Every Ingredient Carefully Chosen
If magnesium hasn't worked for you before, there are two specific reasons and neither of them are your fault. Most supplements use magnesium oxide, absorbed at roughly 4%. The rest use the right form at a dose too low to produce a consistent effect. This formula fixes both. Zero oxide. Three bioavailable forms. 384mg of elemental magnesium — the actual clinical dose.
Magnesium Glycinate
Most magnesium supplements deliver a fraction of what the label promises. Our magnesium glycinate absorbs 6x better than standard magnesium oxide.
Magnesium Malate
Addresses the daytime side of the problem. Supports energy production and muscle recovery so the exhaustion that follows broken sleep starts to lift.
Magnesium Citrate
Highly water-soluble and fast-absorbing. Ensures the cellular magnesium stores your blood test cannot measure are actually restored, not just topped up in the bloodstream.

Together: 384mg elemental magnesium per serving. The clinical dose. Zero oxide.
What Sets Our Magnesium Apart
If you've tried magnesium before and felt nothing, these are the specific reasons why and why this formula is built differently.
Zero Magnesium Oxide
Most supplements use magnesium oxide. It looks impressive on a label. Your body absorbs 4–10% of it. The rest passes straight through. Ambrosia contains zero oxide because a form your body cannot absorb is not a dose, it's a waste.
Clinically Effective Dose
Most supplements deliver 100–150mg of elemental magnesium. Ambrosia delivers 384mg, the dose level used in clinical research in forms your body can actually absorb.
Three Forms. One System.
Your sleep problem is not one problem. Glycinate supports nervous system calm through the night. Malate addresses the energy deficit that follows broken sleep. Citrate replenishes the cellular stores that deplete silently over time. One form cannot do all three.
The Test Your Doctor Uses Cannot See This
Standard blood tests measure magnesium in your blood. Only 1% of your body's magnesium is in your blood. The other 99% is in your cells and that's where the depletion that drives broken sleep actually happens.

"I honestly didn't think anything was going to help at this point. I'd had broken sleep for years since my menopause and my GP just kept telling me my bloods were fine. I tried the melatonin, tried a magnesium I bought from CVS, took it for weeks and felt absolutely nothing so I stopped. My daughter sent me this after reading something about the different forms of magnesium and how most of them don't actually absorb properly. I thought fair enough, I'll give it one more go. I can't say exactly when it changed but by the end of the second week I was having nights where I just... slept. Woke up and it was light outside. I actually didn't know what to do with myself. I'm not going to say it's fixed everything because I still have the occasional bad night but it's nothing like before. I feel like myself again for the first time in years and I didn't realise how much I'd missed that until it came back."

"Been waking up at 3am basically every night for the better part of two years. Wide awake, brain already going, absolutely no chance of getting back to sleep. Tried everything people suggest. The magnesium from Amazon did absolutely nothing, didn't even bother finishing the bottle. Started this about 6 weeks ago mainly because my wife was fed up of me being a nightmare in the mornings lol. I didn't notice anything the first week and nearly packed it in but stuck with it. Then one morning I realised I hadn't done the thing I always do where I work out how many hours sleep I can still get if I fall asleep RIGHT NOW. I'd just woken up and it was morning. That sounds small but if you have this problem you'll know exactly what I mean. Still early days but feel like a different person honestly."

"Skeptical doesn't cover it. I'd tried magnesium before, twice actually, different brands, and both times I felt absolutely nothing and assumed it just wasn't for me. What made me try this one was the explanation about magnesium oxide and how most supplements use a form your body barely absorbs. I looked it up and it's accurate so I figured maybe I'd been taking the wrong thing all along. I'm on my second bottle now. Sleep is genuinely better, not perfect but so much more consistent than before. The thing that surprised me most was the afternoons. I used to hit a wall every single day around 2 or 3pm and need coffee to get through it. That's basically gone now. Mentioned it to my sister who has the same sleep issues and she's ordered some. That's probably the best review I can give"

What Happens And When
This is not melatonin. There is no hit on night one. What you'll notice is what starts to stop happening, usually in week two.
The Foundation
Magnesium levels begin rebuilding. Most people notice nothing dramatic — and that's exactly right. Your system is recalibrating. Take it every night regardless.
First Signals
This is when most customers notice something has changed. Not a dramatic shift — a quieter one. You got through the night without checking the clock. You woke up and didn't immediately feel behind. Small things. The right things.
The Shift
Where it tends to click. Sleep becomes more consistent. The 3am wake-up starts to fade. You wake up and notice — for the first time in a long time — that you feel like yourself.
The New Normal
Sleep stops being something you manage and starts being something that works. Energy is more even. The baseline is calmer. You stop noticing the problems you used to track.

