Buying Guide: What to Look for in a Magnesium Glycinate Supplement
Choosing the right magnesium glycinate supplement goes beyond just comparing prices or brand names. We evaluated five products based on criteria that matter most for effectiveness, purity, and value. Here are the key factors we considered.
1. Form and Bioavailability
All the products in this review use magnesium bisglycinate (also listed as magnesium glycinate), which is chelated to the amino acid glycine. This form is known for superior absorption and being gentle on the digestive system. Some products, like the Magnesium Bisglycinate Chelated Supplement -180 from BioSchwartz, specifically highlight the use of Albion TRAACS, a patented chelated mineral that has been widely studied for bioavailability. When scanning labels, look for “magnesium bisglycinate” or “magnesium glycinate” as the primary source, and avoid forms like magnesium oxide if you want minimal laxative effects.
2. Serving Size and Dosage Flexibility
Magnesium needs vary by individual, so a supplement that offers adjustable dosing is a plus. For instance, Nutricost Magnesium Glycinate Capsules provide 210 mg of magnesium per three-capsule serving, allowing you to take one or two capsules for a lower dose. In contrast, Nature Made Magnesium Glycinate 200 mg per serving requires two capsules per serving. If you prefer a once-daily dose, look for products with higher mg per capsule. Also, consider the bottle size: the 360-capsule option from Nutricost offers a longer supply for consistent use.
3. Quality Assurance and Third-Party Verification
Reputable brands invest in manufacturing standards and independent verification. Both Nutricost products are made in NSF-certified GMP compliant facilities and undergo third-party evaluation for potency and purity. Similarly, BioSchwartz follows strict cGMP guidelines and uses globally sourced ingredients. Thorne is known for its high-quality standards and is often recommended by healthcare professionals. When selecting a supplement, check for certifications like NSF, GMP, or third-party seals that confirm the product meets label claims. Avoid brands that do not disclose their quality processes.
