Vitamin B-12 is one of the basic ingredients needed in the production of red blood cells in our bodies. Red blood cells are responsible for bringing oxygen and other nutrients to our brain and all other tissues. Therefore, a person who is anemic due to Vitamin B-12 deficiency will suffer multiple health problems due to insufficient oxygen and micro-nutrient supplies. These problems include, but are not limited to memory loss, poor circulation leading to numbness of extremities (especially while sleeping), decreased organ functions leading to fatigue and inability to concentrate and menstrual problems for females.

Vitamin B-12 is the most poorly absorbed B vitamin. It's absorption takes place almost entirely in the ileum, the distal part of small intestines. It's absorption also depends on the presence of a gastric factor, called the "intrinsic factor." As a person ages, the production of this intrinsic factor is greatly reduced. In addition, older people usually have "dirty" intestines. Therefore intestinal surface available for absorption is greatly reduced. Elderly people often require Vitamin B-12 shot to correct Vitamin B-12 deficiency. Recent studies show approximately 50% or more of the supplement you take orally pass through your digestive system unabsorbed. In case of B-12, the percentage is even higher.

Sublingual B-12 (No Shot B-12) tablets are manufactured without using binders and fillers found in most supplements. When placed under the tongue, it can be quickly and directly absorbed into the blood stream, bypassing digestion.

The natural sources of Vitamin B-12 are meats, eggs, milk and cheese. Vegetarians who exclude eggs and cheese from their diet are advised to take Vitamin B-12 as dietary supplement.
