Hi tpierpoint
Pancreatitis is more likely to develop deficiencies of the following nutrients:

Magnesium – particularly in the cases of chronic alcoholism

Methionine

Selenium

Vitamin A

Vitamin C

Vitamin E
Some studies do suggest that taking these nutrients mentioned, particularly the latter five each of which has antioxidant properties, can reduce the pain from which people with pancreatitis suffer and recover more readily from the condition. Other potentially valuable supplements to take include:

Vitamin B12; levels may be low with pancreatitis; works best in this case if given by injection.

Soybeans; extracts of soybeans known as polyunsaturated phosphatidylcholines (PCs) work as antioxidants and have demonstrated prevention of damage to the pancreas in animal studies.

Gynnema Sylvestra has been shown to REGENERATE pancreatic cells and even normalizes insulin and blood glucose levels.

In one recent study of only three patients with chronic pancreatitis (inflammation of the pancreas), a commercially available grape seed extract significantly reduced the frequency and intensity of abdominal pain after conventional medications failed to improve symptoms.

I would recommend using anti-inflammatory herbs, especially turmeric and ginger based products. Follow dosage recommendations on the labels or inserts.
I would also recommend grape juice to help the liver and bile ducts.
Especially a soothing tea made with ginger and slippery elm.

There are some good natural digestive enzyme supplements that will help also.
Aloe vera juice or gel and papaya are helpful too.

Avoid anything that is highly spiced and to avoid any food that triggers pain.
