Supplement Facts: Read Labels and Choose Safe Supplements

Want to know what’s really inside that supplement bottle? A label can hide pricey fillers, weak doses, or ingredients that clash with your meds. Use simple checks to tell good products from marketing noise and keep your health on track.

Start with the basics on the Supplement Facts panel. First look at the serving size — if the dose you need is three capsules but the serving is one, you’ll be taking more pills than you expect. Check the active amounts (mg or IU) and the % Daily Value when available. Watch for "proprietary blends" — that means the maker lists a total weight without showing how much of each ingredient you get. If an ingredient matters to you, proprietary blends are a red flag.

What to check on every label

Focus on four things: dose, purity, form, and warnings. Dose tells you whether the product can help (for example, look for clear leucine, isoleucine, valine amounts on BCAA formulas). Purity means few fillers and no hidden sugars or allergens. Form matters: some herbs work better as extracts than powders. Warnings and usage directions tell you when to avoid the product — and whether you should talk to a doctor first.

Safety tips that actually help

Buy supplements with third-party testing (USP, NSF, or ConsumerLab). These seals don’t guarantee results, but they do confirm the bottle contains what it says. Avoid miracle claims like "cures" or "detoxifies" — those are marketing flags. If you take prescription meds — especially blood thinners like warfarin or antidepressants like venlafaxine (Effexor) — double-check interactions.

Quick checklist before you buy:

• Read serving size and active amounts — not just ingredient names.
• Avoid proprietary blends for key nutrients.
• Look for third-party testing seals.
• Check for allergens, fillers, and expiration date.
• Search for interactions with your prescriptions.
• Buy from reputable sellers and check reviews and policies.
