Magnesium Glycinate vs Citrate

Magnesium is essential for energy production and muscle relaxation, but not all supplements are the same. Glycinate and citrate, two common forms, each have unique benefits and drawbacks. We'll explore their differences in absorption, digestion, and health benefits. By the end, you'll know which magnesium supplement suits your needs best.

Absorption and bioavailability: How do glycinate and citrate measure up?

When it comes to supplements, it's not just about what you take, but how well your body can use it. Bioavailability, the extent to which a nutrient can be absorbed and used by your body, is a key factor in supplement efficacy.

So how do magnesium glycinate and citrate compare? There is only limited data comparing glycinate to citrate bioavailability, with one study suggesting that citrate may slightly edge on total bioavailability in in vitro settings, but in vivo bioavailability may be different.

Primary uses and benefits: Which form aligns with your health goals?

Choosing between magnesium glycinate and citrate often comes down to your specific health objectives. Let's explore the primary uses and benefits of each form to help you make an informed decision.

Magnesium glycinate: The sleep and stress supporter

• Sleep quality improvement: Glycine, the amino acid bound to magnesium in this form, has calming effects on the brain. This can lead to improved sleep quality and may help address insomnia.
• Muscle tension and pain: Both citrate and glycinate may help alleviate muscle tension and reduce occasional muscle cramps and other causes of pain.

Magnesium citrate: The heart, muscle and bone health ally

• Blood pressure regulation: What role does citrate play in cardiovascular health? While more research is needed, magnesium citrate may help support healthy blood pressure levels as part of a balanced diet and lifestyle.

Dosage recommendations and potential side effects

Understanding proper dosage and being aware of potential side effects is crucial when considering magnesium supplementation. Let's explore these important aspects:

Recommended dosage:

• The Recommended Dietary Allowance (RDA) for magnesium varies by age and gender:
  • Adult men: 400-420 mg per day
  • Adult women: 310-320 mg per day (350-360 mg during pregnancy)

Potential side effects:

While magnesium is generally safe when taken as directed, be aware of these potential side effects:

• Nausea
• Drowsiness
• Mild digestive discomfort
• Diarrhea
• Abdominal cramping
• Nausea

Important note: Excessive magnesium intake can lead to magnesium toxicity, especially in people with kidney problems. Symptoms may include low blood pressure, confusion, and irregular heartbeat. If you experience these symptoms, seek medical attention immediately.
