Vitamin B12 Methylcobalamin Powder

Methylcobalamin(Mecobalamin), also called MeCbl, Methyl B-12 or Methylated Vitamin B12,  is the only endogenously coenzyme form of Vitamin B12 with biological activity. Unlike commonly available cyanocobalamin and hydroxocobalamin, it requires no metabolic conversion in the liver and can be directly absorbed and utilized by human cells after intake. As an essential core raw material, methylcobalamin is widely applied in pharmaceutical manufacturing, high-end health supplements, special medical foods and pet nutrition products.

Healthkintai^® is a professional raw material supplier specializing in this field. We mainly offer Vitamin B12 Methylcobalamin Powder with a purity of ≥98%. Our product features excellent water solubility, stable chemical properties, high temperature resistance and good compatibility. It complies with national and industrial testing standards, with complete qualification documents, sufficient in-stock supply and sample support available. Contact us at health@kintaibio.com now.

Vitamin B12 is the general term in nutrition, and its chemical name is cobalamin. Both refer to the same category of cobalt-containing water-soluble vitamins. Cobalamin has several common subtypes, mainly including cyanocobalamin, hydroxocobalamin, adenosylcobalamin and methylcobalamin. Among them, cyanocobalamin and hydroxocobalamin are the most prevalent forms found in foods and regular supplements. They cannot function directly after intake and require multiple metabolic conversions in the human body, first turning into adenosylcobalamin and ultimately methylcobalamin. As the primary biologically active form of cobalamin that can be utilized directly by the body, methylcobalamin needs no further metabolic transformation and boasts a higher absorption rate.

Both methylcobalamin and cyanocobalamin are forms of vitamin B12, an essential water-soluble vitamin for the human body, with identical core functions: participating in erythropoiesis, maintaining nervous system health, and promoting homocysteine metabolism. The biggest differences between the two lie in their chemical structure, active form, absorption and metabolism, indicated populations, and safety profile.

Japan (PMDA)

In September 2024, the world's first high-dose mecobalamin injection was approved in Japan for the treatment of amyotrophic lateral sclerosis. Mecobalamin tablets and injections have long been approved for peripheral neuropathy and megaloblastic anemia in the country, and are covered by medical insurance. All products comply with the requirements of the Japanese Pharmacopoeia.

United States (FDA)

As the active form of Vitamin B12, mecobalamin can be marketed directly as a dietary supplement in the United States without special approval. Products may be labeled with claims relating to nerve care and red blood cell formation. The market is dominated by oral dietary supplements, while injectable products are only available through compounding pharmacies at relatively high prices.

European Union

Under applicable regulations, mecobalamin is recognized as a qualified source of Vitamin B12 in the EU. It is permitted for use in common foods and infant formula, with specific dosage limits specified. Oral and injectable formulations are only approved for peripheral neuropathy and anemia. To gain market access, raw materials must obtain a Certificate of Suitability to the European Pharmacopoeia and comply with international quality standards, with strict control over heavy metals and residual solvents.

• ·Cyanocobalamin produced by microbial fermentation is used as the starting material.
• ·Methylcobalamin crude product is synthesized via reduction and methylation under nitrogen protection and light-shielded conditions.
• ·Purification is completed by pH adjustment, concentration, repeated crystallization and column chromatography to ensure high purity.
• ·The crystals are dried under vacuum at low temperature, then crushed and sieved to obtain methylcobalamin powder.

Methylcobalamin for B12 Deficiency

Methylcobalamin is the active form of vitamin B12. It requires no secondary conversion in the liver and can directly participate in the human methylation cycle and folate metabolism pathway. For individuals with vitamin B12 deficiency, it rapidly replenishes active coenzymes and works with the MTHFR enzyme to convert homocysteine into methionine, thereby reducing blood homocysteine levels. Meanwhile, it supports the synthesis and repair of nerve myelin sheaths, relieving nerve damage, numbness in limbs and fatigue caused by vitamin B12 deficiency. It also facilitates normal red blood cell production to correct megaloblastic anemia. Compared with conventional cyanocobalamin, methylcobalamin is better suited for people with impaired folate metabolism and MTHFR gene variations, featuring faster efficacy and a lower metabolic burden.

