Brief Introduction:

D-panthenol is also known as provitamin B5. Widely used in medicine, food, cosmetics and liquid preparations. D-panthenol can be converted into pantothenic acid when entering the human body, and then synthesize coenzyme A, promote the metabolism of protein, fat, and sugar in the human body, protect the skin and mucous membranes, improve the luster of hair, and prevent the occurrence of diseases.
