The number one question I receive continues to be, “How much should I take?” The answer to that question also continues to be, “There is no magic amount. You have to find what works for you – what gets you up to 40 – 60 ng/ml.” For the vast majority of people, it will be closer to 5000 IU/day, much more than the 400 or 600 IU found in most multi-vitamins. We’ve used your D*action data to create charts and calculators; tools to help provide a starting point or feedback for how your intake and serum level compare to others. But you still have to test, and it may take some trial and error to figure out what amount of sun, supplement and/or foods get your level in the 40-60 ng/ml range.

This is a process, like all health matters. It can’t be determined overnight. You need to test, change habits, test again.

D*action was created in 2009 as both a study platform and a way to provide inexpensive, at-home vitamin D tests. Some of our participants reported that in 2009 if they wanted to test their vitamin D through their doctors, it was not covered by insurance and cost hundreds of dollars ($500 for one test!). Thankfully, this is no longer the case.

While you may be tested through your primary care doctor, it is now more important than ever to continue with D*action. The more participants we have who regularly test and report health outcomes (every 6 months is ideal) – the more powerful our data, our research, and our ability to reach out and spread the word.

Read on to learn more about how to determine the best supplement amount for you, and, a great testimonial too!
