How much silica is too much?
How much silica is safe to take? The upper safe limit has been reported as 700–1,750 mg a day. As silica is water-soluble, excess is simply passed out by the body in your urine, meaning it's unlikely to cause side effects if you take too much.
The silica content of the dust to which workers developing simple silicosis are exposed is often less than 30%. Accelerated and acute silicosis develop after shorter exposures to respirable silica dust at high concentrations.
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.
Fortunately, like hard water, silica does not pose a danger to health. Silica is not considered harmful if ingested in small quantities in drinking water. In fact, many foods such as onions, wheat, oats, root vegetables, and strawberries contain silica.
Based on the data analyzed for Longview's water, no adverse health effects are expected from silica, even at the maximum concentration measured. The maximum silica concentration in water is equivalent to 9.2 mg silica per 100 g (about 3.5 oz) of water, less than the amount found in dried fruits and breakfast cereals.
The Food and Drug Administration (FDA) recommends that you don't consume more than 10-30 grams, or 2% of your daily food intake (500-1,500 grams), of silica per day.
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.
Crystalline silica is a designated known human carcinogen meaning it is a definite cause of cancer in humans. Once you breathe it in it can go deep into your lungs and stay there - permanently scarring and damaging the lung tissue.
Your body can get rid of some dust you breathe in. But if you work in a job where you are exposed to high levels of dust for a long time, or work with products containing a high amount of silica, then your lungs become overwhelmed. As a result, your lungs can't get rid of all the dust.
Silica dust particles become trapped in lung tissue causing inflammation and scarring. The particles also reduce the lungs' ability to take in oxygen. This condition is called silicosis. Silicosis results in permanent lung damage and is a progressive, debilitating, and sometimes fatal disease.
What does silica do to your brain?
Fights brain toxins: Research indicates that silica reduces aluminum build-up in the brain, which researchers have potentially linked to Alzheimer's disease. So the elderly and others at risk for this disease may benefit from silica supplementation, especially since silica levels in your body tend to decrease with age.
Occupational exposure to silica may be associated with chronic kidney disease (CKD). Most studies have been conducted in occupational cohorts with high levels of exposure but small numbers of cases.
The most common and effective technique for removing granular silica from boiler water is lime softening. This process involves adding lime, also known as calcium hydroxide, to the water. Lime acts like a water softener for silica, causing calcium and magnesium — the particles that cause hardness — to precipitate out.
Silica water differs significantly from most mineral waters, as it contains higher levels of silicon than most bottled water. Silicon in soluble form is known as Orthosilicic Acid(OSA) and is usually listed on bottled water labels as Silica measured in milligrams per litre.
The silica content of tap water can vary according to geographic region, with typically high silica levels in hard-water areas and low levels in soft-water areas.
Magnesium, like silica and calcium, is associated with strong bones (via The Journal of Nutrition, Health & Aging), so drinking Fiji water is healthy in that regard, too.
Crystalline silica is considered the toxic form of inhaled silica while less is known about the toxicity of amorphous silica.
Soluble silica and coral sand suppress high blood pressure and improve the related aortic gene expressions in spontaneously hypertensive rats. Nutr Res.
Boosts the Immune System
Since silica is a vital part of healthy skin and digestive tissue, it is also important in preventing illness and infection. The skin and our digestive system are the first lines of defense we have against pathogens.
For a well-sealed item, a rule of thumb is that 10 grams of silica gel is needed for every 30cm cube of volume of the package.
How do you know if you have silica in your lungs?
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.
Silicosis is a work-related lung disease — you get it because you're breathing in silica crystals at your job. You can't cure or reverse silicosis, but your providers can treat it.
Exposure to silica dust can lead to the development of lung cancer, silicosis (an irreversible scarring and stiffening of the lungs), kidney disease and chronic obstructive pulmonary disease. It is estimated that 230 people develop lung cancer each year as a result of past exposure to silica dust at work.
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. Be sure to speak with your doctor before trying silica for hair loss.
Much of the absorbed silica is eliminated within 4-8 hr following its ingestion (30,47,61,62,64). Indeed, the renal clearance of Si, is high (82-96 ml/min) (61,62). However, absorbed silica is also likely to be taken up by tissues which may delay its total elimination from the body.
Not everyone who works with silica dust develops silicosis. The chances of getting silicosis will depend on many factors, including how much silica dust you come into contact with, and for how long you were exposed to it.
There is no specific treatment for silicosis. Removing the source of silica exposure is important to prevent the disease from getting worse. Supportive treatment includes cough medicine, bronchodilators, and oxygen if needed. Antibiotics are prescribed for respiratory infections as needed.
In order to make a diagnosis of silicosis, a history of exposure to respirable crystalline silica is needed. Clinical evidence of the disease through chest x-rays or computerized tomography (CT scans) or a lung biopsy is also needed. As appropriate, it is also necessary to exclude alternative diagnoses.
