levels in women after supplementation, versus 0.9% in the placebo group.
Higher frontal brain creatine is directly linked to sharper memory, faster reaction time, and reduced cognitive fatigue. The science connects the daily 5g dose to measurable change inside the brain itself.
CONCRET-MENOPA Randomized Controlled Trial, Journal of the American Nutrition Association, 2025
CREATINE: SLEEP RESILIENCE
18.2%
improvement in cognitive processing speed in women after creatine supplementation following a disrupted night's sleep.
When sleep is imperfect, which it often is, creatine protects the brain. Logic, language, and reaction time all held significantly better in women who supplemented versus those who did not.
Gordji-Nejad et al., Nutrients, MDPI, April 2026 (peer-reviewed)
MAGNESIUM: SLEEP QUALITY
17 min
less time to fall asleep after magnesium supplementation, plus 16 additional minutes of total sleep per night versus placebo.
Magnesium supports GABA activity and nervous system regulation - the pathways that govern both sleep onset and depth. Better sleep onset means more deep recovery, compounding over weeks.
2021 meta-analysis of oral magnesium supplementation for insomnia, cited by Elektra Health
MAGNESIUM: STRESS & CORTISOL
50%
of women are estimated to be magnesium deficient - most without any awareness that the gap exists.
Low magnesium is directly linked to elevated cortisol, disrupted sleep, and reduced stress resilience. Magnesium regulates the HPA axis - your body's core stress response system. The dose matters. Bisglycinate absorbs where oxide does not.
NIH Office of Dietary Supplements / Dr. Sarah Bonza MD, MPH, Healthline
L-THEANINE: SLEEP
9 of 13
clinical trials reported significant improvements in sleep quality from L-theanine supplementation at 200mg or more per day.
Falling asleep faster, fewer night wakings, better overall sleep quality - without sedation or morning grogginess. Clean wind-down that does not compromise the next day.
Cotter et al., Nutritional Neuroscience systematic review, 2026. DOI: 10.1080/1028415X.2025.2556925
L-THEANINE: CALM FOCUS
4 wks
for L-theanine to significantly reduce anxiety scores, improve mood, and improve sleep quality index in a randomised controlled trial.
L-theanine crosses the blood-brain barrier and increases alpha wave activity, which is the same neural state associated with calm alertness and meditation. The effect at 200mg is measurable, not theoretical.
Hidese et al., Nutrients, 2019
One sachet. Every night.
The last thing you do
each day should be
for you.
Mix one sachet into 6-10oz of cold or warm water. Lemon ginger - clean, not sweet, not medicinal. The magnesium and L-theanine work together to wind your nervous system down. The creatine starts building in your system overnight, so your brain and body have what they need before morning.
Most women notice better sleep quality within the first week. Cognitive clarity and steadier energy follow. The ritual itself matters as much as the science. One deliberate moment each evening that belongs entirely to you.
How it works
Simple enough to actually stick to.
1
Mix with water
Pour one Somnii sachet into 6-10oz of cold or warm water. Stir. Lemon ginger - clean, light, nothing synthetic. Sweetened with monk fruit only.
2
Make it your ritual
Take it in the evening - the same time, the same quiet moment. The magnesium and L-theanine work together to lower cortisol and ease your nervous system down without sedation.
3
Feel the compounding
Better sleep within the first week. Sharper cognition and steadier energy as creatine and magnesium reach effective levels. Give it 30 days. The shift is real and it builds.
Questions
The honest answers.
What if it doesn't work for me? ↓
Then you pay nothing. Try Somnii for 30 days, and if you do not feel a difference, we refund you in full. No questions, no hoops. Investing in your health should not carry financial risk.
How easy is it to cancel my subscription? ↓
Sign into your account, go to Subscriptions, and cancel directly from there. No phone call, no email chain, no hold music. You can also pause or skip an order instead if you just need a break.
Is Somnii only for women over 40? ↓
No. Somnii is built for women who are paying attention to their health, whether that starts at 32 or 45. The ingredients address nutrient gaps that are relevant to any woman in her 30s and beyond: magnesium deficiency, lower baseline creatine levels, and the cortisol load of a full life. The earlier you build the foundation, the more it compounds.
I already take supplements. Will this replace them or add to them? ↓
Somnii is designed as a consolidation. If you are already taking magnesium, creatine, or L-theanine separately, Somnii combines all three in the right forms and clinical doses in a single daily sachet. Many women find it replaces two or three separate products they were already buying.
How long until I feel a difference? ↓
Most women notice sleep quality improving within 2-3 weeks of consistent use. Cognitive changes like sharper recall, steadier energy, and less afternoon fog tend to follow over the following weeks as creatine and magnesium build to effective levels. Everyone is different, which is why the 30-day guarantee is there.
What does it taste like? ↓
Lemon ginger. Clean and light. Not sweet, not medicinal. Works in cold or warm water. No artificial flavours, no maltodextrin. Sweetened with monk fruit only. The kind of drink you want to make at the end of the day, not one you push through.
How long does shipping take? ↓
Orders ship within 1-2 business days and arrive within 3-5 business days across the US. Shipping is free on every order.
The foundation you build
now is the one you
live on later.
The women who feel exceptional at 45 made deliberate choices at 35. One clean evening ritual. Three clinical-dose ingredients. The compounding starts tonight.
