Functions of Probiotics

Probiotics are “friendly” live bacteria and yeasts that line our digestive tract. 

As a whole, probiotics provide vital support for our overall health. Our bodies have a symbiotic relationship with these microorganisms, meaning they work together to survive. Probiotics promote immune health (as nearly 70% of our immune system is located in the digestive system), digestive health, brain health and emotional wellness. These good bacteria produce enzymes that help balance our digestive system and support our body’s ability to absorb nutrients.

The most populous bacteria in the small intestine are from the Lactobacillus species. They produce lactase and lactic acid, helping to break down nutrients and support digestion.

The lactobacilli strains, in particular, have been studied for their role in supporting and maintaining vaginal and urinary tract health. These strains may protect the urogenital tract by excreting biosurfactants that help keep vaginal tissues clean and healthy.

Like the Lactobacillus species, Bifidobacterium produce lactic acid and help maintain a healthy balance of gut flora. Strains in this species also support immune system function.

Yogurt, unpasteurized, fermented dairy products like kefir contain probiotics. Unpasteurized, fermented vegetables like kimchi and kombucha also contain probiotics.
