Discover the “Deep-Sea” Mineral That's Changed The Lives of Over 168,000 Adults

If you eat well, exercise, and still wake up wired-but-tired with restless legs, a 3pm crash, and a mind that won't switch off — you're not broken. You're almost certainly low in one specific mineral most adults have stopped getting from food.

If You're an Adult Feeling “Wired-But-Tired,” Continue Reading…

Most adults are told it's stress, screens, or age. It is — partially. But there's a deeper reason your nervous system can't calm down at night and your energy crashes by mid-afternoon.

A century of intensive farming has stripped our soil of one specific mineral your body burns through faster than you can replace it. The result: an estimated 1 in 2 adults now runs deficient, and almost none of them know it's the cause.

Even with a clean diet, the leafy greens you eat today contain a fraction of the magnesium they did 100 years ago — as the chart shows.

And research shows that when adults don't get enough of this essential mineral, it can lead to symptoms such as:

Symptoms of magnesium deficiency: can't switch off at night, afternoon energy crash, restless legs and cramps, brain fog and low mood

The Missing Mineral

It's called magnesium — and it's the spark for over 300 enzymatic processes in your body. Without it, almost every system that keeps you calm, rested, and energised runs ragged.

Magnesium is responsible for:

  • Calming your nervous system at night
  • Relaxing muscles — including the heart
  • Steady energy production in every cell
  • Healthy sleep architecture & deep REM
  • Regulating mood, focus and stress response

But here's the part most brands don't tell you: magnesium doesn't work alone. It needs trace co-factors — iodine, zinc, selenium, boron — to actually cross into the cells that need it. That's why we paired it with one of the only whole foods on earth that contains all of them.

⚠️

Warning: not all magnesium supplements are absorbed equally. Most use a cheap form (oxide) that passes straight through your gut — which is why you may have tried magnesium before and felt nothing.

Not All Magnesium is Created Equal!

Our Magnesium + Irish Sea Moss uses single-origin magnesium glycinate — the form clinical studies put closest to 80% bioavailability — paired with wild-harvested sea moss for the 92 trace co-factors magnesium needs to actually work.

Why We Made Magnesium + Irish Sea Moss

After years of watching customers come back saying their drugstore magnesium “didn't do anything,” we went looking for the reason. We found two.

One: the form on the label matters more than the dose. We use single-origin magnesium glycinate — chelated to the amino acid glycine for gentle, high-absorption uptake that actually reaches the nervous system.

Two: magnesium needs co-factors. We pair every capsule with wild Irish sea moss, hand-harvested off the west coast of Ireland — a whole food that contains 92 of the 102 minerals your body uses. It's the missing chord that lets magnesium actually do its job.

That's the entire formula. No fillers. No flow agents. No shortcuts.
