Double dose is a starting dose. Otherwise, there will be no change in the serum level.
The Sunshine Vitamin

I appreciate that these little softgels are 2,000 IU - means I take 1/2 as many as my former 1,000. We all need more Vit D3, recent studies show. My naturopath suggests 5-6,000 a day and that 10-15,000 units (and more) are used in studies, but it's not a bad idea to obtain your current levels, via blood test.
Source Naturals Vitamin D-3 2,000 IU, 200 soft gels

The Holistic Industry is looking into the effects of Inflammation and Cardio issues with this at comparable doses of 5-10,000, I like moderation and tell clients to consider 2,000 IU's AM and PM I myself take that amount!
Best value D3 on the market!

My Vitamin D levels stay low from my MS and therefore my doctor highly recommended the Source naturals D3 I have been using it for a long time and it has brought my D levels up to 33mmol from 17.5mmol Not too strong, just right. I prefer this to the Drisdol RX because it is not synthetic, and I feel better with the natural D3 Try it, you will no doubt LOVE IT TOO!!
