Probiotic and Zinc Supplement
Probiotics can also serve as remedies for the stomach flu. In the case of viral gastroenteritis, Lactobacillus casei GG and boulardii may be helpful; they could also help in water diarrhea. The best probiotic supplement is yogurt; however, make sure the fat is low or completely free from it. Some zinc supplements would also help to relieve the pain and duration of the stomach flu.
