they are extremely useful.
i once could no longer eat whatever without being hampered by heartburn.
No medicines & no doctors were of big help.
Then i started taking enzymes & now i can eat all i want.
I use DIGESTABS by puritan.com
They just supply your body with the catalyst needed to digest & absorb food properly.
In Germany enzyme depletion is considered a national epidemics.
Stress, refined foods, chemicals etc tend to decrease one's ability to produce enough enzymes.
I prefer the animal origin ones with ox bile: the "all vegetable" ones weren't much of a help in my case.
