I found out AFTER I was diagnosed with CLL that low vitamin D is a risk factor for getting CLL. I have had chronically low vitamin D even though I worked outside for half my working life. I was haphazard in supplementing the past 30 years. With recent research, I'm seeing all kinds of supposedly helpful supplements, but it gets pretty overwhelming. I have made an appointment with a naturopath to hopefully get more guidance, but they are expensive and not covered under my insurance in the US.
My condition is in the wait and see stage. My WBC count has been stable from 3 months ago, and platelets are normal. Presently I am taking turkey tail mushroom extract, a drinkable serum called Genesis Effect, an organic concoction formulated in Niagara Falls, NY., green tea extract (less than the recommended dose because it upsets my stomach, and 30,000 IU of vitamin D. I am not taking vitamin C supplements, as I only am finding conflicting reports.
