Urolithin A is a natural metabolite of ellagitannins found in pomegranates and nuts. In the human body, it is a special substance metabolized from intestinal microorganisms.
The production process of urolithin A includes fermentation process and chemical synthesis process. Currently, large-scale production of urolithin A raw materials is mainly based on chemical synthesis processes.
In terms of structure, it is the same as the compound formed endogenously after ellagitannins and ellagic acid.
The color of urolithin A powder varies from light yellow, yellow to white and grayish white.
