How To Actually Read A Supplement Label

Watch for 'proprietary blends'

When a label lists a blend with a total weight but doesn't break down individual ingredient amounts, there's no way to know if you're getting an effective dose of anything specific — a red flag worth being cautious about.

Check for third-party testing certifications

Certifications like Informed Sport or NSF Certified for Sport indicate independent testing for banned substances and label accuracy — a meaningful quality signal, particularly important for athletes subject to drug testing.

Compare active ingredient doses to actual research

A quick search of the specific ingredient and dose against published research (rather than trusting marketing claims on the label) reveals whether a product actually contains a clinically relevant amount or just a token sprinkle.

Ignore the marketing buzzwords

Terms like 'clinically proven,' 'advanced formula,' or 'maximum strength' aren't regulated claims with specific meaning — they're marketing language that says little about actual efficacy or dosing.
