Magnesium is involved in over 300 biochemical reactions in your body, from sleep and stress regulation to muscle function and nerve health. Yet most people are deficient without even knowing it.
But not all magnesium supplements are created equal. Cheap forms like magnesium oxide are poorly absorbed and notorious for causing digestive discomfort.
That's why we use magnesium bisglycinate, a chelated form bound to the amino acid glycine. This pairing is clinically shown to deliver superior absorption while being exceptionally gentle on the stomach. Glycine itself promotes relaxation, making this the ideal form for sleep, stress, and recovery. Every gummy is optimally dosed to ensure you get real, noticeable results

Yes, our magnesium bisglycinate supplement is 100% natural, non-GMO, vegan, and made without any artificial fillers or preservatives. All ingredients are third-party tested for purity and potency in a GMP-certified facility.
Magnesium glycinate is one of the best-tolerated forms of magnesium and is unlikely to cause digestive issues. However, if you're pregnant, nursing, or taking medication (especially blood pressure or heart medications), we recommend consulting your healthcare provider before use, just to be safe
Per serving (2 gummies, 30 servings):
- 400mg magnesium bisglycinate (chelated for high absorption)
- Sugar-free (stevia)
- Pectin base (not gelatin — vegan friendly)
No magnesium oxide. No stearates. No proprietary blends. No artificial colors. No fillers that dilute the dose.
Third-party tested. GMP certified, FDA registered laboratory.
Will this cause diarrhea or upset my stomach?
Very unlikely. Magnesium bisglycinate is specifically known for being the gentlest form on the stomach — unlike cheap magnesium oxide or citrate, which are notorious for causing bloating and loose stools. Our formula is led by bisglycinate for this exact reason. If you've had bad experiences with other magnesium supplements, this is the form for you.
How much should I take per day?
Take 2 gummies approximately 60 minutes before bed. For best results, use consistently for a minimum of 2-4 weeks to allow full tissue saturation. Can also be taken in the morning if nighttime use causes alertness in sensitive individuals.
Should I take it in the morning or before bed?
If you're taking it primarily for sleep, take it 30–60 minutes before bed. For general wellness, stress, or muscle recovery, morning or evening both work well. You can also split the dose — one gummy in the morning, one before bed — though most of our customers prefer taking both gummies together at night.
How do I know this is real magnesium bisglycinate and not buffered with oxide?
Great question — many brands label their product as "bisglycinate" but secretly bulk it up with cheap magnesium oxide to inflate the numbers. Our formula is transparently labeled with the exact amounts of each form. What you see on our Supplement Facts panel is exactly what's inside the gummy. No hidden fillers, no bait-and-switch.
How long until I feel a difference?
It depends on what you're taking it for. Muscle cramps and tension can improve within a few days. Sleep quality typically improves within 1–2 weeks. Stress and mood benefits usually emerge around 2–4 weeks. For full results, we recommend giving it at least 4–6 weeks of consistent daily use. Magnesium is not a sleeping pill, it's a mineral your body needs to build back up over time.
Can I take this with vitamin D, zinc, or other supplements?
Yes. Magnesium and vitamin D are a perfect pair — your body actually needs magnesium to activate vitamin D. Take calcium separately (2–4 hours apart) as they compete for absorption. Same with iron — space them out by at least 2 hours. Melatonin pairs safely with magnesium and can enhance its sleep benefits.
Will this interact with my medications?
Magnesium can interact with certain medications, particularly antibiotics (take 2 hours before or 4–6 hours after), thyroid medication (separate by 4+ hours), and blood pressure drugs. Most interactions are managed through timing, not avoidance. If you're on prescription medication, we recommend consulting your doctor before starting — just to be safe.
"As a specialist I recommend TerraCore Labs Magnesium Bisglycinate to patients struggling with sleep maintenance and nocturnal anxiety. The fully-chelated 400mg dose and zero-sugar formula make it the only gummy I trust for clinical recommendations."

Magnesium Bisglycinate Chelate
Unlike regular magnesium that gets stuck in your gut, this form is wrapped in amino acids so your body actually absorbs it. That means the full 400mg gets into your bloodstream and reaches your brain — not your toilet.
-
Glycine (Chelate Carrier)
Glycine is a natural calming signal in your brain that tells your body it's time to sleep. It lowers your body temperature and cuts stress hormones so you fall asleep faster and stay asleep longer.
-
Natural Raspberry Powder
Real raspberry flavour from actual fruit — no fake flavouring, no sugar, nothing that messes with your sleep. Just the taste that makes you want to take it every night.
-
Stevia & Allulose
Two natural sweeteners that make these taste great without any sugar or blood sugar spike before bed. Your body stays in the perfect state for deep, uninterrupted sleep.

“I’ve tried three different magnesium supplements and they all either did nothing or gave me terrible cramps. TerraCore is the first one that worked. I stopped waking up at 3am after the first week. My husband noticed a difference before I even told him I was taking something new.”

★★★★★
“A product that actually delivers what it claims.” I love that it’s just two gummies and the dose is real — not 100mg hiding behind a nice label. I’m a nutritionist and I was skeptical, but the bisglycinate form and the zero-sugar formula are exactly right. My clients are getting results within the first two weeks.”

TerraCore® is Different From Everything You've Tried
-
Reason 1
A Clinical Dose. Not a Gesture.
Most magnesium gummies on the market deliver 100–200mg — a fraction of the 310–420mg RDA, and nowhere near what’s needed to correct chronic depletion. TerraCore delivers exactly 400mg of verified bisglycinate per two-gummy serving. No underfilling, no proprietary blend opacity, no shortcuts.
-
Reason 2
Targets Sleep and Stress. Together.
Most supplements target one symptom. TerraCore’s bisglycinate chelate works across the nervous system simultaneously — correcting the magnesium deficiency driving muscle tension, the glutamate overactivity causing racing thoughts, and the cortisol dysregulation triggering 3AM wakeups. All in two gummies.
-
Reason 3
No Sugar. No Aftertaste. No Regrets.
Sweetened with stevia and allulose — not glucose syrup, sucralose, or maltodextrin. No glycemic spike before sleep. No chemical aftertaste. The natural raspberry flavor comes from real raspberry powder. The only thing you’ll taste is a supplement that actually respects your body.

They Felt the Shift. You Will Too.
“Finally stopped waking up at 3AM.”
I’ve had this problem for three years. Melatonin made it worse — I’d fall asleep fine then bolt awake at 3 and lie there for two hours. Within ten days of TerraCore, that stopped completely. I genuinely didn’t think anything would fix this.
“A clean product that actually delivers the dose it claims.”
I’m a pharmacist and I was tired of recommending magnesium to patients who came back and said it did nothing. Almost always it was because they were taking oxide at 100mg. The bisglycinate form at 400mg is a different product entirely. TerraCore is what I now point people to.
“My go-to for managing anxiety at night.”
I take SSRIs and adding another capsule felt overwhelming. The gummy format was the only reason I tried it. Now I genuinely look forward to taking these before bed. My anxiety doesn’t spiral the way it used to. Sleep tracker shows more deep sleep than I’ve had in years.
“Subtle at first, but genuinely life-changing over time.”
Week one I wasn’t sure. Week two I slept through the night for the first time in months. By week three I realized I was less irritable, less reactive, and actually present with my kids in the evenings. I can’t attribute it to anything else. It works quietly and then suddenly everything’s just better.
