Silicon and its derivatives—especially silicic acid—have been studied for potential neuroprotective effects, including in the context of Alzheimer’s disease (AD).
-Silicon is a trace element involved in bone health, connective tissue, and possibly cognitive function.
-It is most bioavailable in the form of orthosilicic acid (OSA), a soluble and absorbable form often found in drinking water or supplements
-Silicon binds aluminum, forming hydroxyaluminosilicates that are poorly absorbed by the gut and are more easily excreted.
-Silicic acid may protect neurons from oxidative and inflammatory stress, mechanisms relevant to AD.
