What are postbiotics?

In Japan, they are called Lactobacillus Fermented Extracts. Probiotics are good bacteria that reside in the human intestine and are vital to our health. Over the years, the Latest studies have already found that the major healthy effects of probiotics are from the functional metabolic secretions (postbiotics) secreted by good bacteria ,which including key nutrients such as short-chain fatty acids (SCFAs), small molecule peptides and functional protein. They effectively promote absorption disorders, thus induces various diseases including obesity, constipation, diarrhea, irritable bowel syndrome (IBS), and immune disorders

Dr. Mitsuoka, who is a world-renowned authority on intestinal bacteriology and has made significant contributions to the advancement of science in yogurt research, with notable accomplishments. said: 「乳酸菌の菌体成分や代謝物質が腸を刺激し、腸内フローラを改善することで「腸替免疫」を活性化させるのですから、代謝産物も重要な成分です。」

IBS Relief
“ Moreover, most studies found positive effects for the use of postbiotics on diverse primary outcomes, especially for gastrointestinal functioning and in the treatment of chronic diarrhea or diarrhea predominant IBS” (1)
Constipation Relief
“Subjective and objective Bristol stool scale scores, output and color tone were improved in the postbiotic group, especially in the subgroup of people with a tendency towards constipation.”(1)
Skin Severity Relief
“One study investigated the effect of postbiotic L. paracasei K71 versus a placebo in adults, aged 20–65, on atopic dermatitis. Skin severity scores were significantly improved after 8 and 12 weeks in the intervention group, but not in the placebo group.” (1)
Immunity boost
”The molecular mechanisms underlying the effects of postbiotics seem to be mediated through an interaction between the host and microbial products. This in turn can trigger the host immune system, and thereby trigger e.g., anti-inflammatory responses” (1)
