People who have been diagnosed with the following issues are more likely to have a current or pending B12 deficiency
Anything taken orally has a long and hard journey to take prior to the absorption process beginning. As oral vitamins are ingested the are emulsified withing the stomach. The stomach contains gastric acids of which are strong enough to breakdown a variety of textures and densities. The stomach / acids break the ingested items down and pass them on to begin being absorbed. All sorts of things are going on in your digestive tract from emulsifying to more acids being added from the likes of the gallbladder etc etc.... now imagine how much of the vitamin has survived that journey and remember the intestinal walls are yet to absorb the goodness and pass the unneeded waste for excretion...
B12 injections are administered via 1 intramuscular jag where 1ml of quality B12 is administered - theres no acids to fight,,, theres no prolonged absorption process... I always tell my clients to think of what happens when you are in desperate need of (e.g) pain relief in hospital... if its just a mild case of pain thats bearable but annoying yes, oral medications are given... if you are in horrific pain and desperate for a fast acting and strong analgesia then medics will administer the meds via intramuscular injection or at severest levels intravenously - they are the most direct routes for anything being absorbed into the body.
Sites we choose to use for B12 administering - alternate bicep or buttock.
This list is a general outline of signs and symptoms that you may have a B12 deficiency. In depth, the list is much more extensive however these are the most regularly reported symptoms by a high percent of B12 deficient individuals.
An initial loading phase is recommended where the client should receive an injection every second day for the duration of 2 weeks, from there we recommend an injection every 2-3 months.
If the client has recognised a benefit from the loading phase he/she may recognise by their own individual symptoms when they require a top-up.
B12 is a water-soluble vitamin. When the body recognises that it has enough B12 to function well any excess will be excreted from the system primarily via urination. For the afore mentioned reason, b12 is classed as a safe vitamin to have in your system.
B12 cannot be produced by the human body and for this reason it is important to keep the bodies levels correct.
Fat-soluble vitamins are the vitamins that are stored in the body and if they are in excess they can build up to toxic levels - examples of fat-soluble vitamins are A, D, E and K - B12 is (as mentioned) a water-soluble vitamin. Ridiculous amounts of B12 would have to be present in the human body before any issues would remotely occur.
