Magnesium Glycinate, 180 Vegetarian Capsules

Supplement name: Metabolic Maintenance, Magnesium Glycinate, 180 Vegetarian Capsules Supplement scores: 7 Introduction & context: This product delivers magnesium glycinate, a chelated form known for superior bioavailability compared to oxide or citrate. Each capsule contains 135 mg of elemental magnesium, priced around $0.20 per serving. Third-party testing by NSF ensures purity, but batch-specific contaminant data is unavailable. Evidence summary: Human trials favor magnesium glycinate for reducing mild anxiety and improving sleep quality, with studies using doses of 200–420 mg/day. However, this product’s 135 mg dose falls short of studied efficacy thresholds. A 2017 meta-analysis (n=11,366) highlighted magnesium’s role in lowering blood pressure, but benefits varied by form and dosage. Formulation & quality analysis: The glycinate chelate enhances absorption, minimizing gastrointestinal side effects. Vegetarian capsules and minimal excipients suit most diets, though the absence of bioavailability enhancers like vitamin D3 is notable. Safety & interactions: Generally safe, though high doses may cause diarrhea. Caution with kidney disease; interacts with certain antibiotics. Personal experience after taking the product: No significant changes in sleep or anxiety over 4 weeks. Value & practicality: Cost-effective per capsule, but underdosed relative to clinical research. Better options exist at higher doses. Overall verdict + score: Moderate efficacy due to suboptimal dosing. Suitable for those sensitive to higher magnesium amounts, but not ideal for therapeutic targets. 7/10 Who it's for: Individuals seeking mild magnesium supplementation or with digestive sensitivities. I’d consider higher-dose alternatives or combining with dietary sources.

This is my favorite magnesium. The ingredients are clean, and the amount is a good value. Magnesium is important for so many things from heart to bones. This brand is the most gentle on my stomach.

My husband asked for this to help him relax and to sleep better. I took it as well. But I don’t like these things cos I have a sensitive body. It does make body feel after a while. My husband didn’t believe me and took it everyday. After a while he felt body weaker and having even higher blood pressure. I guess it helped to relax and sleep better for some people, but after relaxing, it probably makes the body feel worse after.
