Kelp as natural thyroid support

As someone who prefers natural products, kelp helps me maintain thyroid health - specifically the production of the hormone T3 (triiodothyronine) as well as the T4 hormone (thyroxine). Kelp by Nature's Sunshine is one of the (natural) neutraceuticals that has kept me in good health. Nature's Sunshine is a brand that I trust and have used for many years. In these days of the pandemic it is imperative to maintain a robust immune system.
