Human Milk Oligosaccharides(HMOs)
Human milk oligosaccharides (HMOs) are the third largest solid component in breast milk and the largest active nutrient. Currently, more than 200 HMOs have been identified. Since oligosaccharides chains can be fucosylated or sialylated, they are usually divided into three categories:
(a)Fucosylated neutral HMO(35-50%)
(b)Nonfucosylated neutral HMO (42-55%)
(c)Sialylated HMO (12-14%)
Representative compounds of fucosylated neutral HMO——2'-Fucosyllactose(2'-FL)
The most abundant oligosaccharides in natural breast milk, about 30% of HMOs
The first HMO to pass the U.S. FDA safety assessment, with the most abundant scientific papers and clinical trials
Has irreplaceable physiological effects, covering three key functions: Intestinal, immunity and brain

Synaura HMOs Product Advantages
First Chinese company with dual certification from China and the U.S.
——China's first 2'-fucosyllactose (2-FL) product approved by both the Chinese National Health Commission and the U.S. FDA GRAS certification
The first company to obtain 99% high purity certification worldwide
——Certificated by authoritative third-party testing agencies, Synaura HMO sample can reach 99% purity and is structurally identical to the HMO extracted from Chinese breast milk*
Global leading patents layout
——A total of 50+ domestic and international patent applications, with 30+ patents granted to date. Patents
covering HMO strain development, process optimization, testing, and application, establish an independent
original research and development patent system.
