Overdosage and Toxicity Symptoms
If silica supplements that are much higher than the tolerable upper limit are taken, then they can cause the following toxicity symptoms:
- Skin rash
- Stomach irritation
People experiencing any of the above toxicity symptoms should discontinue their silica supplements and seek medical advice.
Overdosage and toxicity is more likely to occur from taking too many supplements, whereas dietary intake of silica is highly unlikely to cause overdosage.
Silicosis is a health condition that occurs when silica dust particles are inhaled. It causes an inflammation and scarring of the lungs, which causes fibrosis of the lungs. The silica dust enters the lungs and irritates them continuously and reduces the capacity of the lung, as silica does not dissolve over time. This condition can be a health hazard for people working with sandblasting equipment and who do not wear protective head gear.
