Despite the abundance of mineral nutrients in the ocean, the concentration of essential vitamins, particularly B vitamins, is extremely low in seawater, often at picomolar levels. This scarcity makes vitamins a limiting factor for the growth of many marine organisms, revealing a complex and delicate balance in the aquatic ecosystem.

With an average salinity of about 3.5%, ocean water is primarily known for its saltiness, yet a different question often arises: is ocean water sugar free? While the familiar taste of table sugar (sucrose) is absent, the ocean's chemistry is far more complex, including the presence of other organic materials.
