500 mg of elemental magnesium per 2-capsule serving — 119% of the daily value — across five forms: Aquamin™ marine magnesium, glycinate, malate, citrate and oxide. Three inactive ingredients only: hypromellose, rice flour, silicon dioxide.

Nearly all magnesium on the shelf is a salt synthesised in a plant. Aquamin™ isn't — it's drawn from seawater off the Irish coast as magnesium hydroxide, and it comes carrying roughly 72 other trace minerals that were dissolved in the water with it: silicon, boron, selenium, zinc, iodine and more. You're getting the mineral profile of the ocean rather than one isolated compound.

A bottle shouting "1,000 mg" is usually quoting the weight of the compound, not the mineral. Elemental magnesium is what your body actually receives. We lead with 500 mg elemental because it's the one figure you can hold against any other bottle on the shelf.

All five deliver elemental magnesium, so all five feed the same jobs. Where they differ is how and where — how readily they dissolve, how gently they sit, whether they work systemically or locally. Spreading 500 mg across five means no single form has to carry the whole load, which is exactly why a full dose doesn't have to wreck your stomach.

Two capsules once a day. Most people take them 30–60 minutes before bed. With food is fine and gentler if you're sensitive. If magnesium has caught you out before, start with one capsule for a few days, then move up.

Magnesium refills your stores gradually rather than hitting like a sleeping pill. Most people who notice something notice it in weeks two to four of daily use. That's why the guarantee runs sixty days, not thirty.

Magnesium isn't a one-trick mineral.

It's a cofactor in over 300 enzyme systems, which is why low magnesium shows up in so many unrelated-looking places — and why topping it back up tends to be felt in more than one.

bedtime
Sleep

Supports the nervous system settling at the end of the day. Not sedation — just your body doing what it should already be doing at bedtime.

waves
Tension

The jaw you clench in your sleep, the shoulders that never quite drop. Magnesium supports muscle relaxation, which is most of what tension is.

pulse_alert
Cramps and twitches

Muscles need magnesium to release, not just contract. Supports normal muscle function — night cramps, restless legs, the eyelid flicker.

heart_check
Heart

Your heart is a muscle and runs on the same mineral as the rest. Magnesium supports normal cardiovascular function, day in and day out.

mood_heart
Stress and mood

Supports a steadier response to daily pressure. The stressors stay the same. How loudly your body reacts to them doesn't have to.

femur_alt
Bones and joints

Works alongside calcium and vitamin D — in fact every enzyme that switches vitamin D into its active form needs magnesium to do it.

bolt_boost
Energy

A required cofactor in ATP production — how your cells actually make energy. This isn't stimulation, it's the machinery working properly.

water_drop
Regularity

Magnesium draws water into the bowel, which is why several forms are used clinically for exactly this. Useful if you're eating less than you used to.

 
 

INGREDIENTS

One serving gives you 500 mg of magnesium more than your full daily need. Plus 72 trace minerals from the sea.

  • Hydroxide (Aquamin)
  • Malate
  • Oxide
  • Citrate
  • Glycinate

THE DIFFERENCE

Most magnesium is made in a factory.

Ours starts in the North Atlantic.

Almost every magnesium supplement on the shelf is a salt manufactured in a plant. The marine magnesium in this bottle isn't. It's drawn from seawater off the Irish coast as magnesium hydroxide — and it doesn't arrive alone.

HOW WE STACK UP

Marine magnesium from seawater carrying 72 trace minerals, plus four complementary forms, totalling a full 500 mg of elemental magnesium in two capsules.

What to expect

This is a habit, not a hit.

Magnesium refills your stores gradually. Here's roughly how it goes — and why we give you sixty days instead of thirty.

  1. check_circle

    WEEK 1

    Just build the habit

    Two capsules, same time each evening. Most people don't feel anything definitive yet, and that's exactly right. If your stomach is sensitive, take them with food or start with one.

  2. check_circle

    WEEKS 2 TO 4

    Where people notice

    The window customers most often describe something shifting in. Usually subtle rather than dramatic — a couple of the small annoyances just stop being a daily event.

  3. check_circle

    WEEK 4 ONWARD

    Point heading

    Magnesium rewards consistency. Taken daily your stores stay full; stop and they drift back down. If nothing's changed by now, use the guarantee — that's what it's for.

FREQUENTLY ASKED QUESTIONS

It's a full daily value, and above the 350 mg upper limit set for supplemental magnesium back in 1997 — a figure based on digestive tolerance rather than safety. In April 2025 the industry's own safety review raised its recommended safe upper level to 500 mg for healthy adults. If you have kidney issues or already take another magnesium, speak to your doctor.

It pairs fine with most daily supplements including vitamin D, calcium and omega-3s. If you're on prescription medication, check with your pharmacist — magnesium can interact with certain antibiotics, bisphosphonates, diuretics and blood pressure medicines.

Usually one of two reasons: the dose was smaller than the front of the label suggested, or it was a single synthetic form that didn't suit you. This is 500 mg elemental — a full daily value — across five forms, led by magnesium drawn from seawater rather than made in a plant.

That said, if your magnesium intake is already good, more may not do much. Sixty days is enough to find out without gambling.

Magnesium hydroxide extracted from North Atlantic seawater rather than synthesised. Because it comes out of the ocean instead of a reactor, it carries roughly 72 other trace minerals the seawater had concentrated — silicon, boron, selenium, zinc, iodine, manganese and more. A lab-made salt gives you magnesium and nothing else.

Most people take it in the evening, 30 to 60 minutes before bed. There's no rule though — malate is in the formula precisely so it earns its keep during the day too.

Far less than a single-form bottle at the same dose — that's the whole point of spreading 500 mg across five forms. Magnesium naturally draws water into the bowel, so some people notice things moving a little more freely in week one. Taking it with food or starting at one capsule settles it in almost every case.

Email us within 60 days and we'll refund you in full. Keep the bottle — no return needed, opened or not.

No gelatin, gluten, GMOs, artificial additives or unnecessary fillers. Three inactive ingredients total: hypromellose (the vegetable capsule), rice flour and silicon dioxide.
