According to research conducted in 2008, 1,000 micrograms of vitamin B12 is available in the body only 1.3%. Able to absorb. On the other hand, the same amount of Vitamin B12 injection The absorbing rate has been found to be between 55% to 97%.

Vitamin B12 level increases quickly with injection
Since Vitamin B12 tablets enter the body like injections. They are not absorbed, so it is necessary to take them daily.

Medicines have to be taken for 3 to 6 months, but injections increase the level of Vitamin B12 quickly.
