How To Take Vitamin D, How Much You Need, How To Measure Efficacy

From the Heartscan Blog (http://www.heartscanblog.blogspot.com/):
The three big takeaways are:
--"We use 60-70 ng/ml of 25-hydroxy vitamin D as our target. Most men and women require 6000 units per day to achieve this level."

--"I advise everyone that gelcap vitamin D is preferable. Some, though not all, liquid drop forms have also worked. Take a dose that yields desirable blood levels.

--"And blood levels of 25-hydroxy vitamin D are ideally checked every 6 months: in summer and in winter to provide feedback on how much sun activation of D you obtain. If your doctor is unwilling or unable to perform vitamin D testing, fingerstick vitamin D test kits can be obtained from Track Your Plaque."
