New Era Comb E contains calc phos, mag phos, nat phos and nat sulph. Nat phos is the tissue salt most often associated with acid balance, mag phos is commonly used for cramping and colicky discomfort, calc phos is often included when digestion is weak after eating, and nat sulph is traditionally linked with sluggish digestion and biliousness.
That makes New Era Comb E a useful option when indigestion comes with trapped wind, griping pain or heaviness after food. Instead of focusing on one symptom only, the blend covers acidity, spasms and digestive sluggishness together. Biotin is also included as an added nutrient for general metabolic support.
Mag phos and nat phos are the key pairing here if you are buying for colic or flatulence. Nat sulph broadens the formula when food seems to sit badly, especially after rich meals, and calc phos helps round out the digestive support side.
