Key ingredients

Per serving (2 gummies, 30 servings):

  • 400mg magnesium bisglycinate (chelated for high absorption)
  • Sugar-free (stevia)
  • Pectin base (not gelatin — vegan friendly)

No magnesium oxide. No stearates. No proprietary blends. No artificial colors. No fillers that dilute the dose.

 

Third-party tested. GMP certified, FDA registered laboratory.

How it works

SPNutrition Bisglycinate is bound to glycine, which shuttles it through the gut wall. Absorption jumps to around 90%.

 

Once it's in your body, magnesium does four things your nervous system has been begging for:

  1. It calms the stress loop — magnesium shuts down excess cortisol, the thing waking you at 3am
  2. It relaxes smooth muscle — no more cramps, no more restless legs, no more tight shoulders
  3. It helps your brain make GABA — the neurotransmitter that turns off racing thoughts
  4. It restores the minerals you lose to caffeine, alcohol, stress, and prescription meds

You don't feel magnesium "kick in" like a sleeping pill. You feel it over a week. Deeper sleep. Calmer mornings. Body that stops fighting itself.

 

Automatic Refills ship every 30 days. You can pause or cancel at any time from the user portal or by emailing us.

How long before I see results?

Most people feel something within the first weeks.

 

Week 1: Falling asleep is easier. Fewer middle-of-the-night wake-ups. Cramps start to fade.

 

Week 2-3: You start sleeping through the night. Mornings feel different — less anxious, less foggy. Energy stabilizes.

 

Week 4+: The full effect kicks in. Your nervous system has rebuilt its magnesium stores. Stress doesn't spike the way it used to. Sleep becomes reliable.
 

Magnesium is a restoration, not a sedative. It takes a bit of consistency as 76% of Americans are already magnesium-deficient.

What our customers are saying:

Four things you'll feel in the first 4 - 8 weeks*

Once your body has the form of magnesium it can actually absorb, this is what comes back.

A full night, not in pieces

You go to bed, you stay asleep, and the alarm is what wakes you. Seven - eight hours that actually rest you. Mornings where you open your eyes and feel like you slept.

A quiet mind at night

That moment your head hits the pillow and your thoughts just settle. Your nervous system loosens. The day lets go. You drift off the way you used to before any of this started.

Calm legs, calm body

Your legs feel still. The muscles let go. You stretch out in bed and your body actually relaxes into the mattress instead of fighting it. Most people feel this in the first week.

Energy that's actually yours

You wake up rested and the day has fuel. The 2pm window stays open. You catch yourself in the mirror and look like the version of yourself you remember.

Unlike regular magnesium, SPNutrition  breaks the cortisol loop that's keeping you up at 3am

Low magnesium doesn't just make you tired. It raises cortisol. High cortisol burns through your magnesium. And the cycle keeps you waking at 3am, wired and exhausted.

Breaks the 3am cycle

Magnesium is the only mineral that tells your nervous system to calm down. When your body has enough of it, cortisol drops, your brain stops racing, and sleep gets deeper — not just longer.

Feel Like Yourself Again.

When your gut absorbs nutrients properly again, everything shifts. Energy returns. The bloating calms. The brain fog lifts. You start recognising the woman in the mirror.

Proven benefits. Backed by science.

Your body deserves more than empty claims. SPNutrition uses the form of magnesium clinical research keeps pointing to.

Deep, uninterrupted sleep

Fall asleep faster. Stay asleep through the night.

SPNutrition uses the form that actually reaches your nervous system, where it calms the signals that keep your brain wired at night. Most people start falling asleep faster within the first week. By week 2-3, the 3am wake-ups get shorter or stop completely. You sleep through the night — not because you're drugged, but because your body finally has what it needs to rest.

Calm nervous system

Takes the edge off stress and racing thoughts.

That wired-but-tired feeling — exhausted all day, but the moment your head hits the pillow your brain starts replaying every conversation you had — that's your nervous system stuck in overdrive. Magnesium is the mineral that tells it to slow down. It helps your brain produce GABA, the neurotransmitter that turns off racing thoughts. It  lowers cortisol, the stress hormone that keeps you on edge.

No more leg cramps

Stops nighttime cramps and calms restless legs.

Most customers report cramps fading within the first week. By week 2, they're usually gone. If you've been dosing up on potassium, drinking pickle juice, or stretching for hours trying to fix this — the real issue is almost always magnesium your body can't use. SPNutrition fixes that.

Wake up clear, not groggy

Rested — not drugged, not foggy.

This is where SPNutrition is different from sleep aids. Melatonin leaves most people groggy. Sleeping pills leave you foggy for hours. SPNutrition doesn't knock you out — it restores what your body was missing. You fall asleep naturally, sleep deeper, and wake up feeling like yourself again. Clear head. Steady energy. No hangover.

Fall asleep faster. Stay asleep through the night.

See the difference in your nights

Most people feel a shift in the first week. By week 4, your body has refilled what it's been running on empty for years.

Real Stories, Real Results

Honest experiences from people who tried everything else first.

