I'd also recommend the book, "The Miraculous Effects of High Doses of Vit D3 and K2..."
By Jeff Bowles.
Also "Vitamin K2 and the Calcium Paradox - How a Little Known Vitamin Could Save your Life" , by Katie Rheame.
Also the following, which seems to indicate why it is so important to take K2 with higher doses of D3:
"Laura Jones, a global food science analyst at Mintel, says recent research has revealed Vitamin K2 has much broader health benefits than previously thought, and is increasingly being seen as a bone health ingredient.
"Vitamin K1 has a relatively short half-life and is rapidly cleared from the blood and is cleared by the liver within eight hours. In comparison vitamin K2 has a longer half-life of up to 72 hours, meaning it remains biologically active in the body for longer.
"Vitamin K2 is also absorbed better by the body, and is linked to cardiovascular health. It directs calcium to the bones, and prevents it from being deposited where it shouldn't be, for example arteries and organs, where it can cause harm," she says. "
Vitamin K2 contributes to maintenance of normal bone and Vitamin K1 contributes to normal blood coagulation.
K2 found in high amounts in fish, seafood, cod liver oil, milk and dairy, cooked veg - especially soups, legumes - especially lentils.

I confess I know absolutely zero about vitamin D, other than it's the 'sunshine vitamin'. Does it have similar effects on the body to B12 deficiency? Can it be mistaken for it, or does it run hand-in-hand with it or something? God, how ignorant do I sound right now?
VERY informative leaflet, Rod, thanks for that. I don't feel quite so much like the village idiot now. I see my medication, Carbamazepine, destroys/blocks Vitamin D in the body, so looks like I might be a potential sufferer.
We are all village idiots when it comes to the human body. Patients gain knowledge through experience. Doctors gain what they think is knowledge through their education. Truth is, we all only have fragments.
Couldn't agree more, Rod. As part of my epic Greek quest to discover the cause of my illness I do a lot of research into everything and anything I can find with even a tenuous link. You wouldn't believe how many illnesses I encounter that start with the sentence "We don't know exactly what causes...", which is often followed by "there is no known cure for...". I used to feel very aggrieved when I was first diagnosed with TN because I'd been landed with a degenerative incurable disease with no known origin but I now know I am SO not alone. In actuality Western Medicine is far more ignorant and misinformed than they would have us believe.
I'm no expert but have learned a lot recently from the above book and also, "Vitamin D Revolution", Dr Soram Khalsa. Prof. Holick is an expert and has written and lectured on Vitamin D3 and there is also information on Dr. Mercola's website.
Most people believe that, if you are deficient in one, you are fairly likely to have other deficiencies and they all work better together. It seems to be the vitamin that many doctors themselves and their families are taking in higher doses !
I posted the above on the Thyroid UK site and you might find the responses interesting,
Just found this Chancery, which seems to indicate why it is so important to take K2 with higher doses of D3.

