Which two specific pre-existing organ diseases require individuals to seek medical clearance before using kelp supplements?
People diagnosed with kidney disease or liver disease should seek medical clearance before introducing kelp supplements.
Beyond thyroid sensitivity, the complex mineral load and potential for heavy metal absorption in kelp supplements necessitate caution for individuals with compromised primary excretory organs. Specifically, those diagnosed with pre-existing kidney disease or liver disease are advised to consult a healthcare professional before starting this supplement routine. The kidneys are responsible for excreting excess minerals and metabolic byproducts; therefore, pre-existing impairment in this system could increase the body's retention and risk associated with high intake. Although widespread evidence of liver injury from kelp is lacking, the concern stems from the sheer volume of substances absorbed from the sea potentially containing heavy metals.
