Is silica harmful to humans?
Inhaling crystalline silica can lead to serious, sometimes fatal illnesses including silicosis, lung cancer, tuberculosis (in those with silicosis), and chronic obstructive pulmonary disease (COPD). In addition, silica exposure has been linked to other illnesses including renal disease and other cancers.
What is silica used for?
Silica also is used in grinding and polishing glass and stone; in foundry molds; in the manufacture of glass, ceramics, silicon carbide, ferrosilicon, and silicones; as a refractory material; and as gemstones. Silica gel is often used as a desiccant to remove moisture.
What exactly is silica?
Silica is another name for silicon dioxide, a molecule composed of one silicon and two oxygen atoms, among the most abundant elements in the Earth’s crust. Sand is mostly silicon dioxide and quartz is a common crystal form of it. Glass is also made with it. Silica gel packets in the seaweed contain hard little beads.
Is silica safe to consume?
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.
Why is silica in food?
Why is silicon dioxide used in food additives? Manufacturers use silica to make everything from glass to cement, but it also has a use in the food industry as an additive and anticaking agent. This type of food additive prevents foods from caking or sticking together in clumps.
Why is silica used in food?
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 does silica do for the skin?
Studies have shown that the use of silica both topically and internally significantly improves the elasticity, texture and hydration of the skin, as well as reducing visible signs of ageing[v].
Is silica A plastic?
The plastics industry considers silicone a plastic, and so do we, regardless of much of the green marketing claiming it is not a plastic. Technically, silicone could be considered part of the rubber family. Silicone can be used to make malleable rubber-like items, hard resins, and spreadable fluids.
What does silica do to your hair?
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.
Do humans need silica?
Why do you need silica? 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.
What are the side effects of taking silica?
Long term inhalation of silica dust may lead to issues in the lungs, including:
- silicosis, a progressive, irreversible lung disease.
- lung cancer.
- chronic obstructive pulmonary disease, or COPD.
- increased risk of tuberculosis.
What are the dangers of silica?
Prolonged exposure to crystalline silica may cause toxicity. Lung damage and chronic obstructive pulmonary disease are common side effects. However, crystalline silica has a different chemical makeup than dietary silica, so the dietary form doesn’t carry these risks.
Why is silica bad for You?
Long answer. Silica also acts as a diuretic, which can be dangerous for anyone taking a “water pill.” Taking both together can lead to dehydration from the excessive water loss in the body, which can also cause electrolyte imbalance. Potassium is typically the most affected by this situation, as levels become very low.
What are the benefits of taking silica?
Health Benefits of Silica on Joints: Silica is known to be essential for our joints.
What does silica do for the body?
According to researchers, silica is a form of silicon. This natural element plays a key role in collagen synthesis, immune function, bone mineralization and mental health. It is also the third most abundant trace mineral in your body. Most studies suggest that ortho-silicic acid exhibits therapeutic effects and may benefit overall health.
