The human comparison measured serum concentrations
In the human part of the study, curcumin alone produced very low or undetectable serum concentrations. Adding piperine substantially increased measured concentrations during the early period after ingestion. [1]
The paper reported a 2,000% bioavailability increase. That percentage should remain attached to the tested amounts, comparator and measurement method; it does not mean twenty times more pain relief or disease protection. [1]
The study did not establish a daily treatment recipe
The experiment assessed pharmacokinetics rather than clinical symptom improvement. Its animal arm used different amounts and must not be substituted for the human comparison. [1]
The abstract did not fully establish human sample size, funding or conflicts. A brief report of no adverse effects cannot establish long-term safety or absence of medicine interactions. Adding an absorption enhancer should not be treated as automatically beneficial, particularly when a person takes prescribed medicines. [1]
Separate exposure from response
Imagine a blood concentration rises markedly while no symptom outcome is measured. The study has demonstrated altered exposure, not the size of a health benefit.
