Our blood plasma is much closer to the sea than you think.

Human blood plasma and seawater have a strikingly similar mineral composition. This resemblance led biologist René Quinton to develop the concept of "marine plasma," a solution of seawater diluted to match the saline concentration of human plasma. Isotonic marine plasma is obtained by diluting hypertonic seawater (salt concentration of approximately 35 g/L) with pure water until a concentration of 9 g/L is reached, equivalent to that of blood plasma.

This similarity in ionic composition promotes rapid absorption of nutrients, providing an unparalleled source of bio-available minerals essential for the optimal functioning of our cells.

Thus, although hypertonic seawater has a higher salt concentration than blood plasma, once diluted to become isotonic, it has a mineral composition very close to that of our plasma, facilitating its assimilation by the body.
