The reason I haven’t posted the optimal dose before is because I believe you need to better understand what your getting into! In my book I fully explain vitamin D3 at optimal dose and blood levels. Hopefully you have read my book and blog. As the more you understand the more comforted you will be.
To me education whether school oriented or self directed! So what is the optimal dose? It is 30,000 IU’s per day. What you want to reach is a blood and a blood level of 100 ng/ml to 140 ng/ml. Beware you medical doctor will probably freak. They were brainwashed in school that vitamin D3 is a potentially dangerous fat soluble vitamin. It is not. It is a hormone.
The problem is the lab results. Often it states levels above 100 ng/ml are potentially toxic. They are! They are when you reach 300 ng/ml and perhaps not until you reach 400 ng/ml. Not before! I fully explain this with scientific references in my book! Again reason to read it.

Should you take other vitamins or minerals with it? I believe for sure magnesium and as much as you can tolerate. In my blog posts, I can’t make this too easy, I explain omega 3s, boron and vitamin K2.

I just finished reading your book “The Optimal Dose.” Thank you so much for this information. I am only sorry it took you through such a difficult journey to learn this. I have been searching for a very long time also and trying to find the answers to my health problems and this book helps a lot. Blessings to you.

I am a little concerned because recently I’ve read that on site report about vitamin D:

> ” A 50-year-old woman in England developed hypercalcemia and acute kidney injury, with symptoms including lethargy, nausea, vomiting, headache, and high blood pressure after taking 8,000 to 16,000 IU of vitamin D daily from a supplement for four months. Her blood levels of vitamin D had reached 1,800 ng/mL at the time of her admission to the hospital. She reported that she first began feeling lethargic about two months after starting supplementation”

For me, it’s not possible to reach such a huge amount of D in blood only taking 8k to 16k of vitamin D. Clearly, something is wrong here, or she had been just taking much more doses. Or it’s something wrong with her body.

What do you think, doctor?

ps. that quotation is from paid version of consumer lab, so I can’t link it directly here.

Can up give an estimate of how long it takes to reach COBL at 30k IU OF D3?

Ps: Read and enjoyed your book. Looking forward to results assuming I don’t have the issue mentioned in your blog (VDR?). Weight is not an issure with me.

I was taking 20,000 IU daily for several months. Tested last week at 98 ng. Freaked me a little, but maybe it shouldn’t have. I’m otherwise very healthy, fit, and do take K2, Magnesium, boron, and fish oil. Have read your book, it was fantastic!
