Saffron

Choose saffron that lists grade (e.g., ISO 3632), shows deep red threads with minimal yellow styles, and provides origin and harvest information; look for third-party lab testing for purity and absence of additives when available

Saffron is sold as whole threads, powdered saffron, and extracts or capsules; whole threads preserve aroma and allow precise dosing for tea, while standardized extracts or capsules offer measured concentrations for supplement use

Culinary uses typically use a small pinch (a few threads) per serving; therapeutic supplement doses commonly range from 15–30 mg per day in studies, and consuming large amounts (several grams) can be unsafe, so follow product directions or consult a healthcare professional

Check for lab or certificate of analysis, examine threads for uniform deep red color and lack of dust, perform simple at-home checks (saffron threads release color slowly in water and retain red hue rather than dyeing water instantly), and buy from reputable sellers with transparent sourcing

Prices vary widely depending on grade and origin; budget saffron or blends may be under $50, while higher-grade or certified saffron typically averages in the tens to hundreds of dollars per small container; compare per-gram cost when evaluating value

Store saffron in an airtight, lightproof container in a cool, dry place away from heat and moisture; whole threads retain flavor and compounds longer than powder when properly stored

Saffron can affect mood and blood pressure, so people taking antidepressants, blood pressure medications, blood thinners, or pregnant individuals should consult a healthcare professional before use to assess potential interactions or contraindications
