Vitamin D is THAT Important...Start Now

I posted about a week ago about the importance of Vitamin D (in fact its not even considered a vitamin anymore but a hormone, that's how important it is) and how most, if not everyone, are deficient in vitamin D.

I just read a recent blog post from a colleague of mine in the fitness industry, Tony Gentilcore, and he talks about a recent study done on vitamin D and how we need more of it than we think.

Vitamin D=The He-Man of Supplementation
by Tony Gentilcore

I know, I know, I must sound like a broken record with the vitamin D talk yet again. But I thought I would pass this along to all of you because I thought it was interesting.

From Reuters Health:

Giving school children very high doses of vitamin D is safe, and may be necessary to bring their blood levels of the nutrient up to the amount necessary for optimum bone growth and health, a new study shows.

It’s been fairly well established in the literature (especially within the past 1-2 years) that vitamin D supplementation in adults is perfectly safe, and to a degree, almost mandatory. With a plethora of health benefits such as improved bone strength/bone mass, increases in lean muscle gain, improved cardiovascular health, improved blood pressure, improved sense of well-being (it’s no coincidence that we tend to feel down in the dumps during the winter months), and improved immune function.

In a previous study, Fuleihan and colleagues found that giving 10- to 17-year-olds relatively high doses of vitamin D3 increased their bone mass and bone area, as well as lean mass. In the current study, they report on both the short- and long-term safety of high-dose supplementation.

You can read the article (link above), but I’ll summarize the results of the new study:

***Currently, the Institute of Medicine recommends 200 IU of D3 daily for children. In the current study, the high dose was 2,000 IU daily. Or what I like to call, “lets see what happens.”

Short-term study: 25 school children took either a placebo or 14,000 international units (IU) of vitamin D3 per week for eight weeks. Levels of the vitamin in children treated short-term rose from 44 to 54 nanograms per milliliter (ng/mL).

Long-term study: 340 participants took either a placebo, 1,400 IU weekly, or 14,000 IU weekly of vitamin D3, and were followed up at six and twelve months. In the long-term study, levels rose from 15 to 19 ng/mL in children given 1,400 IU weekly and from 15 to 36 ng/mL in the higher-dose group. And no one grew a third head or developed some crazy mutant power.

Of course one could argue (ie: me) that vitamin D supplementation wouldn’t even be an issue if kids would actually go outside for a change, rather than spend their free time on the internet or playing Rock Band.

So put down the remote, get off the couch and get outside in the sun and get your vitamin D!...or if you want to watch TV guilt-free, take a 2000 IU of vitamin D3 per day...this is what I'm going to do...hehe don't tell my trainer...oh wait, that's me...
