Nutritional scientists are calling on Americans to increase their vitamin D and Iodine intake. Life Extension Vitamin D3 with Sea Iodine accomplishes this without the harmful effects of sodium by using blended extracts of marine algae.

Vitamin D

An avalanche of favorable studies has resulted in record numbers of Americans supplementing with vitamin D. Since it is virtually impossible to obtain adequate vitamin D from food sources, supplementation with 5,000-10,000 IU daily is required by many aging individuals.

Vitamin D has long provided significant support for healthy bone density.2-7 However, scientists have also validated the critical role that vitamin D plays in regulating healthy cell division and differentiation, and its profound effects on human immunity.8-15 These findings link a deficiency of vitamin D to a host of common age-related problems.


For many years, Americans have been warned to avoid table salt, and rightly so. Unfortunately, when we decrease our intake of iodized table salt, people can inadvertently reduce their iodine consumption to less than desirable levels. A series of studies conducted by the National Health and Nutrition Examination Survey (NHANES) demonstrate that urinary iodine levels have rapidly declined since the 1970s.

Iodine is one of life's essential elements, and works to promote health. Its fundamental purpose is found in the formulation of the thyroid hormones triiodothyronine (T3) and thyroxine (T4).16 These hormones possess three and four atoms of iodine per molecule, respectively. The thyroid gland vigorously takes in iodide from the blood to produce and discharge these hormones into the blood.

Satrirically, those who keep abreast of their own health are commonly at greater risk to develop low levels of iodine.17 A possible explanation for this is that athletes and those involved in heavy labor empty their natural reserves of iodine when they break a sweat, boosting their dependency on it. Vegetarians likewise have a much higher risk of having lower iodine levels than those who eat meat, because plant-based foods have less iodine than animal-derived foods. One analysis showed suboptimal iodine levels in 25% of vegetarians and 80% of vegans.18

On a  positive note, you can now eliminate iodized table salt without giving up the health benefits of iodine. Sea-Iodine is a cost-effective, exclusive concoction that health savvy people are able to take every day to promote ideal levels of iodine. The refined extracts in Sea-Iodine are obtained from the pure waters of Iceland and Nova Scotia, supplying more than 667% of the Recommended Daily Value of natural iodine.
