Pouring a Somnii sachet into a glass of water

First, what it is

One sachet, three actives

A lemon ginger drink taken before bed, holding three actives at researched doses. Each one covers a different part of the night, and of the day after.

200mg
Magnesium bisglycinate

The mineral behind winding down. Relaxes muscles and nerves, and takes part in the stress response.

5g
Creatine monohydrate

Rebuilds ATP, the fuel every cell spends. In the formula for the brain rather than the gym.

100mg
L-theanine

An amino acid from green tea. Supports a calm state without causing drowsiness.

No melatonin, no added sugar, no fillers, no nasties.

Night one
Two of the three act immediately

What is working from the first sachet

MagnesiumAbsorbed the same night it is taken.
L-theanineCrosses into the brain within about an hour.
CreatineStarts accumulating. Nothing to feel yet.
01

Magnesium and L-theanine act on night one

Magnesium and L-theanine do not need to build up. Magnesium is absorbed the same night it is taken, and L-theanine crosses into the brain within about an hour, which is why the sachet is taken 30 to 45 minutes before bed.

Anything noticed in the first few nights comes from those two. Creatine is in the sachet from night one as well, but it is accumulating rather than acting.

02

The wind-down comes before the sleep does

Magnesium regulates the calcium that makes a muscle contract, so muscles release rather than hold. L-theanine supports a calm state without causing drowsiness.

That combination acts on the state a body is in before sleep rather than on sleep itself. It is a smaller thing than most sleep products promise, and it is the part that arrives first.

Weeks one to two
Nights compound, days lag behind

Two different clocks running at once

Every nightMagnesium and L-theanine act again from scratch.
Across the two weeksCreatine stores are still filling.
The gapThe night has changed before the day has.
03

The nights change before the days do

The evening actives reset every night. They do the same job on night twelve as on night one, which means whatever they contribute is available immediately and does not grow.

Creatine is the opposite. It does nothing on a single night and everything over several weeks. So the first fortnight tends to feel uneven: the nights have moved and the days have not caught up.

Weeks three to four
Stores fill, and the day changes

Why creatine takes the time it takes

The mechanismCreatine is stored, then drawn on as ATP is spent.
The rate5g daily fills stores over three to four weeks.
The tissueMuscle and brain both draw on the same store.
04

Creatine has to be stored before it can be used

Creatine is not used at the moment it is swallowed. It is held in tissue and drawn on when ATP is spent, so the amount available depends on how full those stores are.

At 5g daily that takes around three to four weeks. It is not a slow-acting ingredient so much as a stored one, and there is no way to hurry it that does not involve taking far more at once.

05

Taking it nightly is what makes it work

Taking it only after a poor night gets the evening actives and never gets the creatine, because stores that are drawn down between doses never fill.

Nothing here is a rescue remedy. The formula is built around daily intake, and the part most people are waiting for is the part that depends on it.

All three
Two on one process, one outside it

Where each active acts

Creatine Rebuilds ATP after it is spent

Magnesium Makes ATP usable in the first place

The same energy process

L-theanine Settling at the point of falling asleep

Leave one out and the process is incomplete at that point.

06

Why all three are in one sachet

Creatine rebuilds ATP after it is spent. Magnesium is what makes ATP usable, so the two act on the same process at different points and each is limited by the other. L-theanine works somewhere else entirely, on how settled a person feels at the point of falling asleep.

200mg magnesium bisglycinate, 5g creatine monohydrate, 100mg L-theanine. One sachet stirred into water, 30 to 45 minutes before bed. Thirty to a box, one for each night.

What a single box covers

Nights 1 to 14Magnesium and L-theanine, working from the first sachet.
Nights 15 to 30Creatine stores reaching full.
Day 30Everything in the formula is doing what it does.
If notFull refund, no questions asked.
07

Give it the full four weeks, then judge it

A box is thirty sachets, which is thirty nights, which is about the length of time the slowest part of the formula needs. Stopping at week two means judging it on two of the three actives.

Four weeks is also the honest test. Anyone can tell whether a drink is worth making again by then, and whether the mornings are any different. That is a better basis for a decision than anything written on this page.

If the answer turns out to be no, the guarantee covers exactly that window.

The formula

Delicious, not just tolerable

Real lemon and ginger, no added sugar, dissolves clear. A drink to look forward to, not one to get through.

Why these three?

Magnesium bisglycinate. Helps muscles and nerves relax, and makes ATP usable. Bonded to glycine so it is absorbed well.

Creatine monohydrate. Rebuilds ATP after it has been spent, in the brain as well as in muscle.

L-theanine. Supports a calm state at the point of falling asleep, without causing drowsiness the next morning.

All three. Magnesium and creatine act on the same energy process at two different points. L-theanine covers what that process does not reach.

Ingredients

Magnesium bisglycinate 200mg elemental, creatine monohydrate 5g, L-theanine 100mg from green tea, natural lemon and ginger flavor.

30 sachets per box, 7.6g per sachet. No melatonin, no added sugar, no artificial colors, no fillers or bulking agents, no proprietary blends.

Science & certifications

Third-party testing. Every batch is checked by an independent lab against the label, plus heavy metals and bacteria. Eurofins, July 2026: magnesium 236mg, L-theanine 103mg, creatine 5.68g. Each one at or above what the box says.

Certifications. FDA registered, GMP certified facility.

Directions

One sachet stirred into water, cold or warm, 30 to 45 minutes before bed. Daily. 30 sachets per box.

