All about fruitarianism with a long-term fruitarian, Lena

Substantial amounts of vitamin B12 were found in some edible algae (green and purple lavers, seaweed) and chlorella tablets. A study suggest that algal vitamin B12 is a bioavailable source for mammals.

Pseudovitamin B12 (an inactive corrinoid) predominated in the spirulina tablets, which are not suitable for use as a vitamin B12 source, especially for vegetarians. 

Albert Schweitzer

A man is ethical only when life, as such, is sacred to him, that of plants and animals as that of his fellow men, and when he devotes himself helpfully to all life that is in need of help. 

Protists

Protists - members of an informal grouping of diverse eukaryotic organisms that are not animals, plants or fungi, and are grouped together for convenience, like algae or invertebrates. Besides their relatively simple levels of organization, protists do not necessarily have much in common. 

Subdivisions of Protists

Protozoa the unicellular "animal-like" - Flagellata, Ciliophora, Amoeba, Sporozoans.

Protophyta the "plant-like" - mostly unicellular algae.

Molds the "fungus-like" - slime molds and water molds.
