Porphyra Yezoensis Nori supplementation for targeted health support.
Controversial. Nori contains B12 analogues but their bioavailability for humans is debated. Some studies show benefits, others don't. Don't rely on it as sole B12 source.
30-50% of dry weight is protein, which is high for a plant. However, you'd need to eat a lot of nori to get significant protein. Better as mineral source.
Moderate. Lower than kelp but still provides iodine. Generally not a concern unless eating very large amounts.

Roasting changes flavor (more savory) and may reduce some nutrients. Both are nutritious. Roasted is the common form.
Sushi provides some nori. If you want more nori nutrition, eat the sheets directly or use more generously. Supplement form isn't necessary.
Most research uses 7.0g daily. Below 2.0g, you're probably wasting money. Above 15.0g, no extra benefit. The curve plateaus. Safe upper limit ~ 30.0g.