Magnesium plus

Ever since my husband died, over 10 years ago, I have not slept well. Constantly waking up at 2 or 3 am and unable to go back to sleep for hours. I have tried many different items over the years until I came across this wonderful product. This specialized magnesium in the form of gummy bears really work. Last night I took two at 9 p.m., went to bed and woke up at 6:30 a.m. I slept all night long. I woke up refreshed and rested. I will sing praises for this wonderful product. Thank you.

Been using this for a month and my legs don't cramp at night anymore

Sleep is deeper too like I dont wake up every 2 hrs now. Used to be I would fall asleep fine then bam 2am wide awake, mind racing, calculating how few hours I had left before the alarm. Some nights I'd get a charley horse so bad it would knock me off my feet and I'd be limping around at 3am trying to walk it out. Tried other magnesium before and honestly thought it just didn't work for me. The cheap stuff from the drugstore did nothing and tore up my stomach on top of it.

I didn't expect it to work because I've tried everything

I didn't expect it to work because I've tried sprays, drinks, pills. Ineffective. Melatonin made me feel drugged out the next day. So I went into this completely not expecting it to work. I was pleasantly surprised. I fell asleep easily, got up one time to pee and slept through the night. I woke up feeling refreshed and great.

Why experts recommend this form of magnesium

The form your body can actually absorb — backed by the science and the reviews.

  • Daily use

  • What’s Inside

  • Why It Works

One simple nightly habit

Two gummies before bed. That's the whole protocol. No cycling, no complicated timing, no powder to mix, no pill-of-the-day app to manage.

✔ 2 gummies, 1-2 hours before bed

✔ Take them at bedtime or with an evening snack

✔ Gentle enough to take every single night

✔ No grogginess — magnesium isn't a sedative

The cleanest label on the shelf

Per 2-gummy serving:

  • 400mg magnesium bisglycinate — the only form that absorbs near 90%
  • Sugar-free
  • Pectin base (plant-based, vegan

What's not in it:

  • No magnesium oxide
  • No proprietary blends
  • No stearates, fillers, or flow agents
  • No artificial colors or sweeteners
  • No gelatin, gluten, or GMOs

Third-party lab tested. GMP certified, FDA registered laboratory.

The 3-step mechanism

Step 1 — It actually absorbs. Bisglycinate is bound to glycine, which carries it through your gut wall. You absorb around 90% of it — compared to 4% with oxide.

 

Step 2 — It drops cortisol. Magnesium tells your nervous system to stop firing stress signals. Cortisol drops. The "wired but tired" feeling fades.

 

Step 3 — It helps your brain make GABA. GABA is the neurotransmitter that shuts off racing thoughts and lets you fall asleep. Magnesium is required for your brain to produce it.The result: deeper sleep, calmer mornings, no 3am wake-ups.

Risk-Free Trial

Try SPNutrition completely risk-free for 30/60 or 90 nights based on your supply. 
If you don't sleep better, feel calmer, or notice a real difference — we'll refund every penny. No questions.

FAQ

Most people have the same worries — they've tried magnesium before and it didn't work, they're scared of wasting money, or they're not sure if we are a legit company. Here are the answers.

I've already tried magnesium and it didn't do anything. Why would this be different? 

Because what you tried was almost certainly magnesium oxide — or a "glycinate" that was quietly buffered with oxide. Your body absorbs about 4% of oxide. Bisglycinate absorbs close to 90%. It's the same mineral, but one reaches your cells and one passes through you. If you've been disappointed by magnesium, it's not magnesium that failed. It was the form.

How long before I actually notice something?

Most people notice sleep changes in the first 3-7 nights — falling asleep faster, fewer wake-ups, leg cramps easing. The deeper stuff — the 3am wake-ups stopping, stress feeling calmer — usually kicks in between week 2 and week 4. Give it 30 nights. If nothing changed, we'll refund you.

Will this make me groggy in the morning?

No. Magnesium isn't a sedative — it's a nutrient your nervous system needs to produce calm. You won't feel drugged. You won't have a hangover. Most people say mornings actually feel clearer, not foggier, once they've been on it a week or two.

Is 400mg too much? I'm sensitive to supplements.

400mg per 2-gummy serving is within the standard daily range for magnesium bisglycinate. If you're new to magnesium or very sensitive, start with 1 gummy for the first few nights and see how you feel. Bisglycinate is the gentlest form on the stomach — it's the one recommended for people who can't tolerate other types.

Can I take this with other supplements or medications?

Magnesium pairs well with most supplements, including vitamin D3, K2, and B-complex. If you're on prescription medication — especially blood pressure meds, diuretics, or antibiotics — check with your doctor about timing. Magnesium can interfere with absorption of some drugs if taken at the same time.

Is this a real company? Is the product legit?

Yes. SPNutrition is a registered company. Our gummies are manufactured in a GMP certified, FDA registered laboratory and third-party lab tested for purity and potency. We only sell on this website — if you see SPNutrition on Amazon or eBay, it's a fake. Every bag ordered here is authentic and backed by our 30-day guarantee.

What if I miss a night?

Nothing bad happens. Magnesium builds up in your body over time. Missing one or two nights won't undo your progress. Just start again the next night.

What's the money-back guarantee?

If you don't feel a real difference within 30/60 or 90 days, email us and we'll refund every penny. No questions. You don't even have to return the product. One email — that's all it takes.
