Micronutrient evidence brief
Magnesium is an essential mineral involved in muscle, nerve, and energy metabolism. Claims usually center on cramps, sleep, stress, blood pressure, and deficiency correction.
Important for normal muscle, nerve, and sleep-related physiology; supplementation is most useful when intake or status is low.
Insomnia review: older-adult sleep evidence ranges from possible benefit to null; quality remains low.
Use food-first intake review and avoid high supplemental doses that cause gastrointestinal issues.
Sleep, cramps, testosterone, and performance claims need separate evidence; this is not a blanket ergogenic rating.
Source Drawer
The score reflects evidence that the supplement does its stated job. Some jobs are direct, such as strength, endurance, or recovery; others are indirect, such as sleep, mood, appetite, or health support. A real effect can still receive a cautious practical rating when dose, safety, product quality, or audience fit remain uncertain.
Send the disputed claim, source link, and why it changes the practical verdict. Corrections that materially affect the claim, dose, caveat, or rating are prioritized.
