Key Takeaways
- Same mineral, different carrier: Magnesium glycinate is magnesium bound to the amino acid glycine (14.1% magnesium by weight at most), while magnesium citrate is bound to citric acid (16.2% magnesium by weight).
- Absorption: Both forms are well absorbed and the difference between them is small; splitting your daily amount into smaller doses absorbs a greater share than one large dose.
- Gut tolerance: Glycinate is very gentle on digestion, whereas citrate draws water into the intestine and may cause loose stools at doses above 200–300 mg elemental magnesium.
- Best use: Choose glycinate for sleep support, relaxation, muscle recovery and long-term daily use; choose citrate for occasional constipation, short-term use or a tighter budget.
- Dosage and timing: Glycinate is typically taken at 200–350 mg elemental in the evening; citrate at 200–300 mg elemental in the morning or as needed; stay within the 350 mg/day supplemental upper limit, with the ICMR-NIN (2020) RDA at 440 mg/day for men and 370 mg/day for women including food.
- Safety note: Magnesium bisglycinate and glycinate are the same compound; if you take blood pressure medication, antibiotics or diuretics, consult your doctor before starting any magnesium supplement.
What's the Difference Between Magnesium Glycinate and Magnesium Citrate?
If you've ever searched for a magnesium supplement, you've likely been overwhelmed by the options — glycinate, citrate, oxide, threonate, taurate, and more. The two most popular forms in India are magnesium glycinate and magnesium citrate, and choosing between them depends entirely on what you want from your supplement.
This guide breaks down the key differences in absorption, benefits, side effects, and best use cases so you can pick the right form for your body. For a deeper dive into magnesium glycinate specifically, see our complete magnesium glycinate guide.
Quick Comparison: Magnesium Glycinate vs Citrate
| Parameter | Magnesium Glycinate | Magnesium Citrate |
|---|---|---|

| Absorption | Well absorbed | Well absorbed, highly soluble |
| Gut tolerance | Excellent — very gentle | May cause loose stools at higher doses |
| Best for | Sleep, calm, muscle recovery, long-term daily use | Occasional constipation, short-term Mg boost |
| Laxative effect | Minimal | Moderate — draws water into the intestine |
| Taste | Neutral (capsules) | Slightly tart/sour (powder forms) |
| Price range (India) | ₹500–₹900 for 60–120 caps | ₹300–₹600 for 60–120 caps |
What Is Magnesium Glycinate?
Magnesium glycinate is a chelated form where magnesium is bound to glycine, a calming amino acid. The bond does two things: it helps the magnesium survive the gut intact, and it adds the independent benefits of glycine, which supports relaxation, sleep quality, and nervous system function.
Because the glycine carrier is gentle on the digestive system, magnesium glycinate rarely causes the stomach upset or loose stools that other magnesium forms can trigger. This makes it the preferred choice for daily, long-term supplementation.
One number worth carrying with you: pure magnesium bisglycinate is 14.1% magnesium by weight at most, because each magnesium ion carries two heavy glycine molecules. A 550 mg capsule of pure bisglycinate therefore supplies about 78 mg of elemental magnesium. Products claiming more per 550 mg are drawing on a second, denser magnesium source as well, which is legitimate when declared. We explain that arithmetic in 22% vs 14% Magnesium Glycinate.
Check any label yourself. Our magnesium label calculator takes the compound weight and the elemental magnesium from any supplement label and tells you whether that percentage is possible for a single ingredient or only for a blend.
Who should choose magnesium glycinate?
- People who want magnesium for sleep support or relaxation
- Those with sensitive stomachs who can't tolerate citrate or oxide
- Anyone taking magnesium daily for general wellness — muscle function, bone health, energy metabolism
- People experiencing muscle cramps or tension
- Women looking for support during PMS or menstrual discomfort
What Is Magnesium Citrate?
Magnesium citrate is magnesium bound to citric acid. It is well absorbed, highly soluble, and widely available in India at a lower price point. However, it has an osmotic effect — it draws water into the intestines, which is why it's commonly used as a mild laxative.
This laxative property can be a benefit or a drawback, depending on your needs. If you struggle with occasional constipation, citrate serves a dual purpose. But if your digestion is already regular, higher doses may cause loose stools, cramping, or discomfort.
Who should choose magnesium citrate?
- People dealing with occasional constipation who want a gentle, natural option
- Those on a tighter budget who need a basic magnesium supplement
- People who need magnesium short-term rather than as a daily habit
Absorption: Which Form Does Your Body Use Better?
Both glycinate and citrate are well absorbed, and the honest answer is that the gap between them is small. Head-to-head human data comparing organic magnesium salts is thin, and fractional absorption of any form falls as the dose rises, which is why splitting a daily amount absorbs a greater share of it than one large dose.
Where glycinate does have an edge in daily practice:
- Chelation: The amino acid bond limits interaction with other compounds in the gut.
- No osmotic loss: Citrate pulls water into the intestine, which can flush unabsorbed magnesium out before your body has time to use it. Glycinate doesn't have this effect.
