Humic acids are formed by the decomposition of organic residues. Thanks to their properties, they act as the “glue” of soil colloids, binding insoluble ions and releasing them as plants require. Humic acids modify soil structure, preventing water loss and erosion in sandy soils and improving aeration in compact soils. They have a beneficial effect on seed germination, their viability. In addition to the effect on germination and plant growth, the effect of humic acids on the multiplication of beneficial soil microorganisms, as well as stimulating the immune system of plants can also be observed. They have the ability to bind insoluble metal ions, oxides and hydroxides and release them slowly as needed by the plant. Due to their properties, we can speak of three types of action: physical, chemical and biological.
  • modify the soil structure, 
  • increase the water holding capacity of the soil and thus reduce the risk of drought,
  • prevent soil cracking, surface water runoff and soil erosion by increasing the water binding capacity of colloids,

Chitozn is a natural, non-toxic, biodegradable and biofunctional polymer, safe for the human body and the environment.  It is obtained from the shells of marine crustaceans by deacetylation of chitin, which, after cellulose, is the most abundant organic material found in nature. It shows antibacterial, antifungal and antioxidant properties.

Chitosan is a polymer commonly found in nature. It is obtained from chitin, which is a structural material of crustaceans (shrimps, crabs, crayfish, krill), insects, fungi and bacteria. It is a polysaccharide with a molecular structure very similar to cellulose. As a compound of natural origin, non-toxic and biodegradable, it is completely safe for the environment.

In terms of chemical structure, it is a polysaccharide composed of many amino sugar molecules, connected to each other by β 1-4 bonds. This amino sugar is chitosamine (D-glucosamine), which is a derivative of D-glucose, in which the OH group in the second position has been substituted with an amino group (NH2). In comparison, cellulose is a polysaccharide composed of D-glucose molecules also linked by a β1-4 bond.

The term chitosan is used for compounds formed by deacetylation of chitin as a result of the action of concentrated alkali at elevated temperature, which leads to a gradual elimination of acetate groups and formation of free amino groups in the glycosidic rings of the biopolymer.

It is assumed that in its natural form chitin occurs in a partially acetylated form i.e. through OH or NH2 groups the acetyl group CH3-C=o is attached ( furda 1983).

Interestingly, despite its close affinity to cellulose, chitin does not occur in higher plants. However, it shows high biological activity in relation to it, e.g. increasing the resistance of plants to unfavourable environmental conditions, to fungal and bacterial infections.


Effects of chitosan oligomers on human health:

Researchers have shown that the substances discovered are polymeric inhibitors. They were created on the basis of chitosan – a compound obtained from marine crustaceans. The effect of the polymer is that it binds to the protein that forms the “crown” of the virus and blocks its interaction with the cell receptor, and consequently the entry of the virus into the cell. 

Chitosan, from which polymeric compounds are obtained, is chemically an organic compound of the polysaccharide group; a derivative of chitin, formed by its partial deacetylation.
Deacetylation of chitin involves the removal of acetyl groups from chitin, which harden and cement chitin. The highest biochemical activity of chitosan is obtained when it is processed through the patented OCHG™ process. The result is chitosan lactate or chitosan in the form of oligomers, or polymers, with short chains and a well-defined molecular weight. Structurally, chitosan is a cellulose (fiber) of animal origin, similar to human fibrin. It is completely natural and well tolerated by our body.
Chitosan has a very beneficial effect on the entire body. Experts call it the sixth essential component of life after proteins, fats, sugars, minerals and vitamins. It effectively purifies and deacidifies the body, stimulates the human defense mechanisms, does not allow cancer cells to multiply, lowers cholesterol, helps reduce body weight. With the help of chitosan it is possible to overcome many diseases with which modern medicine cannot cope.

CHITOZIN FIT C contains liquid chitosan lactate in the form of oligomers. It is characterized by very high bioavailability and biochemical activity, which gives it the highest effectiveness among other known products containing chitosan.


Experimental studies confirm the antimicrobial mechanism of action of chitosan. It is related to the breakdown of the cell wall structure due to free amino groups present in chitosan. The positively charged chitosan interacts with the negatively charged chemical bonds in the cell wall of bacteria or viruses, causing them to break down. This occurs through electrostatic forces acting between protonated amino groups and negative residues, competing for electro-negative sites on the surface of the microbial cell membrane. This interaction alters
permeability of the cell membrane, and contributes to its breakdown and leakage of intracellular matter.

Other studies suggest that a polymeric envelope forms around the cell membrane of microorganisms, that is, chitosan forms a kind of shell over the microorganism’s cell that prevents
nutrients from entering that cell. Another discovered mechanism of action of Chitosan is the binding of chitosan molecules to microbial or viral DNA, which leads to
inhibition of mRNA and protein synthesis.

Chitosan molecules have been shown to be able to penetrate the cell wall of bacteria and reach their genetic material.

It works on all organs, improves the general condition of the body, raising the pH to 7.35 – 7.4. deacidifies the body. Acidification of the body causes disruption of all biochemical processes of the body,
thickening of the blood, circulation disorders, puts great strain on the kidneys, causes joint and muscle pains and promotes the growth of cancer cells. In an alkaline environment, cancer cells do not reproduce.
Therefore, chitosan used in higher doses causes cancer cell death and reduces the size of tumors

Chitosan cleanses the digestive tract, liver and entire body of heavy metals and toxins by binding and excreting them from the body. Research results indicate that it is very effective in improving the condition and functioning of
liver and pancreas. Chitosan also binds chlorine ions from table salt and excretes them, which prevents the production of angiotensin, a substance that causes rapid vasoconstriction. As a result, it has a hypotensive effect,
by lowering blood pressure. The product binds and excretes cholesterol from the gastrointestinal tract because it has positively charged amino groups at the same pH as the gastrointestinal tract. The amino groups bind
to negatively charged molecules such as lipids and bile, preventing their absorption and storage by the body. The effect of chitosan in lowering LDL cholesterol levels can be
explained by the theory that chitosan salts react with fatty acids and bind lipids via a hydrophobic interaction mechanism. Such bound lipids are excreted from the gastrointestinal tract along with other
The chitosan salts react with fatty acids and bind lipids by hydrophobic interactions.

When it dissolves, a coating is formed that acts as a shield, eliminates hyperacidity, stimulates healing processes, heals erosions, ulcers and mucosal defects. Mucosal defects are the cause of leaky gut
(“Leaky Gut Syndrome”). Leaky Gut Syndrome is one of the leading causes of allergies and autoimmune diseases because undigested nutrients (e.g. casein, gluten) and toxins
penetrate through holes in the intestinal mucosa, enter the bloodstream and consequently trigger an immune response from the immune system

Leaky gut syndrome is often caused by Candida yeast. Candida albicans is a parasitic fungus that lives in the human digestive tract. If there is dysbiosis, or a disruption in the normal composition of the intestinal microbiota, candida begins to proliferate and dominate. As a result, they secrete a number of toxins and metabolites that enter the bloodstream and poison the entire body. This adversely affects a number of processes in the body, disrupts its functioning leading to diseases, including cancer. Chitosan oligomers effectively inhibit Candida.

Hyaluronic acid is also a major component of joint synovia. It is responsible for the viscosity of the synovium, lubricating joint surfaces and nourishing cartilage. This is why chitosan, when used for a longer period of time, improves
joint mobility.
