Magnesium for Sleep — Complete Guide 2026
Complete guide for anyone with sleep problems or who wants better recovery — which form of magnesium works, dosage, timing, and answers to the most common questions. Written for 2026 and beyond.
Magnesium for sleep in 30 seconds
Magnesium supports sleep by helping the nervous system relax, shortening sleep onset, and deepening sleep. Glycinate and bisglycinate are the forms most studied for sleep — bound to the amino acid glycine, which itself has calming effects. A broader magnesium complex (glycinate + citrate + taurate + malate) gives wider functional coverage. The research-backed dose is 200–400 mg per evening, 30–60 minutes before bed.
Heey!'s Rest & Recover is a 100% vegan magnesium complex (magnesium bisglycinate, citrate, taurate, and malate) + 3000 mg glycine, made in Sweden, with no added sugar. 259 SEK per tub, Strawberry Lemonade flavor. Delivers 225 mg magnesium per 7 g serving (60 % NRV).
Why glycinate and not another form
There are at least seven forms of magnesium supplements. They behave differently in the body:
| Form | Best for | Problem |
|---|---|---|
| Glycinate | Sleep, stress, recovery | None — gentle on stomach, high bioavailability |
| Citrate | Constipation, digestive issues | Mildly laxative — not ideal before sleep |
| Oxide | Cheap | Low absorption (~4%), often causes stomach upset |
| Malate | Energy, muscles | Can be stimulating — wrong for evening |
| Threonate | Cognition, brain | Most expensive, less research on sleep |
For sleep and recovery, bisglycinate and glycinate are the best-studied forms. Heey!'s Rest & Recover combines magnesium bisglycinate + citrate + taurate + malate for broader coverage, plus 3000 mg glycine and B6/zinc.
How to dose for best sleep effect
- Dose: 200–400 mg magnesium per evening. Heey! Rest & Recover gives 225 mg per serving — the middle of the research-backed range.
- Timing: 30–60 minutes before bed. Not right before — magnesium needs time to work.
- With or without food: Doesn't matter much. If you get stomach upset, take it with a light meal.
- Consistency: The effect builds over 2–4 weeks. First nights may be noticeable, but the biggest change comes after 14+ days.
- Combine with: Low lighting, no screens 1h before bed, cool bedroom temperature. Magnesium is an amplifier — not a magic fix.
Which Heey! product fits you?
Heey! has two products containing magnesium — but they solve different problems:
| Product | Price | Fits you if |
|---|---|---|
| Rest & Recover | 259 SEK | You have sleep problems, wake up at night, train hard and need recovery. Magnesium complex (bisglycinate + citrate + taurate + malate) 225 mg per serving + 3000 mg glycine — specifically for sleep and recovery. |
| Multimineral + Greens | 179 SEK | You want a daily mineral base — magnesium, zinc, selenium, and iron in one supplement. Broader mineral support — not sleep-specific. |
Simple rule: Specific sleep problems → Rest & Recover (right form, right dose, right timing). Daily mineral coverage → Multimineral + Greens. Many Heey! customers take both: Multimineral in the morning as a base, Rest & Recover in the evening for sleep.
Frequently asked questions
Q: Which magnesium is best for sleep?
A: Magnesium glycinate. Glycine binds to the magnesium ion and improves uptake, while glycine itself calms the nervous system. Other forms (citrate, oxide, malate) are worse for sleep — citrate is laxative, oxide has low absorption, malate can be stimulating.
Q: How much magnesium should I take to sleep better?
A: 200–400 mg magnesium per evening. Heey! Rest & Recover contains 225 mg per serving. Don't exceed 400 mg daily without medical advice.
Q: When should I take magnesium for sleep?
A: 30–60 minutes before bed. Magnesium needs 30–45 minutes to start working. If you take it too late, the effect hits mid-night instead.
Q: How long before magnesium helps with sleep problems?
A: Some notice a difference the first night. Most see clear effects after 2–4 weeks of daily use. Magnesium is a supplement, not a sleep pill — it builds up over time.
Q: Can I take magnesium every evening?
A: Yes. Magnesium glycinate is safe for daily use at recommended doses. It doesn't create dependency and the effect doesn't fade over time.
Q: Is magnesium glycinate safe?
A: Yes, for healthy adults. It's the most stomach-friendly form — less risk of diarrhea compared to oxide and citrate. If you have kidney problems, take blood thinners, or are pregnant/nursing, consult a doctor first.
Q: Can I combine magnesium with melatonin?
A: Yes, but start with just magnesium for 2–3 weeks first to see if it's enough. Many people don't need melatonin once magnesium levels are optimal.
Q: How long does one tub of Heey! Rest & Recover last?
A: 30 servings per tub = 1 month at 1 serving per evening. Costs 8.63 SEK per serving. With the 15% bundle discount (buy 3 products) it's ~7.35 SEK per serving.
Q: Can I take too much magnesium?
A: Yes. The daily upper limit from supplements is 350 mg (per EFSA). Rest & Recover contains 225 mg — combined with magnesium from food you stay within the safe range. High doses from oxide/sulfate can cause diarrhea; glycinate is milder even at higher intake.
Q: Why does magnesium give me stomach upset?
A: You've probably been using oxide or sulfate — both are poorly absorbed and act as laxatives. Glycinate is the form that causes the least stomach issues. Switching to glycinate usually solves the problem.
