Vitamin B-12 is the most molecularly complex of all the essential vitamins. Its effects are wide-ranging and crucial to many aspects of your health. Though this vitamin is readily available in many common foods, disorders related to the absorption...
Because vitamin B-12 is necessary for the formation of red blood cells and for central nervous system function, B-12 deficiency leads to anemia and neurological symptoms. B-12 deficiencies have several causes. One involves a lack of intrinsic...
The medical term intrinsic factor, or IF, is a substance also known as glycoprotein. The substance helps your body absorb and use vitamin B-12. If you take vitamin B-12 as a supplement, it may include intrinsic factor, as well as iron, folic acid...
You need vitamin B-12 for forming DNA and red blood cells and for maintaining proper functioning of your nerves. This vitamin is found mainly in animal products, and, unlike most water-soluble vitamins, extra vitamin B-12 is stored for a time in...
Intrinsic factor, or IF, is an enzyme-like compound produced by parietal cells in your stomach. It is required to absorb dietary vitamin B-12 within your intestines. As people age, many lose function of their parietal cells, which reduces the...
Sublingual B12 tablets are used in the treatment of vitamin B12 deficiency. Vitamin B12 deficiency has many causes, one of which is low or absent levels of intrinsic factor, a protein necessary for the absorption of vitamin B12 from the small...
Vitamin B12 is essential for red blood cell production, DNA synthesis and cellular and tissue repair. The body does not create B12, and people must consume foods high in vitamin B12 to avoid a deficiency. Symptoms of a deficiency include diarrhea,...
Making exercise a regular habit is the first step on the road to fitness and wellness. Since adherence plays a key role in the success -- or lack of success -- in any fitness program, personal trainers and group exercise instructors dedicate a...
If you do not properly digest vitamin B-12, you are at risk for pernicious anemia and other health issues. Your body needs B-12 to form red blood cells properly and to synthesize hemoglobin. You also need it for DNA synthesis, healthy neurological...
Nutrient deficiencies prevent your body from functioning optimally. Vitamin B-12 deficiency typically occurs when your diet lacks sufficient B-12. However, in rare cases, an inherited genetic mutation prevents your body from making a protein...
The parietal cells in your stomach produce a protein called intrinsic factor. In order for you to properly absorb vitamin B-12, intrinsic factor must bind to the vitamin in the stomach and carry it to the small intestine. The villi in the small...
Vitamin B-12 absorption depends on several substances in the stomach, including hydrochloric acid, gastric protease and the glycoprotein known as intrinsic factor. Your body needs vitamin B-12 to produce red blood cells and maintain healthy...
Your body needs vitamin B-12 to produce healthy red blood cells and ensure that nerve impulses travel throughout your nervous system properly. Vitamin B-12 is the only water-soluble vitamin that your body is able to store. However, to build...
Vitamin B-12 is used to make red blood cells, but your body cannot absorb it from the food you eat without special digestive secretions. Intrinsic factor is one of these secretions. During the digestive process, your stomach lining produces...
A man's body needs vitamin B12 to make the DNA in all of your cells and to keep your nerves and tissues healthy. Vitamin B12 also works with another B vitamin, called folate, to ensure that your red blood cells stay healthy. If a man becomes...
Vitamin B12 makes DNA in body cells, keeps the nerves and tissues healthy and plays a role in the development of red blood cells. The vitamin is the only water-soluble vitamin that can be stored in the body. Adults require 2.4 micrograms of...
Vitamin B12 belongs to the group of eight vitamins referred to as the B-complex vitamins. It is water-soluble, which means that it dissolves in water in the body. Vitamin B12 plays important roles in DNA synthesis, nerve signal transmission and...
Vitamin B12 is a water-soluble vitamin that is important for proper nervous system function and healthy red blood cells. The daily recommended B12 intake for adults is 2.4 micrograms per day. Deficiencies in vitamin B12 can cause fatigue,...
Vitamin B-12, or cobalamin, is a water-soluble vitamin found in foods of animal origin and fortified cereals. It's necessary for red blood cell production, DNA synthesis and normal nervous system function. The Food and Nutrition Board of the...
Your small intestine is the longest part of your digestive tract, where vitamin B-12 and all other nutrients are absorbed. It has three parts: the duodenum, the jejunum and the ileum. B-12 absorption takes place in the last section of your small...
Vitamin B-12 is a water soluble vitamin important for proper formation of red blood cells, repair of tissues and cells and DNA synthesis, according to Lab Tests Online. Adults require 2.4 mg of vitamin B-12 per day to ensure the body functions...
Vitamin B-12 is one of eight B vitamins that make up the B complex. It plays a crucial role in helping your body produce new cells, including red blood cells, which carry oxygen and nutrients throughout your body. B-12 exists in several forms...
The human body requires the water-soluble vitamin B12 for the proper formation of red blood cells, neurological functioning and the synthesis of DNA. The recommended daily allowances for vitamin B12 are 2.4 mcg per day for both adult males and...
Vitamin B-12 allows your body to create red blood cells and keeps your nervous system functioning properly. Vitamin B-12 is the only water-soluble vitamin that your body can store, so most people do not develop low levels. While minor decreases in...
Vitamin B12 plays important roles in DNA synthesis, nerve health and the formation of red blood cells. A vitamin B12 deficiency disorder, more commonly referred to as pernicious anemia or megaloblastic anemia, occurs when there is not enough...
Anemia is a condition characterized by a lack of healthy red blood cells. Several types of anemia can develop as a result of various nutrient deficiencies. When your body cannot make enough healthy red blood cells due to a vitamin B12 deficiency,...
Several factors impact vitamin B-12 absorption, including digestive health, the source of B-12 and the dosage. While no one formula predicts vitamin B-12 absorption, research suggests that the higher the dosage, the smaller the percentage of B-12...
Vitamin B-12 is a water-soluble vitamin that plays a role in red blood production, transmission of nerve impulses and DNA synthesis. The absorption of vitamin B-12 relies on a tightly controlled series of physiological processes in your digestive...
Anemia is a condition that affects red-blood cells. Pernicious anemia occurs when your red-blood cells decrease because of a deficiency in vitamin B12. One of the primary functions of vitamin B12 is the production of red blood cells. If you have...
