Biocore makes one of the best digestive enzyme formulas. Swanson Carries it solo, but it is the same blend in PES' Symbiont-GI.
I've experienced better success with digestive enzymes than natural digestive aids such as ginger, gentian, artichoke a d other bitters.
I do take a curcumin/berberine product as I find GDA's seem to help with my digestion. Other more comprehensive profiles have helped as well.
Probiotics: I've been experimenting with them over the years. The jury is still out on wether they are actually beneficial, necessary or even harmful, and I would avoid taking any probiotic that has a kitchen sink profile. Find out what strains help specifically with food digestion and work from there. My experience is even though I've used the strains best for my IBS-C and extremely high quity products, I'm not sure I've seen much difference in their use. I will probably continue on and off until I come to my final conclusion, or science makes a better determination on their use.
Now I could go on about the other supplements I take for my digestive disorders, but they mostly pertain to my IBS-C. Just ask of you're curious though.
And as far as doctors go; it's important to get checked out, almost a must but I'm not sure much more needs to be taken unless you have some serious issues and concerns. I have some of the best insurance you can get(not to brag) and I've exhausted my options with most specialist in Philadelphia. I've done just about every test: endoscopy, colonoscopy, anorectal-manometry, allergy testing. None have been conclusive and I've found most doctors try to treat each patient with a same blanket treatment. And/or don't have a great understanding past what is offered in modern medicine. It's as if they treat every digestive disorder the same.
