Our stomach, or gut, is full of bacteria. This bacteria correlates with our health and well-being. It is referred to as your microbiome. Probiotics are live microorganisms that help maintain a healthy community of bacteria. Having a healthy microbiome helps you digest food better, regulates your immune system, improves the quality of your skin, and your mood. They can also help with conditions such as IBS (Irritable bowel syndrome). Probiotics are mainly found in yogurt, fermented foods, or dietary supplements.

There are different types of probiotics. The most common bacteria belong to the group "Lactobacillus" and "Bifidobacterium". There is also Saccharomyces, Streptococcus, Enterococcus, Escherichia, and Bacillus.

Prebiotics are what probiotics feed off of. They are usually complex carbohydrates. This is why it is smart to take a supplement that has both probiotics and probiotics. 

Here are my favorite affordable probiotic+prebiotic supplements.
