Nature's Way - Kelp 660 mg.

Kelp is collected from deep in the ocean because Kelp close to shore may absorb many heavy metals and toxins. Kelp has a long history of use as a food and as a source of assimilable iodine. It contains many nutrients absorbed from the sea.Nature's Way Kelp contains 400 micrograms of iodine which is 267% of your daily intake. Iodine is vital for good thyroid function, which in turn is essential for health. Iodine deficiency during pregnancy and early infancy can result in cretinism (irreversible mental retardation and severe motor impairments). In adults low iodine intake (or very high intakes) can cause hypothyroidism. Hypothyroidism can manifest as low energy levels, dry or scaly or yellowish skin, tingling and numbness in extremities, weight gain, forgetfulness, personality changes, depression, anaemia, and prolonged and heavy periods in women. Goiter, an enlarged thyroid gland visible between the Adam's apple and the collar bone, is often present. Hypothyroidism can also cause carpal tunnel syndrome and Raynaud's phenomenon. Hypothyroidism can lead to significant increases in cholesterol levels and homocysteine levels is implicated in about 10% of cases of high cholesterol levels. Correcting hypothyroidism can lead to a 30% drop in cholesterol and homocysteine levels.
