Uniqueness of Ocean Plasma (1) Sea water is extracted from the phytoplankton bloom vortex 35 miles off Nova Scotia (where three streams meet) located exactly 30 meters from the surface and 10 meters from the ocean bed, the zone of Solar Penetration which is known for its exceptional purity and rich in nutrient. (2) Using a Proprietary process, Ocean Plasma follows the same protocol laid down by Rene Quinton over 100 years ago i.e. never exposed to heat, radiation, UV light, or contact with metal during the course of manufacture; with triple cold filtration and tested in a manner that protects it from alteration and preserves its state as a living water. (3) It contains a wealth of natural organic minerals and trace elements (electrolytes) around 92; that as a group, even though many are in minute amounts, helps the body to re-mineralized, purify and regenerate the extra cellular fluid. (4) These minerals and electrolytes are in organic ionic form, is the form required to pass through the membrane of every one of the 60 trillion bodily cells. All cells draw their nourishment from the extra cellular fluid. (5) The composition of the minerals and electrolytes in Ocean Plasma are in the proper ratios needed by human tissue and has an almost identical composition with our extra cellular fluids. (blood plasma, amniotic fluid, lymph etc). (6) The isotonic Ocean Plasma has been diluted with spring water yielding a mineral salt concentration of 9ppt (9000ppm) – the salinity of human blood. (7) Both Ocean Plasma and blood plasma have inherent homeostatic mechanism that ensures a constant Ph. When chronic acidification occurs in our blood, the body robs calcium, magnesium and other highly charged electrolytes from our bones and tissues in order to stabilize the pH of our blood. Ocean Plasma Ph matches that of our blood i.e. 7.4 to 7.6. (8) Ocean Plasma is one of the best approaches to prevent infections and other health problems. Drinking Ocean Plasma is easy once we get into the habit of drinking it every day as it is safe with no side effect. (9) Ocean Plasma not only nourishes the body but also helps to detoxify the body. (10) Ocean Plasma comes in 30ml PET1 bottle which is better than ampoule as once open it can be kept in a fridge for later consumption. PET1 is hygienic, strong, resistant to attack by micro-organisms, does not react with foods or beverages, and will not biologically degrade. Its safety for food and beverage use is recognized by health authorities around the world. But unlike glass, PET is extremely lightweight, simple to transport and won't break, which is why it is highly recommended by the FDA. I Box Contain 30 Bottles Of 30c.C.Per Bottle.
