Para-aminobenzoic acid (PABA), formerly referred to as vitamin B10, is an organic compound naturally present in the body. It is no longer classed as an essential vitamin, since gut flora can produce it, but it plays a supporting cofactor role in the synthesis of vitamin B9 (folate), which is important for cell renewal. It occurs naturally in whole grains, legumes and some fermented foods, though dietary intake is often modest.

PABA has drawn growing interest in nutricosmetics, particularly in connection with maintaining thick, healthy-looking hair. Some observational research has explored a possible link between PABA and melanin metabolism, the pigment responsible for hair colour — this reflects an area of traditional and observational interest, not a guaranteed clinical effect. Beyond hair, PABA is indirectly involved in folate production, cellular renewal support and antioxidant protection, and is often combined with biotin, selenium or collagen peptides for a broader vitality and beauty routine.

Take 1 capsule of 500 mg per day, ideally with a meal to support digestive absorption. The bottle of 60 capsules covers 2 months at one capsule daily; a course of 2 to 3 months is suggested, particularly for those seeking ongoing hair support. PABA pairs well with bioactive vitamin B9, biotin (vitamin B8) and zinc for a complete beauty routine.

At the recommended dose (500 mg/day), pure PABA is generally very well tolerated; some sensitive individuals may experience mild digestive discomfort. Do not exceed the recommended daily dose. Food supplement — not a substitute for a varied, balanced diet and a healthy lifestyle. Pregnant women should favour a direct folate (vitamin B9) intake as medically advised. Consult a healthcare professional if on any treatment.

Which foods naturally contain PABA?

PABA is found in whole grains (wheat, oats, rye), legumes (beans, chickpeas) and some fermented foods such as yoghurt or sauerkraut, though dietary intake remains limited.

Can PABA be combined with other hair-support supplements?

Yes. PABA is often combined with biotin (vitamin B8), Dynveo zinc bisglycinate and marine collagen for a broader approach to hair density and shine. Ask our team at Herba Barona in Paris for advice.

Is PABA really a vitamin?

No, PABA is no longer classed as an essential vitamin since gut flora produces it, but it remains an important cofactor in vitamin B9 synthesis and retains recognised nutritional interest.
