Sleep & Energy
Deeper sleep and clearer days, all in one sachet. A daily supplement formulated for the way a woman's body changes over time.
The 3 reasons your energy holds
Three ingredients. Nothing extra.
Magnesium is one of the first minerals depleted by stress, caffeine, and hormonal shifts. Most women fall short of the daily requirement, and the gap shows up as restless nights and tight muscles.
200mg of magnesium bisglycinate, the chelated form built for absorption. It supports the nervous system without the digestive trade-off that comes with magnesium oxide.
Form matters more than dose. Bisglycinate is bound to glycine, which is why it absorbs cleanly and does not sit in the gut like cheaper oxide forms.
Creatine is not only for athletes. It fuels the ATP system that every cell relies on, including the brain, and stores decline with age and with lower dietary intake.
5g of creatine monohydrate, the clinically studied dose. It supports cellular energy, muscle maintenance, and cognitive performance, particularly during periods of short sleep.
Creatine monohydrate is the most researched form available. The brain runs on the same energy system as muscle, which is why creatine helps with memory, mental processing speed and mood.
L-theanine is an amino acid found in green tea. It promotes alpha brain wave activity, the state the brain settles into when it is calm and alert at the same time. Thinking stays clear. The edge of anxiety comes off.
100mg of L-theanine promotes relaxation without sedation. No grogginess the next morning, and no dependency.
L-theanine does two things most ingredients cannot do at once. It sharpens focus without the anxiety, and it quiets the mental noise that makes falling asleep harder than it should be.
Energy and sleep aren't things you push through. They're the foundation of everything else.
Two halves of one system
A better night.
A steadier day.
Your cells run on ATP. Creatine rebuilds it fast, but the enzyme that does the rebuilding only fires when magnesium is there to switch it on. No magnesium, no usable energy. One half of the formula prepares the body to rest. The other refills what the day drained.
Settling down, staying down
Magnesium calms the nervous system and keeps cortisol in check. L-theanine settles the mind without knocking you out.
A better night, but rest alone doesn't refill what was already spent.
Refilling what ran out
Creatine rebuilds ATP, the fuel every cell runs on. But the reaction depends on magnesium to work at all.
Refilled reserves, but without the night half they drain again by morning.
Magnesium makes creatine usable.
Creatine replenishes what gets spent.
Each ingredient works on its own. Together they cover the full cycle: the quality of your sleep, the ease of getting there, and the energy you carry into the next day.
What to expect with consistent use
One sachet a night. Here is the order things tend to change, based on what the research shows for each active.
L-theanine works on the first dose. Most people notice the mind settling faster at bedtime rather than circling.
Creatine stores begin to saturate. Early signs are steadier energy through the afternoon and less of the 3pm drop.
Magnesium levels start to rebuild. This is where deeper sleep and less muscle tension tend to show up.
Creatine stores are full. You may notice sharper memory and quicker mental processing, most of all after a short night. Magnesium levels have rebuilt by now, supporting faster, deeper sleep.
Paired with resistance training, creatine supports lean muscle and strength. Sleep quality is now steady rather than swinging week to week, and your energy holds throughout the day. Most people describe this stage as feeling more like themselves.
This is the long game. There is no secret here beyond consistency. One small habit, repeated nightly, is what compounds into feeling good for years and not just weeks.
What we put in.
What we leave out.
Every choice in this formula is deliberate. Here is exactly what you are putting in your body, and what we refuse to.
You should know exactly what you're taking. Now you do.
Get my energy backChosen for
the evidence,
not the trend.
We didn't pick these three ingredients because they sound good on a label. We picked them because the research on each one is extensive, and because they work on the same underlying system: your body's energy and recovery.
Magnesium is one of the most studied minerals for sleep, and most of us don't get enough.
Magnesium is a cofactor in hundreds of processes in the body, including the ones that regulate your nervous system and cortisol. A 2021 systematic review and meta-analysis of randomized controlled trials found that oral magnesium supplementation reduced the time it took older adults to fall asleep by roughly 17 minutes compared to placebo. Research has also linked magnesium supplementation to lower nighttime cortisol and improved sleep efficiency. The bisglycinate form we use is chelated with glycine for high absorption and is gentle on the stomach.
Mah & Pitre, BMC Complementary Medicine and Therapies, 2021. Abbasi et al., Journal of Research in Medical Sciences, 2012.Creatine isn't just for muscle. Your brain runs on the same energy system.
Creatine helps regenerate ATP, the primary energy currency your brain relies on. A 2024 systematic review and meta-analysis of sixteen randomized controlled trials concluded that creatine monohydrate supplementation had a beneficial effect on memory, with the strongest evidence appearing when the brain is under metabolic stress, such as during sleep deprivation or mental fatigue. Recent trials show a single dose can measurably reduce the cognitive decline that comes with a poor night's sleep. We use 5g of pure creatine monohydrate, the form used in the research.
Xu et al., Frontiers in Nutrition, 2024. Gordji-Nejad et al., Scientific Reports, 2024.L-Theanine is the reason you can feel calm and alert at the same time.
L-Theanine is an amino acid found naturally in tea. EEG studies have repeatedly shown it increases alpha brain wave activity, the brain state associated with relaxed, focused attention. In placebo-controlled trials it has been shown to raise alpha power and lower salivary cortisol during a stressful task, supporting a state of calm alertness rather than sedation. It is what lets Somnii settle your nervous system without dulling your mind.

The depletion nobody talks about
Chronic stress, poor sleep, and hormonal shifts quietly deplete the nutrients that run your energy, focus, and mood. That feeling of being 'off' isn't in your head. It's in your cells. Somnii was formulated to close that gap and give back what daily life takes out.
Energy (without the crash)
Most energy drinks just borrow energy from your afternoon and make you pay for it with a 3:00 PM crash. We use Creatine Monohydrate to support your brain's cellular energy (ATP).
The Result: Steady, reliable focus that lasts through your day.
Stress regulation
Your nervous system takes on more with every passing year. We use Magnesium Bisglycinate, the most bioavailable form of magnesium and the one your body can actually absorb, to help regulate cortisol. So when the day comes at you hard, you can respond from a place of calm, not depletion.
Cognitive clarity
That foggy, scattered feeling is often just a lack of the right cellular fuel. By supporting your brain's ATP reserves and oxygen uptake, Somnii helps you think clearly, finish the sentence, and stay present in the moments that actually matter.
Designed for women
Most supplements are formulated for the 'average person' - which historically has meant men. But women's physiology is different: different stress patterns, different hormonal shifts, different recovery needs. Somnii was designed specifically for you.
Everything you
want to know
before you start.
The best version of you is the one you build from here.
One daily habit at a time.
30 sachets. One nightly ritual. The kind of recovery that shows up as patience, clarity, and the energy to actually be present.
