Sleep & Energy Supplement

She did not lose herself.
She got depleted.
There is a difference
Growing and sustaining a human is one of the most demanding things your body can do. It depletes two nutrients most women do not supplement. Creatine: what your brain runs on. Magnesium: what your body needs to actually sleep.

You Are Not Alone In This
The depletion has a shape.
So does the way out.
You are stretched across two (or three) worlds and the system is genuinely hard. These are not personal failings. But if this is you, then there is something you can do about it.
The Double Shift
You wake up already tired. Not because you went to bed late. Because your brain started running the whole day before the alarm went off. Work, home, kids, logistics. By 9pm you have nothing left.
Invisible Invisibility
The world forgot you were a person before you were a mother. People ask your kids how they're doing. They ask you what the kids are doing. You used to have a name. You still do.
The Ambition That Won't Quit
You stepped back from your career deliberately, but you didn't stop being ambitious. You're building something after the kids are in bed. The laptop opens at 9pm. You just don't have the energy to sustain it.
The Fog That Won't Lift
Words that won't come. Thoughts that slip. The feeling that you are operating at 80% when you know you have more. Cognitive fog is not about mindset. It is about recovery. The good news? It is fixable.
The Moment You Laugh Again
You caught yourself laughing. Really laughing. Not at a screen at 10pm. A real laugh. And you realized it had been a while. That is the moment. That is when you know you are coming back to yourself.
The Independence You Miss
The guilt around spending money that is not technically yours. The hesitation before answering 'what do you do.' The feeling that investing in yourself is indulgent when really it is the most practical thing you can do. This season is a pause, not an ending.
"I lost my autonomy and that's been the hardest part for me. All the things that made me feel the most like myself were out of reach."
Real mothers. Real results.
The ones who took the energy back.
★★★★★
"The L-theanine is the ingredient I didn't know I needed. As a mom, my brain is always racing, wired but exhausted at the same time. This gives me a calm, clear focus without the jittery feeling I get from coffee, and it helps me actually switch off at night. I'm steadier through the day and far less snappy with the kids. The magnesium and theanine combination has been the real standout for me."
★★★★★
"As someone who reads every label carefully, this is the first supplement I've genuinely trusted. There's no maltodextrin, no aspartame and no sucralose, just monk fruit, so zero sugar. And there are no unnecessary fillers; it's simply the creatine, magnesium and theanine, and nothing else. As a mom, I don't want to be putting junk in my body every day, so that matters a great deal to me. It tastes lovely too, like a light lemon and ginger drink."
★★★★★
"Def buy Somnii. Had one sachet before bed and my legs relaxed right up, slept like an 'adult pre-baby' all night, the magnesium and l-theanine is great for that. And the couple times I had a question they got back to me fast."
The Science
Three ingredients.
All clinical dose.
Every ingredient has been chosen for what depleted mothers actually need. Better sleep. Cognitive clarity. The energy to be present in both worlds. No fillers. No shortcuts.
200mg
Magnesium Bisglycinate
Sleep & Stress
The form that actually absorbs. Regulates your nervous system, lowers cortisol, and supports deep sleep. About half of all mothers are deficient and don't know it. This is the single most important evening supplement you're likely not taking at the right dose.
5g
Creatine Monohydrate
Brain & Energy
Your brain and muscles run on creatine. Women have lower baseline levels than men, which means the gains from supplementation are more significant. Sharper thinking. Steadier energy. Real cellular fuel for the work happening in your head and body.
100mg
L-Theanine
Calm Focus
Calm without sedation. L-theanine promotes alpha brain wave activity: the state of focused, relaxed alertness. It quiets the noise without dimming the sharpness. The evening wind-down that doesn't leave you groggy when your kid wakes up at 6am.
The Experts Agree
The experts back up what you already know.
These are not Somnii's claims. These are independent doctors and researchers talking about the ingredients themselves, and what they do for women's bodies.

"The number one supplement for women is creatine. Women have lower baseline creatine levels than men, which means the supplementation gap is larger and the benefits are more pronounced."

"Magnesium, particularly in the highly absorbable bisglycinate form, supports nervous system regulation, sleep quality, and hormone balance in women."

"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."

"Many of my patients have benefited from adding L-theanine to their routine to help with stress, anxiety, and mental focus. Hormonal changes during perimenopause and menopause make women more prone to anxiety, and L-theanine directly supports that."
ON L-THEANINE
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.

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 exact fog that depletion creates.
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 broken - which it often is with young children - creatine protects the brain. Logic, language, and reaction time all held significantly better in women who supplemented.
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 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: DEFICIENCY
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. Pregnancy and breastfeeding deplete it further. The dose and form both matter - 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 - the same neural state associated with calm alertness. The effect at 200mg is measurable, not theoretical.
Hidese et al., Nutrients, 2019
One sachet. Every evening.
The last thing you do
should belong
entirely to you.
Mix one sachet into 6-10oz of cold or warm water. Lemon ginger. Clean, not sweet, not medicinal. The magnesium and L-theanine begin winding your nervous system down. The creatine builds overnight so your brain has what it needs before morning.
Most women notice better sleep within the first week. Cognitive clarity follows. But it is the ritual itself that might matter most. One deliberate moment each evening that is entirely yours. Before the mental load picks up again.
How It Works
Simple enough to actually stick.
1
Pour one sachet
Mix into 6-10oz of cold or warm water. Lemon ginger. No synthetic flavors. Sweetened with monk fruit only. Takes 90 seconds.
2
Make it your moment
Same time each evening. The magnesium and L-theanine work together to lower cortisol and ease your nervous system down without sedation.
3
Feel the shift
Better sleep within the first week. Sharper thinking and steadier energy as creatine builds. Give it 30 days. The compound effect is real.
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. The investment in your health should never 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 just for moms? ↓
Somnii is made for women moving through big transitions, new motherhood, the years of running on empty, the slow work of feeling like yourself again. Whatever is depleting you, the support your body needs is the same.
Can I take this if I'm breastfeeding? ↓
All three ingredients in Somnii are safe during breastfeeding and have been studied in lactating women. That said, consult with your OB-GYN or midwife if you have specific concerns. Many women use Somnii during this phase specifically because the depletion is most acute.
How long until I feel better? ↓
Most women notice better sleep quality within 2-3 weeks of consistent use. The cognitive shift - sharper thinking, steadier energy, less afternoon fog - tends to follow over the following weeks as the nutrients 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 flavors, no maltodextrin. Sweetened with monk fruit only. The kind of drink you actually want to make at the end of the day.
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.
You didn't lose yourself.
You lost the energy
to access yourself.
Those are different problems. This one is fixable. One clinical-dose evening ritual. The energy to be present in both worlds. The clarity to find your way back to yourself. It starts tonight.
