Your body absorbs less magnesium every decade and you feel it.

Image with text

As you age, your gut absorbs less magnesium, your bones store less, and your kidneys excrete more. Up to 60% of adults already fall short of their daily magnesium needs — and that gap widens with every passing decade, affecting muscles, sleep, and bone health. The cause isn't diet alone. After 40, the specific proteins responsible for pulling magnesium across your gut wall become less active — meaning the same food and supplements deliver measurably less to your bloodstream each decade. Add in the daily drains — coffee, alcohol, stress, and exercise all accelerate magnesium loss — and the deficit compounds quietly in the background. Most people never connect the dots. The poor sleep, the muscle cramps, the afternoon crash — they put it down to getting older. But it's not age. It's depletion. And depletion has a fix.

Why 12 Forms Of Magnesium

Image with text

If you've tried magnesium before and felt nothing — that's probably why. Single form magnesium only targets one system. Your sleep, your mood, your muscles, and your heart rhythm all respond to different forms. Our 12 in 1 formula covers every system at once so nothing gets left behind.*

Brain
→ Magnesium Glycinate (calm & anxiety)
Heart → Magnesium Taurate (rhythm & cardiovascular)
Muscles → Magnesium Malate (relaxation & recovery)
Bones → Magnesium Carbonate (density & strength)
Gut → Magnesium Oxide (gentle digestion)
Nervous system → Magnesium Aspartate (stress response)
Joints → Magnesium Chloride (mobility & inflammation)
Cells/Energy → Magnesium Orotate (cellular ATP & energy)
Kidneys → Magnesium Citrate (detox & fluid balance)
Blood vessels → Magnesium Gluconate (circulation)
Immune system → Magnesium Ascorbate (immune defence & antioxidant)
Skin/tissue → Magnesium Lactate (gentle absorption & tissue repair)

Have Questions? We Have Answers.

What makes this magnesium different from the ones I've already tried? +


Most magnesium supplements contain a single form — usually Oxide or Glycinate. The problem is that absorption depends on your individual gut biology, diet, and timing. If that one form doesn't absorb well for you, you feel nothing. Our 12-in-1 formula works across 12 different absorption pathways simultaneously, so your body gets what it needs regardless of individual differences. If you've tried magnesium before and it didn't work — this is why.

How long until I see results? +


It depends on what you're taking it for — and how depleted you are to begin with. Most customers notice the first changes within 1–2 weeks: sleep quality improving, leg cramps reducing, and waking up less stiff in the morning. These tend to be the earliest and most noticeable shifts.


Deeper effects — reduced background anxiety, more consistent energy levels, faster workout recovery — typically build over 3–4 weeks of consistent use. Magnesium isn't like a painkiller that works in an hour. It works by restoring what's been depleted over months or years, which means the longer you've been deficient, the more noticeable the change once levels are restored.

Is it safe to take with medication? +

Magnesium is an essential mineral your body produces naturally — it's not a stimulant, hormone, or synthetic compound. For the vast majority of people, it is safe and well-tolerated at the recommended dose.

That said, magnesium can interact with certain medications. If you are taking any of the following, please speak to your GP before starting:

  • Antibiotics (particularly tetracyclines and quinolones — magnesium can affect absorption)
  • Blood pressure medication (magnesium has a natural blood pressure-lowering effect)
  • Diuretics (can affect how your kidneys handle magnesium)
  • Thyroid medication (timing of doses may need to be separated)

If you are pregnant, breastfeeding, or managing a diagnosed condition, we always recommend checking with your doctor first. Otherwise, for healthy adults taking no regular medication, this formula is specifically designed to be gentle and well-tolerated — including a ramp-up protocol for the first week to help your body adjust.

Are there any side effects? +


For most people, none at all. Magnesium is an essential mineral your body already needs — this formula simply restores what's been depleted. It contains no stimulants, synthetic hormones, or artificial fillers.

A small number of people experience looser stools in the first week, particularly if they've never taken magnesium before. This is a well-known adjustment response, most commonly associated with the Citrate and Oxide forms in the formula. It typically settles within a few days.

To minimise this, we recommend starting with 1 capsule for your first week, then moving to the full serving of 2. Your gut adjusts, and the results are worth it. If you are pregnant, breastfeeding, or on regular medication, please consult your GP before use.

What's your money-back guarantee? +

We back this product with a 60-day, no-questions-asked guarantee. If you try it and don't feel a difference, contact us within 60 days of purchase and we'll refund you in full — no returns required, no hoops to jump through.

We offer this because we're confident in what's inside the capsule. Magnesium deficiency is real, the formula is dosed for effect, and the results speak for themselves. But if for any reason it doesn't work for you, you shouldn't pay for it. Simple as that.

WOW! I'm floored by this multi magnesium supplement! My hair was becoming brittle & breaking; My fingernails had ridges forming; My skin looking dull. I began taking this 6 months ago. I was looking to fill a need for my aging body. As a retired disabled nurse I didn't hold out hope for relief. By the end of 30 days I noticed my skin feeling like skin again. I noticed by the 2nd month my hair fuller and not brittle/breaking anymore. And by month 4? The ridges in my nails have greatly receded. Month 6 and I have regained what I thought I had lost to age and menopause. I'm truly grateful to have found this. Great product and a Great price. Subscribe after you have had at least 3 months of taking. I hope it does for you what it has done for me and my senior MIL.

Wow!! This magnesium supplement has been life changing for me! I get vestibular migraines and boy when they come on, they are excruciating! I get extremely dizzy, nauseous, my neck stiffens and I feel like my body shuts down and the pain is unreal. I even make sure I focus on eating magnesium rich foods regularly and it’s like my body just does not absorb magnesium like it should. I have literally bought probably 20+ different brands of magnesium in the last 5-6 years searching for “the one” and this IS IT!! When my migraines hit, I have to take a LONG bath and I use 6-8 Cups of magnesium chloride and it really works. I soak for about an hour and walk out a new person but magnesium chloride is pretty spendy especially needing to use so many cups. Since starting this, it’s like the tightness in my neck has completely gone away and I haven’t had a single migraine let alone a headache. This magnesium doesn’t make me sleepy like it does some people. It knocks my husband out though lol. I have been taking 2/night just to help raise my levels but even 1 is sufficient. I have my teen daughter, husband and tween son taking one every night. I hope they never stop making this. I will buy this for the rest of my life!

I’ve tried several magnesium supplements over the years, but this one really stands out. I like that it includes multiple forms (glycinate, citrate, malate, taurate, etc.) instead of just one type. It feels like a more well-rounded formula. I primarily take it in the evening, and I’ve noticed I feel more relaxed and fall asleep easier. It’s not a “knock you out” feeling — just a calm, steady wind-down.
