Vitamin B12 Shots:
The main benefit of Vitamin B12 shots is that theyre rapidly absorbed from intramuscular sites of injection; the plasma level of the compound reaches its peak within one hour after intramuscular injection.
As an example, if you took a Vitamin B12 pill that contained 500 micrograms of B12 (which is more than most), then your body would (on average) only absorb about 1.8 micrograms of that B12 which is 0.3% of what you thought you were taking! This is why so many people have low-levels of Vitamin B12.
This is a shocking truth and is the single reason I decided to start taking vitamin b12 shots
Vitamin B12 Patch:
When the B12 vitamin enters your body via the stomach (through food ), acids in the stomach separate the B12 from its protein source. It then must combine with intrinsic factor cells in the stomach (this is a protein created by the body except in people with Pernicious anemia). This B12/intrinsic factor complex travels through your intestines where it is absorbed. The absorbed amount is then transported via blood plasma and stored in the liver. This process is inefficient even in healthy humans which explains why so many adults have some level of vitamin B12 deficiency.
The Vitamin B12 patch is designed to deliver much higher doses of B12 in a much more efficient manner. The greatest thing about the Vitamin B12 Patch is that it is so easy to use. The actual patch is only about the size of a dime and is placed on your neck behind your earlobe for up to 24 hours. This way you efficiently achieve higher levels of vitamin B12 in your blood without expensive visits to the doctor for painful intramuscular B12 shots.
The Vitamin B12 Patch delivers nutrients into the circulatory system by absorption through the skin. The Vitamin B12 molecules pass through the top two layers of skin (the epidermis and dermis) and are absorbed into the bloodstream through your capillaries. A special membrane controls the rate at which the vitamin passes through the skin and into the bloodstream over a 24 hour period.
Sublingual Vitamin B12:
This is the quickest and easiest way to take vitamin B12. Sublingual simply means you put a dissolvable b12 tablet under your tongue. The membranes that are underneath your tongue are stimulated by the tablet to produce saliva, which dissolves the tablet and it’s absorbed directly into your bloodstream.
