Researchers provide further evidence that vitamin D protects against cancer, after finding that people from Japan had a lower risk of the disease when they had higher levels of the "sunshine vitamin."

The 'normal' 25(OH)D range by my lab is 30-100 ng/ml. Cautiously optimal maybe would be anything between 50-80.

Here a graphic about the decreased incidence of various diseases with different serum levels from epidemiological studies in my dropbox:

Here an ng/ml to nmol/l online-converter:

ok that's what dr levy says
get into the 50 to 80 ng/ml range

While substantial variation in individual needs exist, most adults will not need to take more than 5,000 units of D3 daily to keep their blood level tests in the 50 to 80 ng/ml range – which is what I recommend.

5.000 IU (= 125 mcg) is a good starting dose. However, would always go sure by measuring a couple of months later and then at larger intervals for dose adjustments. Here my results averaged through the years:

Code: Select all

year: ng/ml - mcg

2009:       -   50
2010:   63  -  160
2011:   43  -  140
2012:   62  -  300
2013:   84  -  200
2014:   50  -  190
2015:   78  -  210
2016:   72  -  170
2017:  101  -  220
2018:   93  -  170


25(OH)D in serum 16 times tested. Lowest at 27 in 2011 and highest at 135 last year. Intake of D3 in average 193 mg/d (= 7720 IU/d) resulting in an average serum level of 70 ng/ml.

While substantial variation in individual needs exist,


Not only substantial between individuals, but even between different points in time in the same person, as can be seen above in my example.


PS: Important to add - since 2013 I took my whole 6 weeks yearly vacation on a South-Indian beach, always in the deepest Winter from middle of Jan. till the of end Feb.. Each day during 10:00-12:00 AM and 3:30-5:30 PM - 4 hours total - whole body sun-exposure daily (minus maybe about 40 minutes swimming in the ocean).
