What Is Vitamin B12?

Vitamin B12 (cobalamin) is a water-soluble vitamin. Research has shown it to be crucial in the manufacturing of red blood cells, DNA synthesis and for good neurological function. Its role in metabolism is to help break down fats and proteins. It also is necessary for the myelin sheath, a protective layer that covers nerves and insulates them from injury.

The only natural sources of vitamin B12 are animal foods: meat, fish, eggs and dairy. It is also found in fortified plant based and supplement sources.

Vitamin B12 deficiency is common in vegans, the elderly, and people who have absorption problems. It can lead to health problems like tiredness, memory problems and nerve damage. It is also associated with neurologic disease, anaemia, energy metabolism, and mental health, which additionally highlights the relevance of it for overall endocrine status.

How Does Vitamin B12 Work?

Vitamin B12 as a coenzyme in fundamental metabolic processes. It aids in conversion of homocysteine to methionine, the reaction necessary for synthesis of DNA and which also carries a methyl group during change in gene expression. B12 also synthesizes succinyl-CoA, a step in the Krebs cycle and energy formation.

In the nervous system it sheathes nerve fibers, enabling efficient transmission of signals. Without B12, these pathways are disrupted leading to issues like poor DNA synthesis, high homocysteine levels, anaemia and loss of insulation on nerve cells. Its rich functionality reflects its value in biological research.

Research on Vitamin B12?

Critical for RBC Formation: Studies have demonstrated that vitamin B12 is crucial in the formation of red blood cells (RBC) and DNA synthesis during erythropoiesis. Erythroblasts have a high requirement for B12 for the purposes of proliferation and differentiation and its absence leads to inhibition of DNA synthesis which in turn causes erythroblast apoptosis and ineffective erythropoiesis leading to anaemia.

B12 deficiency, due to malnutrition, malabsorption or impaired transport, is common in populations who consume little animal food. Supplementation (oral or parenteral) promptly corrects B12 levels that in turn helps to support and maintain normal RBC production and the prevention of anaemia [2].

Nervous System Support: Studies have shown that Vitamin B12 has been used to support a variety of functions, including myelin sheath maintenance and the formation of neurotransmitters. Together with vitamins B1 and B6, vitamin B12 has neuroprotective and antioxidative properties in the brain and in the central as well as peripheral nervous system.

It is known that a shortage of B12 can cause neurological disorders, but extra supplementation without proven deficiency has also been found to provide benefit in conditions such as peripheral neuropathy. And its combinatorial function with other B vitamins underscores its critical role in neurological health.

Necessary for DNA Synthesis and Cell Division: Vitamin B12 plays a role in the replication of DNA and the division of cells. It serves as a cofactor for enzymes including methionine synthase and methylmalonyl-CoA mutase, essential for nucleotide synthesis and DNA methylation.

Its absence results in defective DNA replication, genetic instability and cell-cycle arrest, particularly of dividing cells. B12 also serves as an antioxidant, protecting DNA from damage by oxidants. Therapeutic potential and roles in drug delivery, as well as a target for anti-glioma treatment using cobalamin transport antagonists are also discussed.

Lowers Homocysteine (Heart Health): Research on vitamin B12 shows this nutrient is key for lowering homocysteine levels, which lowers the risk of stroke, coronary artery disease and other forms of heart disease.

Through functioning as a cofactor for homocysteine metabolism, B12 assists in the transformation of homocysteine into methionine, decreasing its levels [6]. Although evidence indicates that B-vitamin therapy, including B12 might decrease risk of stroke, especially ischemic and subarachnoid hemorrhages, the clinical trial results have been conflicting; indeed further investigation is required for assessing its cardiovascular benefits.

Energy: Vitamin B12 plays a key role in the generation of PinkDrive Body’s energy - it acts to support mitochondria function and their ability to produce cellular energy. It is a cofactor in metabolic pathways, helping with DNA synthesis and methylation. Disruption of these processes from lack of B12 in diet causes decreased eB12 production, which can result in neurological and cardiovascular problems.

B12 deficiency is difficult to diagnose early because of the time it takes for clinical symptoms to develop, and knowledge of its metabolic pathways and the proteins associated with it are essential in order to detect, treat, and maintain energy homeostasis.

Mood, Cognition, and Health: Vitamin B12 plays a role in maintaining myelin integrity, neurotransmitter synthesis and metabolism of homocysteine. Its deficiency gives rise to neurotoxic effects like oxidative stress, vascular damage, and degeneration of neurons resulting in cognitive impairments and neuropsychiatric disorders.

Although it is not likely that supplementation will enhance cognitive function or reduce depressive symptoms in nondeficient people, preventive strategies of early screening and supplementation among at-risk groups (e.g., elderly) may help to avoid deficiency-related impairment in cognitive functioning.

Supports Pregnancy and Fetal Development: Vitamin B12 is essential in pregnancy and fetal development, playing a major role in DNA synthesis, myelination as well as methylation. The gene has an essential role in placenta development where nutrient flow from the mother to the fetus must be allowed and not blocked by tumour growth.

A lack of B12 may damage placental function, raise inflammation and mess with levels of docosahexaenoic acid — all of which can potentially influence the health of mother and fetus. Since adequate B12 levels during pregnancy are critical for normal fetal growth (7), determining and correcting maternal B12 status is important.

Immune System Boost: Studies indicate that Vitamin B12 assists the immune system by preventing autoimmune disorders, fights against viral infection, including COVID-19.

Supplementation with methylcobalamin, cyanocobalamin and hydroxycobalamin have been demonstrated to be effective for lowering homocysteine levels, methylmalonic acid levels and symptoms like pain, memory loss, impaired concentration.

Although promising, more studies are warranted to clarify the optimal dosing, forms and routes of administration B12 for tailored immune support in COVID-19 as well in overall health.

Vitamin B12 FAQ's

Others Who can sell vitamin B12 Nasal Spray?

Purchase Vitamin B12 nasal spray online from Peptide Works for research purposes. It is intended for use in vitamin delivery and absorption studies. This product has not been FDA cleared or approved and is not intended for human use. Every lot is high purity, and each lot is consistent to minimize variations in experimental results.

What are the signs of Vitamin B12 Deficiency?

Anaemia due to Vitamin B12 deficiency makes you feel tired, weak and confused. It can cause pallor, a feeling of pins and needles in the hands or feet, forgetfulness and subtle mood changes. The tongue can be sore or red. These symptoms occur when the body doesn’t have enough B12 to make healthful blood and nerve cells. Identifying and addressing low B12 can go a long way in preventing future health problems.

Is Vitamin B12 Nose Spray Better Than a Pill/ Tablet?

In many cases, vitamin B12 nasal spray is better absorbed than pills or tablets. The spray passes through the lining of the nose, entering the bloodstream directly. Pills need to be dissolved and broken down in the stomach and intestines, where some B12 may not be able to be absorbed. The nasal pathway delivers B12 more quickly and consistently than the oral route of delivery, which can make it useful for absorption and delivery studies.

What are the Side Effects of B12 Nasal Spray?

B 12 nasal spray may make your nose tingle or itch, sneeze, or have a little running of the nose at the time of testing. From time to time, headache or slight dizziness follows. These are transient phenomena and generally do not require treatment. The nutrients delivery and absorption nature of vitamin are easily observed in controlled experiment by the spray.
