Tell Me About:

The same woman drained at her kitchen counter in the afternoon and wide awake in bed at night

Why you are tired all day and wired at night

Stress burns through magnesium faster than a normal diet replaces it. Low magnesium leaves your stress-response system more reactive, so the same pressure hits harder. Cortisol that is supposed to fall in the evening stays elevated, melatonin cannot rise on schedule, and you end up exhausted but wide awake at 11pm. Broken sleep pushes the next morning's cortisol higher still, and the loop tightens.

There is exactly one input in that loop you can change tonight, and it is the mineral your body is burning through. MG+ replaces it in the two forms your cells actually take up, with the cofactors that carry it inside and the botanicals that quiet a racing mind.

What people actually notice

  • Falling asleep faster, and staying asleep through the 3AM window
  • A calmer baseline under pressure instead of a short fuse
  • Steadier energy through the afternoon rather than a hard crash
  • Fewer night cramps and less restless-leg twitching
  • Feeling less puffy and tense as stress load comes down*

Most customers report better sleep inside the first two weeks. Stress and energy benefits build over 30 to 60 days of consistent daily use.

Three capsules, 30 to 60 minutes before bed

One serving is three capsules. Take them with a little water about half an hour before you want to be asleep. Magnesium works on a cumulative basis, so the single biggest predictor of results is taking it every night rather than only on bad nights.

If you are sensitive to supplements, start with two capsules for the first three nights and move to three. MG+ uses chelated forms rather than magnesium oxide, which is why it does not cause the stomach trouble most drugstore magnesium does.

300mg elemental magnesium plus the cofactors that use it

Two chelated magnesium forms, magnesium bisglycinate chelate and magnesium citrate, delivering 300mg of elemental magnesium per serving. No magnesium oxide anywhere in the formula.

Alongside it: 60mg vitamin B6, 900mcg methylated B12, 900mcg methyl folate, 45mg niacin and 9mg chelated zinc, the cofactors involved in getting magnesium into cells and keeping it there. Plus a 210mg botanical blend of cramp bark and passionflower for muscle relaxation and calm.

Dusk To Dawn

Feel What A Proper Magnesium Actually Does

Not a sedative. A mineral your body is short on, put back in a form it can use.

Woman turning off a bedside lamp
  • 9PM

    The tension starts letting go

    Magnesium bisglycinate is chelated with glycine, which is calming in its own right. Cramp bark and passionflower work on the physical side of winding down.

  • 11PM

    The racing mind goes quiet

    Magnesium supports normal regulation of the HPA axis, your stress-response system, so the day stops replaying the moment your head hits the pillow.

  • 3AM

    You stay asleep

    The wake-up window most people never get past. No cramp, no jolt, no lying there doing math on how many hours are left.

  • 7AM

    You wake up rested, not wrecked

    A night that actually restored something. This is where the loop starts running the other direction.

  • 3PM

    The crash does not come

    Magnesium is required for cellular energy production, and the B vitamins here are in their active methylated forms.

Published Research

300mg. The Same Daily Dose The Trial Used.

Most magnesium brands will not tell you how their dose compares to the research. Here is ours, straight.

PLoS ONE · 2018 · Randomized clinical trial · N=264

Adults with low magnesium taking 300mg daily cut their stress scores by more than 40% in eight weeks.

Researchers recruited 264 healthy adults who had both low serum magnesium and elevated stress on the DASS-42 scale. Participants were randomized to 300mg of magnesium daily, or 300mg of magnesium plus 30mg of vitamin B6, for eight weeks.

42–45%reduction in stress scores in both magnesium groups at week 8
24%greater improvement from adding B6, in the severe-stress subgroup only

Being straight with you about what this shows. Across the whole group, magnesium plus B6 was not significantly better than magnesium alone. The extra benefit from B6 showed up only in participants who started out severely stressed. The trial was single-blind and funded by the supplement's maker. What it does establish clearly is the dose: 300mg of daily elemental magnesium moved stress scores in real people, and 300mg is exactly what a serving of MG+ delivers.

Pouteau E, Kabir-Ahmadi M, Noah L, et al. Superiority of magnesium and vitamin B6 over magnesium alone on severe stress in healthy adults with low magnesemia: A randomized, single-blind clinical trial. PLoS One. 2018;13(12):e0208454. MG+ is not the product used in this trial.

The Mechanism

Your Magnesium Isn't The Problem. Your Cortisol Loop Is.

It is not one problem with three symptoms. It is one loop that feeds itself.

1

Stress spends your magnesium

Cortisol increases how much magnesium you lose through your kidneys. A demanding week literally drains the mineral.

2

Low magnesium makes you more reactive

Magnesium helps regulate the HPA axis. With less on board, the same pressure hits harder.

3

Cortisol stays high into the evening

Cortisol is supposed to fall at night so melatonin can rise. When it doesn't, you are exhausted but wide awake.

4

Broken sleep raises tomorrow's cortisol

You start the next day already behind, more reactive, and burning magnesium faster.

↺ And the loop starts again, a little worse each week

Cortisol through the day: a healthy rhythm falls from morning to night, while a stressed rhythm sags mid-day then climbs into the evening

Cortisol is supposed to fall as the day goes on. Under sustained stress the curve inverts, and the crossover lands right where you are trying to fall asleep. Illustrative, not measured data.