Silicosis IS NOT CURABLE, but it IS PREVENTABLE—to live a long and healthy life, learn the facts and know how to protect yourself and your family.
Eye Exposure If crystalline silica dust gets into the eyes, wash eyes immediately with large amounts of water, lifting the lower and upper lids occasionally. If irritation is present after washing, get medical attention.
Can silica cross the blood brain barrier?
The promising results obtained by in vivo experiments, point out that silica nanoparticle derivatives are an efficient permeable delivery vehicle that are able to cross the BBB and reach the brain tissues via specific and non-specific mechanisms.
Silica can help lubricate your joints: Silica has been shown to stabilize and lubricate your joints while also reducing the levels of inflammation in your joint tissues.
In the human body, silica is essential for bone formation and the health of connective tissue. Healthy hair, skin, nails and flexible arteries would be impossible without silica. Silica is critical to our well being, but it's difficult to assimilate from a normal diet.
Crystalline silica is well known to induce chronic lung inflammation by inhalation that can progress to silicosis. Recently, we reported that silica nanoparticles (SN) cause more damage to liver instead of lung when they enter the body by intravenous injection.
"Silica is a natural anti-inflammatory, so it may help relieve skin conditions like psoriasis and eczema," says Somenek.
The fact that silicon dioxide is found in plants and drinking water suggests it's safe. Research has shown that the silica we consume through our diets doesn't accumulate in our bodies.
Silica is a hard, ceramic/sand like mineral formed from Silicon and Oxygen. It is frequently found in water supplies as a colloid or in ultra fine particulate form. Water softeners don't remove it and carbon filters don't remove it, neither do Iron filters or cartridge filters!
Use the following methods to control respirable crystalline silica: Use the dust collection systems available for many types of dust-generating equipment. When purchasing equipment, look for dust controls. Use local exhaust ventilation to prevent dust from being released into the air.
The most efficient way to gain control of silicate in tap water is with a reverse osmosis (RO) filtration system. Many reef-keepers already use RO/DI water to mix saltwater and freshwater top-offs.
Volcanic Eruptions: High Silica
Lava with high silica content is thick and viscous and does not readily flow. Lava rises up toward the surface but is too thick to squeeze through the cracks and fissures in the Earth. As lava continues to rise upward, pressure continues to build.
Why do we measure silica in water?
Why Test Water for Silica? The silica content of water should be determined prior to its use in industrial applications as silica can form a harmful scale on equipment and heat transfer surfaces, particularly steam turbine blades. Silica will also foul reverse osmosis membranes reducing efficiency.

Silicon is the 7th most abundant element in the universe and the second most abundant element on earth after oxygen which explains why most water supplies will contain some traces of silica. All natural water supplies contain some dissolved “silica” and most will also contain suspended or colloidal silica.
Membrane fouling occurs when silica particles lodge in the membrane's pores, obstructing the normal flow of liquids through the membrane. Additionally, because silica particles are abrasive, they can also cause premature tears and weakening of delicate filtration membrane materials.
We have shown that drinking up to 1 L of a silicon-rich mineral water each day for 12 weeks facilitated the removal of aluminum via the urine in both patient and control groups without any concomitant affect upon the urinary excretion of the essential metals, iron and copper.
Overdose. Silica has a very low risk for toxicity when taken orally. The EFSA note that even after administering very high doses of up to 9,000 milligrams of silica per kilogram of body weight, no adverse effects appeared.
How much dust is too much dust? The typical exposures to silica in the building and construction industry are required by law to be limited to a maximum exposure of 0.1mg/m3 with many countries restricting it further to 0.05mg/m3 or as low as 0.025 in some states of Canada.
The big difference? Collagen provides the readily available base for an instant collagen 'top up' while silica helps to make collagen so will take longer for any noticeable effect.
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. Be sure to speak with your doctor before trying silica for hair loss.
The recommended daily amount of silica for adults ranging in age from 19-50 years old is 9-14 mg/day. Silica is found in plants and some herbs such as horsetail, and in high-fiber foods including whole grains, rice, fruits, and vegetables.
What are the symptoms of silica poisoning?
These commonly include bronchitis-like symptoms such as persistent cough, shortness of breath and difficulty breathing. People also suffer from weakness, fatigue, fever, night sweats, leg swelling and bluish discoloration of the lips.
Another trace element that may be important is silicon (Si), but although there is 1-2 g present in the body (the most abundant trace element after iron and zinc, two other elements of physiological importance) its function is still surprisingly unclear.
Silica can help you have more youthful and firm skin by producing collagen. Collagen supplements keep your skin firm and elastic and reduces the appearance of fine lines and wrinkles. A study in 2005 found that silica improved the rough texture of women's sun-damaged skin.
Silica is important in building a strong stomach and digestive tract muscles and tissues. Silica assists in rebuilding and fortifying these tissues after they have been damaged by poor diet, parasites, age, or other injuries.
