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 |
|---|---|---|
| Bound to | Glycine (amino acid) | Citric acid |
| Elemental Mg per dose | ~14% by weight | ~16% by weight |
| Bioavailability | High (chelated form) | Moderate–High |
| 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. This bond does two things: it dramatically improves absorption (chelated minerals pass through the gut lining more efficiently) 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.
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 has decent bioavailability and is 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 compared to cheaper forms like magnesium oxide (which has only ~4% bioavailability). However, magnesium glycinate has an edge for two reasons:
- Chelation: The amino acid bond protects the magnesium from interacting with other compounds in the gut, allowing more of it to reach your bloodstream intact.
- 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.
In practical terms, you’re likely to retain more magnesium per capsule with the glycinate form — which matters when you’re supplementing daily to correct a deficiency or maintain optimal levels.
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. Most people report no digestive issues even at higher doses (400–500 mg elemental). Rare side effects may include mild nausea if taken on an empty stomach.
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 RDA for Indian adults is 310–420 mg/day depending on age and gender (ICMR-NIN 2020).
What About Magnesium Oxide, Threonate, and Taurate?
For completeness, here’s how other popular forms compare:
| Form | Bioavailability | Best For | Drawback |
|---|---|---|---|
| Magnesium Oxide | Low (~4%) | Budget option, heartburn relief | Poor absorption, strong laxative effect |
| Magnesium Threonate | Moderate | Cognitive function, brain health | Expensive, limited availability in India |
| Magnesium Taurate | Moderate–High | Cardiovascular support | Higher cost, fewer Indian brands |
| Magnesium Bisglycinate | High | Same as glycinate (alternate name) | Often confused as a different form — it’s the same |
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 due to its superior absorption and gentle profile.

Dosage Recommendations
| Form | Suggested Daily Dose | When to Take |
|---|---|---|
| Magnesium Glycinate | 200–400 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. If you’re taking other medications — especially blood pressure medicines, antibiotics, or diuretics — consult your healthcare provider before starting any magnesium supplement.
Frequently Asked Questions
Is magnesium glycinate better than citrate?
For daily use, yes — glycinate offers better absorption, fewer digestive side effects, and the added calming benefit of glycine. 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 widely considered the best 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 310–340 mg/day for adult women and 370–420 mg/day for adult men. Many Indians fall short due to soil depletion and processed food diets.
