# Consensus checked against original sources: Magnesium Forms, Sleep and Stress

Cutoff: 12 October 2026. Consensus supports discovery and checks of specific source aspects; it is not a primary study, a full-paper audit or a causal probability meter.

## Consensus describes a modest bisglycinate effect and1523mg glycine coingredient.
Selected original Methods confirm the studied bisglycinate salt supplies250mgMgand1523mgglycine daily; this is ligand exposure, not necessarily separately added freeglycine. Original Results show small primaryISI benefit,d=.2,p=.049,153baselineanalyzed and134completed. There is no ligand-matched control, objective sleep or established clinically important between-arm responder result. [Original PMID40918053](https://pubmed.ncbi.nlm.nih.gov/40918053/). Access: full_text_partial.

## Consensus reports equal globalPSQI improvements with citrate andplacebo but suggests deficient responders.
Original abstract confirms no supplement-specific globalPSQI effect. Low-status serum andCRP responses occur in selected baseline groups, yet they do not establish sleep responsiveness or a deficiency-only causal boundary. [Original PMID21199787](https://pubmed.ncbi.nlm.nih.gov/21199787/). Access: abstract_metadata.

## Provider emphasizes subjective improvements and low nutritional status in the older-adult trial.
Selected original Methods show dietaryMg<75%RDA andserumMg<0.95mmol/L; this does not prove every participant had clinical hypomagnesemia. Sample power usedrenin;46entered and43completed. Selected Results retain total-sleep-time null alongside positiveISI/log/hormone measures. [Original PMID23853635](https://pubmed.ncbi.nlm.nih.gov/23853635/). Access: full_text_partial.

## Provider mentions selected wearable and awakening benefits but understates prespecification limits.
Original body has null overallISI time×group(p=.39) and severalLSEQsleep subscales. Correction40567408 adds retrospective-registration and competing-interest disclosures, attached to the parent rather than counted as anotherstudy. Wearable scores are not directpolysomnographic architecture. [Original PMID39252819](https://pubmed.ncbi.nlm.nih.gov/39252819/). Access: full_text_partial.

## Consensus synthesis does not fully detail the newer threonate endpoint nulls.
Selected original body confirms prospective registration and allocation-guess assessment; sleep-related-impairment improves, while sleepdisturbance, restorative sleep andallring-derivedsleep outcomes are null. The severe subgroup is exploratory. Cognitive-age transformation is not observed brainrejuvenation. [Original PMID41601871](https://pubmed.ncbi.nlm.nih.gov/41601871/). Access: full_text_partial.

## Provider general sleep narrative could obscure trial-specific baseline comparability.
Selected original Results report baselineISI category imbalancep=.0001, with post-treatment between-group association also p=.0001. Without an adjusted change contrast this is a weaker causal anchor; selected Methods also impose a Mg/K-restricted diet. The two metabolic/renal followups share the same trial. [Original PMID39534260](https://pubmed.ncbi.nlm.nih.gov/39534260/). Access: full_text_partial.

## Consensus sometimes treats stress improvement withMg as isolated nutrient efficacy.
Original randomization comparesMg+B6toMg, with noMg-free arm. The overall primary comparison is null; severe-stress subgroup advantage concerns addedB6. Improvements within botharms do not identify Mgcausality. [Original PMID30562392](https://pubmed.ncbi.nlm.nih.gov/30562392/). Access: abstract_metadata.

## Provider correctly separates form absorption from direct sleepcomparisons.
Original body confirms serum-profile differences alongside null urinary contrasts and unequal elemental doses across formulations. These findings measure availability, not superiority ofglycinate/threonate for sleep. [Original PMID31330811](https://pubmed.ncbi.nlm.nih.gov/31330811/). Access: full_text_partial.

## Provider attributes plausibility to deficiency/neural models.
Original rat experiment shows longdeficiency sleep disruption and restoration onMg repletion. Its restricted nutritional/species context cannot establish a broad hypnotic effect inreplete adults. [Original PMID8232845](https://pubmed.ncbi.nlm.nih.gov/8232845/). Access: abstract_metadata.

## Provider discusses multiingredient contamination ofsleep results.
Original factorialPCOS trial reportsPSQI improvements inmelatonin andmelatonin+Mg groups, not a demonstratedMg-only advantage. Component attribution mustretainthe actualarms ratherthantransfer the combinedresult. [Original PMID34092248](https://pubmed.ncbi.nlm.nih.gov/34092248/). Access: abstract_metadata.

## Completeness of the provider formulation outline
The original2023 trial randomized109 postoperative breast-cancer patients and found no between-arm PSQI, mood or cognitive benefit. It supplies a relevant null formulation result omitted from the provider outline. Enrollment was for pain prevention, so it cannot be treated as a direct falsification of the registered primary-insomnia claim. Search omissions and limited coverage do not establish literature-wide absence. [Original PMID37520407](https://pubmed.ncbi.nlm.nih.gov/37520407/). Access: abstract_metadata.

## Methods
Consensus was used to identify literature and cross-check specific claims about design, endpoints, scope and research gaps. Those aspects were checked against original primary abstracts/status records and selected original Methods/Results passages. Consensus output was not treated as original full text. Provider search omissions are not evidence that a study does not exist. Source access and examination receipts are retained. Scite use or monthly unavailability is recorded per case; provider citation counts do not change causal grades.
