Probiotics are a type of “good” bacteria that occurs naturally in the body. However, some may find that taking probiotic supplements may provide health benefits, particularly for supporting the immune and digestive systems.

A probiotic is a type of live microorganism containing bacteria or yeast. Probiotics are naturally present in the digestive system. A person can also find probiotics in supplements, yogurts, other fermented foods, and beauty products.

The bacteria count in a probiotic product is measurable with the unit CFU and in billions, which stands for “colony-forming unit.” Some people may benefit from a probiotic with a higher CFU count.

There are a variety of strains of bacteria that count as probiotics, but the most common strains include lactobacillus and bifidobacterium.

The bacteria present in probiotics can help with digestion, producing vitamins, and destroying disease-causing cells. Probiotics may help regulate the digestive and immune systems.

Research from 2020 states that probiotics may help reduce constipation. Probiotics may also help reduce antibiotic-associated diarrhea and symptoms of ulcerative colitis and help treat gum diseases.

A 2020 review states that probiotics may be beneficial for:

  • digestive health
  • food allergies
  • brain function
  • inflammation