- Tolerability: You can take a full daily dose of glycinate without the bathroom consequences, which matters more over months than a few percentage points of absorption.
Side Effects: Glycinate vs Citrate
The biggest differentiator in day-to-day use is digestive tolerance.
Magnesium glycinate side effects
Very few. Glycinate is one of the gentlest magnesium forms available, and most people report no digestive issues at normal supplemental doses. Rare side effects may include mild nausea if taken on an empty stomach. Stay within the 350 mg/day supplemental upper limit for adults.
Magnesium citrate side effects
The main concern is its laxative effect. At doses above 200–300 mg elemental, many people experience loose stools, abdominal cramping, or diarrhoea. This makes it unsuitable for daily use at therapeutic doses for some individuals, particularly those with IBS or sensitive digestion.
Can You Take Both Together?
Yes — some people use magnesium glycinate daily for sleep and general wellness, and keep magnesium citrate on hand for occasional constipation. There's no interaction between the two forms. Just be mindful of your total elemental magnesium intake. The ICMR-NIN (2020) RDA for Indian adults is 440 mg/day for men and 370 mg/day for women counting food, and the upper limit for supplemental magnesium alone is 350 mg/day.
What About Magnesium Oxide, Threonate, and Taurate?
For completeness, here's how other popular forms compare:
| Form | Magnesium by weight | Best For | Drawback |
|---|---|---|---|
| Magnesium Oxide | 60.3% — the densest common form | Antacid use; adding magnesium density to a declared blend | Often laxative at repletion doses; no amino acid alongside it |
| Magnesium Threonate | 8.3% | Cognitive function, brain health | Expensive, limited availability in India |
| Magnesium Taurate | 8.9% | Cardiovascular support | Higher cost, fewer Indian brands |
| Magnesium Bisglycinate | 14.1% maximum | Same as glycinate (alternate name) | Often confused as a different form — it's the same |
On magnesium oxide: the widely repeated "only 4% absorbed" figure traces to a single 2001 urinary-excretion study that never tested glycinate at all, and whose authors concluded that inorganic salts can match organic ones depending on the preparation. In the one randomised trial comparing bisglycinate with oxide directly, absorption was similar in most participants and the chelate led only in people with impaired absorption. Oxide is a permitted magnesium source in India, the EU, Canada and the US. Its real weakness is tolerability at high doses, not legitimacy.
Note: Magnesium bisglycinate and magnesium glycinate are the same compound. "Bisglycinate" simply means each magnesium atom is bonded to two glycine molecules, which is the standard chelated form.
How to Choose the Right Magnesium for You
Ask yourself one question: what's your primary goal?
- Better sleep and relaxation → Magnesium glycinate
- Muscle cramps and recovery → Magnesium glycinate
- Daily wellness and deficiency correction → Magnesium glycinate
- Occasional constipation relief → Magnesium citrate
- Budget-friendly short-term use → Magnesium citrate
For most Indians looking for a daily magnesium supplement, glycinate is the better long-term choice for its gentle profile and the glycine that comes with it. HealthyHey offers two formats, both providing 121 mg of elemental magnesium per serving: Magnesium Glycinate 22% in one capsule a day, and 14% Fully Chelated across two capsules with bisglycinate as the only source. Both are veg capsules, NABL lab-tested, and manufactured under FSSAI licence in a GMP (TÜV India) certified facility.
Dosage Recommendations
| Form | Suggested Daily Dose | When to Take |
|---|---|---|
| Magnesium Glycinate | 200–350 mg elemental | Evening, with or without food |
| Magnesium Citrate | 200–300 mg elemental | Morning or as needed, with water |
Start with a lower dose and increase gradually, staying within the 350 mg/day supplemental upper limit. If you're taking other medications — especially blood pressure medications, antibiotics, or diuretics — consult your healthcare provider before starting any magnesium supplement.
Frequently Asked Questions
Is magnesium glycinate better than citrate?
For daily use, generally yes — glycinate causes fewer digestive side effects and brings the added calming benefit of glycine. On absorption alone the two are close. Citrate is useful specifically for constipation relief or as a budget option for short-term use.
Can magnesium citrate cause diarrhoea?
Yes. Magnesium citrate draws water into the intestines (osmotic effect), which can cause loose stools or diarrhoea, especially at doses above 300 mg elemental. This is its primary drawback for daily use.
Is magnesium bisglycinate the same as magnesium glycinate?
Yes, they are the same compound. "Bisglycinate" indicates two glycine molecules per magnesium atom, which is the standard chelated form sold as "magnesium glycinate."
Which magnesium is best for sleep in India?
Magnesium glycinate is the most studied form for sleep support because the glycine amino acid has independent calming properties. For more on this topic, read our guide on magnesium glycinate benefits and dosage.
How much magnesium do Indians need daily?
According to ICMR-NIN (2020), the RDA for magnesium is 370 mg/day for adult women and 440 mg/day for adult men, counting food as well as supplements. Many Indians fall short due to soil depletion and processed food diets.
