Sean,

Hoppy is spot on.  Starting the anti-inflammatory regimen with 10,000 IU/day vitamin D3... not D2... is the fastest way to get your CH under control.

According to the experts in vitamin D therapy, vitamin D3 is three to four times more effective than vitamin D2...  Some physicians like to use vitamin D2 because it's a prescription item...  Vitamin D3 is an over the counter USP available almost everywhere.

It's not that your physician is giving you a bum medical advice...  He's just using a dated standard of care treatment guideline for a vitamin D3 deficiency...    See the following link why you should be taking vitamin D3 and not vitamin D2:

I take it from one of your first posts that you live in Virginia...  If you can get to Costco, they've got the best price on Nature's Bounty 5,000 IU vitamin D3.  Giant Food Markets also carry the complete list of supplements used in the anti-inflammatory regimen.  The other brand of vitamin D3 I suggest is Nature Made... 

The main reason I suggest these two brands is because the ingredients are prepared here in the US and carry a U.S. Pharmacopeia (USP) label...  The USP label indicates the USP has conducted an independent laboratory analysis on the supplement to ensure purity and strength...

You won't find a USP label on Nature's Bounty supplements.  However, their facilities have been successfully audited by the United States Pharmacopeia and STR (Specialized Technology Resources), a leading independent dietary supplement quality evaluation firm.

Unfortunately, there are some brands that are produced in China where USP type organizations do not exist...  Some of these supplements are tainted with possible toxins and few provide the strength listed on the label...  This is one case where made in the US is a must...

Back to treating your vitamin D3 deficiency...  CH'ers with low 25(OH)D lab results, i.e., < 20 ng/mL have successfully used an accelerated vitamin D3 dosing schedule consisting of 25,000 IU/day plus a 50,000 IU loading dose of vitamin D3 once a week on top of the daily dose. 

They also take the rest of the anti-inflammatory regimen including 1000 to 2000 mg/day Omega-3 Fish Oil and the vitamin D3 cofactors: 500 mg/day calcium (calcium citrate preferred), 400 mg/day magnesium, 10 mg/day zinc, boron, vitamin A (retinol) and vitamin K2 (MK-4 & MK-7) at RDA.

the simple way to get most of the cofactors is to buy the Kirkland brand of calcium citrate or Citracal Plus... They both have similar formulations.  You'll also need to add a tablet of Centrum Silver or the Safeway brand Century Senior 50+ Formula to get the vitamin K2 and vitamin A.  Hope this helps.

Take care and please feel free to ask questions...
