Vit D supplement with B12?

Vit D supplement with B12?

I posted on here a few weeks ago after I'd had my test results back (I've added them here in case they're useful for this post).

Everyone was really helpful & Suzie suggested I stated to take B12 - I'm waiting for some Methyl B-12 5000mcg & B-right to be delivered & I will start taking them.

The main reason I thought I had the tests is I've put around 2 stone on in two years & it will not budge. Despite having a personal trainer, who checks on my food and doing yoga and pilates each week too. I've never had problems losing weight before so what is preventing me now?

My PT mentioned about the importance of Vit D, so I did some reading and although I know a little bit of knowledge can be a dangerous thing, I have come to the conclusion I may be deficient in Vit D. The weigh piling on coincided with starting a new job & I arrive at the office at 9.30am & leave at 5.30pm, I leave the office only 2 lunchtimes a week to walk 5 minutes to my yoga class. I think it's possible I could be lacking Vit D.

My question therefore is - would I be ok to supplement with Vit D without being tested and along side the B12 supplements?

  • Justliloldme It would be best to test your Vit D level before doing anything about supplementing. Firstly to know if you need it (too high a level can lead to toxicity as Vit D is fat soluble so excess is stored rather than excreted) and secondly to know what dose to use if you are deficient, low or whatever.

    A very easy, fingerprick blood spot test cam be done at home, City Assays do one for £28 vitamindtest.org.uk/index.html

    No problems with taking D3 when taking B vits. B vits are better taken in the morning as they are stimulating, D3 needs to be taken with dietary fat.

    When taking D3 we also need K2-MK7. Vit D aids absorption of calcium from food and K2 directs it to bones and teeth rather than arteries and soft tissues. Magnesium is another cofactor we should take when supplementing with Vit D.

  • Thanks Suzie.

    I'm clutching at straws here - I know somethings not right but I just don't know what or who can help me find out!

    Thanks so much for your advice.

  • Justliloldme,

    The only way to tell whether you are lacking in vitamin D or deficient is to have a vitamin D blood test. The dose you require will depend on how low your vitD is. If your GP won't do it you can order a private test from City Assays thyroiduk.org.uk/tuk/testin...

    Have you shown your GP your thyroid results? If TSH is above the lab range used by your GP you should be treated for hypothyroidism.
