Vitamin D & Leukemia

Low Cloud Cover-Adjusted Ultraviolet B Irradiance Is Associated with High Incidence Rates of Leukemia: Study of 172 Countries

    Published: December 4, 2015

We know adequate vitamin D is necessary to activate T-cells which attack cancer cells. We know leukemia patients often present with very low vitamin D levels at diagnosis. I know of no study or other research showing patients diagnosed with leukemia having high vitamin D levels (>60 ng/ml). None.

I am coming to the conclusion that if I had a high normal vitamin D level, I never would have developed CML. I feel so strongly about this. It's possible given my undetected status and the fact that my vitamin D level is now maintained between 50 - 80 ng/ml that I put the CML genie back in the bottle. I won't know until I try cessation in a year or so.

I encourage anyone to chat with their healthy family members and friends on the importance of vitamin D and getting it raised to above 50 ng/ml (but keep it less than 100). Could very well minimize the risk of developing leukemia. I will never use sunscreen again. Surprisingly - because my vitamin D level is high normal, I don't burn in the sun like I used to burn (despite using sunscreen) and had low vitamin D. The sun has been around for billions of years and humans for a few million. Sunscreen has been around for less than 100 years. And sure  enough - incidence of skin cancer increased after sunscreen. Imagine that. Vitamin D synthesis in our skin is natures protection against the sun and along the way evolved into a powerful cancer preventing hormone.

Get your vitamin D level checked and raise it if below 50.

(side note: I no longer get any more colds or flu either like I used to ... I wonder why?)

Hey Suba,

I recently went for a blood workup and everything looked good but my Vit D was just over 100.  I adjusted it down 2,000 UI.  My D level was at 57 taking 6,000UI so I went to 10,000UI.  Trying to hit that 70 mark.  I had been in the sun more than normal with walks in Hermann Park and Lake Conroe Jet skiing.  I did wear long sleeve water gear.  I was surprised it went over 100.  I did the rough math and it appears each of the 1,000 ui Vit D was equal to about 15.25 with my current sun level.  I do remember the post you made about adjusting the D intake according to winter verses summer.  Will post next level in 3 months.  My PCR will be back later this week or early next week.



Make sure to take vitamin K2 along with D(3) as K2 uses D in calcium mobilization. Hard to overdose on D when K2 is available.

I hit 100 also late last year by September without knowing it (wasn't reported on my test sheets until six months later). Because I didn't know it was at 100, I kept on my routine of 10,000 one day and 5,000 the next as winter approached. My March vitamin D level was at 44 !! So even though I hit 100 taking just 5,000 per day during summer as well as getting sun, it fell back considerably over the winter (no sun) despite my taking more vitamin D. Sun exposure can make a big difference.

I learned when out in the sun, to not take any D3 supplements that day. When days are rainy (as they are today in South east Texas), I take my summer time 5,000. I am expecting my vitamin D to climb to 80 or so by stay shy of 100. Then it will fall back as winter approaches. This is a good cycle - up in summer down in winter, but always above 50 (and less than 100).

Testing is key and I am using the fact I am getting a tan now as indication of more vitamin D production naturally.
