A high-dose, soy and gluten free iodine and potassium iodide tablet aimed squarely at thyroid support rather than general nutrition.
A basic, regulation-capped potassium caplet for general dietary supplementation, not a treatment for diagnosed low potassium.
A basic, low-dose potassium gluconate caplet meant for everyday mineral support, not a substitute for a doctor-prescribed, higher-dose potassium product.
