How does crystalline silica affect your kidneys


Silicon-containing minerals and sediments

Silica has fallen into disrepute in recent years. Products in which quartz and cristobalite were found play a special role. The real silica from diatoms is traditionally considered a beauty product and helps against brittle nails, hair loss and skin blemishes.

Silica - a collective term

Silica is a general generic term for minerals and sediments with a high silicon content.

Already knew?

Minerals with a high proportion of quartz and aluminosilicates such as carolines are also known as silica.

Chemically, it is silicon dioxide and not silicic acid. Beyond that biogenically formed sediments referred to as silica: those made from fossil fuels Diatoms extracted silica is traditional as a remedy. It is also called real silica or Silicea terra designated.

Synonyms: Mountain meal | Celite | Diatomaceous earth | Kieselguhr | Pebble flour | Silica | Solum diatomeae | Solum Diatomeae | Terra Silicea

Effect of silica

The real silica The silicon-containing cell envelope of the diatoms becomes due to the high silicon content traditional for prevention brittle nails and hair as well as for Tightening of the connective tissue used. In addition, silica is said to be Prevent hair loss and Inhibit inflammation. Athletes like to strengthen their ligaments with silica to protect themselves from injury. But what can silica really do? Efficacy research is still in its infancy.

A study by the University Medical Center Hamburg-Eppendorf (UKE) showed that the subjects' hair looked fuller after taking silica gel every day. The hair thickness increased by 13%. The head of the study, Professor Matthias Augustin, assumes that silicon strengthens certain protein compounds. These in turn are responsible for the stability of the hair. A study by the Dermatology Clinic at the City of Karlsruhe Clinic was also able to demonstrate an improvement in hair quality. 79 test persons took 350 mg silica three times a day for a period of 6 months.1

Active ingredient silicon

silicon (in chemical terminology Silicon) occurs in our body in cartilage, bones and connective tissue as well as skin and skin appendages. Hence, scientists assume that silicon is needed for the formation and maturation of bones.

Already knew?

In one study, calves were given Orthosilcat, which led to increased collagen formation in the skin and cartilage.2

The daily requirement for silicon is estimated at 10-14 mg. As a rule, we take in sufficient silicon through food. Increased intake is not recommended, as an excess can lead to hemolysis of red blood cells and thus to cell changes.

Already knew?

The name “silicon” is derived from the Latin term “silex” for pebble stone. That’s not surprising. Silicon is mainly found in minerals. Our earth consists of about 15 percent by mass silicon. The earth's mantle in particular has a high proportion of silicate rock melt. sand consists predominantly and quartz 100% silicon dioxide. Silicon dioxide is the main component in many gemstones and, after all, a high proportion of silicon is found in our oceans.

After iron and zinc, it is the third most abundant trace element in our body at 1–2 g.

In addition, silicon is also found in water, wine and beer to a not inconsiderable proportion. In animal products, however, the proportion is very low.

As mentioned above, it has been shown in animal experiments that silicon improves the mineralization of bone tissue and has a positive influence on the formation of cartilage and connective tissue. However, silicon and its effects on the human body have not been adequately researched. If you add too much silicon to the body, it can develop Kidney or urinary stones form.

Other ingredients of silica

Iron, calcium, phosphorus and magnesium are also found in small amounts in silica.

Use of silica

Silica has been used for a long time Means for strengthening the nails and hair used.

As Treatment in the form of tablets or capsules Silica is used to treat:

  • Blemishes, such as acne
  • Joint problems
  • Bone problems

Capsules are particularly suitable for taking silica, as this bypasses its somewhat low water solubility and the mineral can be taken more easily. For mineral supplements, silica is often offered in combination with other important minerals, supplements and trace elements.

Creams and ointments with silica are used for:

Next to it is silica Part of many cosmetic products. If you stick to the recommended dosage, side effects are rare. Hypersensitivity reactions can sometimes occur.

Products under criticism

The Federal Institute for Materials Research and Testing has examined the ingredients of some preparations. In three out of four samples were instead of algae powder the significantly cheaper quartz and cristobalite detected. In the long run, these can lead to kidney damage. That comes to a similar conclusion Institute for Mineralogy at the University of Hamburg. Both substances are crystalline forms of silicon dioxide. Finely ground, these are considered “hazardous materials” in industrial areas. If the fine quartz dust is inhaled, the risk of developing lung tumors increases. The Fraunhofer Institute for Toxicology in Hanover confirmed that a health risk cannot be ruled out if the quartz-containing preparations are taken. The Consumer protection ministries in some federal states they assume consumer deception and doubt the marketability of some preparations. On the other hand, quartz and cristobalite are legally permitted as ingredients in dietary supplements.

Be sure to:

Silicea terra, the real silica, is not crystalline. It has an amorphous structure and is obtained from diatoms.
