PABA The Sun Protector
PABA may be the vitamin with the most unpronounceable name (para-aminobenzoic acid), so we generally refer to it only by its acronym. PABA, along with choline and inositol, are part of the vitamin-b complex family but are unique because they are produced in the body so they’re not considered essential vitamins. Although they are not essential, they are involved in many important body processes.
PABA is mainly known as an active ingredient in sunscreens as it helps protect against UV rays of the sun. In addition to being a common ingredient in sunscreens, PABA has vital roles within the body. It increases the use of protein within the body and appears necessary for the body’s formation of folic acid. It also aids in the formation of blood cells and has been linked to combating gray hair, although this effect has not been proven in clinical studies.
Food Sources Liver, kidney, grains, mushrooms, molasses and spinach.
Recommended Dosage The Reference Daily Intake (RDI) for this nutrient has not been established, but a wide range (50 500 mg) is considered a therapeutic range.
Supplements Generally supplemented in doses of 25-50 mg Combines well with folic acid and vitamin C.
Side Effects & Toxicity Very high levels can cause nausea, skin rashes and vomiting. Liver toxicity is also present at very high levels. The toxic level of PABA is very high, therefore toxicity should not be an issue for most people.
Symptoms of Deficiency Symptoms of PABA deficiency include irritability, depression, nervousness, constipation, eczema, and skin blemishes.
