Add high quality fish oil, a good price/quality LIQUID fish oil is from alimentnutrition or maybe
caps from trueprotein.com . Or you can get any other, but take a look at fish source...sardines are the best ones. so about 10-15g a day with meals.
Probiotics can help too together with digestive enzymes and HCL
Try a low carb diet, 100-150g protein, healthy fats (like fish oil, almonds, coconut oil...) and a lot green vegetables (no other carbs then from green vegetables).
