I like these enzymes for every day use. But I also make sure I take them if I have an extra heavy meal. And they seem to help digest it better.
I would definitely buy them again.
So I guess there really is no way to tell if you are lacking in some of these enzymes unless you get come comprehensive blood work done??
I use these for my elderly dogs, it helps the one with pancreatitis from having painful flare-ups. The other one can have tastier meals with a bit of fats at times without worry. Now it works for my adopted pup, keeps his coprohagia at bay.
As for the humans at home, we are all above 50 yo, but still enjoys eating and this help with reducing flatulence by a lot!
This is the one digestive enzyme product that actually helps me.
