The paper presents information about the concept of vitamins and possible sources of vitamins from marine algae found in the Black Sea. The existence of vitamins in green algae from Enteromorpha and Cladophora species were identified through spectral analyzes in IR. Keywords: vitamin, marine algae, Enteromorpha, Cladophora, Black Sea 1. Introduction Modern research from the last years show that some vitamins have changed in their role of maintaining a healthy life. That’s why, in recent studies, the importance of vitamins has been highlighted in different diseases such as: (atherosclerosis, diabetes, Alzheimer disease, degenerative diseases etc). There were also researches on the antioxidant capacity of some vitamins (A, C, E). In addition there are numerous studies about the vitamin doses needed to maintain the homeostatic balance in the human body, that’s why vitaminology is a dynamic field in a continuous change [1]. The importance of maintaining a healthy diet has been acknowledged before the identification of vitamins. The ancient Egyptians knew that feeding a patient with liver, will help him with eyesight diseases, now this is known to be caused by vitamin A deficiency. In 1747 the Scottish surgeon James Lind discovered that citrus prevents scurvy, a lethal disease, which manifests in teeth bleedings and acute pain. In 1753 Lind published “A treaty on Scurvy”. Nevertheless his discovery hasn’t been accepted unanimously. For example in Royal Marine expeditions, it’s been thought that scurvy could be prevented by a good hygiene on the ship, by regular exercises and by maintaining a high morale of the crew instead of a fresh diet based on citric.
