Vitamin B10, better known as PABA (para-aminobenzoic acid), is a water-soluble vitamin and a member of the B-complex family.

PABA is a component of Vitamin B9 (folic acid) and is required for the body to absorb Vitamin B5 (pantothenic acid).  And you now know the importance of the B Vitamins!

Most research surrounding PABA mainly focuses on its ability to improve connective tissue disorders such as scleroderma. It has also been shown to be effective in reducing inflammation associated with arthritis.
