An
analysis of the usefulness of Vitamin B12 injections for bodybuilding
Vitamin
B group and in particular Vitamin B12 (Cyanocobalamin) injections have been a
long-standing practice among Mauritian bodybuilders and athletes around the
world for its publicised ergogenic benefits in terms of performance, boost in
oxygen capacity and metabolism. B12 injections, in addition to being very
painful because of an alcohol base preparation are administered far in excess
of daily recommended amounts. Common dosages of B12 injections are about
5000mcgs per shot, representing about 1000 times the recommended daily
allowance for the average healthy individual.

Vitamin
B12 is not new to the bodybuilding supplements industry as I remember that
during the early to mid-90s Vitamin B12 had a short stint on the shelves as a
very potent steroid-like anabolic agent especially in the form called Coenzyme
B12 or Dibencozide. It was more hype as B12 rapidly faded from the bodybuilding
supplements market. It however remained quite popular among endurance athletes,
wrestlers and some bodybuilders.
Vitamin
B12 injections were generally intended for those having problems absorbing the
vitamin from the stomach. Remember that the absorption of oral B12 takes place
in the mouth and ends in the stomach. A protein called “Intrinsic factor” is
needed for B12 absorption and this protein is sometimes not produced in certain
people. Furthermore, vegans sometimes resort to B12 supplements because their
food choices are quite poor in B12, a vitamin found primarily in animal-based
foods (see picture). Some people also develop absorption problems because of
stomach bypass surgery and stomach complications like gastritis and therefore
taking gastric medications like Omeprazole. For such people B12 injections are
definitely warranted because injections go directly into the blood stream,
bypassing the intrinsic factor issue. Keep in mind that in some cases B12
injections are also used to treat chronic fatigue syndrome.

Much
of sports performance and metabolic boosting effects of B12 in athletes come
from athletes who were already deficient in the first place, notably vegan
athletes. In such athletes supplementation through tablets and injection
brought about a good effect. In numerous studies, supplemental B12 provided no
additional benefit in the absence of any nutritional deficit of the vitamin
(1). Because B12 is involved in red blood cell production (erythropoiesis),
endurance sportspersons use it. It doesn’t work if they already have normal B12
levels. Indeed, in many instances B12 provides a mental boost which is a huge
performance enhancer itself. There is a huge psychological dimension to sports
supplements.
Similarly,
B12 injections are being promoted as a weight loss product. Bear in mind that
B12 is not involved directly in the fat burning process but rather as an
extrapolation of its function in maintaining healthy metabolism. If B12
promotes a healthy metabolism it does not mean that taking megadoses will
increase metabolism even further to make you ripped and give you more energy.
Very often supplement companies use such doubtful extrapolations to sell you
products. Again, if ever a metabolism boosting effect was seen it would be in
those deficient in B12 in the groups mentioned above and not in individuals
with normal levels.
Summary and take-home
message
- v B12 is involved in many vital processes like red blood cell production and energy systemsv B12 is often deficient in vegans and those with the above-mentioned stomach problemsv If you want to know your vitamin B12 status a visit to the medical laboratory may be helpful. Biochemical tests for B12 status include blood tests for parameters like (hematocrit, hemoglobin, and erythrocyte indices), serum or plasma vitamin B12.v If you need to take B12 and don’t have any stomach problems, take tablets or even better resort to food sources.v Positive effects of B12 on metabolism and performance were seen in deficient athletic populations and not in people with healthy B12 levels.v B12 injections are painful. If you love pain, do squats until you drop.
Vitamin B12 injections are quite a pain in the ass

Well all in all we shouldn't forget to get all vital minerals and vitamins, not just protein, i think it's better to choose to eat low fat meat, milk products, tofu, salmon, in the worse case cheap whey protein, canned tuna... instead of spending huge amount of money for medicine after ruining immunity with all the chemicals - "food supplements". Bu still i like bodybuilding and sometimes use sport supplements, but am afraid of their negative effect on immunity...
