Product quality before purchase

How to judge supplement quality before you buy

Use this checklist after you have narrowed your goal, compared evidence, and checked safety. Product quality is where standardized extracts, transparent labels, heavy-metal testing, certificates of analysis, and dose clarity determine whether a supplement is worth considering.

1

Verify standardization

Prefer labels that name the extract form and marker compounds, not vague root, leaf, or proprietary blend language.

2

Look for third-party testing

Certificates of analysis and independent testing are strongest when they cover identity, heavy metals, microbes, and solvent residues.

3

Avoid hidden-dose blends

Proprietary blends can hide under-dosed or over-stacked formulas. Favor transparent products with clear ingredient amounts.
