PABA (para-aminobenzoic acid)

PABA (para-aminobenzoic acid) is a naturally occurring compound related to B vitamins, found in small amounts in foods like grains and eggs. It plays a role in the production of folate, an essential nutrient for DNA synthesis and cell growth in bacteria and humans. Historically, PABA was used in sunscreens to protect the skin from ultraviolet rays, but its effectiveness and safety are now debated, and it is less commonly included in modern formulations. While it is vital for bacteria, humans do not require PABA supplements, as our bodies obtain necessary nutrients through diet.
