Probiotics are the good bacteria that exists in your gut. In an oral form it is best to take them via a method that will protect the integrity of the bacteria. Probiotics that come in capsules tend to do this the best; in order to make tablets & gummies probiotics need to undergo a method called compression, which will kill off many of the probiotics. When placed in gummies, the heat required to make the product kills off even more probiotics.

Although probiotics that come in powder form avoids this, it exposes your probiotics to oxygen which decreases the freshness of the product.
