have there been more cases of vitamin d toxicity reported in the medical literature since many health experts started recommending D dosages ranging from 2000-10000iu/day????

I am just curious because I have not been reading about an increase in vitamin d toxicity cases, even though many people have been more aggressively supplementing with D compared to 10 or so years ago.

Someone, however, must be making money off of all of these vitamin d level blood tests!!!

I would doubt that the there would be hardly any cases of vitamin D toxicity.

The increase in blood levels isn't linear, the more vitamin D you take doesn't raise blood levels as much per amount of vitamin D.

People have been out in the sun all the time centuries ago getting up to 25,000 IU a day.

However some people have had high levels without taking a lot of vitamin D, the reasons aren't clear that I'm aware of so blood testing is needed to evaluate the levels of each individual.

Has anyone read and tested very high doses of vitamin D3 as explained by Jeff t Bowles in his e-book ' the miraculous results of extremely high doses of vitamin D3 ' ?

He claims extraordinary results ,curing all his ailments within 9 months.

He buys his products from this website amongst others.

I'm about to embark on the adventure, any thoughts?


Many people are going to try it, I checked into it and just in the comment section there were many who going to give it a chance. So results should be coming in within months with personal findings.

MrGeorge, Ultra K2 appears to actually be MK4 not MK7, but it is a much higher dose than what is in Super K. My wife takes something similar called Osteo-K.

calc (8/20/2012)
MrGeorge, Ultra K2 appears to actually be MK4 not MK7, but it is a much higher dose than what is in Super K. My wife takes something similar called Osteo-K.



Sorry about that calc. MK-4 doesn't build up in the system as much as mk-7. Studies in Japan have used 15-45mg of the mk-4.

I looked for bulk mk-7 but the amounts would last a lifetime, in the kilograms.

I did read that 180 mcg is the minimal optimal amount for MK-7 but don't know how they got that number.

Could be that higher amounts of vitamin K would be needed with high dose vitamin D. The author recommends 200-300mcg IIRC.

I'm going to wait to see how the results come back from people trying this out, I'm not so brave.  Smile

Product Development provided the following reply: 

We are currently investigating the feasibility of increasing the dose of vitamin K2 in the Super K to match the dosage that is found in the Super Booster.  This will require testing, including the assessment of stability and compatibility.

My existing magnesium deficiency (which was quite severe and caused vitamin D resistance) worsened to very severe taking 5000 IU of vitamin D daily. I upped my dosage to 10 000 IU for a while but i could not raise my vitamin D levels.  A warning should be on all vitamin D supplements on the importance of magnesium when supplementing!

"Vitamin D, just like all other nutrients, works in harmony with several other nutrients to perform its many functions. Most importantly, vitamin D requires and 'uses up' magnesium to convert from supplements or sun into its active form in the blood. As such, it is a big mistake to simply take large doses of Vitamin D without taking the need for magnesium into consideration."

Know the importance of taking enough magnesium with your vitamin D:
