I have read about the amazing properties of vitamin D (in particular D3) for heart protection and against such ailments as winter depression, etc. I understand that for people living in cold winter areas or for people who never spend time outdoors these supplements are very valuable. On the other hand I remember to have read that if you spend as little as an average 15 minutes per day outdoors you are going to produce enough vitamin D for your daily requirements. My question is: is vitamin D supplementation needed for everybody, or just for the people who lives in areas such as New York or Boston (cold winters) as opposed to Los Angeles or Florida? Also is it right that you will have enough exposure with just 15 minutes walks outdoors or do you rather need much longer exposure to cover your needs of vitamin D?

Dr Tourgeman Nephrologist..kidney Doc...practices in Fort Lauderdale. He has stated that almost all his patients are deficient in Vit D3 even though they all live in Florida. Most people everywhere coverup and use sunblock due to skin cancer scare. Just imagine how deficient people that live in the cold north are. And I do remember seeing a map of the US that plotted colon cancer The Northeast section of the US has a much higher incidence. http://nephropal.blogspot.com/ http://nephropal.blogspot.com/search/label/vitamin%20d A search for Vit d Dr T has 32 posts on Vit D. Just keep going and look at older posts to see them all Vitamin D is not something that is routinely tested for by the mainstream medical practitioners. Unless you are a lifeguard year round or are congnizant that 20 min a day in full sun in shorts and sports bra or no shirt then supplementation is necessary. |

The duration and exposure amount necessary is up for debate (we've heard 25% body exposure for at least 25 minutes), but the principal idea is sound. In general, if you're not getting natural sunlight for a reasonable amount of time on a good chunk of your body, then you should probably supplement with vitamin D. |

I recommend getting bloodwork to test your Vitamin D levels. I started taking 10k IU per day about 6 months ago, but didn't get it tested until a couple of weeks ago. It was 120 ng/ml, which is pretty high. I live in central California and am able to walk in the sun for 30 minutes at least a few times most weeks even in the middle of winter. |

Yes low levels of vitamin D are associated with many health problems. The important thing is to have your own actual vit D levels tested, then you will know exactly where you stand on supplementation needs & dosages. https://www.directlabs.com/Resources/Vitamins/VitaminD/tabid/273/language/en-US/Default.aspx |

I work all day long, no sun exposure. Here's my experience Started taking D3 back in Feb'11 with 2000UI/day, mid-May'11 upped to 4000UI/day, started to walk outside 1-2 hours a week in shorts and short sleeve t-shirt, mid-Aug'11 upped to 5000UI/day. Last week run a 25OH-D test and it came back as 57.7ng/dL. Pretty nice, in my opinion. |
