Among the B complex vitamins, vitamin B7 forms an essential constituent of human nutrition. Vitamin B7 benefits are manifold and primarily include its role as a coenzyme in biosynthesis of fatty acids, urea, purine nucleotides, and carbamyl phosphate (related to skin health).
Deficiency of vitamin B7 results in impaired metabolism of carbohydrates and proteins and reduced cognitive functions.
Sources of vitamin B7 constitute yeast, egg yolk, nuts, vegetables such as cauliflower and peas, and organ meats like liver and kidney. Consumption of raw egg white is often linked with a deficiency of vitamin B7, as it is known to contain a chemical called avid that interferes with vitamin B7 absorption.
A common sign of vitamin B7 deficiency is skin disorders such as dermatitis, eczema, and seborrhoea. Increased prevalence of dandruff, skin pallor, and hair loss is also among the common signs.
Deficiency of vitamin B7 causes muscular weakness, lethargy, lowered appetite, and anaemia.
Signs of deficiency of vitamin B7 also include neurological symptoms such as depression, drowsiness, and mental confusion.
