How do I choose a supplement?

Start from your goal (e.g. sleep, energy, joint support), shortlist the options below, then favor brands with independent third-party testing — NSF, NSF Certified for Sport, USP Verified or Informed Sport. Always check with a healthcare professional, especially if you take medication.

Are supplements FDA-approved?

No. The FDA regulates supplements as food, not drugs — they are not approved for safety and effectiveness before sale and don't carry a recall-safety score the way prescription medicines do. That's why third-party testing and certification are the most useful quality signals.

What does 'third-party tested' mean?

An independent lab verifies that what's on the label is actually in the bottle — correct potency, and free of banned substances or contaminants. NSF, USP and Informed Sport are the most recognized programs.

Can supplements replace medication?

No. Supplements are not a substitute for prescribed treatment. The information here is general reference only and is not medical advice — consult a licensed professional before making changes.

How we cover supplements

The FDA does not approve or recall-rate supplements the way it does prescription drugs, so a recall-safety score doesn't apply. Instead we organize supplements by goal and type and steer you toward the real quality signal: independent third-party testing and certification (NSF, NSF Certified for Sport, USP Verified, Informed Sport, cGMP). Evidence for individual supplements varies and is often limited; this is general reference, not medical advice — always consult a professional.
