Aluminum

Specialist

also al, plasma aluminum

What it isA ubiquitous metal with no biological role. Exposure comes from antiperspirants, antacids, processed food additives, certain cookware, and historically from dialysis water. Healthy kidneys excrete it; chronic kidney disease impairs clearance.

DoesAt elevated levels, deposits in bone and brain where it interferes with neuronal and osteoblast.

GoodLow plasma aluminum protects bone, nervous system, and red blood cell formation, particularly in kidney disease.

BadAccumulated aluminum causes dialysis-associated dementia, osteomalacia, and microcytic anemia. Routine exposure in healthy people is not strongly linked to dementia despite popular concern, but high levels in dialysis or premature infants are clearly harmful.

Standard

<10 µg/L plasma.

Optimal

0–7 µg/L (lower is good)

Modifiers

Kidney dominates clearance; chronic antacid use raises absorption.

How to optimize

Lifestyle: Aluminum-free antiperspirants and cookware for those with kidney disease or measured elevation; limit aluminum-containing antacids.
Diet: Limit highly processed foods with aluminum-containing additives (some baking powders, processed cheese).
Supplements: Silicic acid (silica) modestly accelerates urinary aluminum excretion; magnesium adequacy supports kidney clearance.
Peptides: —
Drugs: Deferoxamine chelation reserved for high-level toxicity in dialysis patients.
