Review your supplements periodically

Periodically review why you take each supplement, its ingredients, quality information and possible interactions.

At a glance

  • What we know: A periodic review helps document ingredients, reasons for use and possible overlaps.
  • What’s uncertain: No clinical outcome is graded for this review routine.
  • First step: Make one list of all supplements and medicines with their ingredient amounts.
  • Before you try it: Discuss clinically indicated products before changing or stopping them. All precautions

Takeaway

NIH guidance recommends keeping a supplement and medicine record and discussing it with a health professional. Independent quality testing can help check contents and contamination but does not establish effectiveness or guarantee safety. Emergency-department surveillance documents adverse events from supplements; it does not prove that a periodic review prevents them. This Basic entry provides a practical review routine without a graded clinical-effect claim.

Practical steps and precautions

How to try it

  1. List every supplement and medicine, including the ingredient amounts, frequency and reason for taking each.
  2. Check for repeated nutrients across tablets, powders, drinks and fortified foods rather than looking at each label alone.
  3. For each product, distinguish a diagnosed need from a desired performance or wellness outcome, and separate evidence for that outcome from quality testing, testimonials and brand marketing. Independent purity testing does not prove clinical effectiveness; avoid copying a speaker’s complete stack.
  4. Review the list with a pharmacist or clinician when starting a medicine, before surgery or when your health circumstances change.

Precautions

  • Keep clinically indicated or prescribed products in the review; do not stop them solely because an influencer criticizes supplements.
  • Pregnancy, childhood and regular medicines require particular attention to suitability and interactions.

Sources: nih-2023-supplement-label-review, geller-2015-supplement-adverse-events. October 3 training follow-up: Clarified indication, quality and effectiveness as separate questions; video notes disclose Hyman’s commercial context. Independent editorial approval remains pending. Publication release 2026-10-04: site owner authorized a bounded AI audit and release of this exact revision. See docs/release-audit-2026-10-04.md for source-check findings and limits. No independent health-professional or peer review is claimed. Category migration 2026-10-04: removed the separate goals field; categories: Long-term health → Long-term health. Research assessments, sources, guidance, precautions, and evidence review dates are unchanged. This revision awaits publication approval; no new evidence review is claimed. Publication approval 2026-10-04: site owner explicitly accepted all current category-migration revisions for deployment and requested that remaining limitations be retained in docs/content-review-backlog.md.
