Hello

[Ela23el]

Hi, can you tell me the effects of cyanocobalamin 100 mcg? I take it orally, can it make you fat?

if someone has been taking this treatment for some time

[Narwhal10]

No Ela23el,

Cyanocobalamin cannot make you fat. However, hypothyroidism and other medical conditions can affect a person’s weight and metabolism.

It is common that people with PA/B12D have other conditions like Crohn’s disease or coeliac disease. Often the general public and medics can very wrongly assume we have not got these awful diseases because we are of ‘normative weight’ or some are overweight. The gastrointestinal tract is 9 metres long. Lots can go wrong with it.

I hope you have had tests for diabetes, thyroid, coeliac disease. You do not say what symptoms you have to take cyanocobalamin.

the doctor gave me for B12D

If you are taking B12 because you are a vegan, then that should be enough. If you have pernicious anemia like most of us on this forum, you need a higher dose since only a tiny amount will be absorbed. Try at least 1000 mcg sublingual. If that is not helping enough, then you need regular B12 injections.

I'm not vegan but the doctor said to take this for 3 months and then to repeat the blood test and if it comes out low again to do injections

[deniseinmilden]

No, definitely not!

Have you been diagnosed with B12 deficiency ? If you have , and the symptoms that indicated B12 deficiency have gone , then it’s doing its job. That’s the effect it should have .

But . If you have Pernicious Anaemia ( a form of B12 deficiency) then you should have B12 injections , as the tablets will not relieve those B12 deficiency symptoms.

No , Cynocobalamin does not make you fat .

Haemoglobin A1c level (X772q) 4.8 % [4 - 5.9]

Coded entry - Haemoglobin A1c level - IFCC standardised (XaPbt) 29 mmol/mol [20 - 41] this is the result before treatment

It's a very conservative dose, its's the recommended daily single-dose maintenance supplementation if there was no other source of B12 in the diet.

In terms of correcting a deficiency, it's a very tiny amount and the only minor chance of effectiveness would be if you don't have PA and already have plenty of B12 in your diet (in which case you probably wouldn't be here).

If you have PA this supplement will do virtually nothing and even if your normal absorption is working, it's too low to quickly and safely correct a deficiency if serious symptoms exist, e.g. with neurologic symptoms or megaloblastic anemia.

MCV is the marker to look at for megaloblastic anemia but B12 deficiency can exist without anemia.

Do you have any neurologic symptoms?

What was your serum or active b12 and did the GP mention why they think the B12 deficiency might have occurred?

I have most of the symptoms there, especially the loss of appetite and weight, I lost 10 kg all of a sudden😕
