Is there a medical reason vitamin B-12 levels below 200 do not respond to oral supplements?

Hm, for people who have really low B-12 levels, oral supplements most often do not work - but injections do. Usually people who use B complex vitamins do not refer too high levels of energy afterwords - they are commonly used for calming down and healing the nerves, so no outburts of energy can be expected. B12 if taken on it`s own in form of injections increases the level of oxygen in the blood and in the whole body and injections have far more higher doses of B12 then any supplement you might take orally.

Oxygen in the blood is healthy, forcing adrenal glands to secrete more hormons is not wise thing to do, can make you even more exchausted.

Folic acid and B12 function together synergistically in the body. What type of B12 supplement is it? Sublingual?

Have you tried injections? Sorry about all the questions, just want to be thorough in getting the information to gain a fuller picture so I can help you. I'm also curious about digestive function.

Though you don't need to divulge here, unless you are comfortable, just observe how well you digest food, as your intestinal flora plays a vital role in B12 production and absorption, regardless of intrinsic factor levels. Overgrowth of yeast (candida, clostridia) will also affect levels of B12. The liver is also heavily involved in B12 production, so anything that effects the liver like smoking, alcohol, caffeine, medications etc can affect B12 levels.

Medications like anti-epileptics, antibiotics, hormone therapy can reduce levels. Hope this gives you some insight and if you can provide more information I would be happy to help further. Cheers, Helen :).

Hellcat:Yes I was tested for intrinsic, normal. I was also taking a regular vitamin supplement and eat veggies as well as meat everyday. I have started to take another supplement with adrenal boosters, high in B vitamins and I do seem to have lots more energy now.(within past two weeks) I have taken injections in past year for several months and had a tremendous effect on energy and feeling good though since I have stopped the B12 is going down again.

I am having a liver MRI very soon to see if there is anything in the Liver affecting things. Thanks for the all the questions, I have thought about all of these things....still looking for more answers.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
