For those of you in the Northern Hemisphere and northern US above Southern California, and Florida...it's time to start upping your vitamin D levels for the winter. We are not able to make it naturally in the skin anymore. Looking at 2,000 IU's a day from all supplements. It's best to have your vitamin D monitored by your physican/healthcare provider if you have any kind of autoimmune disease/condition.

Serum Vitamin D levels, What do they mean

Per Dr. Holick of Boston Medical Center and vitamin D researcher.

Normal or Suboptimal Levels of 25 hydroxy vitamin D
<10 ng/ml = severe deficiency
10-20 ng/ml = deficient
20-30 ng/ml =insufficiency
30-40 ng/ml = possibly insufficiency
>36 ng/ml = decreased incidence of heart disease
>40 ng/ml = decreased incidence of MS
40-50 ng/ml = probably sufficient levels
>50 ng/ml = sufficient or optimum levels
>50 ng/ml = decreased incidence of cancer
80-100 ng/ml = goal for most cancer patients
>125 ng/ml = potentially toxic


Be sure and find some time to get full spectrum light outside or from a full spectrum light to help with any seasonal affective symptoms too.
