Based on multiple meta-analyses showing dose-response relationship for occupational crystalline silica exposure and respiratory disease risk. This represents HARMFUL effects from inhalational exposure, not benefits from dietary supplementation. Studies support reducing exposure limits from 0.1 to 0.05 mg/m³. No studies provided support beneficial effects of silica supplementation for hair, nails, skin, or bone health.
