Magnesium Glycinate vs Magnesium Citrate
Which is Better: Magnesium Glycinate or Citrate?
Magnesium is an essential mineral responsible for over 300 biochemical reactions in the body, including muscle function, nerve signaling, and energy production. Two of the most popular forms of magnesium supplements are Magnesium Glycinate and Magnesium Citrate. But which one is better for you? Let's explore their differences.
Comparison Table: Magnesium Glycinate vs. Magnesium Citrate
| Feature | Magnesium Glycinate | Magnesium Citrate |
|---|---|---|
| Absorption | Highly bioavailable, easily absorbed | Moderate absorption acts as a laxative |
| Digestive Effects | Gentle on the stomach | May cause loose stools or diarrhea |
| Best For | Anxiety, sleep, muscle relaxation | Constipation, digestive health |
| Side Effects | Minimal side effects | May cause digestive discomfort |
Why is Magnesium Glycinate Better?
Magnesium Glycinate is a highly bioavailable form of magnesium, meaning it is easily absorbed by the body. It is bound to glycine, an amino acid that promotes relaxation and has calming effects.
- Better Absorption: Studies suggest that Magnesium Glycinate has superior absorption compared to other forms of magnesium (source).
- Gentle on the Stomach: Unlike Magnesium Citrate, it does not cause digestive discomfort or act as a laxative.
-
Supports Mental Health: Magnesium Glycinate is often recommended for anxiety, stress, and sleep disorders.
Which is the Best Form of Magnesium to Take?
The best form of magnesium depends on your health needs:
- For Relaxation & Sleep: Magnesium Glycinate is the best choice due to its calming effects.
- For Digestive Health: Magnesium Citrate acts as a natural laxative and helps with constipation.
-
For General Well-being: Both forms are beneficial, but Magnesium Glycinate is preferred for overall daily supplementation.
How Much Magnesium Do I Need?
The recommended daily allowance (RDA) for magnesium varies based on age, gender, and health conditions. Below are general guidelines:
- Men (19-30 years): 400 mg per day
- Women (19-30 years): 310 mg per day
- Men (31+ years): 420 mg per day
- Women (31+ years): 320 mg per day
-
Pregnant Women: 350-360 mg per day
These values are general recommendations. Always consult a healthcare provider before taking supplements.
