What is “Marine Plasma”?

Marine Plasma, or more specifically Quinton marine Plasma (QMP) is an enriched mineral sea water with trace elements and biologically active substances. The purification procedures of and cold sterilization of QMP ensures that it does loss of its medicinal properties. QMP has been used is successfully in the prevention of numerous disease, improvement in immune system and cognitive function[i][ii]

Dr. René Quinton was a French physiologist and biologist who made significant contributions to the understanding of marine plasma and its potential therapeutic applications[iii][iv]. In the late 19th and early 20th centuries, Dr. Quinton conducted research that led to the development of a theory known as “marine therapy” or “Quinton therapy.[v]

Dr. Quinton’s work focused on the similarities between the composition of seawater and the internal fluids of living organisms, particularly blood plasma. He believed that the properties of seawater closely resembled those of the internal fluids in various marine species, and he hypothesized that using diluted and sterilized seawater could have therapeutic benefits for human health. Dr. Quinton successfully used his marine plasma as a healing agent on thousands of patients in France and Egypt in the early 1900’s[vi]. By 1906, 69 Quinton Dispensaries had been established and had successfully treated thousands of patients that were epidemic at that time. This included Influenza, Cholera, Tuberculosis, Syphilis and Typhoid[vii].

In the context of marine plasma, Dr. Quinton observed that the composition of seawater was remarkably similar to the composition of blood plasma in vertebrates. Blood plasma is the liquid component of blood that carries cells, nutrients, hormones, and waste products throughout the body. It plays a vital role in maintaining the osmotic balance[viii], pH, and overall homeostasis within the body.

Dr. Quinton’s observations led to the development of Quinton’s Marine Plasma, a solution derived from seawater. This solution was isotonic with blood plasma, meaning it had a similar concentration of salts and minerals. Quinton believed that introducing this isotonic marine plasma into the human body could support cellular functions and contribute to overall health.

The link between plankton and marine plasma lies in the nutrient cycling and composition of seawater. Plankton, particularly phytoplankton, is a primary producer in the marine ecosystem. These microscopic organisms perform photosynthesis, converting carbon dioxide into organic compounds and releasing oxygen. Zooplankton, in turn, consumes phytoplankton[ix].

Marine organisms, which marine plasma has been shown to have an overwhelming abundance of them, is a valuable source for biologically active compounds[x]. It is a liquid derived from marine sources, typically seawater and is also a rich source of minerals. The concentration of these elements can vary depending on the specific location and environmental conditions. This term is often associated with products that claim to harness the benefits of the minerals and trace elements found in seawater for various health and wellness purposes, which have been shown overcome health problems especially related to lifestyle-associated diseases[xi].  It has been shown to have identical ionic balance to that of blood serum and interstitial fluid[xii], and contains the full spectrum of minerals and trace elements found in human plasma such as potassium, calcium, and magnesium [xiii][xiv][xv].

What is “Structured Living Marine Plasma”? “Structured living marine plasma” is also derived from marine sources, such as seawater. The term “structured” implies that the plasma has been processed or treated to enhance its bioavailability or stability, which can occur when it is harvested from specific plankton blooms at specific locations.  It is collected from phytoplankton vortexes and subsequently diluted with spring water, which has very low mineralization.

The composition of marine plasma includes a variety of minerals, such as sodium, magnesium, potassium, calcium, and trace elements like iodine, selenium, zinc, and a host of other trace minerals. It is basically the liquefied form Hand Harvested French Celtic Sea Salt in  composition of pure sea water produced in specific areas of the ocean from plankton blooms.

Studies have shown that marine plasma products with this minerals composition in a balanced form, which has a similar to the composition of human blood, can contribute to overall health. While specific claims may vary, here are some general potential health benefits associated with marine plasma.

Immune System Support[xvi]: Trace elements present in marine plasma may contribute to immune system function, supporting the body’s defense against infections. It appears to support mucin glycoprotein function which are the major constituents of mucus which lines epithelial surface of the respiratory tract including the nasal cavity system nasal cavity, larynx, trachea and bronchi tree and provides an important innate immune function by trapping and removing particles and pathogens from the airways[xvii].
