POSSIBLY EFFECTIVE

• Osteoporosis. Higher dietary intakes of silicon in males and premenopausal females seem to be associated with higher bone mineral density (BMD), but it is unclear whether silicon supplements reduce the risk of osteoporosis. Details: Males and premenopausal females who have dietary intakes of silicon of at least 40 mg daily seem to have higher BMD than those with lower intakes. This could reduce the risk of osteoporosis (10470,12425). However, it is unclear if silicon supplements can reduce the risk for osteoporosis. Silicon intake has also been evaluated in postmenopausal females. Clinical and population-based research suggests that higher silicon intake does not seem to benefit postmenopausal females in general, although it may benefit those on hormone replacement therapy (10470,12425,75118,92135). Bone loss in postmenopausal females is primarily due to bone resorption. Silicon seems to affect only bone formation (12425).

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Aging skin. It is unclear if oral silicon is beneficial in patients with aging skin. Details: A small preliminary clinical study in healthy volunteers aged 40-60 years shows that taking a specific product (Exsynutriment by Biotec) containing organic silicon 600 mg in hydrolyzed marine collagen once daily, 15 minutes before breakfast, for 90 days improves skin firmness, hydration, and texture, but not wrinkles, brightness, or softness, when compared with placebo (100837).
• Alzheimer disease. Although there has been interest in using oral silicon for Alzheimer disease, there is insufficient reliable information about the clinical effects of silicon for this condition.
• Androgenic alopecia. Although there has been interest in using oral silicon for androgenic alopecia, there is insufficient reliable information about the clinical effects of silicon for this condition.
• Cardiovascular disease (CVD). Although there has been interest in using oral silicon for CVD, there is insufficient reliable information about the clinical effects of silicon for this condition.
• Dental peri-implantitis. It is unclear if oral silicon is beneficial in patients with peri-implantitis. Details: A small, preliminary clinical study in patients aged 18-75 with peri-implantitis shows that a specific choline-stabilized orthosilicic acid product (BioSil, Bio Minerals NV) containing silicon 5 mg and choline 100 mg, taken twice daily for 12 months, does not improve markers of inflammation and periodontal disease (i.e. probing pocket depth, bleeding on probing) when compared with placebo (110028). However, this study may not have been adequately powered to detect a difference between groups. More evidence is needed to rate silicon for these uses.

LIKELY SAFE ...when used orally and appropriately in amounts commonly found in foods (7135,10470,92135). It is estimated that the average dietary intake of silicon is 20-50 mg daily (110029); however, there is currently no established recommended dietary allowance or tolerable upper intake level for silicon (7135,92136,95009,110029).

PREGNANCY AND LACTATION: LIKELY SAFE
when used orally in amounts commonly found in foods (7135,10470). It is estimated that the average dietary intake of silicon is 20-50 mg daily (110029). There is insufficient reliable information available about the safety of silicon when used in larger, medicinal amounts; avoid using.

General ...Orally, silicon in the amounts found in food and water is not associated with adverse effects.
Serious Adverse Effects (Rare):
Inhaled: Crystalline silicon dioxide in the form of quartz dust found in industrial and occupational settings is associated with an increased risk of diseases such as silicosis, tuberculosis, chronic bronchitis, chronic obstructive pulmonary disease (COPD), lung cancer, glomerulonephritis, vasculitis, and rheumatoid arthritis.

Cardiovascular ...Case control studies have shown that occupational exposure to silicon dioxide-containing compounds may cause vasculitis (75114). Patients with occupational pulmonary silicosis may develop microscopic polyangiitis (inflammation of the blood vessels in the nose, sinuses, throat, lungs, and kidneys, also known as Wegener's granulomatosis).

Dermatologic ...Occupational silica exposure may be a risk factor for scleroderma, particularly in males (75099).

Genitourinary ...Limited reports in humans indicate that long-term use of large amounts of antacids containing magnesium trisilicate may be associated with urolithiasis and silicon-containing stones (11760,11861,75075,75103). However, fewer than 30 cases associated with antacids containing silicates have been reported, despite these products being commercially available since the 1930s. Although exceptionally rare, silicon dioxide kidney stones can also occur without magnesium trisilicate ingestion (11556). Their formation is caused by an acidic urinary pH. In at least one case, urine alkalinization resulted in resolution of the symptoms (75075).
Case-control studies have shown that occupational exposure to silicon dioxide is related to antineutrophil cytoplasmic antibody (ANCA)-associated glomerulonephritis (75114). High silicon levels in patients undergoing chronic hemodialysis have been associated with nephropathy (75089).

Hepatic ...High silicon levels in patients undergoing chronic hemodialysis have been associated with liver disease (75089).

Musculoskeletal ...High silicon levels in patients undergoing chronic hemodialysis have been associated with bone disease (75089). A meta-analysis suggests that the risk of rheumatoid arthritis is elevated with occupational exposure to silicon dioxide (75078).

Neurologic/CNS ...High silicon levels in patients undergoing chronic hemodialysis have been associated with neuropathy (75089).

Pulmonary/Respiratory ...Occupational exposure to crystalline silicon dioxide dust is associated with an increased risk of pulmonary diseases such as silicosis, tuberculosis, chronic bronchitis, chronic obstructive pulmonary disease (COPD), and lung cancer (75076,75081,75084,75114). Patients with occupational pulmonary silicosis may develop microscopic polyangiitis (inflammation of the blood vessels in the nose, sinuses, throat, lungs, and kidneys, also known as Wegener's granulomatosis). Meta-analyses suggest that occupational exposure to silicon dioxide increases the risk of lung cancer (75085,75095,75115). An analysis of 19 studies shows that lung cancer risk is approximately 2 times higher for those with silicosis (75115). It is not clear whether silicon dioxide is carcinogenic in the absence of silicosis (75083).
