Low effectiveness due to negligible trace minerals (e.g., Mg 210mg/100g in Kona sea salt provides ~10mg/tsp, far below effective 300-400mg/day; Ca/K similar) despite animal hints of benefits from whole matrix (rat BP reduction SBP +40 vs +73mmHg refined salt, PMC5328355). Human evidence absent; consensus (Mayo, Healthline) deems no superiority. Safety deducted for heavy metals (Pb avg 7mg/kg in gourmet salts, PMC10459412) and sodium equivalence (~2000-2300mg/tsp). Quality low sans certifications
Mineral sea salt offers no proven health advantages over iodized table salt due to insignificant mineral contributions and equivalent sodium load. Potential heavy metal risks further diminish appeal. Opt for iodized table salt for thyroid support at lower cost.