Oh Polaris, I think you are on a one-man quest to out me as a buffoon - I've never heard of K2 (or 3 or 4 or 5 or 6... either). Seriously, I knew there was a K vitamin, but I had no idea what it did. Truthfully, I still don't. You just like to dig up new things for me to research! I shall now go and do my due diligence. I hate you.
That is a really good link, thanks. It's like a potted breakdown of all the interactions and effects of vitamins. One thing it does prove, nothing works on its own in the body. Holistic every time. If only we could get Western medicine to recognise that and stop treating individual symptoms.
VitD is a steroidal pre-hormone and needed in almost every cell of your body. That's an awful lot of D People with various serious/chronic illnesses are LOW in D and that includes cancer. Statins block the efficient production of VitD - so that is possibly over 7 million in Britain taking Statins who may well be deficient/insufficient.
The above link is also interesting - indicating the prevention of various illnesses according to D levels. Of course not fully in mainstream medicine but well worth knowing about and self treating according to your result. Again it tells you how much to take on the above link....
I have Crohns as well as Hashimotos and take 10,000IU's a day
I have Hashimoto's and also take 10,000 iu a day, with a good multivitamin containing K2. Also use B12 spray. I realised I was probably deficient in D3 and B12 after reading up on both subjects.
After just a couple of months, I feel I've been given a new lease if life - so much more alive - more energy and less foggy - much improved stomach and bowel problems, etc
Just going off now to read up about K2 on my Kindle....
Thank you for your reply. I have weekly B12 injections. A little late as I only started last Easter after a rather strange turn ?? Having had a Hemi - Colectomy over 40 years ago I had not been warned about the mal-absorption of B12 without the terminal ileum Have always taken a GOOD B Complex which has obviously kept me above the bread-line but I now know that I would have been far healthier with good amounts of B12.
I also had back surgery for stenosis - but am now thinking the spinal cord has been compromised through the deficiency. Also have Tarlov cysts in the Sacrum.
All in all it's a pain - literally ! Must now and go and prepare for the yoga class I have here tomorrow morning at 9am :-)......
It's so bad that you weren't warned about B12 absorption after your operation.... I continue to be shocked at the extent of the ignorance within the medical profession when it has such a profound effect on people's lives....still more shocked that so many aren't willing to research or even learn from their patients.
On the 17th Jan there is a Greek female Neurologist giving a talk in my favourite taverna - with a meal afterwards ! Am so interested in knowing what she will talk about - B12 ? - VitD ? - Diet ? - Gluten ? - inflammation ? - blood/brain barrier ? - I wonder. The Theme of her Presentation is Alzheimers/Dementia....
I have seen too many copies of peoples blood tests here where the B12 is LOW and yet they are told - all is well.
...Rod you are absolutely right about the wine - his wine is local and GOOD ! Also they do special things for me including Liver On Coeliac UK there are downloadable charts in many languages explaining gluten ! Maybe we need one for the Thyroid
Just read this Marz in "Vitamin K2 and the Calcium Paradox, by Katie Rheame:
"Alzheimer's type senile dementia is closely associated with a well established vitamin K2 deficiency, osteoporosis.
Alzheimer's is so strongly linked to accelerated bone loss that bone mineral density in early stages of the disease diminishes in tandem with gradually shrinking regions of the brain.....an equally likely possibility is that a common factor is responsible for both bone loss and brain loss.....people with Altzeimer's consume less than half the dietary vitamin K of their mentally healthy counterparts".
Yes thanks Marz. Really good - interesting to see Wilhelmina Reitsema at the beginning of this video (she wrote in 'Responses' to the A.A. Hunt article on the BMJ site) saying the internet is your best friend and advising you to self treat with B12 if you don't have the patience to wait !
What I just don't understand is why the medical profession is not listening to all these eminent people...
PS. Jeff Bowles in his other book on Altzeimer's says that Melatonin
Very interesting links, Marz, especially that list of diseases that might be related or influenced - that's truly epic in scope. Unfortunately mine, trigeminal neuralgia, isn't on it, but MS, a potentially related disease, is, so you never know. Maybe TN isn't on it just because it's so rare no research has placed Vit D on the radar yet. Definitely going to look into this!
Vit D is my fav subject - I always feel the need to "tell the world" about it ....
and other nutrient deficiencies... So many folk do not want to listen - yet it's only sunshine, cobalt, iron - how simplistically daft (in this day & age)........ well supplementing cod liver oil is pretty old hat....but it worked.... pickle/cider vinegar/wine with meals - aperitifs.... high or low stomach acid? Smelly cheese?..
Hi Marz (waves!) - constantly reminding folk about deficiencies (we 'harp on' at lot!) - but we need stronger words - 'Life threatening conditions' actually.......
Why talk about Vit D on a B12 site?
(apart from being important too)... things work together - the body isn't chopped into parts!
e.g. My colleague's mum (with PA - apparently from 'not eating veg in Scotland') had to have an infusion of Vit D Before her B12 injections could hope to work - not seen any mention of this 'tho. (& an injection every 3 months is NOT enough).
B12 & folate with B complex - please tell me if wrong - I'm just a learner...
Vit D with A, Mg & K2 (& controls calcium)
Iron & Vit C
there's more combos I'm sure - but taking a multivit ensures completeness, insurance.
Here's a interesting (but slightly controversial) link on vit(al)min(erals) from Chris Masterjohn. J
..interesting about the D infusion before B12 jabs . Am wondering why your link was controversial ? Lots of helpful information and all in one place. Impossible to take it all in - even when my brain is working better early in the morning - did it mention that ? If so I missed it ....
I think it's important to keep introducing ( banging on about ! ) the things we are passionate about at every opportunity.
Keep up to good work - good to see you over here Bringing sunshine into everyones' lives - where are you going next ?
No I don't intend getting any other conditions, I'm just here to learn about B12 as I have neuro/sensory stuff going on (since years) - I'm trying not to supplement so I can have thorough testing, but keep falling off the wagon.
"Vitamin D is best known for its relation to calcium metabolism. By supporting the absorption of calcium from food, it prevents and cures the childhood bone disease rickets and its adult counterpart osteomalacia. It also protects against tetany, convulsions and heart failure in newborns, helps prevent osteoporosis in the elderly, prevents the development of type 1 diabetes, and is believed by some researchers to have additional roles in protecting against cancer, heart disease, high blood pressure, obesity, arthritis, multiple sclerosis and various other diseases.19"
there's a few conditions there that could be helped....
again vitamin & minerals are not taken seriously (like me ;D ) they need some 'spin'. Even GPs didn't seem to take any notice of their own Chief Medical Officers' letter about Vit D (link on my profile). J x

Marz and Sparerib got me started 
Have always taken a GOOD B Complex which has obviously kept me above the bread-line but I now know that I would have been far healthier with good amounts of B12.
Acccrete D3
Really concerned for my husband bloods reveal really low vitamin B12 and D3
For those taking Vit D supplements
vitamin overload?
