Four changes you'll feel in the first 4–8 weeks*
A whole night, not in pieces
A calm mind at bedtime
Still legs, relaxed body
Energy that's truly yours

Unlike ordinary magnesium, ROMERO breaks the cortisol loop that keeps you awake at 3am
Running low on magnesium does more than drain your energy. It pushes cortisol up, that cortisol burns through the magnesium you have left, and the loop wakes you at 3am wired and exhausted.
Ends the 3am cycle
Magnesium is the one mineral that signals your nervous system to stand down. With enough of it, cortisol falls, your mind stops racing and your sleep gets deeper as well as longer.
Feel Like Yourself Again.
Once your gut absorbs nutrients the way it should, everything changes: energy comes back, bloating settles, brain fog clears and you recognise the woman in the mirror again.
Feel Better. Every Day.
Proven benefits. Backed by research.
You deserve more than empty promises. ROMERO uses the exact form of magnesium that clinical research keeps pointing to.
Deep, unbroken sleepFall asleep faster and stay asleep all night.
ROMERO uses the form that truly reaches your nervous system and quiets the signals keeping your brain wired at night. Most people fall asleep faster within the first week, and by weeks 2–3 the 3am wake-ups shrink or disappear. You sleep through the night because your body finally has what it needs to rest, with nothing drugging you.
A calm nervous systemSoftens stress and quiets racing thoughts.
Exhausted all day, then wide awake the second your head touches the pillow, replaying every conversation: that wired-but-tired state is a nervous system stuck in overdrive. Magnesium is the mineral that signals it to slow down, helping your brain produce GABA to switch off racing thoughts and lowering cortisol, the stress hormone that keeps you on edge.
Goodbye, leg crampsStops nighttime cramps and settles jumpy legs.
Cramps start fading within the first week and are gone by week 2. If you've been loading up on potassium, sipping pickle juice or stretching for hours to fix them, the real culprit is nearly always magnesium your body can't use, and ROMERO fixes exactly that.
Wake up clear, never groggyRested, with zero drugged-out fog.
Here is where ROMERO parts ways with sleep aids. Melatonin leaves most people groggy and sleeping pills cloud your head for hours, while ROMERO simply restores what your body was missing. You fall asleep naturally, sleep deeper and wake up as yourself, with a clear head, steady energy and zero hangover.

Why experts point to this form of magnesium
The form your body can truly absorb, with the clinical research to back it.

One easy nightly habit
Two gummies before bed make up the entire routine: nothing to cycle, zero complicated timing, and not a single powder or app to manage.
- 2 gummies, 1–2 hours before bed
- Enjoy them at bedtime or with an evening snack
- Gentle enough for every single night
- Zero grogginess: magnesium isn't a sedative

The cleanest label you'll find
Per 2-gummy serving:
- 400mg magnesium bisglycinate, the only form absorbing close to 90%
- Sugar-free
- Plant-based pectin base (vegan)
What's not inside:
- Magnesium oxide
- Proprietary blends
- Stearates, fillers or flow agents
- Artificial colors or sweeteners
- Gelatin, gluten or GMOs
Third-party lab tested. Made in a GMP-certified, FDA-registered lab.

How it works in 3 steps
Step 1: It gets absorbed. Bound to glycine, bisglycinate is carried across your gut wall, so you take in around 90% of it versus about 4% from oxide.
Step 2: Cortisol falls. Magnesium signals your nervous system to stop firing stress alarms, cortisol comes down and the wired-but-tired feeling fades.
Step 3: Your brain makes GABA. Your brain needs magnesium to produce GABA, the neurotransmitter that switches off racing thoughts and lets you drift off, giving you deeper sleep, calmer mornings and an end to 3am wake-ups.
