Metals
Metals
Heavy metals influence microbial pathogenicity in two ways: they can be toxic to microbes by disrupting cellular functions and inducing oxidative stress, and they can be exploited by pathogens to enhance survival, resist treatment, and evade immunity. Understanding metal–microbe interactions supports better antimicrobial and public health strategies.

Microbes
Microbes are microscopic organisms living in and on the human body, shaping health through digestion, vitamin production, and immune protection. When microbial balance is disrupted, disease can occur. This guide explains key microbe types—bacteria, viruses, fungi, protozoa, and archaea—plus major pathogenic and beneficial examples.

What was reviewed?
This article is a narrative review that synthesized what is known about magnesium’s roles in human physiology and disease, spanning basic mechanisms (enzyme activity, ATP-dependent energy production, ion-channel regulation, and cellular signaling) and clinical relevance across cardiometabolic, musculoskeletal, neurologic, and mental health outcomes. It also summarized dietary sources, factors that can reduce bioavailability, and clinical consequences of deficiency or insufficiency, with the goal of helping clinicians connect magnesium status to common chronic disease patterns rather than treating it as an isolated lab value.
Who was reviewed?
Because this was a review and not a single clinical study, it did not enroll one defined cohort; instead, it summarized findings from previously published human observational studies, clinical trials, and systematic reviews/meta-analyses across multiple populations. The literature it pulled from included adults with hypertension and cardiovascular disease risk, people with type 2 diabetes or insulin resistance, postmenopausal women and others at risk for osteoporosis, and groups studied for migraines, asthma, mental health symptoms, and aging-related outcomes, alongside supportive mechanistic and preclinical evidence where relevant.
What were the most important findings?
The core finding is that suboptimal magnesium status aligns with a recognizable, multi-system risk profile that clinicians see often: higher cardiometabolic risk, worse glucose handling, greater inflammatory tone, and increased neuromuscular irritability. Mechanistically, magnesium supports endothelial nitric oxide signaling and acts as a functional calcium antagonist in vascular smooth muscle, so deficiency plausibly pushes vasoconstriction and blood-pressure elevation while also destabilizing cardiac electrical activity. The review also emphasized a consistent inverse association between magnesium intake and type 2 diabetes risk, linking low magnesium to insulin resistance and impaired glucose metabolism, and it connected adequate magnesium to healthier bone mineralization and reduced osteoporosis risk.
What are the greatest implications of this review?
Clinically, this review supports treating magnesium as a high-leverage, low-cost modifier of chronic disease pathways rather than a niche electrolyte issue. It implies that patients with clustered problems—hypertension, insulin resistance, migraines, muscle cramps, fatigue, low mood, or age-related frailty—may benefit from a deliberate magnesium assessment and a food-first repletion strategy, with supplementation considered when intake is low or risk is high. For microbiome-informed care, the review reinforces that gut conditions and intestinal chemistry can shape magnesium bioavailability, so improving diet quality and gut function may indirectly improve magnesium status and downstream inflammatory-metabolic outcomes.
Magnesium (Mg)
Magnesium (Mg) is a vital metal that not only supports critical cellular functions in both humans and microbes but also plays a significant role in shaping microbial pathogenesis. By regulating microbial growth, virulence factor expression, and competition for nutrients, magnesium directly influences infection outcomes. Understanding how magnesium interacts with microbial communities and the host immune system provides novel insights into therapeutic strategies that modulate microbial behavior, potentially improving infection management and microbiome health.
