Peer-reviewed research
The science is there.
Magnesium Glycinate isn't a trend. Decades of published research back what it does — and why the form matters.
Superior absorption
Glycinate form shows significantly higher bioavailability than oxide forms in comparative studies.
Journal of the American College of Nutrition
Sleep quality
Magnesium deficiency directly linked to poor sleep quality and insomnia in clinical research.
Magnesium Research Journal
Muscle relaxation
Supplementation shown to significantly reduce muscle cramps and tension in controlled trials.

Deeper sleep via glycine
Glycine — the amino acid in Magnesium Glycinate — independently shown to promote deeper sleep stages.

Stress regulation
Magnesium plays a critical role in regulating the body's cortisol and stress response systems.

Sleep deeper. Wake up restored.
Not all magnesium is created equal. Most brands use oxide — a form your body barely absorbs. Absorva Lab uses pure glycinate for maximum cellular absorption and real, lasting sleep support.

WHAT PEOPLE ARE SAYING
Real results, real people
"
I've tried three different magnesium supplements over the past two years. Nothing came close to this. Within two weeks I was sleeping through the night for the first time in years. I didn't realise how much the quality of the form mattered until I felt the difference.
The unbuffered difference is real. I used to take a cheaper brand and always felt like it wasn't doing much. Switched to Absorva and noticed a genuine shift in my recovery after training. Less soreness, better sleep. Simple.
I was sceptical — I've seen so many supplement brands make big promises. But the 60-day guarantee made it easy to try. Three weeks in and my anxiety before bed has noticeably reduced. I'm calmer, I fall asleep faster, and I wake up actually rested.

COMMON QUESTIONS
Everything you need to know
-
When reading a magnesium label, the number that actually matters is the elemental magnesium figure — in our case, 275mg per serving (3 capsules), or approximately 90mg per capsule. This is the actual amount of absorbable magnesium your body can use. The 2,500mg refers to the total weight of the full compound, magnesium glycinate, which includes the glycine molecule it's bound to. Always look for elemental magnesium when comparing supplements — it's the only number worth comparing.
-
Buffering is a common cost-cutting practice where brands mix true magnesium glycinate with cheaper magnesium oxide. This reduces the cost of production but also reduces the quality and absorption of the final product. Our formula is 100% unbuffered — meaning the magnesium glycinate has not been diluted or mixed with any other magnesium form. What you see on the label is what you get.
-
Magnesium glycinate is a chelated form — bound to glycine, an amino acid — which makes it significantly more absorbable than inorganic forms like magnesium oxide or citrate. It's also far gentler on the digestive system. Unlike magnesium citrate or oxide, glycinate doesn't draw water into the colon, so there's no laxative effect. It's the form most commonly recommended for sleep, stress, and muscle recovery precisely because the absorption is reliable and the tolerance is high.
-
We recommend taking all 3 capsules with your evening meal or 30–60 minutes before bed. Glycine — the amino acid magnesium is bound to — has calming properties that support the nervous system winding down, making an evening dose ideal for sleep. That said, magnesium glycinate is gentle enough to take at any time of day, and some people split their dose across morning and evening depending on what they're using it for.
-
Not necessarily. Many people aren't clinically deficient but are consistently under-replenishing magnesium through diet — particularly if they don't regularly eat leafy greens, nuts, seeds, or legumes. Magnesium is depleted by stress, caffeine, alcohol, and exercise, which means a lot of people are running low without knowing it. If you're experiencing poor sleep, muscle tension, or low energy, low magnesium is worth considering even without a formal diagnosis.
-
It varies by person. Some notice improved sleep quality within the first week. For others, it takes two to three weeks of consistent use before the difference becomes noticeable — particularly for stress and muscle recovery. Magnesium repletion is cumulative, not immediate. The more consistent you are, the better the results — which is why we recommend a full 30-day trial before drawing conclusions.
-
Magnesium glycinate is one of the least likely forms to cause any digestive discomfort. Unlike magnesium oxide or citrate — which can cause loose stools or a laxative effect — glycinate doesn't interfere with water balance in the colon. It can be taken on an empty stomach. If you do experience any sensitivity when starting out, try taking it with food and see if that resolves it.

-
Magnesium glycinate is generally well tolerated. However, magnesium can affect the absorption timing of some medications — including certain antibiotics, diuretics, bisphosphonates, and heart or blood pressure medications. If you're on any prescription medication, check with your healthcare provider before starting. Not recommended for those with severe kidney disease without medical supervision.
