What is Hydroxocobalamin?

What is Hydroxocobalamin?

Cobalamin is another name for vitamin B12, an essential nutrient necessary for proper metabolism and energy production. Hydroxocobalamin is a chemical compound with a similar structure to vitamin B12. Even though the human body doesn’t produce hydroxocobalamin, bacteria in the digestive tract are able to convert it into a usable form. Commercial and pharmaceutical versions of hydroxocobalamin also use bacteria to create large volumes of the compound for therapeutic purposes.

Hydroxocobalamin, partially identifiable by its red color, plays an integral part in DNA synthesis and supports cell replication. The compound also has an important role in the conversion of harmful homocysteine into beneficial methionine, an essential amino acid. It helps with energy production and is necessary for normal brain and nervous system function.

A Remedy for B12 Deficiency

Hydroxocobalamin is commonly used to address vitamin B12 deficiency. When the body’s stores of vitamin B12 are low, injections of hydroxocobalamin are often used to restore B12 levels. B12 deficiency is linked to many negative health effects http://www.dreddyclinic.com/forum/viewtopic.php?f=21&t=33584, including neurologic, gastroenterologic, psychiatric, and blood disorders. There’s no question it’s one of the most important nutrients our bodies require. In one case, an individual suffering from seizures and psychotic symptoms achieved a complete recovery after B12 intervention. [1]

B12 Deficiency: Causes

Whether you’re avoiding animal products http://dreddyclinic.com/forum/viewtopic.php?f=18&t=32129 or suffering from digestive or absorption issues, you may develop a B12 deficiency. Even meat eaters who constantly consume this essential nutrient may become deficient under certain circumstances. The most common causes of a vitamin B12 deficiency include:

Pernicious Anemia

Pernicious anemia http://www.dreddyclinic.com/findinformation/aa/anemia.php is when the body doesn’t absorb B12 and in turn doesn’t produce enough red blood cells. People with this condition must regularly receive B12 supplementation. Hydroxocobalamin injection has been traditionally used against pernicious anemia based on research indicating the body more readily retains it. [2] New research has suggested oral ingestion of hydroxocobalamin (or cyanocobalamin) as an alternative option for B12 supplementation. [3]

Strict Vegetarianism/Veganism

Individuals who adhere to a strict vegetarian or vegan diet http://dreddyclinic.com/forum/viewtopic.php?f=18&t=31926 may not receive enough vitamin B12. The vitamin is mostly present in animal-based foods such as meat, eggs, fish, and milk. [4] This places many health-conscious vegetarians and vegans at risk, prompting supplementation as the main avenue through which the nutrient can and should be obtained. Pregnant women who are vegetarians or vegans will also need to supplement, as a deficiency can greatly impact the fetus. [5]

Digestive Malabsorption

If the stomach or small intestine experiences functional or structural damage, the body may have trouble absorbing enough vitamin B12 (and other nutrients). People who suffer from celiac disease also have difficulty digesting gluten http://www.dreddyclinic.com/forum/viewtopic.php?f=18&t=33578 and absorbing nutrients. Some medical conditions can also prevent the stomach or small intestine from properly secreting intrinsic factor http://www.dreddyclinic.com/forum/viewtopic.php?f=21&t=33796, the intestinal protein necessary for B12 absorption.

Harmful Organisms

Unfriendly organisms in the intestines http://dreddyclinic.com/forum/viewtopic.php?f=6&t=32721 can reduce the amount of B12 available for absorption. For example, tapeworms can consume large amounts of vitamin B12, leading to a deficiency in this powerful nutrient. [6] A condition like this may lead to gastric atrophy, a chronic irritation of the stomach lining. This can result in a loss of gastric cells that produce essential digestive substances necessary for the proper utilization of B12.

