Take three capsules daily with a glass of water, preferably with a meal or about an hour before bed.
Primus Magnesium Glycinate delivers 400mg of elemental magnesium bound to glycine — the gentle amino acid that makes this form far more absorbable than common magnesium oxide or citrate, without the laxative effect.
Once absorbed, magnesium goes to work where your body needs it most. It helps relax the smooth muscle in your blood vessel walls to support healthy blood pressure, calms an overactive nervous system to ease stress and tension, and supports the muscle and nerve signaling behind restful sleep and cramp-free nights.
Most customers notice a calmer body within the first week, with deeper sleep and steadier energy building over 2-4 weeks of consistent use.

Each daily serving (3 capsules) contains:
- 400mg elemental magnesium (as fully chelated magnesium glycinate)
- 5mg Vitamin B6 (as Pyridoxal-5-Phosphate, the active form)
- 2,250mg total magnesium glycinate compound for maximum absorption
Free from: wheat, gluten, soy, dairy, tree nuts, magnesium oxide, magnesium stearate, silicon dioxide, artificial colors, flavors and preservatives.
No fillers. No synthetic additives. Just the absorbable form of magnesium your body actually uses.
Third-party tested for purity, potency, and safety in a GMP-certified facility.
Is this really magnesium glycinate, or just magnesium oxide with a fancy label?
Yes — it's real, fully chelated magnesium glycinate, where each magnesium atom is bound to two glycine molecules. That binding is what makes it so absorbable and gentle on the stomach. We deliberately don't use magnesium oxide (poorly absorbed, often laxative) or magnesium citrate (better than oxide, but still loose-stool prone for many people). Check the supplement facts — 400mg elemental magnesium, glycinate form, no fillers.
How long before I notice a difference?
Most customers feel something within the first week — a calmer body in the evenings, less muscle tension, deeper sleep. Effects on blood pressure and stress regulation build more gradually, with most people seeing the strongest results between 4-8 weeks of consistent daily use. Magnesium works best when your body has a steady supply, so taking it every day matters more than the exact time of day.
When should I take it — morning or night?
Most customers take all three capsules in the evening, about an hour before bed, because that's when the calming effect is most noticeable. You can also split the dose — one or two capsules with dinner, the rest before bed — if you want steadier coverage through the day. Take it with a meal either way; magnesium is better absorbed with food.
Can I take this with my blood pressure medication?
Many customers take magnesium alongside their existing medications without issue. Always check with your doctor first — magnesium can be supportive of healthy blood pressure, and your provider may want to monitor that as you start. Never stop or change any prescription on your own.
Will this make me have to run to the bathroom like other magnesium I've tried?
No — that's the laxative effect from magnesium oxide and (to a lesser extent) magnesium citrate, the cheap forms used in most drugstore products. Glycinate is the gentlest absorbable form. The glycine binding lets it pass through your gut wall cleanly without pulling water into the bowels. Most customers report no digestive issues at all, even at the full 3-capsule serving.
What's your money-back guarantee?
We offer a full 60-day money-back guarantee. If you don't feel a difference — calmer body, better sleep, eased tension, or steadier overall well-being — send the bottles back, even empty, for a full refund. No questions asked. We're confident because magnesium glycinate genuinely works, and most customers reorder before their first bottle runs out.

Took magnesium for years and never felt anything from it. Switched to this one because someone in my BP forum recommended it. Six weeks in, I'm sleeping like I did in my 30s and my readings have been trending the right direction. Wife says I'm easier to live with too.

I'm a runner. 56 years old, still putting in miles, but the leg cramps at night were unbearable. Calf would lock up and I'd be standing on the cold floor at 2am. Started this six weeks ago. Cramps stopped almost completely. Wish I'd known about magnesium years ago.

59. Woke up at 3am like clockwork for the last ten years. Tried melatonin, sleep teas, the whole drugstore aisle. Started taking three of these before bed. By the second week I was sleeping through the night again. Still kind of can't believe it.

My doctor told me my blood pressure was creeping into the danger zone last year. Started taking magnesium glycinate alongside the changes she recommended. Four months in, my numbers look completely different and I have energy I haven't had in years. Doc was impressed.

