Can kelp help with hyperthyroidism?
Because of its very high iodine concentrations, there is no “probably” about it: Kelp should profoundly NOT be taken in case of hyperthyroidism (overactive thyroid). Taking it would more than likely induce acute psychosis in addition to several other highly negative symptoms in keeping with acute hyperthyroidosis. To be avoided at all costs. Excellent for low or hypothyroidism. NOT for use in high or excessive thyroid symptoms.
