PABA (Para-Aminobenzoic Acid): The Colorful Helper for Skin, Hair, and More!
PABA, also known as para-aminobenzoic acid or sometimes vitamin B10, is a fascinating nutrient that’s been used for decades in skin and hair care, as well as in some medical treatments. While it’s not officially a vitamin for humans, it plays several interesting roles in the body—especially for families interested in supplements and children’s health.
What Does PABA Do?
-
Supports Skin Health: PABA is best known for its history as a sunscreen ingredient, thanks to its ability to absorb UVB rays. While it’s less common in sunscreens today due to allergy risks, it’s still found in some lotions and creams for skin health.
-
May Help Hair Pigmentation: Some studies suggest PABA can help restore color to graying hair when taken as a supplement, though the effect reverses if you stop taking it.
-
Aids Digestion: PABA supports healthy gut bacteria, which in turn help produce folic acid—an essential B vitamin for growth and red blood cell formation.
-
Red Blood Cell Formation: PABA works with other B vitamins to help the body make healthy red blood cells.
-
Potential for Skin Disorders: PABA has been studied for conditions like scleroderma (skin hardening) and Peyronie’s disease, but scientific results are mixed and more research is needed.
How Does PABA Work?
PABA acts as a coenzyme in the body, helping with protein metabolism and supporting intestinal bacteria. These bacteria use PABA to make folic acid, which is vital for DNA, growth, and healthy blood.
Dietary Sources of PABA
While your body doesn’t make PABA directly, you can get it from a variety of foods and from the healthy bacteria in your gut.

PABA in Supplements
PABA is available as a supplement, sometimes combined with other B vitamins, folic acid, or vitamin C. It’s most often marketed for skin and hair health, or for supporting digestion.
| Supplement Form | Common Use | Notes |

Fun Facts and Quick Tips
-
PABA was one of the first active ingredients in sunscreens, but is now less common due to allergy concerns.
-
It works synergistically with other B vitamins and vitamin C for overall health.
-
Deficiency is rare, but can happen with long-term antibiotic use or digestive disorders.
-
Signs of low PABA might include skin issues, constipation, fatigue, or even premature graying of hair.
Should Kids Take PABA Supplements?
Most children get enough PABA from food and healthy gut bacteria. Supplements are rarely needed unless recommended by a healthcare provider for specific skin or digestive issues. Always talk to your pediatrician before starting any supplement.
In a nutshell:
PABA is a unique nutrient with a colorful history in skin and hair health. While it’s not an essential vitamin for humans, it plays a supporting role in digestion, red blood cell formation, and possibly maintaining youthful hair and skin. With a balanced diet rich in whole grains, veggies, and legumes, your child is likely getting all the PABA they need for healthy growth and development!
