All about fruitarianism with a long-term fruitarian, Lena

Serum vitamin B12, serum folate and red blood cell folate levels were examined among 36 strict vegans of 5-35 years' duration.

Vitamin B12 levels among the vegans were generally lower than in a control population. Most of the vegans had vitamin B12 values less than 200 pg/ml

None of the vegans had any hematologic evidence of vitamin B12 deficiency, however four of them had neurologic complaints. Long-standing vegans should be monitored for vitamin B12 levels.

Red blood cell folate levels were normal but serum folate levels among the vegans were higher than among the controls. 

Charles Darwin

There is no fundamental difference between man and the higher animals in their mental faculties . . . The lower animals, like man, manifestly feel pleasure and pain, happiness, and misery.

Vitamin B3 Niacin

Vitamin B3, Niacin, nicotinic acid, helps to convert food into energy and is essential for healthy skin, blood cells, brain, and nervous system. It is one of 8 B vitamins. It is water-soluble, which means it is not stored in the body. It has 2 other forms, niacinamide (nicotinamide) and inositol hexanicotinate, which have different effects. 

Niacin occurs naturally in food and can also be made by your body from the amino acid tryptophan, with the help of B6

It is rare for anyone in the developed world to have a Vitamin B3 deficiency; alcoholism is the main cause of it in the US.
