Vitamin and anxiety query

Posted , 3 users are following.

Hi everyone. I have posted this in the vitamin forum but hoping for more luck here due to the nature of the topic. It's a bit obscure but here goes...

I have arranged to have a blood test to essentially cover ruling out any link between vitamin deficiency and my anxiety, notably Vitamin B12, Magnesium and Full Vitamin D. As it stands, I am on vitamins which contains all of these...would anyone have a rough estimate as to how long roughly it takes for these to get out my system? I don't want to do the blood test with artifically higher in my system due to the vitamins, only to then therfore see my results are normal and not knowing for 100% if it's due to the vits or not! I'm keen to know as I'm off all vitamins at the mo as a result and am having low level anxiety about whether I'm doing the right thing or not!

Any answers would be much appreciated.

Ps. I'm on chamomile as well to relax me, but seen it contains magnesium stearate...without sounding dumb, is this basically magnesium?

Many thanks

    Hi DBE. ....I have to be honest here, I've ran the gamut of every possible vitamin, multi-vitamin and herbal teas I can care to mention.

    I've tried b12 patches, magnesium oil spray. In my honest opinion none of them worked for me,

    except where I took double the recommended daily dose of b12 where I felt it gave me more energy and a more positive mood.

    I know it says never exceed the recommended daily amount but I tried due to my anxiety getting out of hand.

    In my honest opinion it's trial and error with vitamins and herbal remedies, but you never know you might find something that works for you.

    Take care

    I'm interested in the tests as was considering getting them done, are you getting them through GP or privately?

    I'm still unsure if there may be a physical cause for my anxiety but know I have health anxiety and blood tests will probably not show anything, but it is hard not knowing for certain. If nothing else I would like to rule it out as it would be a mistake to overlook something that could be treated easily and make a big difference.

    Different vitamins stay in the system for different lengths of time, as some are fat soluble and would remain for longer, whereas others are water soluble and are passed in urine . I had a quick look on google and was suprised to see that after taking supplement that vitamin D levels can remain raised for around a month, and B12 although water soluble can be stored in the liver for months.

    Magnesium stearate is used as a filler in many tablets, it is a form of magnesium but it depends on how much is in them and I'm not sure how well it is absorbed as different compounds are used magnesium supplements eg. magnesium citrate.

    I would stop taking vitamins for at least a week, preferably longer, before the tests.

    Thank you all for the replies.

    My doctor was reluctant to do so, but I asked whether there was first a Serotonin test (I googled it, apparently there's a serotonin platelets test?) However I was told that, well, in this country at least, such a thing doesn't exist except on post mortems (needless to say I passed, haha)

    When I suggested I knew of a magnesium defficieny test she agreed, and on the form also is for B, and full Vitamin D. Maybe I just got lucky, but like I say I don't think it's something GPs are thrilled at doing. There's a chance I'm on a wild goose chase of course but I'd rather rule it out for certainty!
