Supplement FAQ
How do I compare supplement labels?
Quick answer
Supplement labels can look similar while hiding important differences. First compare the active ingredient amount per serving, the form, serving size, other active ingredients, allergens, testing signals, and warning text. Price is useful only after you know what each serving actually provides.
Label check
- Active amount per serving
- Ingredient form and serving size
- Testing, allergens, and warning text
Safety and when to get advice
- Front-label claims can be less useful than the Supplement Facts panel.
- Avoid stacking products with overlapping ingredients unless the total intake is clear.
What the evidence can tell you
Research findings depend on the preparation, dose, population, and outcome studied. Ingredient evidence does not establish that every product works, and an absence of reported side effects cannot rule out uncommon reactions.