Methylcobalamin for Cyanide Poisoning

Cyanide ions feature strong affinity and competitively bind to iron ions of cytochrome oxidase in cellular mitochondria, blocking electron transport and aerobic respiration, which leads to tissue hypoxia and cellular asphyxiation. Methylcobalamin contains an active methyl-cobalt coordination structure that rapidly binds to cyanide ions in the body to form non-toxic and water-soluble cyanocobalamin. This stable complex no longer interferes with the respiratory enzyme system and is eventually excreted via urine. It relieves the inhibition of key enzymes by cyanide ions, restores normal cellular respiration and metabolism, and thus achieves the detoxification effect.

Methylcobalamin for Cats and Dogs

Methylcobalamin offers a wide range of vital benefits for dogs and cats.

·Firstly, it effectively sustains nervous system health and alleviates nerve degeneration, limb numbness, unsteady gait, tremors and cognitive decline caused by aging, metabolic disorders or trauma.

·In terms of hematopoietic function, methylcobalamin participates in folate metabolism and red blood cell synthesis, boosts the oxygen-carrying capacity of blood, relieves anemia-related symptoms such as listlessness, general weakness and pale mucous membranes, and maintains normal blood circulation in the body.

·Meanwhile, it takes an active part in the metabolism of fats, proteins and carbohydrates, improves gastrointestinal digestion and absorption, protects intestinal flora and gastric mucosa, and eases poor appetite, indigestion and emaciation. Proper long-term supplementation can also enhance the overall immunity of dogs and cats, playing a positive regulatory role in daily health care, care for senior pets, as well as physical recovery after illness or surgery.

In the Pharmaceuticals

As the core application for mecobalamin, medicine leverages the pharmacological properties of active vitamin B12 to develop a variety of pharmaceutical formulations, covering oral, injectable and external administration routes. Mainstream products on the market include mecobalamin tablets, dispersible tablets, capsules, oral solutions, injections and mecobalamin creams.

In the Dietary Supplements

Methyl B-12 is widely used for gentle nutritional supplementation, nerve care and sub-health conditioning, with dietary supplements as the predominant product type. Common products include single-ingredient mecobalamin nutrients, compound B-vitamin tablets, nerve-care compound soft capsules, portable strip-shaped nutritional powders, compressed candies and portable oral liquids. Most products are formulated with folic acid, oryzanol, phosphatidylserine and other ingredients.

In the Food and Beverages

As a food-grade nutritional fortifier, mecobalamin is widely incorporated into a wide range of conventional and functional foods. Its application covers functional energy drinks, sugar-free tea beverages, ambient-temperature dairy products, fermented yogurt, breakfast cereals, meal replacement shakes, solid beverages and nutritional snacks. During production, mecobalamin is added in compliance with national standard ratios to make up for the insufficient vitamin B12 content in ordinary foods.

In the Pets' Supplements

For the daily nutritional care of companion animals such as dogs and cats, the current market offers dedicated pet products including single-dose mecobalamin tablets, nerve repair tablets, oral nutrient solutions, compound nutritional pastes, B-complex vitamin granules and functional dietary freeze-dried treats. These products are available in single-ingredient functional formulas and multi-nutrient compound formulas, usually blended with folic acid, taurine, multi-vitamins and other ingredients.

For conventional oral tablets, capsules and dispersible tablets, the single adult dose is 0.5 mg. For daily nutritional supplementation or mild vitamin B12 deficiency, take it once a day. When used to treat megaloblastic anemia and peripheral neuropathy, take it three times a day, with the total daily oral dose not exceeding 1.5 mg.

Injectable formulations must be administered by professional medical staff in medical institutions. The standard dose is 0.5 mg per administration, 2 to 3 times a week.

Elderly patients may follow the adult dosage, and it is recommended to start with a low dose. For children, pregnant and breastfeeding women, the dosage shall be adjusted by physicians according to age, body weight and physical condition; do not take the medicine without medical advice. If symptoms show no improvement after one month of continuous medication, discontinue use and seek medical re-evaluation promptly.
