While many of the studies on silica have been done on animals, researchers have found no link between the food additive silicon dioxide and increased risk of cancer, organ damage, or death. The U.S. Food and Drug Administration (FDA) has also recognized silicon dioxide as a safe food additive.
Is silicon dioxide harmful to humans?
Silicon dioxide is a compound that occurs naturally. It exists abundantly in plants and within the earth’s crust, and even makes its way into humans and other animals. There is still no evidence to suggest that silicon dioxide is dangerous as a food additive. However, regularly inhaling silicon dust is very dangerous.
Is silica a human carcinogen?
Respirable crystalline silica was first listed in the Sixth An- nual Report on Carcinogens in 1991 as reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals; the listing was revised to known to be a human carcinogen in the Ninth Report on Jul 1, 1990
Does silica have side effects?
One of the dangerous effects of silica exposure is a disease called silicosis, which can be contracted after just a few months of high exposure. Silicosis occurs when silica dust enters the lungs and causes the formation of scar tissue, reducing the lungs’ ability to take in oxygen.
What happens if you have too much silica?
In extreme exposure, acute silicosis can develop within months of exposure to high concentrations of silica. Symptoms of silicosis include shortness of breath, severe cough, weight loss, chest pain, bluish coloration, and in some cases fever.
What does silica do to your body?
Silica is an important trace mineral that provides strength and flexibility to the connective tissues of your body — cartilage, tendons, skin, bone, teeth, hair, and blood vessels. Silica is essential in the formation of collagen, the most abundant protein found in your body.
Does silica cause kidney stones?
High oral doses of silicon delivered over many years can lead to the formation of renal stones containing silicates (Flythe, Rueda, Riscoe, & Watnick, 2009) .
What is the health benefits of silicon dioxide?
Silicon is used for weak bones (osteoporosis), heart disease and stroke (cardiovascular disease), Alzheimer’s disease, hair loss, and improving hair and nail quality. It is also used for improving skin healing; and for treating sprains and strains, as well as digestive system disorders.
Is silicon dioxide natural or synthetic?
Silicon dioxide is a naturally occurring substance that is generated following oxidation reactions involving silicon in the Earth’s crust. Silicon dioxide is a major component in sand, quartz, diatomaceous materials, and is found as biogenic silica in organisms.
Is silica same as silicon dioxide?
Silicon dioxide (SiO2), also known as silica, is a natural compound made of two of the earth’s most abundant materials: silicon (Si) and oxygen (O2). Silicon dioxide is most often recognized in the form of quartz. The earth’s crust is 59 percent silica.
Does silica help hair growth?
Silica doesn’t promote hair growth, but it does strengthen hair and prevent thinning. It does this by delivering essential nutrients to your hair follicles. As a bonus, it can also benefit your skin and nails.
What are the first signs of silicosis?
Symptoms of silicosis usually appear after many years of exposure. In early stages, symptoms are mild and include cough, sputum and progressive shortness of breath. As the scarring continues to worsen, the first real signs of a problem may be an abnormal chest X-ray and a slowly developing cough.
Can silica damage your kidneys?
Silica dust particles are tiny, over 100 times smaller than the sand you see on the beaches. If you are exposed to silica dust in the workplace, this can cause many chronic health problems including kidney damage and kidney failure. The more you are exposed, the greater the risk.
Can you recover from silicosis?
There’s no cure for silicosis because the lung damage can’t be reversed. Treatment aims to relieve symptoms and improve quality of life. The condition may continue to get worse, leading to further lung damage and serious disability, although this may happen very slowly over many years.
Why is silica bad for you?
Breathing in very small (“respirable”) crystalline silica particles, causes multiple diseases, including silicosis, an incurable lung disease that leads to disability and death. Respirable crystalline silica also causes lung cancer, chronic obstructive pulmonary disease (COPD), and kidney disease.
Does silicon dioxide cause inflammation?
The results show that synthetic silica nanoparticles can lead to an inflammatory reaction in the intestine. These findings suggest that the concentration of silica nanoparticles in food additives should be reduced. This should be followed up by in-vivo studies and comparisons with human exposure data.
What is the best form of silica to take?

Is it safe to consume silica?
Although consuming silica doesn’t appear to have negative effects, inhaling small particles of it can increase your risk of developing serious silica-related diseases, such as: Silicosis. Lung cancer. Chronic obstructive pulmonary disease.
Is silica in drinking water harmful?
Silica ( quartz/ amourphus) is insoluble in water. However , it may have very very low solubility in hot water. If it is present in domestic / drinking water, indicated contamination of water ( anthropogenic/natural ) and if consume ,may cause forserious serious health hazards.
How long do people live with silicosis?
The survival times of silicosis stage I , II and III, from the year of diagnosis to death, were 21.5, 15.8 and 6.8 years, respectively. There was 25 % of the silicosis patients whose survival time was beyond 33 y. The mean death age of all silicosis cases was 56.0 y.
What is silicon dioxide used for?
Silicon dioxide, also known as synthetic amorphous silica (SAS), is used by food manufacturers as an anti-caking agent in spices or creamers, to ensure fine flowing powders or to absorb water. It is made up of aggregated nano-sized primary particles which are usually greater than 100 nm.
What is the alternative to silicon dioxide?
What RIBUS offers is an alternative to silicon dioxide. It is not “nature identical” but provides the same results for the majority of uses, other than as a defoamer.
