Some various products on iherb to compare
[Digestion, Stomach
Gas, bloating, belching, loss of appetite, nausea and discomfort may indicate a more serious condition, or dyspepsia, which is a generalized term for poor digestion. Chronic dyspepsia should be investigated for the root cause, which could be esophageal reflux, gallstones, an ulcer or another condition. Enzymes, probiotics, as well as artichoke leaf and turmeric may support digestive health. ]