After menopause my whole nervous system felt cranked up. Anxious for no reason, tense shoulders, mind racing at night. A friend told me magnesium glycinate is what doctors actually recommend. Three weeks in and I feel like myself again. Sleep is better too which I did not expect.

83 years old and my son keeps track of my health more than I do. He read about magnesium and ordered me a bottle. Three months later I sleep through the night, my legs don't cramp anymore, and I have steadier energy through the day. My son says I look 10 years younger.

Nearly half of adults don't get enough magnesium. Here's what most people don't realize
You probably already know about diet. About exercise. About cutting back on salt — you've been told all of it. What you haven't been told is that one of the most important minerals for blood pressure, sleep, and calm is the one most people are quietly running low on.
Magnesium is involved in over 300 processes in your body — including the ones that relax your blood vessels, calm your nervous system, and let your muscles recover overnight. But modern diets, soil depletion, and chronic stress drain magnesium faster than most people replace it. Population health studies estimate nearly half of adults don't get enough magnesium from food alone — and the rate is even higher among adults over 50.
When magnesium runs low, the symptoms show up everywhere. Blood vessels stay tight. The nervous system stays on high alert. Muscles cramp at night. Sleep gets shallow. Most people blame stress or age — but it's often a mineral they've been missing for years. Primus Magnesium Glycinate gives your body the most absorbable form at the 400mg dose clinical research has consistently used.
Why Most Magnesium Supplements Never Reach Your Bloodstream.
If you've tried magnesium before and felt nothing, it wasn't your fault. Most cheap supplements use magnesium oxide — the form found in nearly every drugstore bottle on the shelf. Your body absorbs only about 4% of it. The rest passes straight through, often causing the digestive discomfort magnesium is infamous for.
Magnesium glycinate is different. Each magnesium atom is bound to two molecules of glycine — a gentle amino acid that escorts the magnesium directly into your bloodstream. Absorption jumps from 4% to over 80%. No laxative effect. No stomach upset. Just the 400mg of elemental magnesium your body can actually use.
This is the same form clinical research has used for decades. The same form magnesium experts and integrative doctors recommend. The same form your body recognizes — because it's chemically closest to the magnesium found in food.
Results Build With Consistency
Real support builds over weeks, not overnight.
The foundation
You take your first dose. Magnesium begins entering your bloodstream within hours and starts replenishing what your body has been quietly running low on. Nothing dramatic yet — but the foundation is being laid.
The first subtle shifts
Most people notice it first in the evenings. A calmer body. Shoulders that don't feel as tight. An easier transition into sleep. Some sleep deeper than they have in months. If you were noticeably deficient, the shift can be surprising.
Calmer days, deeper nights
Magnesium has had two weeks to reach steady levels in your system. Most users report fewer cramps and twitches, a quieter mind during the day, and noticeably better sleep quality. Stress feels easier to manage. Your nervous system is starting to operate the way it's supposed to.
Cardiovascular support builds
Around the one-month mark, the effects on blood pressure and overall cardiovascular function become more measurable. Many users see steadier readings, calmer resting heart rates, and a stronger sense that their body is regulating itself better. The mineral is doing its full job — not just at night, but all day.
Your new baseline
By 8 weeks, magnesium is fully integrated into your daily systems — sleep, stress response, muscle recovery, cardiovascular regulation. This is the point most users decide whether to continue, but most don't have to think about it. The body simply functions better. If you don't feel a real difference, you are still inside the full 60-day refund window — no questions asked.

Without the right support
How Primus Compares to What You've Probably Already Tried
Not all magnesium is the same. The form, the dose, and what's in the bottle alongside it make all the difference.
People who want better sleep, calmer days, fewer cramps, and steady blood pressure support— all in one bottle, without the digestive issues.
People looking for a cheap, occasional laxative. Poorly absorbed, so not much of the magnesium actually reaches your body.
People needing short-term digestive relief. Slightly better absorbed than oxide, but still causes loose stools at meaningful doses.
People who want general magnesium coverage without thinking too hard about it.
The Numbers Behind Magnesium
Magnesium is one of the most studied minerals in human health. The research is consistent: better sleep, calmer stress response, healthier blood pressure, and improved muscle recovery — when taken at the right dose, in the right form.
