Andreas - I have candida so I started taking digestive enzymes to help digest my meals. I have muscle soreness after a couple of days taking a particular brand. It's an vegetable based enzyme with enzymes for sugars, protein and dairy. Could my body be reacting to the enzymes? Thanks.
The best way to find out is to stop taking them, and perhaps starting again. Yes, digestive enzymes can be very irritating, except when they body makes them.