Are magnesium deficient
Modern diets and soil depletion have quietly lowered dietary magnesium. Most people have no idea their intake is falling short and a standard blood test won't tell them.

Of body magnesium is in your blood
Standard blood tests only measure what's in your bloodstream. The other 99% is in your cells where the depletion that disrupts sleep actually happens.

Absorbed by most magnesium supplements
If you've tried magnesium and felt nothing, this is why. Most people never had a meaningful dose reach their cells.
0mg
Clinically dosed elemental magnesium
A 2025 clinical trial found magnesium glycinate significantly reduced insomnia severity. Most supplements deliver just 100–150mg.

Questions? We Have Answers.
I've tried magnesium before and it did nothing. Why would this be different?
+
Almost certainly because you took magnesium oxide — the form most supplements use because it's cheap. Oxide absorbs at 4–10%. Your body eliminated most of what you took before it could do anything. Ambrosia uses glycinate, malate, and citrate — organic forms that absorb at up to 90%. You've essentially never had a real dose of magnesium your body could use. This is different.
How much should I take per day?
+
Take 3 capsules once per day. This delivers 1800mg of total magnesium from three premium forms, providing 384mg of elemental magnesium — well within the recommended daily range for most adults. No complicated dosing, no need for extra capsules throughout the day. If you are new to magnesium we recommend you start with 1-2 capsules in the first week and work yourself up to 2-3.
Will this cause diarrhea or upset my stomach?
+
Unlikely. The diarrhea reputation comes from magnesium oxide and high-dose citrate taken in isolation. Ambrosia is led by glycinate — the form specifically known for being the gentlest on the stomach. At the doses in our formula, GI side effects are rare. If you're particularly sensitive, take with food.
How long until I notice a difference?
+
Most customers notice the first changes in week two — fewer middle-of-night wake-ups, a calmer baseline at bedtime, less tension in the morning. The full shift tends to happen at weeks three to four. Magnesium isn't a sleeping pill. It's a system restore. What you notice is what stops happening rather than what starts.
Is this a sleeping pill? Will I feel groggy?
+
No. Magnesium doesn't sedate you — it supports the system that controls your stress response and recovery. You won't feel it knock you out. What you'll notice, over time, is that sleep becomes easier to reach and easier to keep. No grogginess. No dependency. No prescriptions. Just your body doing what it was designed to do.
Why three forms instead of just glycinate?
+
Glycinate is the best form for sleep and calm — it leads the formula at the highest dose. But malate supports energy production and muscle recovery during the day, and citrate ensures complete magnesium replenishment. One form addresses one dimension. Three forms address the system.
How do I know this is real glycinate and not buffered with oxide?
+
Many supplements label themselves 'glycinate' but bulk up the formula with cheap oxide to inflate the numbers. Ambrosia's Supplement Facts panel shows the exact dose of each individual form — glycinate, malate, and citrate. No oxide anywhere in the formula. What you see is what's in the capsule.
My doctor tested my magnesium and said my levels are normal. Do I still need this?
+
Standard blood tests are unreliable for assessing magnesium status. Only 1% of your body's magnesium is in the blood — the rest is in your cells, bones, and muscles. A 'normal' serum result tells you almost nothing about your actual magnesium status at the cellular level. Many people with broken sleep, muscle tension, and persistent fatigue have normal serum results but meaningful depletion where it counts.
Can I take this with melatonin or other supplements?
+
Yes. Magnesium and melatonin are complementary — magnesium supports the system that produces melatonin naturally, so they work in the same direction. It pairs well with vitamin D, zinc, and most common supplements. If you're on prescription medication — particularly antibiotics or thyroid medication — take Ambrosia 2 hours apart and consult your doctor if uncertain.
How much should I take per day?
+
Take 3 capsules once per day. This delivers 1800mg of total magnesium from three premium forms, providing 384mg of elemental magnesium — well within the recommended daily range for most adults. No complicated dosing, no need for extra capsules throughout the day. If you are new to magnesium we recommend you start with 1-2 capsules in the first week and work yourself up to 2-3.

I nearly didn't bother after trying magnesium before and feeling nothing. Week two I slept through the whole night. My husband noticed before I even said anything. Haven't looked back.
