Aluminum is all around us—hidden in tap water, processed foods, cookware, cosmetics, medications, and even the air we breathe. While the scientific community continues to debate the full extent of its toxicity, decades of research show one undeniable fact: aluminum accumulates in the body and affects the brain.

For more than 50 years, studies have shown that aluminum exposure contributes to the formation of neurofibrillary tangles—the same twisted proteins found in the brains of people with Alzheimer’s disease. That’s because aluminum can enter the bloodstream through ingestion, inhalation, or skin absorption and bypass the body’s natural barriers, traveling straight into sensitive tissues like the brain, heart, and bones.

Although the digestive system removes most aluminum, even small retained amounts accumulate over time, especially in tissues with slow cell turnover.

Why Aluminum Toxicity Is a Concern

Research suggests aluminum buildup may play a role in:

• Alzheimer’s disease

• Parkinson’s

• Multiple sclerosis

• Chronic fatigue syndrome

• Autoimmune conditions

• Learning and developmental challenges

Because Alzheimer’s has no cure, scientists continue searching for ways to reduce risk and slow progression. Surprisingly, one simple solution has shown promise: silica-rich mineral water.

Silica Water: A Natural Way to Remove Aluminum

Silica, a naturally occurring mineral in certain types of mineral water, helps block aluminum absorption and encourages the body to excrete stored aluminum through urine.

Just 10 mg of silica per day has been shown to:
✔ Reduce aluminum uptake
✔ Increase aluminum elimination
✔ Protect against aluminum-related neurological effects

The Study That Got Global Attention

Professor Christopher Exley of Keele University conducted a small but eye-opening study involving 15 Alzheimer’s patients. Participants drank 1 liter of silica-rich water (brand: Spritzer, 35 mg/L) daily for 13 weeks.

Results after 3 months:

• Aluminum levels in urine dropped by up to 70%

• Cognitive decline stabilized

• Three patients showed noticeable improvements

Exley concluded that silica-rich water not only removes aluminum from the body but may also support cognitive health in those already affected by dementia.

Silica-Rich Waters You Can Buy

If “Spritzer” isn’t available, these common brands offer similar benefits:

• FIJI Water – ~45 mg/L

• Volvic – ~20 mg/L

Aim for at least 10–30 mg/L for aluminum detox benefits.

Quick Facts About Silica

• Silica = silicon dioxide, a natural mineral

• Not to be confused with silicone, a synthetic material

• Found naturally in water, plants, soil

• Supports collagen formation and joint health

• Beneficial for skin, hair, and nails

Turmeric for Additional Brain Protection

Curcumin—the active compound in turmeric—has been shown to:

• Reduce oxidative stress from aluminum exposure

• Decrease beta-amyloid plaque buildup

• Calm inflammation in the brain

• Improve memory and mood

Try adding 1 teaspoon of turmeric to a glass of silica-rich mineral water, or enjoy calming golden milk in the evening.

Bottom Line

Aluminum exposure is nearly impossible to avoid—but the body can eliminate stored aluminum when given the right tools. Silica-rich mineral water and anti-inflammatory herbs like turmeric offer a simple, natural way to support brain health and reduce toxin buildup.
