How to have B12
It is commonly believed that only intramuscular vitamin B12 is effective for treating vitamin B12 deficiency. In fact, in some situations oral treatment is not appropriate. Intramuscular vitamin B12 is more appropriate in cases of deficiency when there is neurological involvement and in patients with digestive disorders including, diarrhoea or vomiting.
B12 is an intricate B Vitamin to absorb not as easily absorbed as the other B Vitamins. Older adults with vitamin B12 deficiency might require weekly injections in order to restore levels to normal
B12 can be stored in the liver for a period of time, however people who have any type of digestive disorders, will not absorb enough vitamin B12 through their digestive system.
This leads to fatigue and not enough oxygen circulating the blood. Deficiency of B12 therefore will lead to Iron-deficiency
The fact that B12 plays such a key role in red blood cell production means that deficiency of this vitamin can actually cause a form of anaemia called B12 deficiency anaemia
A key building block for haemoglobin is a compound called succinylCoA, and without enough vitamin B12, we simply cannot make enough of this building block.
Vitamin B12 Overdose
Some of the symptoms of vitamin B12 overdose include itchiness on different body parts and numbness, improper heart functioning, giddiness and regular headaches.
Vitamin B12 Injection vs Supplements
Traditionally, vitamin B12 replacement has been administered intramuscularly (as an injection) because absorption through the gastrointestinal tract is deficient.
Because vitamin B12 absorption by the gut is less effective than a shot directly into muscle, a higher dose is often needed when taken orally. Over-the-counter pills in high enough doses for treatment might be difficult to find, so you might need to take three or more pills to make up your necessary daily dose.
