1. Product Introduction
Lemairamin WGX-50 (Xanthoxylin Lemairamin) is a characteristic natural active compound extracted and purified from Zanthoxylum bungeanum. It is exclusively derived from Zanthoxylum plants and widely distributed in Chinese and Asian wild pepper resources. With unique pharmacological and physiological activities, WGX-50 stands out among plant-derived active ingredients, integrating anti-aging, antioxidant, anti-inflammatory, antibacterial and metabolic regulation functions.
Different from ordinary pepper extracts, high-purity Lemairamin WGX-50 has definite anti-aging and anti-AD pharmacological activity. It effectively promotes cellular collagen synthesis and scavenges excess ROS free radicals, achieving dual skin anti-oxidation and anti-aging effects. Meanwhile, it retains the traditional medicinal values of Zanthoxylum plants, including gastrointestinal regulation, analgesic and vascular circulation improvement. Our factory supports full-process OEM/ODM customization, with independent aseptic production workshops and finished product processing lines to customize capsules, tablets and powder filling services for global customers.
Lemairamin powder wgx-50 refers to a class of compounds found in Zanthoxylum plants. It is a natural product widely distributed in Zanthoxylum bungeanum plants in China and other Asian countries.
The pharmacological characteristics of WGX50 are anti-aging. On the one hand, it can promote the production of collagen in cells and inhibit the production of reactive oxygen free radicals ROS, thereby showing anti-aging and antioxidant effects. On the other hand, WGX50 also has anti-AD pharmacological activity.
We offer customized services like OEM and ODM. We have an aseptic production workshop as well as a final product processing workshop where we can create custom tablets, capsules, and fill powder.
