PABA (para-aminobenzoic acid) is a small organic compound found naturally in foods like liver, eggs, and whole grains, and produced in small amounts by gut bacteria. It was once labeled 'Vitamin Bx' because early researchers thought it was essential, though we now know the body doesn't require it from diet in the way true vitamins do. It has a long history of use in dermatology and connective tissue health. PABA appears to work in two main ways: topically, it absorbs UV light and protects the skin from sun damage; internally, it may help soften and break down fibrous tissue buildup by influencing the balance of proteins that regulate tissue formation. It also plays a role in supporting folic acid activity in gut bacteria and may support melanin production in hair follicles. Available as oral capsules and tablets (typically 100–500 mg), topical creams and sunscreens, and bulk powder. The prescription form Potaba (potassium para-aminobenzoate) has been used in clinical settings at much higher doses (12 g/day) for connective tissue disorders.

Quick Facts

• What it is: PABA is a naturally occurring compound found in small amounts in certain foods and in the human body, historically grouped with B vitamins though not a true essential vitamin.
• Main uses: Used to support skin health, treat certain connective tissue disorders, and historically associated with hair pigmentation support.
• Best for: Skin conditions (Peyronie's disease, scleroderma), Hair health, Sun protection (topical)
• Active ingredients: Para-aminobenzoic acid (PABA)
• Forms: Capsule, Tablet, Topical cream, Powder
• Time to effect: Several weeks to months depending on the condition

Beef liver — One of the richest dietary sources of PABA, also supplying B vitamins that work alongside it
Eggs — Contain measurable PABA along with protein and folate that support similar pathways
Whole grains (wheat germ, bran) — Whole grain products contain small amounts of PABA along with B vitamins
Spinach and leafy greens — Provide PABA alongside folate, which works closely with PABA in cellular metabolism
Molasses (blackstrap) — Traditional source associated with B-vitamin and PABA content, historically linked to hair health claims

Interactions

These are some possible interactions. Please consult with your doctor.

No interactions information available

Nausea and stomach upset (more common at high doses)
Loss of appetite
Skin rash or allergic contact dermatitis (topical use)
Mild liver enzyme elevation with prolonged high-dose use
Hypoglycemia reported rarely at very high doses
Fever (rare, with high-dose Potaba therapy)

Recommended daily: 100–400 mg/day for general supplementation; 8,000–12,000 mg/day (as prescription Potaba) for fibrotic conditions under medical supervision only
Best time of day: Divided doses throughout the day are preferred to reduce stomach upset
With or without food: Take with food to minimize nausea, especially at higher doses
Time to effect: 4–6 weeks for general use; 3–6 months for fibrotic conditions
How long to take it: Short-term or ongoing use is fine at low doses; high-dose Potaba therapy for fibrotic conditions should be medically supervised and typically continues for several months — do not self-medicate at those levels

This app is so cool! I've always wanted there to be a hub for all NATURAL remedies and preventative options but l've always had to do loads of digging to find the info I wanted for different natural products. HealisticMD has all the info I need in one place. It gave me various natural supplemental options for a condition I looked up, including what each remedy does and how much is usually recommended to take. It also gave me exact products I could buy for the problem I had looked up. It makes my process SO MUCH easier when I need to find non-pharmaceutical solutions to my needs.

There is a wealth of information on the app! I recently had bloodwork done and found I was deficient in a handful of vitamins and minerals (Vitamin B12, Vitamin D, Iron, etc.) HealisticMD made it simple for me to find out what foods to eat/ supplements I needed to improve these deficiencies. It gives you so many ideas on prevention, natural health tips, where to buy the vitamins, when to take them, why, etc. I love how easy the app is to use too. I am currently working on getting pregnant. I was pleasantly surprised to find compelling data along with supplement suggestions to aid in the process, some of which my fertility doctor wasn’t even aware of. Highly recommend downloading, after all health is one our greatest gifts!
