Life Extension Vitamin D3 with Sea-Iodine, 5000 IU, 60 Vcaps

Vitamin D is synthesized in the body from sunlight. But, due to the winter season, weather conditions, and sunscreen blockers, the body’s ability to produce optimal vitamin D levels may be inhibited.

In fact, it has been proposed that annual fluctuations in vitamin D levels explain the seasonality of influenza. All of these factors point to the value of taking a daily vitamin D supplement to ensure optimal vitamin D intake.

Vitamin D has long provided significant support for healthy bone density. 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.

These findings link a deficiency of vitamin D to a host of common age-related problems.

The current RDA is only 400 IU. As a result of startling evidence of a widespread vitamin D deficiency, prominent nutritional scientists are calling on Americans to increase their vitamin D intake to 1000 IU per day and higher.

Currently, most experts in the field believe that intakes of between 1000 and 4000 IU for adults will lead to a more healthy level of serum 25 (OH)D, at approximately 75 nmol/L.

Life Extension recommends that healthy adults supplement each day with at least 1000 IU of vitamin D. Elderly adults may benefit from higher doses such as 2000 IU daily, and even up to 5000 IU daily.

Americans have rightly been told to avoid table salt for decades in order to reduce their risk of hypertension and related health conditions. When iodized table salt is reduced, people can unknowingly lower their iodine intake to suboptimal levels.

Analyses from the National Health and Nutrition Examination Survey (NHANES) show that urinary iodine levels have plummeted since the 1970s.

Iodine is a health-promoting trace element essential for life. Its primary biological role lies in the production of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). 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.

Iodine is found abundantly in sea vegetables and plants. In areas where no marine foods are eaten, people have lower iodine levels.

For this reason, US commercial salt manufacturers have added iodine to their product since the 1920s, in order to deliver this key ingredient to your diet.

However, we now know the dangers associated with eating too much table salt, resurrecting the dilemma of where to get healthy sources of iodine.

Ironically, health-conscious people are often most likely to develop low iodine levels. One reason is that athletes and people engaged in heavy physical effort deplete their natural stores of this trace mineral through perspiration, increasing their need for it.

Vegetarians also have substantially greater likelihood of low levels of iodine than carnivorous people, since foods of plant origin are less rich in iodine than animal-derived foods. One study demonstrated iodine deficiency in 25% of vegetarians and 80% of vegans.

The good news is that you can avoid iodized table salt without sacrificing the health benefits of iodine. For the first time, Life Extension introduces Sea-Iodine, a low-cost proprietary formula that health conscious individuals can take each day to support optimal iodine levels.

Using standardized extracts harvested from a blend of marine algae, Sea-Iodine brings you the health of the sea while avoiding the well known dangers of excessive salt intake.

The purified algae extracts found in Sea-Iodine come from the pristine waters of Iceland, Nova Scotia, Italy and Norway, providing over 667% of the Recommended Daily Value of natural iodine.
