Vitamin B10 (PABA - Para-aminobenzoic Acid)

Health Benefits of PABA

• Skin Health: Known for its role in protecting the skin from UV radiation and preventing sunburn when used in topical formulations.
• Hair Health: May contribute to maintaining natural hair color and preventing premature graying, although more research is needed to confirm these effects.
• Supports Folic Acid Synthesis: Acts as a precursor in the synthesis of folic acid by gut bacteria, aiding in overall folate metabolism.
• Antioxidant Properties: Helps reduce oxidative stress and protect cells from free radical damage.

Interaction with Other Vitamins and Minerals

Key Interactions

• Folic Acid (Vitamin B9): Works closely with folic acid as part of its synthesis process in the body, supporting DNA and cell growth.
• Vitamin B Complex: Functions synergistically with other B vitamins to support metabolic and cellular functions.
• Biotin (Vitamin B7): High doses of PABA may interfere with biotin absorption, so balanced intake is essential.
• Iron: May enhance the utilization of iron by improving folate metabolism, which is important for red blood cell production.

Potential Effects of Imbalances

• Deficiency Issues: Not classified as an essential nutrient for humans, so true deficiencies are not common. However, insufficient levels may potentially impact skin health.
• Excess Intake: High doses of PABA can lead to side effects such as nausea, vomiting, and, in rare cases, liver toxicity or kidney damage.

Conclusion

While once considered part of the vitamin B complex, PABA (Para-aminobenzoic Acid) is no longer classified as an essential vitamin. It is valued for its benefits in skin protection and potential roles in folate synthesis, but supplementation should be approached with caution.
