Now they say that levels of Vitamin D over 30 INCREASES risk for cancer

Dear Dr. Ettinger,

I am so confused. Now they say that levels of Vitamin D over 30 INCREASE your chances for cancer. If I back my dose back to 2,000 IU’s a day, is that going to make my levels above 30? My co-worker, Husband, and myself just stopped taking any of it because we don’t know what to do. I always thought that levels between 50 – 70 were ideal. I take the Vitamin D (Power Vitamin D3 Liquid) that you recommended. They have also stopped suggesting that we  take multi vitamins. I never took a multi, but my Husband did until this came out. He has Parkinson’s and does very well, but we don’t want to do anything to cause harm. Is there anything safe to take in your line of supplements? I told my co-worker and Husband that I would see what you have to say because I trust your opinion. We all await what you have to say.



Whatever source said that is either wrong, misinformed or interpreting the data to fit their agenda – one of the three. Go to for all your vitamin D needs. This is where you want to go to find-out the truth about Vitamin D ., is another good source for non-biased data. Personally, I will never drop my daily dosage of Vitamin D below 6,000 IU’s (accept during summer when I surf 3 days a week w/o my wetsuit). My 6 year old daughter takes 2,000 IU’s per day. Your husband is fine with 6-10,000 IU’s a day (get routine tests for proper blood levels) and should have a blood level between 50-80. His multi is also okay as well.

Dr. Ettinger,

The IOM expressed concern about excessive intake of vitamin D. But raised the Upper Tolerable Intake Levels (ULs) (above which there is a risk of harm) for vitamin D. The UL for individuals aged 9 and older was set at 4,000 IU’s/daily, up from 2,000 IU’s daily. The IOM noted that some studies showed an increase in adverse events (including overall mortality, some cancers, cardiovascular disease, fractures and falls) at vitamin D blood levels (I.e., 25-(OH)D levels) ranging from about 30 ng/mL to 48 ng/mL (75 to 120 nmol/L). has updated this review to reflect the IOM recommendations.

This explains everything and personally I don’t believe a word of it.  It’s a government sponsored study, very prejudiced in favor of “not promoting supplements” or true health, for that matter! Study Sponsors

  • Agricultural Research Service, U.S. Department of Agriculture
  • Center for Nutrition Policy and Promotion, U.S. Department of Agriculture
  • Department of the Army, U.S. Department of Defense
  • Food and Drug Administration, U.S. Department of Health and Human Services

Marcus Ettinger BSc., DC Dr. Ettinger,

If you have been taking 6,000 of D3 with no bad effects that is good enough for me. I do trust you and Life Extension a whole lot more than anything the government says. I do know that they want to regulate vitamins and make it so you can only get them by prescription. I did not look at who did the study so what you are saying makes perfect sense. If it were going to affect the liver it should show up in blood tests. I’ll start back with my 6,000 of D3 tonight! I have read so many good things about D. I did read to take it with K which I do not do. I will take supplements over drugs any day.

I really do appreciate you being there and taking your time to answer some questions.

Have a very merry Christmas!!!!
