Complete reference guide for anyone researching magnesium glycinate,what it is, how it differs from other forms, dosage, safety, and answers to the most common questions. Written for 2026 and beyond.
Magnesium glycinate in 30 seconds
Magnesium glycinate (also called magnesium bisglycinate) is magnesium bound to the amino acid glycine. The binding makes it gentle on the stomach and gives it the highest absorption rate among common magnesium forms. It's the form research most consistently links to sleep, stress, and recovery,partly because glycine itself has calming effects on the nervous system. The research-backed dose is 200–400 mg elemental magnesium per day.
Heey!'s Rest & Recover is a 100% vegan magnesium complex built around magnesium bisglycinate plus three other forms (citrate, taurate, malate) and 3000 mg glycine. 225 mg magnesium per 7 g serving (60% NRV). 259 SEK per pouch, 30 servings, Strawberry Lemonade flavor, made in Sweden, no added sugar.
What is magnesium glycinate?
Magnesium is an essential mineral involved in over 300 enzymatic reactions in the body,muscle function, nerve signaling, energy production, and sleep regulation. The catch is that magnesium doesn't exist on its own in supplements; it's always bound to another molecule, and that binding changes how well your body absorbs it.
In magnesium glycinate, the magnesium ion is bound to two glycine molecules (which is why it's also called "bisglycinate"). Glycine is a small amino acid that the body uses for many functions, including as an inhibitory neurotransmitter that calms the central nervous system. Two effects at once: gentle absorption of the magnesium, plus a mild calming effect from the glycine.
How does it compare to other magnesium forms?
There are at least seven common forms of magnesium supplements. They behave differently in the body:
| Form | Best for | Notes |
|---|---|---|
| Glycinate / Bisglycinate | Sleep, stress, recovery | High absorption, gentle on stomach, mildly calming |
| Citrate | Constipation, digestive support | Mild laxative effect,useful for some, not ideal before sleep |
| Oxide | Cheap supplement filler | Very low absorption (~4%), often causes stomach upset |
| Malate | Energy, muscle pain | Can be stimulating,wrong choice for evening |
| Threonate | Cognitive function | Crosses the blood-brain barrier, but expensive and less researched |
| Taurate | Cardiovascular support | Bound to taurine, may help blood pressure regulation |
| Sulfate | Topical (Epsom salt) | Not for oral use,strong laxative effect |
For sleep, stress, and recovery, glycinate (bisglycinate) is the form most studies use. A magnesium complex that combines glycinate with citrate, taurate, and malate gives broader functional coverage in one dose.
How to dose magnesium glycinate
- Dose: 200–400 mg elemental magnesium per day. The EFSA upper limit for supplemental magnesium is 350 mg/day for adults. Heey!'s Rest & Recover provides 225 mg per serving,the middle of the research-backed range.
- Timing: Evening, 30–60 minutes before bed if using for sleep. Morning or afternoon if using for general recovery and stress.
- With or without food: Either works. Magnesium glycinate is gentle enough to take on an empty stomach.
- Consistency: Effects build over 2–4 weeks. Don't judge it on one night.
- Combine with: Adequate hydration. Magnesium works best when the rest of the system is in balance.

Frequently asked questions
Q: What is magnesium glycinate?
A: Magnesium glycinate (also called bisglycinate) is magnesium bound to the amino acid glycine. The binding gives it the highest absorption rate among common magnesium forms and a gentle effect on the stomach.
Q: Is magnesium glycinate better than other forms?
A: For sleep, stress, and recovery,yes. Glycinate has the highest absorption and the gentlest gastrointestinal profile. For constipation, citrate may be more useful. For sheer cost, oxide is cheapest but has very low absorption.
Q: How much magnesium glycinate should I take per day?
A: 200–400 mg of elemental magnesium per day, depending on diet and use case. The EFSA upper limit for supplemental magnesium is 350 mg/day for adults. Heey!'s Rest & Recover provides 225 mg per serving.
Q: When is the best time to take magnesium glycinate?
A: 30–60 minutes before bed if using for sleep. Morning or afternoon if using for general recovery, stress, or muscle function. Daily consistency matters more than exact timing.
Q: Can magnesium glycinate cause side effects?
A: Side effects are uncommon at recommended doses. Glycinate is the most stomach-friendly form,far less likely to cause diarrhea than oxide or sulfate. Higher doses (above 400 mg/day) may cause loose stools in some people.
Q: Is magnesium glycinate vegan?
A: It depends on the source. The magnesium itself is a mineral, but the glycine binding can come from animal or plant sources. Heey!'s Rest & Recover uses 100% vegan-sourced magnesium bisglycinate.
Q: Can I take magnesium glycinate every day?
A: Yes. Magnesium glycinate at recommended doses is safe for daily long-term use. The body doesn't build tolerance, and effects don't fade over time.
Q: Does magnesium glycinate help with anxiety?
A: The research is suggestive but not conclusive. Low magnesium levels are associated with higher stress and anxiety markers, and supplementation can help correct that. Glycine itself has mild calming effects on the nervous system, which may amplify the benefit of the glycinate form specifically.
Q: Can I combine magnesium glycinate with other supplements?
A: Generally yes. Common combinations include magnesium + zinc (Heey! Rest & Recover includes zinc), magnesium + B-vitamins, and magnesium + melatonin. Avoid taking magnesium at the exact same time as large doses of calcium or iron,space them out by at least 2 hours.
Q: How long does one pouch of Heey! Rest & Recover last?
A: 30 servings per pouch,one month at one serving per evening. Approximately 8.63 SEK per serving.
