Surprising as it may be, vitamin D is not really a vitamin at all. It's actually a pro-hormone that's been produced by life forms for over 750 million years. Most animals that are exposed to sunlight have the capacity to make their own vitamin D.
In people, vitamin D3 is synthesized in the skin through exposure to ultraviolet B radiation from sunlight. Optimal Vitamin D levels are critically important for the development, growth, and maintenance of the human body ... from gestation on.
In fact, every cell in your body has a vitamin D receptor and uses it to function properly. Vitamin D also acts directly on your genes, where there are 2,700 binding sites for this critically important hormone.
The current official daily adult requirement for vitamin D is 600 IU ... the amount you'll find in commercial multivitamins . But it's hardly enough. What with sunscreen and seasonal changes, the amount of vitamin D your body can make will vary widely. And a 600 IU supplement won't begin to stave off deficiency ... as many nutritional scientists have found.
To determine exactly how much vitamin D you actually need to take, you need to know your vitamin D blood level. So make a simple vitamin D blood test part of your annual physical to enable your doctor to suggest an appropriate dose.
Life Extension® recommends that healthy adults supplement with at least 2,000 IU each day. Elderly adults may benefit from 5,000 IU to 10,000 IU daily, based on their individual test results. The goal is to achieve an optimal vitamin D blood level between 50 and 80 ng/ml.
Another thing to consider adding to your supplement regimen is iodine.
Americans tend to avoid table salt to reduce their risk of hypertension and related health problems. But when iodized table salt is reduced, people can unwittingly lower their iodine intake to suboptimal levels. In fact, analyses from the National Health and Nutrition Examination Survey (NHANES) show that iodine levels have plummeted. And that's serious. Iodine is a health-promoting trace element that's essential for life. Its primary biological role lies in the production of thyroid hormone.
Iodine is abundant in sea vegetables and plants. In those geographic areas where no marine foods are eaten, people typically have lower iodine levels. For that reason, US commercial salt manufacturers have added iodine to table salt since the 1920s. But now that we're more aware of the dangers associated with too much salt, it's important to find another way to safely supplement our iodine intake.
So Life Extension has combined Vitamin D3 with Sea-Iodine™ ... derived from purified, standardized extracts of marine algae, harvested in the pristine waters around Iceland, Nova Scotia, and Norway.
Now you can avoid two deficiencies with one convenient, cost-effective formulation ... Life Extension's Vitamin D3 with Sea-Iodine™. It's simple, smart, safe ... and essential!
