Para-aminobenzoic acid or PABA is a chemical substance that is part of folic acid. Though PABA naturally occurs in the human body, it is synthesized by the gut bacteria E. coli. PABA is required for the proper functioning of several enzymes in the body especially those involved in metabolic and digestive processes.

PABA can also be got from several food sources including green leafy vegetables, organ meat, whole grains, mushrooms, milk, and eggs.

PABA as a supplement

Though a PABA deficiency is rare, PABA supplements can be used to treat a number of other conditions. Taken orally, PABA supplements have been used to treat skin conditions like:
  • Vitiligo
  • Pemphigus
  • Morphea
  • Scleroderma
  • Dermatomyositis<
  • Lymphoblastoma cutis
  • Peyronie's disease
    • Besides healthy skin, PABA supplements have also been used to maintain healthy hair. PABA has been found to stimulate hair growth, reduce hair fall and decrease the greying of hair. Other uses of the PABA supplement include treatment of some types of anemia, arthritis, rheumatic fever, and infertility in women.

      The best-known use of PABA is as an active ingredient in sunscreen. PABA can block UV rays and is therefore used in topically applied sunscreens.

      PABA deficiency

      PABA deficiency might occur in individuals who have undergone prolonged antibiotic treatment. Antibiotics can destroy gut bacteria which in turn affects PABA synthesis in the body. If the PABA requirement is not met through the patient's diet, a supplement can be administered.


      When used in the treatment of Peyronie's disease PABA is usually given in four doses of 3mg each daily with food. When added to sunscreen, the percentage of PABA is usually between one to fifteen percent.

      PABA Side effects

      PABA has been found to be safe for use when applied with sunscreen or when taken in the recommended doses. There have been no known side effects within the prescribed limits. However, an overdose of PABA can have side effects. These side effects include blood disorders, kidney disease, and liver disease. The upper limit set for PABA taken orally is 12 grams a day.

      PABA is not recommended for pregnant and breastfeeding mothers as the effects on unborn and very young children is not fully understood. PABA is also not recommended for people suffering from kidney disease as it could make the condition worse.

      PABA can interact with certain antibiotics like Sulfonamide antibiotics and Dapsone decreasing their effectiveness in treating an infection. PABA supplements are not to be taken along with any of these medications.
