Magnesium is widely used to support relaxation and better sleep, but choosing the right form can be confusing. Two of the most popular options are magnesium glycinate and magnesium citrate. While both provide magnesium, they work differently in the body.

Why Magnesium Is Important for Sleep

Magnesium helps regulate:

• Nervous system activity
• Muscle relaxation
• Stress response

Low magnesium levels are often linked to restlessness, muscle tension, and difficulty falling asleep. Supplementing with the right form of magnesium may help support a calmer state before bedtime.

What Is Magnesium Glycinate?

Magnesium glycinate is magnesium bound to glycine, an amino acid known for its calming properties.

Key features:

• Highly absorbable
• Gentle on the stomach
• Less likely to cause digestive issues

Because of these traits, magnesium glycinate is commonly chosen for sleep support and relaxation.

---

What Is Magnesium Citrate?

Magnesium citrate is magnesium bound to citric acid.

Key features:

• Good absorption
• More likely to stimulate bowel movements
• Often used for constipation relief

While it can help increase magnesium levels, its digestive effects may not be ideal for nighttime use.

Which Is Better for Sleep?

For most people focused on sleep quality, magnesium glycinate is the better option.

Recommended Dosage for Sleep

Magnesium Glycinate

• 200–400 mg elemental magnesium
• Take 30–60 minutes before bed

Magnesium Citrate

• 200–300 mg elemental magnesium
• Best taken earlier in the day if sensitive digestion is an issue

Always check supplement labels for elemental magnesium, not total compound weight.

Side Effects and Tolerance

Both forms are generally safe when used as directed.

Possible side effects:

• Magnesium glycinate: mild drowsiness (desired at night)
• Magnesium citrate: loose stools or stomach discomfort

If digestive sensitivity is a concern, glycinate is usually better tolerated.

Who Should Choose Magnesium Citrate?

Magnesium citrate may be a better option if you:

• Experience occasional constipation
• Prefer a lower-cost magnesium supplement
• Take magnesium earlier in the day, not before bed

For pure sleep support, glycinate still tends to be the preferred choice.
