PABA is a micronutrient, sometimes referred to as vitamin Bx, though not a vitamin per se because it is not considered essential to human health and it can be produced in the body from folic acid.
PABA assists in forming red blood cells (erythrocytes), improves the body's use of protein, and promotes the production of folic acid by intestinal bacteria. It is also known to have beneficial effects on hair. PABA works best in concert with vitamin C and is considered a member of the vitamin B complex, though again, not strictly a vitamin itself. PABA is, however, a potent antioxidant.
Taking sulfa drugs may cause PABA dysregulation. This deficiency may manifest as fatigue, irritability, depression and constipation. It can also cause weeping eczema and patchy skin.
Food sources of PABA include rice, eggs, molasses, wheat germ and brewer's yeast.
