Take the Shaklee vitamin D quiz to determine if you are getting enough Vitamin D. Our dietary vitamin D requirements are influenced by a number of factors such as the time of year, our age, our skin color, our weight, our exposure to sunlight and where we live. So our vitamin D requirements are not all the same.

There is a lot of confusion today about how much vitamin D we should be getting in our diet. The official DRIs (the new term for RDAs) established by the Food & Nutrition Board of the National Academies of Science is around 400 IU for most adults. And the UL (upper limit for safe use) for almost everyone has been set at 2,000 IU for years.

Almost all experts agree that those levels are too low. Some doctors (including some that are popular on TV or the internet) have advised that everyone should be taking 5,000 to 10,000 IU of vitamin D/day. However, that's probably too much. Many experts warn that some people are likely to develop vitamin D toxicity at that level of intake. Yet, we are hearing that anywhere from 40% to 60% of Americans are deficient in vitamin D. No one wants to be deficient in vitamin D, but most people are confused. They just don't know how much vitamin D they should be getting in their diet.

This is where Shaklee research has really led the way. Shaklee has done three clinical studies to determine what vitamin D intake should be and how to get the vitamin D that you need. In the Landmark study (Nutrition Journal, 6:30, 2007) they demonstrated that people consuming a variety of Shaklee supplements for 20 years or more generally had optimal levels of vitamin D in their blood. They followed that with a study (submitted for publication) comparing Shaklee supplement users and non-Shaklee supplement users and showed that 1,000 IU of vitamin D from Shaklee supplements was associated with optimal blood levels of vitamin D for most people. And they have just completed a study with non-Shaklee users showing that supplementation with 1,000 IU of vitamin D from Shaklee supplements was sufficient to bring their blood levels of vitamin D from inadequate to adequate. So you might be tempted to think that all you need to do is get 1,000 IU of vitamin D from Shaklee supplements and you will be fine. It's not quite that simple.

You will notice I said that 1,000 IU of vitamin D from Shaklee supplements resulted in an optimal blood level of vitamin D for MOST people. But that doesn't mean that everyone in the study had optimal blood levels. There were some people who took 1,000 IU of vitamin D, but still had low blood levels. That's because there is tremendous individual variation in our need for vitamin D. Ou dietary vitamin D requirements are influenced by a number of factors such as the time of year, our age, our skin color, our weight, our exposure to sunlight and where we live.
Because of that Shaklee has lead the way again with a simple on-line quiz that anyone can take to determine their personal vitamin D requirements and a vitamin D3 supplement to help people customize their intake to match those requirements. Finally, someone has taken the confusion out of vitamin D supplementation!  However, I do have one final note of caution. There are some genetic differences that also influence vitamin D requirements, so I do recommend that you have your blood levels of vitamin D3 determined at your next doctor's visit.

To Your Health!
