Mirko Beljanski, PhD (1923 - 1998) shared
the same passion that drives the fearless explorer, the patient archeologist
and the innovative inventor: the passion for discovery. The conviction that
a discovery will make a difference in people’s lives is what pushes the
pioneer to overcome any obstacle.
Throughout his career of more than 50 years as a biochemist and biologist,
Dr. Beljanski faced many obstacles but was never swayed from his dedication
to discovery and to improving the lives of others.
From his humble origins in the former Yugoslavia to his days as a researcher at the celebrated Pasteur Institute in Paris, Mirko Beljanski knew his destiny. After receiving his PhD from the University of Paris, he began working at the Pasteur Institute, where he and his team devoted much of their study to cell regulation and replication, and especially the role DNA and RNA play in cellular health.
As his team probed the innermost mechanisms of cell replication, Beljanski
became particularly focused on aberrant physiological cell regulation,
what happens when normal cell behavior goes awry. In 1960 he was awarded
the Charles Leopold Mayer prize for his outstanding work on RNA synthesis,
the core mechanism in cell multiplication. His discoveries led him to
isolate and study several new substances which led to breakthroughs in
his field and, ultimately, a line of dietary supplements, the Beljanski® products.
When he passed away in 1998, he left behind him a legacy of fearless innovation
and an impressive body of work that includes two books, 133 articles
published in peer-reviewed scientific journals and numerous patents.
Most importantly, his lifelong dream of bringing Nature and Science together
to improve the health and well-being of people was achieved.
THE INNOVATIONS
DNA and RNA are found within the nucleus of every living cell. DNA contains
the unique genetic code for each individual organism, while RNA controls
the activity of the cell. Dr. Beljanski made a fundamental discovery: the
DNA extracted from tissue in which the cells have been irregularly multiplying
has a destabilized secondary structure not found in DNA taken from healthy
tissue. All of the substances able to modify this structure trigger the
gene's expression and cause the destabilized DNA to dramatically increase
replication. Once the process has started, it gains momentum with each
division.
Dr. Beljanski realized that if he could find a way to prevent the uncontrolled
replication and expression of destabilized DNA then he might be able to destroy
these unhealthy cells.
After years of research, he discovered these properties in certain plant extracts.
These extracts proved to exhibit selective action, acting only on those cells
which have been destabilized and leaving healthy cells untouched. This scientific
realization forms the basis of the Beljanski® products.
PRODUCT MANUFACTURING 
Natural Source International, Ltd. painstakingly
selects only the highest quality ingredients for use in its products.
Preparation of these ingredients is based upon the similar high standards
that Dr. Beljanski himself used in his research. Our careful attention to quality
control assures that each batch of plant extracts meets the chemical specifications
established in Dr. Beljanski’s patents. Anything less would not be
worthy of carrying the Beljanski® name.
Pao Pereira (Pau Pereira) raw material is harvested in South America from
the heart of the Amazon rain forest. Rauwolfia vomitoria is collected
from the root of a tropical
African shrub. Our Ginkgo biloba extract, which comes from special golden leaves
of the gingko tree, is prepared
according to a particular extraction method that provides a unique profile of
active plant compounds, different from those currently found in any other
standardized ginkgo extract. Quality controls are performed at every
step of the manufacturing process: from extraction to purification to
encapsulation. Only when each batch of the Beljanski® extracts
has passed our exhaustive tests are they finally encapsulated in 100%
vegetarian capsules.
