Why Mecobalamin(co-methylcobalamin) and Hydroxocobalamin are superior forms of B12

 What is Vitamin B12 (Cobalamin)?


Vitamin B12 is an essential nutrient that plays a crucial role in many bodily functions, including DNA synthesis, red blood cell formation, and nerve function. However, the body cannot produce vitamin B12 on its own, which is why it must be obtained through the diet or supplements. Vitamin B12 supplements are typically derived from two sources: cyanocobalamin or methylcobalamin.

Cyanocobalamin vs Methylcobalamin

Both cyanocobalamin and methylcobalamin contain a cobalt ion surrounded by a corrin ring, but they have different molecules attached to the cobalt ion. Cyanocobalamin contains a cyanide molecule, which must be cleaved off and the cobalamin portion attached to something else before it can be utilized by the body. This process creates extra work for the body, making it more difficult to break down for those with certain genetic mutations. In contrast, methylcobalamin is the naturally occurring form of vitamin B12 and can be used by the body without requiring conversion. Methylcobalamin is the methylated form of vitamin B12, which means it acts as a co-enzyme for the conversion of homocysteine to methionine.

Benefits of Methylcobalamin

Methylcobalamin provides a universal methyl donor in various physiological processes, including DNA, RNA, histone, and protein methylation. Some research has shown that methylcobalamin may be better retained in the body than cyanocobalamin. Additionally, some researchers suggest the use of natural vitamin B12 forms (hydroxocobalamin and mecobalamin) instead of cyanocobalamin for long-term supplementation to avoid the accumulation of cyanide in human tissues.

Hydroxocobalamin: An Alternative to Cyanocobalamin

Hydroxocobalamin is a form of vitamin B12 that has gained attention for its potential health benefits. It is the biologically active form of B12, meaning that it has already been converted into a form that the body's methionine pathway can utilize immediately. Hydroxocobalamin is a nitric oxide scavenger that is well-tolerated and detoxifies cyanide. It has a longer half-life in the body compared to cyanocobalamin, which means it stays in the body for a longer period of time before being excreted, allowing for a slower and more sustained release of the vitamin into the bloodstream.

Genetic Predisposition to Vitamin B12 Deficiency

While inadequate dietary intake and malabsorption issues are the main causes of B12 deficiency, genetic predisposition to vitamin B12 deficiency has been demonstrated in various studies. B12 conversion can be a problem for people with MTHR, MTR, and MTRR gene mutations. Individuals with COMT defects can also be at higher risk for accumulating too much nitric oxide or peroxynitrite, which can lead to stiffness, muscle pain, brain fog, and cardiovascular problems.

The Role of Hydroxocobalamin in Chronic Fatigue and Fibromyalgia

Hydroxocobalamin, a form of vitamin B12, has been studied as a potential treatment for chronic fatigue syndrome and fibromyalgia. These conditions have been linked to low levels of vitamin B12, and some studies have suggested that hydroxocobalamin may be more effective at raising vitamin B12 levels than other forms of the vitamin. While the evidence is not conclusive, some studies have shown promising results. One study found that hydroxocobalamin injections improved fatigue symptoms in people with chronic fatigue syndrome. Another study found that a combination of hydroxocobalamin and folic acid improved symptoms in patients with vitiligo, a skin condition characterized by the loss of pigment in patches of skin. Hydroxocobalamin is a form of vitamin B12, and folic acid is a B vitamin that is important for healthy skin. The study suggested that these two nutrients may help improve the production of melanin, the pigment that gives skin its color. However, further research is needed to confirm these findings and to determine the optimal dosages and duration of treatment.

Methylcobalamin: an active form of B12

Methylcobalamin is a form of vitamin B12 that is already in a form that the body can use. It is known as a "coenzyme," meaning it helps enzymes function properly. Methylcobalamin is unique because it contains a methyl group, which allows it to participate in certain chemical reactions that other forms of B12 cannot.

One of the key roles of methylcobalamin is in the methylation process, which is the transfer of a methyl group from one molecule to another. Methylation is involved in a wide range of biological processes, including DNA synthesis and repair, immune function, and the regulation of gene expression. Methylcobalamin is also involved in the production of neurotransmitters, which are chemicals that transmit signals between nerve cells.

The potential health benefits of methylcobalamin and hydroxocobalamin

Supplementing with any of the nature bioidentical forms of B12 (methylcobalamin, hydroxycobalamin, and/or adenosylcobalamin) is preferred instead of the use of CNCbl, owing to their superior bioavailability and safety.There is a growing body of evidence suggesting that methylcobalamin and hydroxocobalamin may have a range of potential health benefits. Here are a few examples:

Methylcobalamin and neuropathy

Neuropathy, or nerve damage, is a common complication of diabetes and can cause numbness, tingling, and pain in the hands and feet. Some studies have suggested that methylcobalamin may be effective in reducing the symptoms of neuropathy. For example, a study published in the Journal of Diabetes and Its Complications found that patients with diabetic neuropathy who were treated with methylcobalamin had significant improvements in nerve function and a reduction in pain.

Methylcobalamin and mental health

Methylcobalamin has also been studied for its potential effects on mental health. A review published in the Journal of Psychopharmacology found that methylcobalamin may have antidepressant and anxiolytic (anxiety-reducing) effects in people with depression and anxiety.

Hydroxocobalamin and anemia

Anemia is a condition characterized by a deficiency of red blood cells, which can lead to fatigue and other symptoms. Hydroxocobalamin has been shown to be effective in treating anemia caused by B12 deficiency. For example, a study published in the American Journal of Hematology found that patients with pernicious anemia (a type of anemia caused by a deficiency of B12) had significant improvements in hemoglobin levels and symptoms after treatment with hydroxocobalamin.

Hydroxocobalamin and detoxification

Hydroxocobalamin has also been studied for its potential role in detoxification. It is known to be effective in removing cyanide from the body, and it has been used in cases of cyanide poisoning. Some studies have also suggested that hydroxocobalamin may have a protective effect against the toxic effects of heavy metals, such as mercury and lead. 

What are the potential side effects of taking methylcobalamin and hydroxocobalamin supplements?

Methylcobalamin and hydroxocobalamin are a both forms of vitamin B12, also known as cobalamin, that are often used in supplements. They are generally safe to consume in recommended amounts. However, taking excessive amounts of either can cause side effects, including:

  • Digestive symptoms: Consuming large amounts of methylcobalamin can cause digestive symptoms, such as stomach cramps and diarrhea.

  • Skin reactions: Some people may develop skin reactions, such as rash or hives, after taking high doses of methylcobalamin.

  • Allergic reactions: Some people may be allergic to methylcobalamin. Symptoms of an allergic reaction may include rash, itching, and difficulty breathing.

  • Increased risk of certain cancers: Some research suggests that taking high doses of methylcobalamin and hydroxocobalamin may increase the risk of certain types of cancer, such as breast and prostate cancer. However, more research is needed to fully understand this relationship.

It is important to note that these side effects are typically associated with taking large amounts of methylcobalamin and hydroxocobalamin, well above the recommended daily intake. It is important to speak with a health professional before taking methylcobalamin and hydroxocobalamin supplements to ensure that you are taking the appropriate amount.

Methylcobalamin and hydroxocobalamin supplements are generally well tolerated and have a low risk of side effects. However, as with any supplement, it is important to speak with a healthcare professional before starting to ensure that they are safe and appropriate for you.
