Delores,
I think digestive enzymes are a good idea, as well as bile and liver support. For example, Designs for Health (D4H) has some good products that are certainly appropriate for an adult:
-Colon Rx – one to two capsules nightly before bed. This is magnesium hydroxide and triphala which helps with constipation and tone within the large intestine
-Phosphatidylcholine – one to two capsules nightly before bed to assist with bile production
-LV-GB Complex – this product is a combination nutrient to aide in liver function and bile release – two to four capsules daily.
In addition, some type of enzyme with HCL can be helpful. D4H has Digestzymes which is very good. One capsule with meals.
Many people like this are not getting enough fiber either and drinking enough fluids. A supplement called TruFiber is a soluble non-gritty fiber supplement that can be added to water or juice. I would suggest at least one tablespoon daily.
I hope this information is helpful.
