Introduction to Plant Material
The raw material of this product is the dried mature fruit of the Solanaceae plant Lycium barbarum L. (Ningxia Goji berry). It is mainly produced in Zhongning of Ningxia, Jingyuan in Gansu, Qinghai, and other regions, with Zhongning in Ningxia being known as the “Hometown of Goji in China.” It is recorded in Volume I of the 2020 edition of the Chinese Pharmacopoeia. Goji is a medicinal and edible homologous variety, with the effects of nourishing the liver and kidneys and enhancing essence and vision. Its main active component, Lycium barbarum polysaccharides (LBP), has significant immunomodulatory and antioxidant effects.
Core Efficacy
Goji (Lycium barbarum) is a medicinal and edible homologous superfood, traditionally used to nourish the liver and kidneys and improve essence and vision. Its characteristic component, Lycium barbarum polysaccharides (LBP, standardized polysaccharide 30%-50% in this product), has immunomodulatory and antioxidant activity and can enhance antioxidant enzyme expression through the Nrf2/HO-1 pathway; zeaxanthin di-palmitate has relatively high bioavailability in the body, and some clinical studies show it may help support macular pigment density and eye health. Relevant in vitro and animal experiments also suggest Goji potential in metabolic regulation. Specific effects need to be evaluated comprehensively based on form, dosage, and population.
