Compare Magnesium Glycinate Products by Cost Per Day Magnesium glycinate appears in more of our stacks than any other single product — here's how it compares on cost per day. The evidence · Magnesium Glycinate What the published reviews of Magnesium Glycinate concluded Clinical trial on the effects of oral magnesium supplementation in stable-phase COPD patients. · Aging clinical and experimental research , 2022 “Although the established minimum sample size was not reached, our results suggests that oral magnesium supplementation may have a potential anti-inflammatory role. On the other hand, it does not seem to substantially influence lung function, physical performance, and quality of life in COPD patients.” “Although the established minimum sample size was not reached, our results suggests that oral magnesium supplementation may have a potential anti-inflammatory role. On the other hand, it does not seem to substantially influence lung function, physical performance, and quality of life in COPD patients.” Low-volume oral colonoscopy bowel preparation: sodium phosphate and magnesium citrate. · Gastrointestinal endoscopy , 2002 “When taken entirely the day before colonoscopy, Mg is superior to NaP. Taking NaP the evening before and morning of colonoscopy improved bowel cleansing compared with taking it entirely the day before.” “When taken entirely the day before colonoscopy, Mg is superior to NaP. Taking NaP the evening before and morning of colonoscopy improved bowel cleansing compared with taking it entirely the day before.” Superiority of magnesium and vitamin B6 over magnesium alone on severe stress in healthy adults with low magnesemia: A randomized, single-blind clinical trial. · PloS one , 2018 “These findings suggest oral Mg supplementation alleviated stress in healthy adults with low magnesemia and the addition of vitamin B6 to Mg was not superior to Mg supplementation alone.” “These findings suggest oral Mg supplementation alleviated stress in healthy adults with low magnesemia and the addition of vitamin B6 to Mg was not superior to Mg supplementation alone.” The Association of Gut Microbiota With TRPM7 Genotype, Colorectal Polyps, and Magnesium. · The Journal of nutrition , 2025 “Our findings indicate that the gut microbiota in stool, rectal swab, and mucosa are associated with risk of metachronous colorectal polyps, and diet changes could modify the abundance of TRPM7-related microbes.” “Our findings indicate that the gut microbiota in stool, rectal swab, and mucosa are associated with risk of metachronous colorectal polyps, and diet changes could modify the abundance of TRPM7-related microbes.” Method: PubMed searched in humans for randomised trials with Magnesium Glycinate in the title; these 4 of the 31 that qualified are shown with the authors’ own conclusion quoted rather than summarised. What it cannot tell you: whether Magnesium Glycinate will work for you — each of these reports an average across trials published 2002–2025, and null findings are shown here as readily as positive ones. Every comparison uses clinical evidence from PubMed systematic reviews, product label data from the NIH Dietary Supplement Label Database , and third-party certifications ( USP , NSF ). Products are ranked by cost per clinically-effective dose. See our methodology and editorial standards .
