Organic Roasted Seaweed With Sea Salt

Goes beyond a total-arsenic measurement to separate arsenic into its distinct chemical forms ("species"). This matters because toxicity depends on which form is present: inorganic arsenic (arsenite and arsenate) is a known human carcinogen, while arsenobetaine — the "fish arsenic" common in seafood — is largely harmless and passes through the body. A standard heavy-metals panel reports only total arsenic, which can overstate risk; speciation reveals how much of the arsenic present is actually the inorganic kind. This test can be performed as a follow-up to the total-arsenic measurement in the Heavy Metals Panel.
