Withanolides are a class of naturally occurring, biologically active steroidal lactone compounds. They are the characteristic active ingredients and primary source of efficacy in the Withania somnifera plant. Withania somnifera, more commonly known as Indian ginseng, shares a chemical structure with ginsenosides found in ginseng. This unique structure enables them to interact with multiple physiological systems within the human body.
The most important withanolides in Withania somnifera extracts include withaferin A, withanolide D, and withanolide A. High-quality Withania somnifera extracts are typically standardized to a withanolide content (e.g., 2.5% or 5%) to ensure consistent efficacy.

Our packing method is 1KG/Aluminium bags, 25kg/drum
For some products that require special packaging during transportation, we will carry out more delicate packaging. For example, retinal needs to be stored at -20 °C, so we choose cold chain transportation during transportation; deoxyarbutin will change color during transportation, so we will Vacuum packing of deoxyarbutin
