Prep Tip
Soak dried varieties like wakame briefly before use; toasted nori can be eaten straight from the package.
Absorption Boost
Healthy fats — helps absorb seaweed's fat-soluble vitamin K
Citrus or vinegar — a traditional pairing that also adds vitamin C
Use Caution If
You have a thyroid condition — iodine content varies widely by type and can be very high in kelp specifically; check with a doctor before regular use
You're on a low-sodium diet — many seaweed products are salted or naturally sodium-rich
Storage
Store dried seaweed in an airtight container away from moisture; it keeps for months.
