Recognising and Reporting an Adverse Reaction

Attributing a symptom to a supplement is harder than it looks, and both over-attribution and under-attribution cause problems.

Distinguishing reaction from coincidence

Timing helps: symptoms starting within hours to days of beginning a product, and resolving after stopping, is a suggestive pattern. Recurrence on restarting is stronger evidence, though deliberately rechallenging is inadvisable for anything serious. Consider what else changed. If you started several products at once, attribution is impossible — which is the argument for introducing one at a time.

What to do

Stop the product. For anything suggesting allergic reaction, liver involvement, cardiac or neurological symptoms, seek medical attention rather than waiting. Keep the product, packaging and batch number — if analysis becomes relevant that information is essential and easily discarded. Photograph the label. Note the dates and symptom timeline while fresh.

Why reporting matters

Post-market surveillance is the main mechanism by which problems with specific products are identified, and it depends on reports. In the United States, adverse events can be reported to the FDA's MedWatch programme; comparable systems exist elsewhere. Reports from individuals are accepted and useful. Because supplements are not subject to pre-market safety review, this surveillance is doing more work in this sector than in pharmaceuticals, and it is chronically under-fed.

If you are considering Cognicept

Read the Cognicept ingredients page, which sets out both published ingredient lists side by side, and check the guarantee terms. If you take any prescription medication, obtain the supplement facts panel and show it to a pharmacist — the two candidate formulas carry quite different interaction profiles. Our buyer’s checklist sets out twelve checks.
