PABA - Benefits, Deficiency Symptoms And Food Sources

PABA (Para-aminobenzoic acid) is classified as a vitamin-like substance. In its para-aminobenzoil moiety it is a factor in the vitamin B-complex vitamins and a component of folacin. Bacteria are able to synthesize folic acid from PABA; therefore, for these organisms, it is considered a vitamin. Humans, however, cannot use aminobenzoic acid to synthesize folacin. PABA does perform certain metabolic functions in some animals.

Functions and benefits of Paba

The most well-known property of PABA is as an effective sunscreen, when used topically. Para-aminobenzoic acid is a chemical sunscreen which absorbs ultraviolet (UV) and visible sun light. As an antioxidant, PABA also provides protection against ozone, smoking, and other air pollutants which damage other cell structures and membranes through oxidative stress. Limiting exposure to the sun and using sunscreen agents can help prevent early wrinkling and skin cancer. PABA is important for healthy hair and skin, and taking it in supplement form may prevent hair loss by protecting hair follicles.

It is also effective in the treatment of vitiligo, a condition that causes discoloration of the skin. PABA has been reported to enhance the effects of cortisone. It may also prevent or even reverse accumulation of abnormal fibrous tissue.

Recommended Dosage for Paba

The usual dose of PABA is between 30 to 100 mg. three times a day. In addition to PABA, the potassium salt of PABA called POTABA is available on prescription. POTABA is indicated for Peyronie's Disease and scleroderma. The dose used for these disorders is 12 grams daily taken in four to six divided doses with meals. The dose for Peyronie's disease and scleroderma is high and must only be used under medical supervision.

Deficiency Symptoms of Paba

Deficiency problems are not very common; they occur more frequently with the use of sulfa or other antibiotics that alter the functioning of intestinal bacteria and, therefore, the production of PABA. General fatigue, irritability, depression, nervousness, graying hair, headache, and constipation or other digestive symptoms may occur.
