In recent decades, human exposure to aluminium (Al) has increased significantly due to its widespread use in food processing, consumer products, pharmaceuticals, and industrial applications. Although aluminium is one of the most abundant elements in the Earth’s crust, its bioavailability in daily life has risen due to modern environmental and technological factors.
This growing exposure has raised scientific interest in understanding how the body interacts with aluminium, and how certain nutrients (such as silicon), may influence its metabolism and elimination.
Aluminium is present in a wide range of everyday sources, including:
While intake varies depending on geography and lifestyle, studies suggest that chronic low-level exposure is common in modern populations.
FACT: Currently, our intake is approximately 30 mg per day, and by 2050, it's expected to skyrocket to 100 mg. Remarkably, back in 1950, we consumed just 1 mg daily.
Aluminum is not recognized as having any essential biological function in humans. Upon exposure:
Furthermore, trace amounts of aluminium have been detected in:
Most absorbed aluminium is excreted via the kidneys; however, retention may occur depending on exposure levels and individual physiological factors.
Because aluminium accumulation can be difficult to assess directly, urinary excretion is commonly used as an indirect biomarker of exposure.
Research has explored potential associations between aluminium exposure and various neurological and systemic health outcomes. Notable studies, including those conducted by Professor Christopher Exley (2006; 2013; 2017) and others, have reported:
While these findings contribute to ongoing scientific discussion and despite decades of evidence regarding the neurotoxic effects of aluminium, it is important to emphasize that:
The relationship between aluminium exposure and specific diseases remains under active investigation
Current evidence does not establish definitive causality between aluminium and these health outcomes.
Regulatory authorities are actively assessing safe exposure levels
Moreover, industrial stakeholders have characterized aluminium as “safe,” notwithstanding the existing scientific evidence. It is imperative to urgently reframe the perception of aluminium as a persistent environmental toxin.
Silicon has attracted attention due to its potential interaction with aluminium in biological systems.
Scientific evidence suggests that bioavailable forms of silicon, such as orthosilicic acid (OSA) and monomethylsilanetriol (MMST), may:
This interaction represents a physiological and non-invasive mechanism, distinct from pharmaceutical chelation approaches.
Several studies have investigated this relationship:
These findings support the hypothesis that silicon may contribute to maintaining aluminium balance in the body, although further research is required to fully elucidate its long-term implications.
Given the widespread presence of aluminium in the environment, nutritional strategies may play a role in supporting the body’s natural processes.
Silicon-based supplementation can be considered as part of a broader approach that includes:
Importantly, food supplements are intended to complement (not replace) healthy lifestyle practices.
The increasing presence of aluminium in modern life has led to growing scientific interest in how the body manages exposure to this element. While research continues to evolve, current evidence suggests that bioavailable silicon may play a supportive role in aluminium metabolism and excretion.
Innovative silicon forms such as MMST represent a science-driven approach to delivering silicon in a stable and bioavailable format, aligned with modern nutraceutical standards.
