Sleep & Energy
Dietary supplement for deep, restorative sleep and steady all-day energy. One nightly ritual, formulated for the way a woman's body changes over time.
Energy and sleep aren't things
you push through.
They're the foundation.
Somnii Sleep & Energy is a daily supplement for the sleep that actually restores you and the energy that lasts past 3pm. Three ingredients, at clinical doses, in one nightly ritual.
Three ingredients. Nothing extra.
The most bioavailable form of magnesium. Quiets the cortisol loop that keeps you wired at night, and supports the deep, restorative sleep your body needs to actually recover, without grogginess the next morning.

Most women feel a difference in sleep quality within the first one to two weeks. Cognitive benefits from creatine build over two to four weeks of consistent use. Not a quick fix, a daily deposit.

Chosen 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.
