We’ll get the simple question out of the way first: what is a probiotic?
Probiotics refers to the good bacteria in your stomach.
Everyone knows that bad bacteria can cause illness and infection, but researchers are learning more and more about the full benefits of the good, beneficial bacteria that your body – and your gastrointestinal (GI) system in particular – needs to function at 100%.
Here are just a few of the jobs probiotics accomplish:
- Aid in the production of Vitamin K, folate, and certain B vitamins and short chain fatty acids
- Play a large role in your overall immune system (70-80% of your immune system is in your gut)
- Aid in the digestion of foods, ensuring breakdown and absorption of vitamins, minerals, fatty acids, and amino acids
- Improved mental clarity, focus, and memory
- Contribute to serotonin production (up to 95% of which comes from your gut!)
- Keep harmful microorganisms and bad bacteria in check
This last benefit is one of the most important.
When your GI tract has sufficient levels of probiotics, they essentially crowd out the bad bacteria (think along the lines of a competition for resources). When harmful bacteria are kept to a minimum, your immune system can do its job in preventing infections and disease.
Your mental health also benefits, as more recent studies are proving: serotonin levels and neurotransmitter function both rely heavily on your intestinal health. (1)
