What Is PABA para-aminobenzoic acid Used For and What Are the Side Effects

What Is PABA Used For and What Are the Side Effects?

PABA, or para-aminobenzoic acid, is a natural substance found in some foods and is part of the B complex group. It is a precursor to folate and helps certain skin conditions.

PABA is found in some foods and is available as a supplement. While it is generally safe to take, topical products may cause reactions.

PABA stands for para-aminobenzoic acid. It is sometimes referred to as vitamin Bx or B10 and belongs to the B complex group, although it is not a vitamin. PABA is essential for plants, bacteria, and some animals, but not for humans.

PABA is present in foods like mushrooms, molasses, whole grains, liver, spinach, and Brewer’s yeast. It is also used in sunscreen, medications, and in the pulp and paper industry as a UV-protection coating.

PABA supplements can be found in pharmacies and health food stores. It is generally considered non-toxic, but side effects are known.

Health Benefits of PABA

PABA was once used for skin and hair care and as a treatment for certain diseases. However, the results of studies on its benefits are mixed.

Precursor for Folate

Vitamins are essential nutrients that the body needs but cannot produce in sufficient amounts. Folate, or vitamin B9, is one of these vitamins.

Folate is necessary for the production of DNA, RNA, proteins, healthy red blood cells, breaking down homocysteine, and the development of a healthy nervous system in unborn babies.

PABA is a precursor for folate. While bacteria in the gut produce PABA, it is not enough to meet the body’s needs. Folate or folic acid must be obtained from food.

PABA was previously used in sunscreens to absorb and break down UVB radiation, protecting the skin from its harmful effects.

However, PABA is photosensitive and allergenic, and it can cause rashes and sensitivity to sunlight. The government plans to classify PABA as not generally safe for sunscreens.

Possible Help for Skin Conditions

PABA is also used in the treatment of some autoimmune skin disorders, including scleroderma, dermatomyositis, and Peyronie’s disease. However, the effectiveness of PABA in treating these conditions is inconclusive.

Scleroderma is a condition that causes the skin to thicken and become tight due to the immune system’s incorrect response. PABA can help improve oxygen uptake by tissues, potentially reducing scarring. There are conflicting results from studies on its effects.

Peyronie’s disease causes scars under the skin of the penis, leading to curvature and difficulties with erections. While PABA might help in some cases, results vary and it may not reverse the condition.

Enhances Antibiotic Activity

Despite being an essential nutrient for bacteria, PABA has antibacterial properties. It can inhibit the growth of certain strains of bacteria, such as Listeria, Salmonella, and E. coli.

PABA can also enhance the efficacy of antibiotic medications against drug-resistant strains of Staph and Pseudomonas bacteria. However, its poor absorption limits its usefulness in treatments.

Temporary Re-pigmentation of Gray Hair

PABA has been used since 1941 to darken gray hair. Studies have shown that daily doses of 200 milligrams of PABA can lead to re-pigmentation of gray hair. However, the effects are temporary and the hair returns to its gray color after discontinuing PABA supplementation.

Side Effects of PABA

While PABA is generally non-toxic, it can cause allergic reactions and digestive issues. Rare side effects have also been reported.

Digestive Upset

PABA supplements can cause stomach upset, including nausea, vomiting, and diarrhea. Headaches have also been reported.

Rashes

Topical use of PABA in creams or sunscreens can cause itchy, red rashes. Large doses of PABA may also make the skin sensitive to sunlight, resulting in a rash.

Liver Injury

PABA has been linked to cases of liver injury in patients receiving treatment for Peyronie’s disease. However, patients recovered fully after discontinuing the medication.

Blocks CoQ10

PABA seems to interfere with Coenzyme Q10 (CoQ10) production, a substance used by cells for energy production and DNA protection. PABA treatment may cause a decrease in CoQ10 levels and an increase in free radical damage in mitochondria. However, more research is needed to determine the implications of this interference.

PABA Is Generally Safe

PABA is considered non-toxic and safe as a supplement. However, it is no longer used in sunscreens due to the potential for rashes and allergic reactions. Consult your doctor before using PABA for health purposes.
