Hi everyone, computer problems (needed a new malware program) are fixed and I'm back up and running----still catching up a bit.
With the days getting shorter (boo, hiss)----I thought this article from News-Medical.net was timely. A study done in Great Britain with 1200 participants concluded that fair skinned people are more likely to be have deficient Vitamin D levels. Low levels of Vitamin D (and regular readers of this blog know that Vitamin D is a prohormone) are associated with increased risk for skin cancer, breast caner, osteopenia/osteoporosis, just to name a few. Fair skinned people tend to get less sun exposure, and use higher SPF sunscreens.
Depending on what lab/doctor you use, you will get a huge range of what is considered an optimal Vitamin D range--- my own physician uses 70-100 nmol/L. I struggle in the winter to maintain that level, even with 5000 IUs of Vitamin D daily (and we bump it to 10,000 IUs every other day and 5,000 on the alternate days from December to March). Summertime I'm usually fine with 5,000 IUs----I'm out doing water aerobics in our condo pool 4-5 days a week.
