B12 deficiency

I was told in December 12th I am vitamin b12 deficiency and peri menopause.. I had 5 injections for 5 weeks.. next one is April 8th.. my question is can i take sublingual tablets or spray while I'm waiting for my 3 monthly injections.. im feeling lightheaded is that peri menopause or b12 deficiency.. my reading was 160 for b12 deficiency in December.. I have tingling in my fingertips but that's starting to go away.. sometimes it don't feel like I'm lightheaded it's hard to explain the feeling

You can't overdose on B12 so you can supplement without fear.

I find that I supplement even on days when I have a shot because my symptoms come back really quickly.

I'm per-menopausal as well and say that coping with hormonal changes is definitely much easier for me if I keep my B12 levels high.

You might want to think about supplementing other B vitamins as well - particularly folate as you need that to metabolise and use B12 ... but be careful about B6 - you can overdose on high levels of B6 - leads to neurological problems.

It is quite possible that 3 monthly is just too infrequent for you - that wouldn't be uncommon.

That out to be okay.

It might be worth talking to your doctor about NICE guidelines if you are in UK as recommendation is maintenance 2 months if there is neurological involvement and the tingling would be neurological. However, even 8 weeks may not be frequent enough


Ok I have a doctor's appointment today at 10 to 3.. I'm in Ireland


Hi yes it is. I too have tingling in hands and feet and some other neurological problems and I need to take sublinual b12 as the 8 weekly jabs would not control these symptoms.


I have tingling in fingertips.. I have the doctor today at 10 to 3.. I'll speak to him.. I'm going to him because I'm lightheaded also I'm suffer peri menopause


Not sure if this helps or if you are interested but I recently heard about a new oral prescription alternative to the injections called Eligen B12. I recently read that it works even if you don't have intrinsic factor (so even if you don't have normal gut absorption). Apparently it came out a month or two ago


Dear me Charlotte, why so many same post?

Its not new:


As mentioned to your numerous other responses; I called the company to find out what you were referring to; you are right, the name Eligen B12 was out there before, but there was an Eligen B12 100 mcg, not 1000 that was put on the market with a company called Life Extension. The company then decided because it was going to go prescription medical food that it would only develop the Eligen B12 1000 mcg and it withdrew the 100 mcg from the market so there would be no confusion. The 1000 mcg is for clinically deficient patients instead of an injection. This one was just recently launched in March, which is why I was just hearing about it...


Thank you Charlotte. . That's interesting


You're welcome mortyhugh1971


At least research is been done.. Martina that's my name


I agree, Martina


I am same as you. I'm dizzy all the time , I also have hypermobility, I get my jag every 8 weeks as by week 7 I'm in a mess. I never even knew there was a spray, I've heard of tablets and someone I know takes them as well as her jag .i think best to ask pharmacist.
