The LSA Pro by Zyto (Now called ZYTO Elite): Taking the Guesswork out of Wellness!

ZYTO: Our feature technology, the LSA Pro, enables us to perform a Bio-Survey of your body which allows us to evaluate the stress of each of your body's systems, identify the underlying cause of stress in each of these systems, and pinpoint the exact remedies which will bring your body back into balance.  Click here for a printable brochure

How it works:By combining quantum physics, biology, and information theory, ZYTO technology provides an interface between living things and computers allowing them to talk to each other.

Most of your daily activity is managed by an exchange of information that happens at a level below conscious awareness. Every second there are an estimated 100 million impulses of information processed by your body that you are not aware of. The mechanism that filters this information is a part of your brain called the reticular activating system and even though you aren’t aware of it, it is this information that keeps your body organized and healthy.


How Our Cells Communicate:

Information is the communication of knowledge and each cell of your body is built for communication. The outer cell wall is comprised of two layers of fat, called a bi-lipid layer. The lipid molecules are organized in a crystalline pattern that facilitates communication.

You may be familiar with crystals and their use. Using very simple components, and no outside energy source, a crystal radio allows you to capture the waves from a radio station and convert them into audio energy.

The crystal like structure of each of the 70 trillion cells that make up your body allows you to receive information in a similar way. As the cells compress and expand their structure generates the energy needed to pass information along, allowing your entire body to function in a coordinated and healthy way.

As your cells communicate ZYTO technology makes it possible to ‘eaves drop’ and listen to the conversation. This is accomplished by monitoring the changes in galvanic skin response, or GSR, as well as subtle changes in spoken voice. As we listen we apply proprietary formulas and extract meaning from what your body is saying; but that’s only half the equation, the other half is talking. Talking in this sense is communicating information to your body that will stimulate a response.

To talk to your body ZYTO technology converts computer data to signatures or frequencies that stimulate cellular response. We call these signatures virtual stressors or queries. The process of talking with the body can be seen as a stimulus-response exercise. ZYTO technology outputs a query (a virtual stressor) and the body responds. We’re asking a question and listening to the answer.

The History

The LSA ProTM is a bio-information tool designed to assist health professionals gather patient-specific information. It facilitates a conversation between the computer and the patient at an autonomic or subconscious level. This conversation is essentially an extension of the intake process involving a written health history, as the LSA Pro can be compared to the health history form and the pen used to fill in the blanks. Although the printed form and the pen are not medical devices the information they collect can have significant clinical value.  This is also true for the LSA Pro; gathering information is the objective. Information is the transmission of knowledge.

There are various ways to transmit knowledge.  The communication pathway that the LSA Pro accesses is Galvanic Skin Response or GSR. GSR is concerned with the conductivity (how well something conducts electricity) of the largest organ in the body, the skin.

A German Professor named Tarchanoff first discovered skin conductivity around 1888. In the early 1900's Dr. Carl Jung established that GSR measurements could track physiological arousal or stress in the body. In the 1930’s Dr. Hans Selye began to uncover the importance of understanding stress and what information it could tell us about the body. These discoveries have led to the creation of many common devices, such as the polygraph test. Later in the 20th century, Dr. Reinholt Voll and others identified further uses for GSR, including the monitoring of acupuncture points to determine the condition of the body's energy meridians.

In the 1980’s, Dr. Vaughn R Cook began to build on these applications. The initial goal was to use computers and GSR to gather data to aid healthcare professionals in making diagnostic and therapeutic decisions. After designing one such instrument he began in 2001 to design a fully automated device that could expand into non-clinical use. However, the first such application was the LSA Pro, released after three years of development in late 2004.

Much like a polygraph technician asking a subject questions and evaluating the body's response, the LSA Pro uses GSR to track responses to computer generated signatures called ‘queries’, or ‘virtual stressors’. The LSA Pro asks the body questions by generating a query and monitors corresponding fluctuations in GRS to record its answers.

Initially the LSA Pro determines what is called the patient’s stress profile. A stress profile is comprised of the most exaggerated responses to a given set of queries. These responses are considered ‘out of range’ or significant enough that they warrant further attention. The LSA Pro then uses the stress profile as a measure against which further queries are rated.  These further queries help identify balancing options, including nutriceutical products.

Just like the written health history, this information serves as a guide for clinical decisions.  Are specific diagnostic tests warranted?  Which therapeutic query is the patient showing the most positive (balancing) response? The LSA Pro quickly gathers and assesses data that would otherwise be missed.

China Study (200 participants): Remote health assessment using a ZYTO frequency-based GSR Stress Bio-Survey Technology. The results showed an 87% congruency in the disease assessment of two or more of the four primary diagnosed unhealthy or stressed organ systems.

7 Questions People Commonly Ask About Zyto Technology

Stress as a Communication Pathway

Most often, when we hear the word stress we think of anxiety or nervous tension. The clinical definition of stress however is a positive thing. In fact, without stress you'd be dead. Physiological stress is your body's reaction to any stressor. It is generated in an attempt to maintain balance. Stressors can be environmental, emotional, or physical. For example, fatigue from staying up too late, the emotional strain from a death in the family, or a flu virus that has invaded your body are all stressors.

When a stressor presents itself your body uses biotelemetry to spread the word, communicating from cell to cell to enlist sufficient resources to compensate for the stressor. When the body’s response is adequate we continue to enjoy good health, we are in balance with our stressors. This is called homeostasis.  Homeostasis is not a static position; the body is constantly making adjustments, an estimated 100 million per second. For the most part we are unaware of these adjustments because our conscious mind is not designed to handle that much detail.  But even though we don’t hear the music, the dance goes on.

 The music of this dance is what the LSA Pro listens to, particularly the music of GSR. But instead of presenting the body with actual stressors, the LSA Pro generates virtual stressors, queries.  In this manner the body can be presented with a large number of simulated challenges, or questions, and by listening to the biotelemetry reflected in GSR the LSA Pro receives the body’s answers.  It’s a stimulus-response experience.


While a healthy, balanced body has the capacity to deal with all stressors, an overtaxed or overstressed system eventually experiences difficulty in pushing back. The results of this can be fatigue, pain, weight gain, and susceptibility to illness. At this point, clinical intervention can support the body and help it restore balance.

The question is, "What options will best help the patient regain balance." There is no one-size-fits-all answer. Because every body is unique, the best solution for Jane may not work well for Sally, even though their general symptoms are the same. But the LSA Pro, employing patent pending techniques gives the practitioner the opportunity to inquire directly and tailor an approach fitted to the patient. The process is quick, clinically proven, and compelling for the patient, which improves patient compliance and increases the probability for greater clinical success.
