Silicon Drug Interactions, Uses, Effectiveness, Safety & More
What is this page for?
First and foremost: how Silicon interacts with medications. The heart of this page is the interaction list — every drug Silicon is known to interact with, and how serious each one is.
But these pages have grown well beyond that into a full monograph — what Silicon is, what people use it for and how strong the evidence is, its safety and side effects, and answers to the questions we’re asked most — written and reviewed by the clinical staff at HelloPharmacist. It’s educational information from our licensed clinical databases, not medical advice, and we don’t sell or endorse products. Our editorial policy

What Severity, Likelihood & Evidence Mean
Severity — How Serious It Can Be
- Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
- Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
- Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
- No known interaction. Checked against our sources with nothing documented — not the same as proven safety.
Likelihood — How Well It’s Documented
- Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
- Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
- Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
- Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

Silicon: Uses, Safety & Side Effects
Silicon is a trace mineral found in the body and in foods like oats, barley, and certain fruits and vegetables, and it is popular in supplements for hair, skin, nail, and bone health. Some small studies suggest possible benefits for skin and bone, but the overall evidence is limited and not strong. For most healthy people a balanced diet supplies enough silicon, so talk with a pharmacist or doctor before taking a supplement.

- Part used
- Silicon is a mineral element, not a plant part; supplements use silica, silicic acid, or stabilized orthosilicic acid
- Common forms
- Capsules, tablets, liquid drops (orthosilicic acid), powders; also found in horsetail and bamboo extracts and as silicon dioxide
- Hair, skin, and nail health
- Bone health and osteoporosis
- Joint and connective tissue support
- General 'beauty from within' support
Popular and traditional uses — not proof it works. See “Uses & effectiveness” below for the evidence.
Generally well tolerated from food and most supplements, but high-dose or long-term safety is not well studied.

Overview
Silicon is a natural element (atomic number 14) and one of the most common elements on Earth. In the body it is found in small amounts, especially in skin, hair, nails, bones, and other connective tissues, where it is considered a trace mineral.
We normally get silicon from the foods we eat. Good dietary sources include oats, barley, rice, whole grains, and some fruits and vegetables. Drinking water and certain beers also contain silicon.
As a supplement, silicon is sold in several forms, such as silica (a compound of silicon and oxygen), silicic acid (also called orthosilicic acid), and choline-stabilized orthosilicic acid (ch-OSA). People most often take it hoping to improve the look and strength of their hair, skin, and nails, and sometimes for bone health.
How it works
Silicon is thought to play a role in forming and maintaining connective tissue. It may help with the production and stability of collagen and other building blocks found in skin, hair, nails, cartilage, and bone.
For bone, researchers think silicon may help with how the body uses minerals like calcium and may support the cells that build bone. For skin and hair, the idea is that silicon supports collagen and structural proteins.
It is important to know that much of this is based on laboratory and animal research, and the exact way silicon works in people is not fully understood. The body absorbs orthosilicic acid more easily than some other forms, which is one reason stabilized forms are popular in supplements.
Does Silicon work?
How to read these evidence grades
Natural Medicines’ 7-point scale. We show each rating’s label word-for-word.
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.
Also studied for 5 conditions — evidence insufficient to rate
Insufficient Reliable Evidence To Rate Aging skin
It is unclear if oral silicon is beneficial in patients with aging skin.
Insufficient Reliable Evidence To Rate 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.
Insufficient Reliable Evidence To Rate 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.
Insufficient Reliable Evidence To Rate 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.
Insufficient Reliable Evidence To Rate Dental peri-implantitis
It is unclear if oral silicon is beneficial in patients with peri-implantitis.

Where Natural Medicines hasn’t rated a use, HelloPharmacist’s pharmacists may add their own reviewed rating and evidence (each such entry is labeled). This is educational information, not medical advice — talk with your pharmacist or doctor before starting, stopping, or changing a supplement.
Safety & precautions
Silicon from food is considered safe and is a normal part of a healthy diet. Supplements taken at typical doses are generally well tolerated by most healthy adults, but the long-term safety of higher doses has not been well studied.
People with kidney problems should be especially careful, since the kidneys clear silicon from the body, and damaged kidneys may not handle it well. Anyone with a chronic health condition should check with a doctor or pharmacist first.
For pregnancy and breastfeeding, there is not enough reliable information to know if silicon supplements are safe. Because of this uncertainty, it is best to avoid silicon supplements during these times and rely on a normal balanced diet instead.
Note that breathing in silica dust (an industrial exposure) is harmful to the lungs, but this is very different from taking silicon supplements by mouth.
Side effects
When taken by mouth at usual amounts, silicon supplements are generally well tolerated. Some people may notice mild digestive upset, such as bloating or stomach discomfort.
Serious side effects from oral silicon supplements are not commonly reported, but high-quality long-term safety data are limited. If you notice any unusual symptoms after starting a supplement, stop taking it and talk with your pharmacist or doctor.
Silicon: Reported Adverse Effects
Documented safety reports on Silicon from the evidence-graded Natural Medicines (TRC Healthcare) database, shown word-for-word from the licensed record.
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.
Acute bronchitis 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. 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. An analysis of 19 studies shows that lung cancer risk is approximately 2 times higher for those with silicosis. It is not clear whether silicon dioxide is carcinogenic in the absence of silicosis.

Cirrhosis Hepatic
High silicon levels in patients undergoing chronic hemodialysis have been associated with liver disease.
Kidney stones (nephrolithiasis) 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. 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. Their formation is caused by an acidic urinary pH. In at least one case, urine alkalinization resulted in resolution of the symptoms.
Case-control studies have shown that occupational exposure to silicon dioxide is related to antineutrophil cytoplasmic antibody (ANCA)-associated glomerulonephritis. High silicon levels in patients undergoing chronic hemodialysis have been associated with nephropathy.

Neuropathic pain Neurologic/CNS
High silicon levels in patients undergoing chronic hemodialysis have been associated with neuropathy.
Rheumatoid arthritis (RA) Musculoskeletal
High silicon levels in patients undergoing chronic hemodialysis have been associated with bone disease. A meta-analysis suggests that the risk of rheumatoid arthritis is elevated with occupational exposure to silicon dioxide.
Scleroderma Dermatologic
Occupational silica exposure may be a risk factor for scleroderma, particularly in males.

Dosing
There is no official recommended dose for silicon as a supplement, and an established upper limit has not been clearly set. Doses used in studies have varied widely depending on the form (such as silica, silicic acid, or choline-stabilized orthosilicic acid).
Because there is no standard dose, the best advice is to follow the directions on the product label and not exceed them. Talk with a pharmacist or doctor before starting, especially if you have a health condition or take other medicines, so they can help you decide whether a supplement is appropriate for you.
