For veterinary professionals, the ability to evaluate these claims against the evidence hierarchy is not optional — it is…
The question “probiotic or postbiotic?” is increasingly common in veterinary practice. Owners arrive with products purchased online, asking whether the live-culture powder is superior to the heat-killed alternative, or whether they should be using both. The honest answer is nuanced: these are mechanistically distinct interventions with different evidence profiles, different strengths, and different limitations. This…
