Before spending money

  • Does the ingredient have direct human evidence for the outcome I care about?
  • Does the product match the form and dose studied?
  • Is the label transparent enough to compare with the research?
  • Is testing and formulation information verifiable?
  • What safety or medication-interaction questions still need review?
  • What evidence or quality failure would make me skip it?

Use the worksheet side by side

  • Compare form, active amount, standardization, testing, COA status, formulation verification, safety cautions, and evidence context.
  • Treat a blank field as a data gap, not a positive score.
  • Never let a retailer link or commission raise either an evidence grade or a product-quality score.
Use this as a research framework, not a treatment plan. The resource helps organize evidence, product-quality, and safety questions. It does not determine whether a supplement is appropriate for a specific person.
