Why Magnesium Glycinate Is a Top Choice
If you take blood pressure medications, magnesium glycinate is one of the safest and most effective magnesium forms. It’s well absorbed, gentle on the stomach, and less likely to cause diarrhea than citrate or oxide forms.
Unlike other types, glycinate is chelated with the amino acid glycine, which not only boosts bioavailability but also helps calm the nervous system. That matters when managing hypertension, since both sleep and stress affect blood pressure.
Common Benefits of Magnesium Glycinate
- Supports healthy sleep and mood
- Helps regulate muscle and nerve function
- Plays a role in blood vessel relaxation
According to a 2021 systematic review, magnesium supplementation may reduce systolic blood pressure by 2–5 mmHg, particularly in magnesium-deficient people.
Still, the form and timing of magnesium matter. Let’s compare the top brands.

Dosage, Safety, and Medication Timing
Even the best magnesium glycinate brand can cause problems if used incorrectly, especially when combined with blood pressure medications.
Dosage Guidelines
- General recommendation: No more than 350 mg/day of elemental magnesium from supplements, unless advised by a physician
- Check the elemental magnesium amount, not just the total compound weight
Taking too much magnesium can lead to:
- Diarrhea (especially with citrate or oxide)
- Low blood pressure (especially if combined with antihypertensives)
- Drug absorption issues
For example, combining magnesium with metformin or diuretics can cause gastrointestinal symptoms like diarrhea.
Avoiding Drug Interactions
To reduce interaction risk:
- Take magnesium at least 2 hours apart from blood pressure meds like amlodipine, diltiazem, or ACE inhibitors
- Don’t exceed daily intake unless monitored
- Monitor for symptoms like dizziness or fatigue, which may suggest blood pressure has dropped too low

Third-Party Certification Matters

Look for these certifications on your magnesium glycinate label:
- ConsumerLab: Tests for label accuracy and contaminants
- USP Verified: Confirms identity, strength, purity, and dissolution
- NSF Certified: Verifies quality and is required for many athletes
