4.0 out of 5 stars Read the Whole BookBy J. Ashton on October 2, 2013
Format: Paperback|Verified Purchase
I am modifying my review because it was suggested that I was not following the author’s complete directions. I’m certainly willing to concede that point. Here is the original review: I took the large doses of D3 for six weeks. I stopped because I suddenly realized that my dizziness, faintness, and heart fibrillation during running or any exertion, was perhaps due to the D3. I did a Google check on the toxic effects of mega-doses, and this was one of the effects, including dark urine and urinary tract infection, which I also was experiencing. I stopped taking the D3 immediately, and within six days had no more of those symptoms. Since I am 69, I had at first attributed the heart difficulties to old age. I’m in good health and take no medicine, exercise regularly, and have low blood pressure, so I thought the D3 could (at the least) do no harm. But after these very real problems, and now that I am back to exercising without those problems, I feel that especially the elderly should be aware of the toxic effects possible with this vitamin.
Another correction: The UTI’s seem to have been related to excessive sugar, not the D3. I am now on a low-carb diet and having good effects, and if I resume the large doses of D3 (with adequate K2, magnesium, etc) I will re-post.

Why do so many people not pay attention to the author’s instructions to take vitamin K2? It boggles the mind.

Also, I cannot now find that information about the dark urine. It’s too long since I did the research. I am thinking there was another cause for that temporary thing — I drink so much water that this problem is rare.

Sorry, I didn’t see this post before -. Your suggestions are very good. I will modify my review, and check into K2, and you are absolutely correct: I did not read the whole book, and was not following it correctly. Thank you!

Hi J,
I have to echo the other responders’ advice on calcium and magnesium… most likely, your symptoms were related to a sudden increase in efficiency of calcium absorption and consequent reduction of available magnesium, rather than the Vit D directly. You said you weren’t taking calcium supplements… but just out of curiosity, do you use dairy products? (High calcium/low magnesium.)
Thanks!

Read “Vitamin K2 and the Calcium Paradox” for comprehensive background on why Vitamin K2 is critical to take with D3. There are tremendous benefits to taking K2 which make this book a good companion to the D3 book. Large doses of D3 without K2 can be very dangerous (calcium deposits on arteries and soft tissue instead of bones). Together, in combination with calcium, vitamin A, and magnesium, you get a tremendous synergy of benefits. Read the Magnesium Miracle also… You’ll begin to see how these essential vitamins and minerals work together to produce amazing recoveries in people.