Benefits of Hydroxocobalamin

In addition to remedying B12 deficiency, hydroxocobalamin can provide additional benefits to the brain and body…

Remedy for Cyanide Poisoning

In 2006, hydroxocobalamin received approval for use as a treatment for cyanide poisoning. Hydroxocobalamin binds with cyanide molecules to form cyanocobalamin, a B12 vitamer. As a cyanide antidote, hydroxocobalamin has been deemed safe and highly effective. [7]

A Migraine Remedy

Hydroxocobalamin has been identified as a scavenger of nitric oxide, an essential muscle regulator that also acts as a free radical. Too much nitric oxide can actually cause swelling and discomfort, especially in the brain. One study found hydroxocobalamin to be effective for reducing the frequency and duration of migraineshttp://www.dreddyclinic.com/findinformation/mm/migraine.php. [8]

One Final Thought

The B vitamins are necessary for nerve function, energy production, and metabolic processes inside the body. Do not risk deficiencies of these essential nutrients! If you are experiencing symptoms related to vitamin B12 deficiency, it is pertinent that you receive testing to make sure your levels are in check. If not, supplementation may be necessary until the proper amount of B12 http://www.dreddyclinic.com/forum/viewtopic.php?f=21&t=33585 has been established.

What is Intrinsic Factor?

What is Intrinsic Factor?



Intrinsic factor is the most obscure–yet the most important–glycoprotein in the human body. It has only one primary function that is essential for good health. Produced by the parietal cells of the stomach as well as the salivary glands, intrinsic factor has a brief, but very important life. Intrinsic factor is key for supporting energy, metabolismhttp://www.dreddyclinic.com/forum/viewtopic.php?f=119&t=33240, and mental health by working with one nutrient–vitamin B12.

Why Is It Important?

To understand the importance of intrinsic factor, it’s necessary to understand the importance of B12. Vitamin B12 is involved in the metabolism of every cell in the human body. It plays a key role in DNA synthesis and formation, red blood cell creation, and brain function http://www.dreddyclinic.com/forum/viewtopic.php?f=34&t=33268. The human body does not create vitamin B12 on its own, so it must be consumed from the diet. The human digestive tract may have B12-producing bacteria; however, dietary B12 is the best way to ensure adequate nutrition.

Sources of B12 include fish, shellfish, meat, liver, eggs, poultry, and dairy products http://www.dreddyclinic.com/forum/viewtopic.php?f=9&t=32518. Batabata-cha, a Japanese fermented black tea, contains large amounts of B12 which may be bioavailable to humans. [1] This tea is considered to be a vegan source of vitamin B12. Kombucha is also reported to contain varying amounts of B12. Without this essential nutrient, neurologic problems result and, if left untreated, death follows. But B12 has a problem–it cannot survive the trip through the stomach due to the stomach’s high acid content. Fortunately for us, that’s where intrinsic factor comes to save the day.

How Intrinsic Factor Works

Intrinsic factor binds to B12 when it reaches the stomach following exposure to gastric juices. Bound with intrinsic factor, B12 will survive the journey through the stomach and reach the small intestine. Once there, intrinsic factor dissolves, releasing B12 to bind with another protein, transcobalamin II, for transit through the epithelial cells and into the bloodstream and on to the liver.

What Causes the Body to Stop Producing It?

Only the parietal cells of the stomach create enough intrinsic factor to supply the body with adequate B12. When these cells are damaged, intrinsic factor is not produced and B12 goes unabsorbed. Alcoholism and ulcerative gastritis can cause parietal cell death, greatly increasing the chances of developing a B12 deficiencyhttp://www.dreddyclinic.com/forum/viewtopic.php?f=21&t=33584. H. pylori infection and Zollinger-Ellison syndrome as well as gastric bypass surgery also cause similar effects. Age may also play a role in intrinsic factor production.

The absence of intrinsic factor leads to a condition called pernicious anemiahttp://www.dreddyclinic.com/findinformation/vv/vitamin_deficiency_anemia/vitamindeficiencyanemia_1.php, or the inability to initiate intrinsic factor and B12 absorption. In some cases, pernicious anemia can be passed down through families. This is most common in individuals of Scandinavian or Northern European descent. Certain diseases such as Grave’s disease, Addison disease, and type 1 diabetes http://www.dreddyclinic.com/forum/viewtopic.php?f=29&t=33797 may increase the risk of pernicious anemia. Individuals suffering from pernicious anemia may also be at an increased risk of gastric cancer. [2]

What to Do in Its Absence?

Anyone lacking intrinsic factor will need to supplement with B12. However, since B12 cannot be digested without intrinsic factor, it needs to be administered through regular injections. Although sublingual options exist, these may not provide adequate levels of B12. Consult with your doctor to discuss the best options for you.
