Curcumin is a yellow pigment extracted from the dried rhizome of turmeric. It is a natural plant polyphenol with a diketone structure. The dosage forms that our company can provide include powder, capsules, tablets, granules, soft candies and other products. Currently, there are water-soluble and oil-soluble products on the market.
Curcumin is mainly used in products such as food, medicine, and pet poultry feed.
Anti-inflammatory and antioxidant are its two main characteristics, and most related research focuses on these two aspects.
The phenolic hydroxyl groups in the curcumin structure can directly scavenge free radicals and also have anti-lipid peroxidation effects, which can protect the skin.
It can also resist oxidative damage caused by ultraviolet rays.
