KenDBerryMD talks about vitamin D deficiency and dosing!

This was a great talk I came across from medical doctor Ken D Berry.  
The highlights include:
-Vitamin D is one of the most highly overlooked deficiencies in the northern hemisphere.
-D3 is ore absorbable than D2 (both are fat soluble and should be taken with healthy fats / oils).  
-Doses range from 2000-10,000IU / day.
-No one has ever overdosed from vitamin D.
-Testing should be done 2-3x /year.
-Optimal levels need to be > 50nmol/L to notice achieve benefits.    

Thanks Dr Berry for the lecture - I completely agree with everything you say.  Vitamin D / magnesium deficiencies are one of the biggest issues affecting our populations health and wellness today!
