**13. Synbiotics**

Synbiotics are the combined products of both probiotics and prebiotics. The advantage of the combination of beneficial bacteria is the encouragement of beneficial bacterial growth. Synbiotics are produced by combinations of *lactobacillus* GG and inulins, *bifidobacteria* and fructooligosaccharides (FOS), and bifidobacteria and lactobacilli with FOS or inulins.

#### **13.1 Sources**

As symbiotics are the combined products of prebiotics and probiotics, so the sources of symbiotics are the same as probiotics and prebiotics. However, this combination is produced commercially.

#### **13.2 Function**

Evidence suggested that symbiotics can reduce sepsis, lower respiratory tract infection, and mortality among low-birth-weight infants [105].
