Vitamin B12 & Thorne Research B Complex help!

I currently have low levels of B12 and it has been suggested on here that i take 5000mcg a day and also to take a B Complex.

I just wanted to know, as B Complex has 600mcg B12 included...should i take a lower dose of B12?

i have also seen a Thorne Trace Minerals which includes Zinc, Chromium, Selenium etc would that be worth taking too?

  • Nope.

    You need to get your serum levels up asap. Excess B12 will be excreted in your urine.

    The only time you shouldn't take ANY supplements is if you have liver or kidney disease.

    Edited to say: The vitamin B12 from the complex tablets are absorbed in your intestine and if you have bowel issues it won't be absorbed. While most of the lozenges should bypass your intestine to get absorbed.

  • I have fat in my Liver...is that the same thing? I do have problems with my bowels also. my doctor isn't sure if its IBS or something else and have an appointment to see a specialist on the 5th September. I also have overflow diarrhoea/Chronic Constipation. (sorry for the tmi).

  • It's common if you have thyroid problems to have bowel issues. Get your thyroid hormones plus vitamins and mineral levels all optimal and it should go away. In addition if you have Hashimoto's you should go gluten free.

    In regards to your liver where you told you couldn't take ANY medication?

  • I don't have to take any meds for my Thyroid atm as it's subclinical and although my TSH is suppressed my FT3 & 4 are within range. I've only had my Iron, B12, Vit D, Folate, Sodium, Calcium and Potassium checked and all were out of range except the Cal, Pot & Sod. I have a feeling that a lot of my vitamins & minerals are too low but i'm not allowed to be tested for them on the NHS and i can't afford to go private....It feels never-ending :(

  • Forgot to say that i haven't been told by my doctor that i can't take any medications.

  • Then you can take the vitamin supplements.

  • Doing tests on other vitamins and minerals is not worth it even if you can afford to go privately.

    This is due to how the body deals with some vitamins and minerals. For example with magnesium the body only allows a tiny amount to circulate in the blood stream so there is no point doing a blood test as won't tell you whether other tissues such as muscle have enough.

  • Oh and don't bother taking the trace minerals. Concentrate on getting your vitamin B levels up.

  • How low are your levels of b12? Have you had folate and ferritin tested as well?

  • I have had all 3 tested although the Ferritin has been a while. I need to go for another blood test to see what the level is of that one and a couple of others but the B12 & Folate were done on the 21st June and the B12 was 302 and the Folate was 2.90.

  • Firstly that b12 is very low, secondly is the folate 2.9 or 29?

    Have you considered injections for b12 /Privately? The NHS won't offer them at that level but it's very low. You should be aiming for the higher level of your lab range to be optimal and your ferritin is important for your thyroid function.

  • On the hospital letter it shows as 2.90

    I didn't know you could have them as injections but i'm terrified of needles so i think i prefer the tablets.

    The results from my last Ferritin blood test were within range although not optimal level but i will be re-testing next week.

  • Yes the injections are more effective at getting in the bloodstream than sublinguals but if you don't like jabs then they are not for you. But taking supplements will give a false blood reading so be mindful of that. Good luck 👍

  • Do you know of anyone who does them in the uk as I can only see the ones you do yourself? Thanks for your help! 🙂

  • There is a chain of clinics over Europe and lots in uk - even one in Ibiza !! I will pm you name of it as I'm not sure if this is private or on the forum I'm new 👍
