What is in the formula
“I've had the 3am wake-up thing for like 3 years. Started taking these and I honestly can't believe the difference. Sleeping straight through now. My wife said 'you've been so much calmer lately' before I even told her I started taking anything.”

Common questions
Most customers notice improved sleep quality within 1-2 weeks of consistent use. Muscle relaxation and stress benefits are often felt within the first few days. Individual results may vary.
Take 1 to 2 capsules once or twice daily with warm water. Best results are achieved when taken 30-60 minutes before bed. Do not exceed 4 capsules per day.
Magnesium Glycinate is generally safe to combine with most supplements. If you take medications or have a medical condition, consult your healthcare provider before starting.
Magnesium Glycinate binds magnesium to the amino acid glycine, making it 3-4x more bioavailable than cheap magnesium oxide. It is also the gentlest form on the gut with no laxative effect.
30-day money-back guarantee. Email support@SELERA.com for a full refund — no photos required, no restocking fee.
Every batch of SELERA Magnesium Glycinate is independently tested for heavy metals and harmful compounds by certified agencies in the UK, Europe and the US.
Magnesium Glycinate (Bisglycinate) is bound to glycine for 3-4x better absorption than magnesium oxide. Your body actually uses what you take.
We are so confident in our formula that if you do not feel the difference in 30 days, we refund you in full. No questions, no photos required.
Sleep Support
Magnesium activates the parasympathetic nervous system — your "rest and digest" mode. It calms the brain's overactive stress circuits so you can fall asleep faster and stay asleep longer.
Stress & Calm
Chronic stress burns through magnesium stores. Low magnesium amplifies your stress response. SELERA breaks this cycle, keeping your nervous system regulated throughout the day.
Muscle Recovery
Magnesium is essential for muscle contraction, relaxation, and protein synthesis. Athletes and active adults see dramatically faster recovery when their magnesium levels are optimal.
Simple daily routine. Takes 30 seconds.
Take 1-2 capsules
Take 1 to 2 capsules with warm water. Start with 1 capsule to assess tolerance. You can increase to 2 capsules after a few days.
Best timing: before bed
For sleep support, take 30-60 minutes before bed. For muscle recovery, take after exercise. Can also be taken in the morning for stress support.
Stay consistent
Most people notice results within 1-2 weeks of daily use. Magnesium levels build over time — consistency is key to experiencing the full benefit.
Pure Magnesium Glycinate. Nothing unnecessary.
Magnesium Glycinate
Core ActiveThe star of the formula. Magnesium Bisglycinate is the most bioavailable and gentle form of magnesium, bound to the amino acid glycine for superior absorption and zero laxative effect.
Glycine (amino acid)
Absorption CarrierNot just a carrier — glycine itself supports sleep quality, collagen production, and a calm nervous system. It enhances the magnesium while providing its own benefits.

New York, NYI've had the 3am wake-up thing for probably 3 years now. Could not figure out why. Started taking these about 2 weeks ago and I honestly cannot believe the difference. Sleeping straight through now. My wife actually said "you've been so much calmer lately" before I even told her I started taking anything lol. Will keep buying.

Austin, TXLeg cramps every single night for like a year. My doctor mentioned it could be low magnesium so I started looking into it. Tried the glycinate form specifically after reading it absorbs better and honestly within maybe 5 or 6 days the cramps stopped. Just... gone. I'm on my second bottle now and haven't had one since. Kind of annoyed I didn't try this sooner tbh.

Los Angeles, CAI've tried basically every sleep thing out there. Melatonin made me feel hungover in the morning every time. ZzzQuil knocked me out but felt terrible. This is completely different. I take 2 capsules maybe 45 min before bed and my brain just kind of... quiets down. I still feel like myself, just not wound up. Been doing it for a month and it's become part of my routine.

Portland, ORI lift 5x a week and soreness was really starting to grind me down. A friend who's a personal trainer told me to try magnesium glycinate specifically (not just any magnesium). Been taking it for about 6 weeks now. Recovery is genuinely better. Less stiffness the next morning, I can train harder. My coach noticed I was bouncing back faster and asked what changed.

Chicago, ILI was pretty skeptical going in, not gonna lie. I've always been a high-strung person and sleep has always been rough for me. Figured I'd try this after reading about how magnesium supports the nervous system. Three weeks in and I fall asleep way faster. The nighttime mental chatter has really calmed down. No stomach issues which was my main concern with supplements.

Miami, FLI'm pretty selective about supplements. The first thing I check is whether it's third party tested for heavy metals. Most brands aren't or they just say they are with no proof. Found that this is tested by agencies in the UK, Europe and the US and that actually moved me to buy it. The results have backed up the quality too. Sleep is better, I feel less tense during the day. Already on bottle 2.

Seattle, WAEvery morning I used to wake up with my jaw clenched and shoulders up near my ears. I didn't even realize how tense I was until someone mentioned it could be magnesium. Started taking this before bed and within maybe 2 weeks I noticed I was waking up relaxed. Like physically loose. It sounds small but it's made my whole morning better.

Denver, COI'm 42 and figured bad sleep was just part of life now. My buddy kept telling me to try magnesium glycinate and I kept ignoring him for like 6 months. Finally caved and bought a bottle. Two weeks later I'm sleeping deeper than I have in years. I actually feel rested when I wake up. Haven't needed my afternoon coffee in weeks. Should've listened to my buddy sooner.

Nashville, TNGot the 3 pack because it worked out cheaper and I'm glad I went with that. Capsules are easy to swallow, no weird taste or smell at all. Been taking them for about 5 weeks now. Sleep quality has genuinely improved. I track my sleep with my Garmin and my deep sleep percentage has gone up since I started. Shipping was fast, everything arrived in perfect condition.
