Do I need k2 now I've been prescribed D3?

Hi everyone. Just had an appointnent to discuss blood test results with my gp. He has prescribed me D3 loading dose of 50,000iu, one tablet a week for 6 weeks, as my vitamin d level was 14. He has also prescribed 6 vitamin b injections, every two days for the next two weeks.

My question is whether I should buy vitamin K2 to take with my D3, as I keep reading these should be taken together.

Thank you for any advice 😊

My question is whether I should buy vitamin K2 to take with my D3, as I keep reading these should be taken together.

Yes. Also magnesium.

Doctors don't know, because they're not taught much about nutrients, but there are important cofactors needed when taking D3. You will have to buy these yourself.

D3 aids absorption of calcium from food and Vit K2-MK7 directs the calcium to bones and teeth where it is needed and away from arteries and soft tissues where it can be deposited and cause problems such as hardening of the arteries, kidney stones, etc. 90-100mcg K2-MK7 is enough for up to 10,000iu D3.

D3 and K2 are fat soluble so should be taken with the fattiest meal of the day, D3 four hours away from thyroid meds if taking D3 as tablets/capsules/softgels, no necessity if using an oral spray.

For Vit K2-MK7 I like Vitabay or Vegavero brands which contain the correct form of K2-MK7 - the "All Trans" form rather than the "Cis" form. The All Trans form is the bioactive form, a bit like methylfolate is the bioactive form of folic acid.

Magnesium helps D3 to work. We need magnesium so that the body utilises D3, it's required to convert Vit D into it's active form, and large doses of D3 can induce depletion of magnesium. So it's important we ensure we take magnesium when supplementing with D3.

Magnesium comes in different forms, check to see which would suit you best and as it's calming it's best taken in the evening, four hours away from thyroid meds if taking magnesium as tablets/capsules, no necessity if using topical forms of magnesium.

The Vit D Society and Grassroots Health recommend a level of 100-150nmol/L, with a recent blog post on Grassroots Health mentioning a study which recommends over 125nmol/L. Your GP wont know this, all they are concerned about is raising your level to reach the "adequate" category which is usually 50nmol/L +.

It is important that your Vit D level is retested after the loading doses because you need to know that level to work out what dose to continue with. If your GP wont do this then please do this test yourself (details below).

Once you've reached the recommended level mentioned above then a maintenance dose will be needed to keep it there, which may be 2000iu daily, maybe more or less, maybe less in summer than winter, it's trial and error so it's recommended to retest once or twice a year to keep within the recommended range. This can be done with a private fingerprick blood spot test with an NHS lab which offers this test to the general public:

Hi I have found an amazing d3 protocol that has helped me and so many others. K2 with mk7(take note if thyroid issues need a special k2) should be taken with vitamin d3. It helps transport calcium to the proper areas of your body. If not on k2, D3 can take calcium from your bones deposit calcium in joints and areas that will cause pain. Also D3 is a fat vitamin and needs to be taken after breakfast with at least 14g of health fats. Also D3 soft gels in olive oil/coconut oil are a better for us. Check out vitamin D wellness group on fb also Susan Rex Ryan.
