Magnesium Glycinate vs Citrate Comparison Table
| Feature | Magnesium Glycinate | Magnesium Citrate |
|---|---|---|
| Best for | Daily use, sensitive stomachs, nighttime routine | Digestion support, occasional constipation, general magnesium intake |
| Stomach tolerance | Usually gentler | More likely to loosen stools |
| Common reason people buy it | Calm evening routine and daily support | Digestive regularity and magnesium support |

| Best beginner choice | Yes, for most people | Good if digestion is the goal |
| Best iHerb product type | Glycinate or bisglycinate capsules | Citrate tablets or capsules |
What Is Magnesium Glycinate?
Magnesium glycinate is magnesium bound to glycine, an amino acid. It is often chosen by people who want a gentle form of magnesium that is easier to include in a daily routine.
Many buyers prefer magnesium glycinate because it is usually less likely to cause digestive discomfort compared with some other forms. This makes it a popular option for people who want magnesium for general wellness, muscle support, or an evening supplement routine.
However, magnesium glycinate is not a sleeping pill, anxiety treatment, or medical cure. It is simply a form of magnesium that many people find easier to tolerate.
Magnesium Glycinate Pros
- Usually gentle on the stomach
- Good for daily use
- Popular for nighttime routines
- Lower chance of laxative effect
- Often a good first magnesium choice
Magnesium Glycinate Cons
- Can cost more than citrate
- Some capsules may be large
- Some formulas may be mixed with other magnesium forms
- Not the best choice if your main goal is constipation support
What Is Magnesium Citrate?
Magnesium citrate is magnesium bound to citric acid. It is a common form of magnesium and is often used when people want both magnesium support and digestive regularity.
MedlinePlus states that magnesium citrate is used short-term for occasional constipation and works by retaining water with the stool, which can increase bowel movements and soften stool.
This is why magnesium citrate can be helpful for some people but uncomfortable for others. If your stomach is sensitive, or if you do not want a laxative-like effect, magnesium glycinate may be the better choice.
Magnesium Citrate Pros
- Common and easy to find
- Often more affordable
- Can support digestive regularity
- Available in many iHerb products
- Good option if constipation support is part of your goal
Magnesium Citrate Cons
- More likely to cause loose stools
- Not ideal for everyone before bed
- Can cause stomach discomfort in some people
- Should not be overused for constipation unless advised by a healthcare professional
Which Is Best: Magnesium Glycinate or Citrate?
The best choice depends on your goal.
For most people, magnesium glycinate is the best starting point because it is usually gentle and easy to use daily.
For digestion support, magnesium citrate may be the better choice because it is more likely to support bowel movements.
Here is the simple breakdown:
| Goal | Best Choice |
|---|---|
| Daily magnesium support | Magnesium glycinate |
| Sensitive stomach | Magnesium glycinate |
| Nighttime routine | Magnesium glycinate |
| Occasional constipation support | Magnesium citrate |
| Budget-friendly option | Magnesium citrate |
| Beginner-friendly choice | Magnesium glycinate |

How to Choose the Best Magnesium on iHerb
When choosing the best magnesium supplement on iHerb, do not look only at the price or star rating. The Supplement Facts label matters more.
1. Check the magnesium form
Look for the exact type of magnesium:
- Magnesium glycinate
- Magnesium bisglycinate
- Magnesium lysinate glycinate
- Magnesium citrate
Avoid choosing a product only because it says “magnesium complex.” A complex may include several forms, and some forms may be less suitable for your goal.
2. Check elemental magnesium
The important number is the amount of actual magnesium per serving. This may be listed as 100 mg, 133 mg, 200 mg, or another amount.
Do not confuse the weight of the compound with elemental magnesium.
3. Compare capsules per serving
One product may require one capsule. Another may require two, three, or four capsules. This affects convenience and cost per serving.
4. Think about your goal
Choose based on your reason for buying:
- For daily use: glycinate or bisglycinate
- For sensitive stomach: glycinate
- For digestion support: citrate
- For budget: citrate may be better
- For a simple beginner choice: glycinate
5. Read the warning label
The NIH notes that magnesium from dietary supplements and medications should not be consumed above the upper limit unless recommended by a healthcare provider. For adults, the upper limit from supplements and medications is 350 mg per day.
Magnesium supplements can also interact with certain medications, including antibiotics and bisphosphonates, so it is smart to check with a healthcare professional if you take medication.
Magnesium Glycinate vs Citrate: Which One Should You Buy?
For most readers, the best first choice is magnesium glycinate or magnesium bisglycinate.
It is usually better for:
- Daily magnesium support
- Sensitive stomachs
- Evening routines

Magnesium citrate is better if you specifically want:
- Digestive regularity support

The best overall choice for most iHerb shoppers is a glycinate-style supplement such as Doctor’s Best High Absorption Magnesium or California Gold Nutrition Magnesium Glycinate.
