The concept behind this is a good one. You combine probiotics, which are good for the health of one part of the digestive system, with digestive enzymes that help other parts function in a healthy way.So, this product can improve digestion, as well as populate the colon with good bacteria. It also contains a prebiotic to help the good bacteria grow.My only issue is that the enzymes aren't listed by strength, but by the order of their potency, which is annoying. Not knowing the strength of the enzymes in the formula means you don't know what you are getting. Amylase and proteases are the first ingredients, so I am guessing this formula would be especially good to digest starch and protein.I originally gave this product a lower rating because I got an expired product. I reached out to the company, and they promptly sent me a new, fresh product. I own a business myself, and I know that things can happen like that. So, I appreciated the company's willingness to stand behind their product and send me a new one. That is why I updated this to five stars.
