    Steve,
    Here's some info from Dr. Mercola. You might have to register on the site, not sure.
    Vitamin D Update – Carole Baggerly and Dr. Cannell

    He's pretty adamant about getting enough D and is also very upset, as are others who study the vitamin D issue, about the recent government recommendations for D.

    aa

    Edit: Just pointing out that he quotes quite a few credible sources and studies. The FDA is the last place you should be looking for reliable information.

    Wow thats loads more than me. My multi has 1600ui and my vit D tabs themselves are only 2000ui add on some sun and food and I usually sit right around the 5000ui per day mark. I assumed that was enough, but you guys seem to be doing a lot more... any noticable differences?

    My pharmacist and I were discussing this - he kept increasing his supplemental Vitamin D until his blood work was past 30, and he takes 5000 IU every day.

    I haven't had blood work yet, but got a nasty bout of acute bronchitis in August. After that, I started on 4,000 IUs of Vitamin D per day based on my reading at Dr John Birardi's Precision Nutrition site. Two interesting side effects:

    (1) I haven't been sick since even though my family keeps getting sick.

    (2) A nasty patch of eczema that has been on my left hand for well over a year and gets ugly in winter has completely disappeared. Coincidence? Maybe.

    Andy, interesting article, and I was able to read it without registering for anything (unless I'm already registered and I didn't know it.)

    Based on all this, I've increased my Vitamin D supplementation, up from essentially nothing (there was a little in my daily multi-vitamin) to a 2-3000 per day using the 1000 IU gel capsules I bought at Trader Joe's - one with my morning vitamins, another with dinner, and another before bed is the routine. We'll see how that goes and I may try more after that.

    You know, I am missing Comrade mc's input - mc, are you reading this one?

    Hi all:

    Really interesting discussion. Here is another useful piece to consider. It isn't a peer reviewed article but a decent newspaper story that summarizes the views and practices of a number specialists in the field:

    Scientists taking vitamin D in droves - The Globe and Mail

    I have been taking Vitamin D at about 1000 IU and have recently upped my intake to about 4000 IU. I am taking Vitamin D and fish oil and am eating a mostly paleo diet. I don't know which part of it is responsible (or whether there is synergy between all parts) but I haven't been sick at all this year and that is a huge change from years past. I am a university prof and generally at this time, as my students all get sick, I am wiped out, usually multiple times. This year, even though my students, colleagues, and family have gone down, I haven't even had the sniffles.

    Does a tanning bed provide any benefits? I live in Indiana and October to April I get no sunlight.

    Some notes on Vit D:

    It is not a Vitamin, it's a secosteroid, used by your body for a ton of metabolic functions; 25D being one of the main sources of fuel for your immune system.

    Those Wikipedia paragraphs you quoted are worthless. 25D stored in fat is inaccessible, only the blood level matters. Your kidneys use that to convert to 125D. A level of 30 is basically what anyone with a somewhat decent diet and not enough sun is going to have.

    50 ng/ml is where a healthy level starts. Individuals such as lifeguards who actually get some real sun during the day are going to be around 80-100 naturally.

    Ultraviolet-B exposure on bare skin is what makes D3 naturally. UVB is only available around the noon hour in North America. Anything north latitude of Memphis, TN does not even receive any UVB from late September to March. The body regulates production of D3 from the sun and you cannot overdose on it from exposure. Natural production will be somewhere around 30,000 - 50,000 IU on normal summer day with lengthy exposure. You cannot wash your skin immediately after exposure or it will ruin the D production, 24-48 hours for optimal absorption. Sweating like a hog while running or cycling is not an optimal way to naturallly produce D3. Stationary sunbathers have the edge here. Obviously, sunscreen is not a friend of D3 production.

    If you are receiving optimal sun exposure to produce your D3 naturally, make sure you are solid on your B vitamins, they are needed to resequence DNA constantly after forming pyrimidine dimers from UV exposure. Nucleotide excision uses nicotinamide adenine dinucleotide to facilitate this process and you need a healthy dose of B vitamins to keep this going.

    Supplementing D3 to raise your levels starts at around 4,000 iu to even move it. The fatter you are, the more you will need. 10,000 - 20,000 iu per day for the first month is a good start to really bump your level. Shoot for 50-80ng/ml.

    To anyone like the 2nd poster who has problems taking D3, you need to make sure you're also taking co-factors, especially magnesium. Magnesium glycinate is the best. Hypercalcemia is not what you are experiencing unless you are taking hundreds of thousands IU of D for months, massive amounts of calcium, or have kidney problems. Vitamin D Council | Understanding Vitamin D Cholecalciferol lists all the co-factors on the homepage.

    Start watching the youtube vitamin D videos by Holick, Heany, Cannell, Prendergast etc.

    I have recently gotten on this vit-d bandwagon. Doing about 4000iu daily now. But someone suggest that instead of this I go with one 50,000iu pill / week. This seems a cheaper alternative too. Is this a viable alternative?
