Hello again,
Sorry I did not see your message until today! To answer your question, my understanding is that without Mg and K (and boron and vitA), vitD will not work. They are required cofactors for vitD (http://www.vitamindcouncil.org/about-vitamin-d/vitamin-d-cofactors/). So yes, I suggest taking Mg and vit K (and boron and vitA). The Linus Pauling Institute has good info on recommended daily intake of various supplements, and you can take your diet/medication into account when deciding how much of these co-factors to supplement with. With more vitD intake daily, increase co-factors as well. I've been using Ultra-Mag, which is amino-acid chelated Mg (so it can be absorbed by the body). I noticed that with the multi-vitamins like Centrum, they use Magnesium Oxide, which cannot be absorbed by the body (so it's the same as taking no magnesium). I also take Triple K, which combines K1, K2 and K3, made by Superior Source, and Triple Boron, from Source Naturals.
I just finished a three month D2 prescription (50,000 IU / wk). About half-way through my prescription, I started to feel worse, so I read more about vitamin D and started to supplement daily with co-factors (Mg, K, etc) and D3 about 1.5 months ago. My symptoms (confusion and fatigue) improved again after starting the co-factor supplement. I mostly do not notice any symptoms now. I get re-tested next week for vitD levels.
Glad to hear you're feeling better and are getting good sleep! It's frustrating that doctors seem to know so little about diagnosis / treatment; seems like your doc (like many) probably needs to read up on this so his/her other patients don't have to insist on the prescription they need!
If you're on other medications, it would be important to make sure that Mg etc are not contra-indicated; there's into online about what medications should not be combined with metals like Mg.
Good health to you in the new year!
I suffered for 18 months with anxiety, high pulse rate, depression, zero sleep (except when I was put on some serious sleep medication). My Vit D was 12 initially and doctor's did not advise me anything except 400 IU of D3 which I was anyway getting from Multi-Vit (I take Centrum 50 plus silver).
I asked doctors to re-measure my Vitamin D 6 weeks back. It was 22 and on my insisting they prescribed D2 50,000 IU per week for 2 month. After reading this forum I started taking 10,000 IU - 12,000 IU per day of over the counter D3. After six weeks, I feel marked improvement. I can sleep for 6-7 hours, my anxiety level is low, for 4 days in a week I feel 80% normal and 3 days in a week 50% normal. The days I feel well seem to be slowly going up.
I am taking mult-Vit Centrum 50 plus in addition to D3. In addition, I have blood pressure medication.
Since I continue to take D3 10,000 IU to 12,000 IU per day, I wanted to know from you whether I should add Magnesium and K2.
From your name, are you cured from vitD deficiency? Can you post a little about your experience, like time to recovery, current sense of health / well-being, and what your vitamin intake is now and how often you get re-tested, if at all?
To answer your question, I take 400 mg of magnesium daily (it's a combination of citrate, taurinate, malate, glycinate and succinate forms; sold at Ultra-Mag from Source Naturals). VitK (not sure what whether K2 or not) is part of multivit that also includes boron. Do you have a multivit or other supplements you like?
What do you take to fulfill Magnesium and K2 needs
