Intestinal Influencers

The gut is the body’s second most important control center, after the brain. Alongside nerve and immune cells, it’s home to more than a thousand different species of bacteria. It’s all due to the community—the microbiome. Probiotics and synbiotics can positively influence the microbiome in many different ways

PROBIOTICS

How probiotic organisms support the body’s own bacteria

Intestine
1

Production of antimicrobial ­substances

These kill pathogenic bacteria or prevent them from multiplying

2

Competition for binding sites

Probiotics occupy sites and thus block pathogenic bacteria from binding

3

Improving the barrier

The spaces between the cells are more tightly sealed

4

Enzyme production

Enzymes help to break up nutrients. Intermediate products can be utilized by other intestinal bacteria

5

Production of lactic acid (lactate)

The lactate inhibits the growth of pathogens

6

Crossfeeding

Microbiota take up lactate and convert it into butyric acid (butyrate)

THE IMMUNE RESPONSE OF THE INTESTINE

How the intestinal barrier recognizes dangerous intruders and renders them harmless

Intestine
1

Dendritic cells and other phagocytes

ingest foreign micro­organisms and present the microorganism’s antigens on their cell surfaces. They activate and control the responses of the immune system

2

Plasma cells

are B-lymphocytes and produce large quantities of antibodies (immunoglobulin A), which fight off foreign microorganisms

3

M cells

are specialized epithelial cells that enable the recognition of antigens from the intestine. The antigens are passed on to immune cells, which then move into the lymphatic tissue of the intestine and initiate immune reactions

4

Goblet cells

secrete mucus (mucins) that protects the intestinal absorptive cells against mechanical irritation and contact with intestinal bacteria

5

Paneth cells

These gland cells produce peptides for suppressing pathogenic microorganisms

SYNBIOTICS

How combinations of probiotics with additional ingredients can boost the production of certain substances by bacteria

1

Butyrate production

Bacillus subtilis and the dipeptide alanyl-glutamine (Ala-Gln) work together to increase the production of butyrate, which is an important source of energy for intestinal cells

2

Resolvin production

Bacillus megaterium converts high doses of omega-3 fatty acids into resolvins that can inhibit inflammation

The microbiome

Health begins in the gut

In good company: The microbiome consists of countless bacteria that are crucial for our health.