Consult a physician before use, particularly during pregnancy or while taking prescription medication. Magnesium can interact with some medications, including certain antibiotics.

What to expect

Week 1 to 2. The sleep side. Magnesium and L-theanine work from the first night.

Week 3 to 4. Creatine takes a few weeks to build up in muscle and brain, so the daytime difference comes later.

Which is why most people choose three boxes.

"I just feel sharper"

If you've been forcing down gross powder creatine or horse pills, prepare to be pleasantly surprised. i've notice creatine really helps my energy and my brain fog. Been on it a couple weeks and I just feel sharper and more like myself.

"Wake up genuinely rested"

What sold me is that there's no melatonin in it. I used to take melatonin gummies and I'd wake up groggy and foggy, almost like a hangover. I fall asleep more easily but wake up genuinely rested rather than zombied out.

"Peace of mind daily"

as a mom I really dont mess around with quality. this is third party tested, GMP, and they even test for heavy metals, which honestly most brands dont bother with. it gives me peace of mind taking it daily, and it works.

"Honestly a 10/10"

Tastes amazing and mixes smooth, not gritty at all. Real lemon honey 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.

"Not sweet, which I like"

Took a bit of time to arrive, but I like the flavor. I guess it's quite natual so it doesn't taste sweet at all. If you like really sweet stuff then better try another brand

Questions

The honest answers

How long before I notice anything?

Magnesium and L-theanine act from the first night. Creatine takes around three to four weeks of daily intake before stores fill, so the daytime part arrives later than the evening part.

How much anyone notices depends on where they start. Individual results vary, and some people notice very little.

Can I speed the creatine part up?

Loading protocols exist, and they involve taking considerably more per day for the first week. This formula is built around a steady 5g daily instead, which reaches the same place a little later and is easier on the stomach.

What happens if I miss a night?

One missed night is not a reset. Creatine stores draw down slowly, so an occasional gap mostly just pushes the timeline out. Regular gaps are different, because stores never fill in the first place.

What will it not do?

It is a dietary supplement, not a treatment. It does not diagnose or treat a sleep disorder, and anyone who suspects one should speak to a doctor rather than start here.

It also does not replace the basics. A dark cool room, a consistent wake time and a phone left in another room remain the highest-value changes available for sleep, and nothing in a sachet substitutes for them.

It is not a sedative either. Nothing in it is designed to knock anyone out.

Why do results vary so much between people?

Starting points differ. Someone whose magnesium intake is already below recommended levels has more room to move than someone whose intake is fine. Creatine stores start lower in women than in men, and lower again on a diet with little red meat.

Four weeks describes how the ingredients behave, not how anyone will feel. Individual results vary, and some people notice very little.

Who is Somnii for?

Women in the years when sleep is least reliable and the demands are highest. That looks different depending on where someone is: broken nights with small children, hormonal change through perimenopause and menopause, or the point where holding onto muscle and bone takes more work than it used to.

It is a dietary supplement, not a treatment for a diagnosed sleep disorder. Anyone who suspects one should speak to a doctor.

Will the creatine make me bulky or bloated?

Creatine is in this formula for the brain rather than for size. It draws a small amount of water into muscle cells, which is not the same as holding water under the skin, and it does not build muscle on its own. Visible muscle comes from training and eating for it.

The 5g here is the amount used in most of the research, taken daily rather than loaded.

Why is there no melatonin in it?

Melatonin is a hormone that signals when sleep should begin, so it acts before sleep starts. This formula works on staying asleep and on the energy available the next day.

There is also a difference between a nutrient, which the body takes in from outside, and a hormone, which the body already makes for itself. There is nothing here to wean off.

Can I take it in the morning instead of at night?

Creatine does not need a particular time of day, so that part works whenever it is taken. Magnesium and L-theanine are there for the evening, and that is where most of their value sits.

What does it taste like?

Real lemon and ginger, sweetened with monk fruit. Light rather than sweet, and not medicinal. It works in cold or warm water and dissolves to a clear pale yellow with nothing left at the bottom.

No added sugar, no artificial color, no filler.

Will it upset my stomach?

The form of magnesium is the usual culprit. Poorly absorbed forms stay in the digestive tract and hold water there. Bisglycinate is bonded to glycine, an amino acid, and is absorbed along amino acid pathways instead, which is why it is the form suited to taking every night.

Is it safe with medication, or during pregnancy or breastfeeding?

Consult a physician before use, particularly during pregnancy, while breastfeeding, or while taking prescription medication. Magnesium can interact with some medications, including certain antibiotics.

This is a dietary supplement. These statements have not been evaluated by the Food and Drug Administration, and it is not intended to diagnose, treat, cure or prevent any disease.

Is it third-party tested?

Every batch is sent to an independent lab and checked against the label, along with heavy metals and bacteria. Eurofins tested a production batch in July 2026 and measured magnesium at 236mg, L-theanine at 103mg and creatine at 5.68g, each at or above what the box says.

Made in an FDA registered, GMP certified facility.

How long does shipping take?

Orders ship within 1 to 2 business days and arrive within 3 to 5 business days across the US. Shipping is free on every order.

What if it is not for me?

Email sos@feelsomnii.com within 30 days and we will process a full refund. No questions asked.

How do I pause or cancel a subscription?

Sign into your account, open Subscriptions, and skip, pause or cancel from there. No phone call and no email chain.

Thirty nights is one box, and about one month.

Which is roughly how long the creatine takes. If it is not for you by the end of it, email sos@feelsomnii.com within 30 days and we'll process your refund. No questions asked.