You don't need more willpower. You need magnesium back in your cells.

That is the one input in this loop you can actually change tonight.

Use Daily For Best Results

What's Actually In It, And Why

Six working parts, and one that is deliberately absent. Every dose printed on the label, not buried in a blend you cannot read.

Magnesium bisglycinate chelate

Part of 300mg elemental

Magnesium Bisglycinate Chelate

The most absorbable form of magnesium. Chelated with glycine, an amino acid that is calming on its own, which is why this form is the one associated with sleep rather than with the bathroom.

Magnesium citrate

Part of 300mg elemental

Magnesium Citrate

Highly bioavailable and easily dissolved. It works alongside the bisglycinate so the full 300mg dose actually gets absorbed instead of passing through.

Three methylated B vitamins in ceramic dishes

60mg B6 · 900mcg B12 · 900mcg folate

Methylated B Vitamins

B6 at 60mg is a clinical-grade cofactor dose, not a label decoration. B12 as methylcobalamin and folate as methylfolate are the active forms, so your body does not have to convert them before it can use them.

Chelated zinc granules on slate

9mg

Zinc Bisglycinate Chelate

Chelated zinc, not zinc oxide. Zinc and magnesium work the same shift in stress response and recovery, and the chelated form is the one that does not turn on an empty stomach.

Cramp bark and passionflower

210mg blend

Cramp Bark + Passionflower

Two centuries-old botanicals for muscle relaxation and natural calm. This is the part plain magnesium glycinate does not have, and it is what handles the 3AM cramp.

Magnesium oxide compared with chelated forms

What is not in it

Zero Magnesium Oxide

The cheap form that most of the aisle is built on, and the reason people say magnesium wrecked their stomach or did nothing. There is none of it in here. Every mineral in this formula is chelated.

Frequently Asked Questions

How is MG+ different from the magnesium at the drugstore?

Two things. First, the form: most cheap magnesium is magnesium oxide, which is poorly absorbed and is the reason drugstore magnesium sends people to the bathroom instead of to sleep. MG+ uses magnesium bisglycinate chelate and magnesium citrate, and no oxide at all.

Second, the cofactors. MG+ includes 60mg B6, methylated B12 and folate, chelated zinc, and a 210mg botanical blend of cramp bark and passionflower. Almost nothing else in the category ships the escort nutrients alongside the mineral.

How long until I feel a difference?

Most customers report calmer nights and better sleep inside the first 7 to 14 days. Stress, energy and recovery benefits build over 30 to 60 days of consistent daily use, because magnesium works by replacing a deficit rather than by sedating you.

Will it upset my stomach like other magnesium did?

That reaction is almost always magnesium oxide, which is not in this formula. Both magnesium forms here are chelated, and so is the zinc. If you are especially sensitive, start with two capsules for three nights and then move to the full three-capsule serving.

When and how do I take it?

Three capsules with water, 30 to 60 minutes before bed. One bottle is 90 capsules, which is a full 30-day supply. Consistency matters more than timing, so take it nightly rather than only on rough nights.

Will it knock me out or leave me groggy?

No. There is no melatonin and no sedative in this formula. It is a mineral and botanical supplement, not a sleep drug, so there is no morning fog to sleep off and nothing that forces you under. It is also non-habit-forming, so there is nothing to taper off if you stop.

Can I take it with my other supplements or medications?

Magnesium pairs well with most daily supplements, including vitamin D and calcium. Magnesium can interfere with the absorption of certain prescriptions, so if you take any medication regularly, run it past your doctor or pharmacist first. Same if you are pregnant, nursing, or have kidney issues.

“I tried magnesium from the store. All it did was upset my stomach. I almost gave up. I am glad I found Outback MG+ because it actually works. I use it before bed and sleep so much better. My fitbit sleep scores have gone from the mid 60s to the high 80s almost every night.”

How To Use It

Three Capsules. Every Night. That's It.

Step 1

Three capsules

One serving is three capsules. Ninety capsules per bottle, so one bottle is a full 30 nights.

Step 2

30 to 60 minutes before bed

With a glass of water. No food required. Chelated forms are gentle on an empty stomach.

Step 3

Every night, not just bad ones

Magnesium works cumulatively. Nightly consistency is the single biggest predictor of results.

About Us

Natural Relief, Made Properly

The Outback Series team

The Outback Series has shipped more than 1.6 million bottles of natural relief products to over 100,000 customers. We built our name on the Original Roll-On Oil, and we only add a product when we can make it meaningfully better than what is already on the shelf.

MG+ exists because the magnesium aisle is full of magnesium oxide with no cofactors, sold on a sleep promise it cannot keep. So we built the formula the other way around: the two forms your cells actually take up, the escort nutrients that get it inside them, and the botanicals that handle the physical side of winding down. Then we backed it with a full year to decide, and you never have to ship the bottle back.

I didn't expect such noticeable results, but Outback Magnesium+ really helps me unwind at the end of the day. My mind feels less busy at night, and I'm getting deeper, more restful sleep than I have in a long time.

I've struggled with falling asleep for years, but after trying Outback Magnesium+, I noticed a difference within a week. I feel calmer at night, and I'm actually staying asleep instead of waking up multiple times. It's become part of my nightly routine.
