The Miracle of Vitamin D: Sound Science, or Hype?
The title is overly provocative, but it looks like there is a good study on its way.

Thanks for posting the link.

It's unbelievable to me that the folks quoted in the article are trying to say there is a shortage of research on fish oil and vitamin D.

Effects of Vitamin D deficiency are well-established. Correcting that leads to better health. Quite simple.

The pharmaceutical industry must be losing $$ and sleep over so many people getting more vitamin D and correcting their deficiency diseases...

EDIT: Also, the witch-hunt for vitamin D toxicity will likely bear no fruit for the naysayers...
Risk assessment for vitamin D

We present a risk assessment based on relevant, well-designed human clinical trials of vitamin D. Collectively, the absence of toxicity in trials conducted in healthy adults that used vitamin D dose ≥250 g/d (10 000 IU vitamin D3) supports the confident selection of this value as the UL.
The lack of vitamin D toxicity with megadose of daily ergocalciferol (D2) therapy: a case report and literature review.

The maximum daily dose of vitamin D currently recommended is 2000 IU. Ergocalciferol (D2) 50,000 IU orally weekly for 8-12 weeks is often used to treat vitamin D deficient patients (25(OH) vitamin D <20 ng/mL). The lack of vitamin D toxicity after massive doses of ergocalciferol has yet to be reported in the literature. We report a case of a 56-year-old woman who received supratherapeutic doses of ergocalciferol (150,000 IU orally daily) for 28 years without toxicity.
Be afraid of vitamin D, we don't know if it helps yet, and it could be super-dangerous!!![/sarcasm]

What a crock.

Garrett, I have upped my Vit D intake to over 5000iu a day several months ago... my blood work comes back stellar.

My doc is considering taking me off my Diovan (genetic hypertension, I am pretty fit and eat well) and my cholesterol is always below 170.

Of course I take a ton of fishoil as well... but the both together seem to work wonders for my blood profile.

Garrett Smith 02-02-2010 11:58 AM

That's great Jay.

I'm up to around 7k iu per day, just because I'm taking 25k twice a week now.

I'll soon be testing out the algae DHA-only on myself, before potentially switching to it.

Garrett Smith 02-02-2010 01:21 PM

Research on DHA, EPA, O-3s, and PUFAs from 2001-2008 here:

Just to really demonstrate the supposed LACK of research on the topic of fish oil...

Steven Low 02-02-2010 05:00 PM

I've been on 10k IU vitamin D per month for about 4 months now or so.

Yep... pretty much.

Wayne Riddle 02-03-2010 03:53 PM

Been on 10,000 I.U's of Vitamin a couple of months now, along with a little over 5 grams of combined EPA/DHA a day. Didn't miss a day of work while others around me had colds and the flu.

Any thoughts on Poliquin's approach of doing 30,000 to 100,000 IU 2x a week?


Another approach, which I prefer, is to supplement twice per week with about 30,000 to 100,000 IU of D3. Based on the research and clinical evidence, this method seems to accelerate the increase in blood levels of 25(OH) D3 (the marker that should be tested for).

Steve Shafley 02-06-2010 08:37 PM

I have jumped on the bandwagon this winter with the vitamin d. between 8-10K a day.

coupled with nasal irrigation, this has really impacted how often I've gotten hit with colds this season.

With vitamin D being fat soluble I'm not sure how taking 30,000 I.U's twice a week is much different then taking 10,000 I.U.'s a day. I'll have to let someone that has done more research then myself answer that one.
