Safety guide

Critical T safety: questions to answer before buying

A supplement being sold online does not make it appropriate for every person. Review the current label, serving size, warnings and ingredient amounts, and discuss supplement use with a qualified clinician if you take medicines or have health concerns.

Editorial note: This page is educational and is not medical advice. Product formulas, prices and seller terms can change; verify the current label and checkout page.

Safety checklist

Read the complete Supplement Facts panel and warnings. Consider total intake from other supplements. Ask a clinician or pharmacist about possible interactions if you use prescription or over-the-counter medicines. Seek medical evaluation for persistent symptoms rather than using a supplement as a substitute for diagnosis or treatment.

Why we avoid “safe for everyone” claims

FTC health-product guidance notes that advertising can be misleading when material safety limitations are omitted. Safety depends on the actual formula, dose and individual context.
