Improvement after a supplement is not the same as a comparative result
Start with the comparison. A before-and-after change alone cannot isolate the contribution of an ingredient.

- Combination, formula, or class studies do not isolate this ingredient or establish synergy.
Data coverage and detailed study classifications
Paper counts are separated by research topic below. One paper may contribute to multiple findings.
Analysis status: Public-ready
Ingredient analysis date:
How the grade was determined: B
The 56.0 evidence score includes 0 independent human studies and 0 clinical studies in the representative benefit area. The B tier remains conservative because of limited repetition across independent human clinical studies, too few clinical findings with an explicit effect direction.
The grade is based mainly on the research area with the most evidence. It does not mean the same result was found in other areas.

1 paper · 1 measured outcome
Direction counts are distinct papers within each row. Outcome contributions count endpoint results, so one paper may contribute more than once.
How to read research findings
How should I read research findings?
Research guidesNo clear difference and an uninterpretable result are different
A reported null comparison contains a result. An abstract without an interpretable comparison leaves a question unresolved.
Paper counts and study counts are different
Count original research separately from research that reanalyzes it. Publication volume is neither replication nor a quality rating.
Side effects and combination findings
Findings from this ingredient alone are shown separately from those involving another supplement or medication.
No reviewed caution rules are available yet. Reported caution findings are shown below.
Review 5 combination findings and 0 findings that outperformed an ingredient alone.
Findings to review with care
Side effects reported for the ingredient alone are separated from findings involving another supplement or medication.
Side effects reported with this ingredient alone
Symptoms or adverse events reported in studies without another active ingredient.
diarrhea leading to study discontinuation (tolerability)1 papers
In the randomized trial, the magnesium oxide group had a higher dropout rate than control (27% vs 17%), primarily due to diarrhea.Human studies · Randomized controlled trialReported improvements with combinations
Combination findings are grouped by how the study compared them. This is not a recommendation to combine ingredients.
Combinations with reported improvement
The combination showed improvement, but each ingredient's contribution is unclear.
비타민 B6In subjects with severe/extremely severe stress, the combination of magnesium and vitamin B6 resulted in a 24% greater improvement compared to magnesium alone (p=0.0203).
비타민 DCo-supplementation with Vitamin D and Magnesium resulted in significant improvements in behavioral function and mental health scores compared to placebo.
MelatoninCombined melatonin and magnesium supplementation was more effective in improving serum levels of insulin compared to baseline.
CholineCo-supplementation of choline and magnesium was more effective in improving inflammation and endothelial dysfunction than either alone.
아연Co-supplementation with magnesium oxide and zinc sulfate resulted in significant improvements in glycemic control, lipid profiles, and inflammatory markers compared to placebo.
