Dietary supplements: what works, what’s safe, and where to read more

Most people take at least one dietary supplement, but many buy the wrong product or a useless dose. This page cuts through the noise so you know how to choose supplements that actually help and how to avoid risks.

How to pick safe supplements

Start with why you’re taking a supplement. Is it for nutrient gaps, immune support, hair growth, or to ease digestion? Match the product to that goal—don’t buy vague “wellness” blends that promise everything.

Check the label. Look for the active ingredient, exact dose, and form (for example, magnesium citrate vs. oxide). If a product hides doses behind proprietary blends, skip it.

Certifications matter. Third-party testing by organizations like USP, NSF, or ConsumerLab can’t guarantee results, but they reduce the chance of contamination or wrong dosage. No badge at all? Be cautious.

Watch for interactions. Supplements can change how prescription meds work. For example, some herbs affect blood thinners or blood sugar. If you take medication, ask your clinician before starting anything new.

Be realistic about claims. Supplements won’t replace medicine for chronic disease. Look for studies or meta-analyses that back a claim—single small trials aren’t enough to base long-term use on.
