Vitamin D? How Much is Enough?

Vitamin D has really demonstrated itself to be beneficial in terms of the stimulation of immunity in a very general sense.

Hi again there folks, it’s Dr. Mike Breen here again from The Chiropractic Family Care Center, and The Healthy Transformations Program. Today, a little bit of information about vitamin D. Vitamin D is been on the radar for quite a while now, I’d say 15 to 20 years, in terms of a remarkable amount of science. Hundreds, if not thousands of peer reviewed studies in all of the major peer reviewed medical and health related journals have been formed on the benefits of vitamin D. And what’s really important is that vitamin D has really demonstrated itself to be beneficial in terms of the stimulation of immunity in a very general sense. And again, this relates to both innate immunity, adaptive immunity, autoimmunity, a whole number of things. And the studies that have been done have spanned all kinds of different health related issues. Whether it be heart or cardiac related research, cancer research, really, brain research. Everything really has been done in terms of the application of higher levels of vitamin D and E. Potential for it to improve health.

In 2015, the Dietary Guidelines Advisory Committee, which is a branch of the US Department of Agriculture. So government driven group of scientists, a very austere group of scientists identified that in the United States, vitamin D deficiency was so significant that the recommendations were that every American, and this includes people in Florida, Arizona and California, take between 5,000 and 10,000 international units of vitamin D per day. I live in Canada here and being this far north, it’s probably likely that the number would be slightly higher than that. But that’s what the Dietary Guidelines Advisory Committee found. You can look that up yourself if you’re interested. Point being is that there’s been a lot of data sent out about the values being still back in 1,000, or in some cases, even less than 1,000 international units per day. And it doesn’t look like that’s really enough to produce the benefits that are being driven by the research that’s being shown.

And what’s also interesting is the interpretation again, that we don’t need to take supplemental vitamin D, because we get enough from the sun. And yet the very best data suggesting that the amount of skin exposure that you need to get adequate amounts of vitamin D is really quite significant. Meaning, full body exposure. So playing golf, for example, with your arms exposed from the elbows down, and your legs from your knees down, wearing a golf shirt and shorts is not enough. But we’re wearing hats, and we cover our face is not enough skin exposure to actually get enough vitamin D. In fact, it’s now just a couple weeks ago, I read a study that said that 80% of the people in California are vitamin D deficient, as well as vitamin D deficiency is starting to show itself in Africa, of all places. And why is that? Well, it’s because of the urbanization of culture. So many more people are moving into cities. And what goes on in cities is urban-related behaviors, which is wearing clothes and working inside and all those other kinds of things. So, vitamin D supplementation is very, very important. I’d encourage all of you to do that and to follow the recommendations of a group of people as well versed in this as the Dietary Guidelines Advisory Committee. So, if you have questions about that, please don’t hesitate to reach out to me and I’d be happy to answer any more questions. Take care.
