GlyCare™ 2FL/DFL will be available as a mix of 2'FL and DFL in a ratio close to the composition naturally found in breast milk (1).
2'FL (2'fucosyllactose) is the most abundant fucosylated Human Milk Oligosaccharide (HMO) in human milk at ~2g/L. Clinical research describes that 2'FL is positively supporting the health of infants.
DFL (DiFucosyllactose or Lactodifucotetraose, LDFT) is a highly abundant fucosylated HMO in human milk. Emerging preclinical data suggests a potential role for DFL in gut health.
Preclinical studies suggest DFL may reduce the risk of pathogenic bacteria adhering to the intestinal cell wall (2,3,4). Additional preclinical data suggests DFL may also support gut health by selectively supporting the growth of beneficial bacteria such as bifidobacteria (5,6).
2FL/DFL has been approved as a Novel Food in Europe and regulatory filings have been made in the US. Preparation is on the way for other major markets.
GlyCare™ 2FL/DFL is available commercially.
