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.
