Vitamin B12 is one of the eight B complex vitamins. This water-soluble vitamin supports energy production and emotional stability as well as normal cell activity, mental clarity and the nervous system. Vitamin B12 deficiency is often caused by poor absorption of the vitamin from the stomach and intestines, it's normal site of uptake. Taking vitamin B12 sublingually—under the tongue—has many advantages over oral, nasal and intravenous administration.
Easy to Use
Taking a sublingual supplement is easy and inexpensive. All you have to do is place the vitamin B12 tablet or vitamin B12 drops under your tongue and allow them to dissolve or be absorbed into the blood vessels.
Fast Absorption
According to SublingualreportB12.com, ”research shows that sublingual intake of vitamin B12 allows faster absorption of the supplement. It will take only about 15 minutes for the drug to reach the bloodstream.” This is much faster in comparison to taking pill supplements, which entails a long process of absorption into the stomach and intestines. In addition, proper B12 absorption requires adequate hydrochloric acid production in the stomach and a substance called intrinsic factor that binds with B12 to help with its absorption in the blood. Individuals over the age of 50 have lower levels of these substances, which makes absorption more difficult. Sublingual B12 avoids this complication.
Efficacy
SublingualreportB12.com also states that “studies imply that only 1.2 percent of the vitamins are absorbed when taken orally. With the sublingual dose, the B12 is guaranteed to supply your system with 100 percent efficacy.”
Sublingual B12, even though it is water-soluble, is not as readily excreted in the urine like other water-soluble vitamins. It is accumulated and stored in the liver. Sublingual B12 is easier to absorb for individuals with Crohn’s disease or other gastrointestinal problems, as well as for diabetics taking Metmorfin, vegetarians and vegans—the later two of which do not eat foods providing vitamin B12.
Aditional Advantage
“Research is currently in the works for providing more reasons to use sublingual vitamin B12, according to SublingualreportB12.com. "A recent study shows that the sublingual form of the vitamin can help patients with Alzheimer’s disease.”
