How Vitamin D3 with Sea-Iodine Works

Life Extension Vitamin D3 with Sea-Iodine is a vitamin D supplement with organic algae and potassium iodide supporting normal bone function.

Vitamin D3 can be synthesized by humans in the skin upon exposure to ultraviolet-B (UVB) from sunlight. But, due to the winter season, weather conditions, and sun block, the body’s capacity to produce normal vitamin D levels may be inhibited. These factors point to the value of taking a daily vitamin D supplement.

Vitamin D supports normal bone density, normal cell division and differentiation, and normal immune function.

Iodine is a trace element essential for life. Its primary biological role lies in the production of the thyroid hormones triiodothyronine (T3) and thyroxine (T4).16 T4 and T3 contain four and three atoms of iodine per molecule, respectively. The thyroid gland actively absorbs iodide from the blood to make and release these hormones into the blood.
