Conditions

Conditions covers the symptom you actually have, rather than the product aisle you happen to be standing in. There are four guides here: IBS, acid reflux and GERD, constipation, and bloating. Each one starts from the condition, walks through the treatments that have been trialled for it, and ranks them by how strong the evidence is — not by what is easiest to sell.

That produces some answers people do not expect. Nerva's gut-directed hypnotherapy edges out peppermint oil and probiotics in the IBS trial data. MiraLAX (PEG 3350) beats fiber and short-term stimulant laxatives for chronic constipation. For reflux, a fast H2 blocker like Pepcid and a daily PPI like Prilosec or Nexium solve different problems, and which one is right depends on how often your symptoms occur. For bloating, enteric-coated peppermint oil has the best condition-specific evidence, ahead of the gas-focused products most people reach for first.

Each guide opens with a short direct answer, then explains the reasoning and the limits behind it, including when a symptom warrants seeing a doctor instead of buying anything. Read the guide for your symptom first; it will point you to the product ranking in Reviews if a supplement is genuinely part of the answer. Nothing here is medical advice or a diagnosis.
