What is Para-Aminobenzoic Acid (PABA)?

Para-aminobenzoic acid, more popularly known as PABA, is a non-protein amino acid largely available in nature.

Also known as 4-aminobenzoic acid, it can be found in food sources such as liver, eggs, molasses, rice, wheat germ and spinach.

PABA is widely used as an ingredient in topical sunscreen since it has the ability to absorb ultraviolet rays. Aside from providing protection from sunlight, PABA plays other important roles in the body.

Para-aminobenzoic acid (PABA), a component of pteroylglutamate, was once considered a vitamin because it serves as a provitamin for some bacteria. Later studies showed that it does not possess vitamin activity because humans lack the ability to manufacture folate using PABA. However, PABA is biosynthesized in humans by intestinal bacteria and appears necessary in metabolism.

PABA is often referred to as Vitamin Bx (part of the Vitamin B complex family), but it is neither an actual vitamin nor an essential nutrient. The para-aminobenzoic makeup of PABA does make it a vitamin B complex factor and a folacin constituent.

Health Benefits of Para-AminoBenzoic Acid (PABA)

PABA is classified as an antioxidant, which protect cell membranes from the damage caused by free radical compounds in the body created by oxidative stress. PABA also helps in the production of erythrocytes, or red blood cells, important in ensuring there is sufficient oxygen brought throughout the body.

PABA enhances the ability of the body to perform protein synthesis (Wikipedia), making it beneficial for those seeking to build muscles.

Purity and Concentration of Para-AminoBenzoic Acid (PABA)

This pharmaceutical-grade amino acid contains no fillers, taste additives or anti-caking agents.

Suggested Use of Para-AminoBenzoic Acid (PABA)

As a dietary supplement, take 100 milligrams (1/16 tsp) to 500 milligrams (rounded 1/4 tsp) daily, or as directed by physician. Individual needs vary. As you can see from the Volumetric Measures chart, of 1/16 tsp is about 100 milligrams. A serving of 1/4 tsp is equal to 440 milligrams, so a slightly rounded 1/4 tsp will give about 500 milligrams.

One point to keep in mind is that the body needs a supply of all the amino acids in order to effectively create and utilize proteins. Those supplementing any of the amino acids should have a balanced intake of all the other amino acids.

Potential Side Effects of Para-AminoBenzoic Acid (PABA)

PABA is generally safe at suggested serving sizes. Side effects that have been reported are relatively minor and include upset stomach, loss of appetite and nausea. Allergic reactions which include rash, swelling, itching, severe dizziness and breathing problems have been reported in a few patients. Recent studies have shown that daily intake of 8 grams or more can cause fever and malaise, and can lead to low blood sugar, skin irritations and liver damage. Extremely large quantities (20 grams or more per day) are potentially fatal in children.

PABA supplements should not be taken with antibiotics in the sulfa drug category. People with liver or kidney disease should not take this or any other amino acid supplement without first consulting their physician. Getting too much of any one amino acid can throw the citric acid cycle out of balance, which makes the liver and kidneys work harder to eliminate toxins.
