Silicon is a very common element in nature in a chemically combined state. It constitutes approximately 27.7% of the Earth's crust, making it the second most common natural element after oxygen.
The major biological role of organic silicon
According to the majority of Paleoanthropologists, modern man originated in Africa,between 100,000 and 300,000 years ago. During the last 100,000 years, these experts believe that human biology has not evolved significantly. Consequently, they claim that our nutritional needs are dictated more by what our ancestors ate than by the food we eat today. Certain of the foodstuffs our ancestors ate have completely disappeared from our modern lifestyle - in particular, internal organs, marrow, skin, tendons, cartilage, bony fish and fibrous plants. Unlike the average diet of today, these foods were rich in silicon.
Contrary to long held belief, silicon is one of the twelve major elements that enter into the elementary composition of organisms. Silicon, even in a trace state, plays a major biological role and must be regarded as an essential element of life. It is necessary, in particular, for the normal growth of many species by catalysis and/or synergy.
Human blood contains nearly 10 mg per litre (one tenth that of calcium). The body contains approximately 7gr of silicon, more than iron (3 to 3.5gr), much more thancopper (100 to 150 Mg), and even more than cobalt, nickel, zinc, etc.
It is mainly present in the bones, the vascular walls, the spleen, the tendons, the muscles, the suprarenals, the pancreas, the liver,the kidneys, the heart, the thyroid and the thymus. Recent studies have shown that the human foetus is very rich in Silicon, this reserve being naturally adapted to bone formation and maintenance.
 The silicon content of the richest tissues (skin, arteries, thymus) reduces enormously with age: by over 80% between sexual maturity and death.
Naturally available silicon is present primarily in non soluble form and is thus not very easily assimilated by the body. Moreover, even in soluble form, silicon is not stable because it has a tendency to quickly polymerise.
This explains the relative success silicon-based products in therapeutic applications
After several years of research, DexSil labs. have developed a range of readily assimilated silicon that also has very good antioxidant properties and significant bio availability.
