In this case I did not read it because, to me, the study validates what we've theoretically known (and too often ignored in my opinion) all along, that care should be used when taking fat soluble vitamins. Not care, actually, as that's too strong. I mean not blantantly ignoring all warnings and living on the "if some is good an absurd amount must be great" ideal.Steve Edwardshttps://www.blogger.com/profile/17639176315514772554noreply@blogger.comtag:blogger.com,1999:blog-21280038.post-28358267974063154022012-03-06T18:01:05.426-07:002012-03-06T18:01:05.426-07:00I hesitate to make decisions based on one study.

Although the large number of participants theoretically makes this a really impressive sample size, it can also artificially amplify positive results. I would need to read the study myself, because there was no mention of controlling for age, nor I believe ethnicity. And there could be some statistical issues that account for the results rather than a true effect. There is a difference between something being statistically significant in a study this huge, versus realistically relevant. I'll look forward to future research, especially data that replicates this finding.Anita Marchesani, Ph.D.https://www.blogger.com/profile/17451706337499825157noreply@blogger.comtag:blogger.com,1999:blog-21280038.post-63891031017912491452012-03-06T17:41:38.525-07:002012-03-06T17:41:38.525-07:00I was deficient on my labs (25), so my doc put me ...I was deficient on my labs (25), so my doc put me on 20,000 IU per day. Did the trick. I'm now at 86, so we're dialing down to half the dose and will check again.

He said A,D,E and K are NOT water soluble so therefore a person can take to much of them and cause secondary consequences. The rest of the core vitamin family such as B and C are water soluble and therefore your body absorbs what it needs and excretes the rest- meaning you can't overdose on it. I love this article! I have a good friend taking 5,000 iu a day of D bc her dr. Told her to do I'm always giving her articles with D side effects!Jennifer Davishttps://www.blogger.com/profile/17951123246326798032noreply@blogger.comtag:blogger.com,1999:blog-21280038.post-91590138534592748532012-03-06T14:41:11.091-07:002012-03-06T14:41:11.091-07:00I was pale before it was cool.I was pale before it was cool.Hipster Bragnoreply@blogger.comtag:blogger.com,1999:blog-21280038.post-29223523499955123662012-03-06T12:26:25.016-07:002012-03-06T12:26:25.016-07:00alright Thanks Steve and yes lol i am that fit guy...alright Thanks Steve and yes lol i am that fit guy that did the 11/11/11 challenge with you back in November :) but i was just curious about if i was taking to much but i guess it's all good then since i'm active. being a graphic designer tho for my daily job i am inside most of the day tho so my sun exposer is actually pretty rare so it's probably a good idea that i take the extra anyway. thanks again!fausey14https://www.blogger.com/profile/05841694294706870841noreply@blogger.comtag:blogger.com,1999:blog-21280038.post-69595896182355217722012-03-06T12:24:46.480-07:002012-03-06T12:24:46.480-07:00if you click the links I covered that last time.if you click the links I covered that last time.Steve Edwardshttps://www.blogger.com/profile/17639176315514772554noreply@blogger.comtag:blogger.com,1999:blog-21280038.post-46042440090475163082012-03-06T12:18:30.093-07:002012-03-06T12:18:30.093-07:00The other part of this that hasn't been addres...The other part of this that hasn't been addressed is the fact that sunscreen significantly blocks vitamin d production. This means that while people may be spending a lot of time outside, they might still be deficient in vitamin d if they're using heavy amounts of sunscreen.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-21280038.post-75115975227290661882012-03-06T12:10:01.141-07:002012-03-06T12:10:01.141-07:00"This information is coming from Pharmaceutic..."This information is coming from Pharmaceutical journals and is passed down from my mother (the pharmacist) to me. Not only do I take a multi-vitamin with 400IU's of D3 in it, but I also take another 1000IU tablet as well. Anything over 2000IU's your body will just flush out of your system anyways, so if you are buying into the 2500IU or 4000IU tablets, it's a waste of money"<br /><br />This post was on one of my old blogs. If true then even the watchdog industries are spreading bad info. Hopefully with studies like this one it will start to change.Steve Edwardshttps://www.blogger.com/profile/17639176315514772554noreply@blogger.comtag:blogger.com,1999:blog-21280038.post-19674536101827092572012-03-06T12:08:42.782-07:002012-03-06T12:08:42.782-07:00I'd say it's high unless you never get out...I'd say it's high unless you never get outside. 400IU is the RDA, not that it means much, and I think from your name you're the super fit guy so you can likely use more. If it were me I'd dig into the study cited here and see what kind of levels were results in the reverse of inflammation. Keep in mind if you search the net there's a lot of bad info around. In fact, my wife's TWO docs both recommend her to take a vit D supplement and they have not offered to test her levels. And she's outside a lot. So there is definitely misinformation out there even amongst the informed.Steve Edwardshttps://www.blogger.com/profile/17639176315514772554noreply@blogger.comtag:blogger.com,1999:blog-21280038.post-71248464620233540832012-03-06T11:48:08.401-07:002012-03-06T11:48:08.401-07:00is 2000 IU to much of a daily dose?is 2000 IU to much of a daily dose?fausey14https://www.blogger.com/profile/05841694294706870841noreply@blogger.com
