Silica Supports Connective Tissues

Silica (SiO2) is actually NOT bio-available. It’s very hard, found in rock crystals such as quartz or flint, and used to make glass.

The Silica we write about (CH3-Si-(OH)3) is methylated and bio-available, not beach sand.

Methylated and Bio-available Silica

Anti-aging Nutrient for Joints and Skin

Topically and Orally

It’s part of your arteries, tendons, skin, connective tissue and eyes.

Benefits of Supplementation

New research shows Silica to be as important to bone health as calcium, magnesium, phosphorus, boron and strontium.

  • Silica promotes firmness and strength in the connective tissues
  • Critical to form and maintain strong bones and teeth (gums too)
  • Helps skin maintain elasticity
  • Promotes strength in hair and nails.

Other possible uses of silica that are under investigation are:

  • May reduce the risk of heart disease (the aorta of a 50 year old contains only half the silica as it did at age 10)
  • Helps treat joint inflammation, cartilage problems, digestive issues, and other conditions where tissue repair and healing are needed
  • May help to heal fractures (may prevent/treat weak bones).

Deficiency  symptoms can be seen as lackluster hair, soft and splitting nails, wrinkly and sagging skin.

Silica Supports Collagen Production

Silica is present in collagen (a glue that holds us together). Collagen holds calcium, magnesium and phosphorous in place, giving bone strength AND flexibility to resist fractures.

More women are dying of complications from brittle bone fractures, than cancers of the breast, cervix and uterus combined.

A University of California study showed twice the collagen in bones with sufficient silica, over that of bones with low silica.

Supporting Research

The famous China Diet Study found that bone loss is very rare among vegetarians (only 544mg  calcium daily), while osteoporosis is quite high among meat and dairy products consumers who get over twice as much calcium (1143mg calcium daily). While the vegetarians didn’t get as much calcium, they did get plenty of plant-grown silica . This more than makes up the difference. Most of us easily get the 544mg of calcium. What we are less likely to get is the silica, which is tougher to find in the right form to absorb and use.

  • In 1878, Louis Pasteur declared that in the future Silica would become an optimal therapeutic agent.
  • In 1939, Nobel Prize winner, Professor Adolf Butenant found Silica to be essential to human life.
  • In 1972, Columbia University scientists confirmed that Silica must be continuously supplied from food sources, yet there is still no official RDA.
  • According to Klaus Kaufman, a leading Silica researcher, Silica is the most important antioxidant.
  • Researchers in Germany have noted a correlation between higher than average levels of Silica intake and reduced rates of cancer.
  • Results of studies on rats with silicon-deficient diets show decreased growth, and deficient bone and tooth structure.
  • Results of studies on rabbits with silicon-deficient diets show more atherosclerotic arterial plaques.
  • Other research reveals that silicon levels affect physical endurance, with low tissue levels correlating with lowered stamina.

Natural Sources of Silica

Silica is widely available in food, but easily lost in food processing. The small amount of Silica left remains locked-up, and is poorly assimilated. Only about 2% of the original silicais left in milled flour.

Silica is found in:

  • High amounts in the hulls of wheat, oats, and rice, in sugar beet and cane pulp, in alfalfa, and in the herbs horsetail, comfrey and nettles
  • Present in lettuce, cucumbers, avocados, strawberries, onions, dandelions and other dark greens
  • The pectin in citrus fruits and alginic acid in Algae/Kelp
  • Hard drinking water may also be a good source.

To get extra silica, eat more whole grains and fresh vegetables, or take  herbs supplements like horsetail, alfalfa or comfrey. Exsula Superfoods Iridesca and AuraSil are excellent sources of Silica.

Silica is the most abundant mineral present in soil, yet our soils have become deficient.

Silica In Your Body

Silica is synergistic with Vitamin C and Bioflavonoids (especially Pycnogenols and Bilberry) for collagen production and firm, youthful skin.

Silica is important for utilization of several other nutrients including vitamins B-6, C, D, K and Folic Acid as well as the minerals Boron, Copper, Fluorine, Magnesium, Manganese, Phosphorus, Strontium, and Zinc.

Notable concentrations of silica are found in the brain, pancreas, arteries and eyes, especially in the iris and cornea.

Silica levels are highest just before birth and decline each year as you age.


There is no RDA (recommended daily allowance) for silica since it is not considered essential. The average diet provides about 1-1.5 grams of this mineral. A diet high in processed foods may diminish silica  intake.
