Intestinal Microbiota: Immunity, Recovery and Metabolic Health

Intestinal Microbiota: Immunity, Recovery and Metabolic Health

The aim of this intervention study is to investigate the effect of a specific postbiotic (Lacticaseibacillus rhamnosus GG = LGG) and whey protein on immunity, recovery, and weight management in young adults. The objective is based on previous knowledge about the health-promoting effects of these factors. A new goal is to study the combined effect of the postbiotic and whey protein. The results of the study can be utilized to promote the health of the young adults.

The study is a randomized, double-blind, 3-arm intervention involving young adults (n=160). Participants are randomized into three groups to receive different study product, and differences among the groups will be compared, for example, in terms of gut microbiota, weight changes, and inflammatory markers derived from blood samples.
