Main properties and functions of methylcobalamin:
Vitamin B12, in the form of methylcobalamin, supports hematopoietic function, is responsible for the production of erythrocytes (red blood cells), and aids in DNA and RNA synthesis. This prevents megaloblastic anemia and helps avoid symptoms such as weakness, fatigue, difficulty concentrating, and pale skin. Vitamin B12 also affects the functioning of white blood cells, supporting immunity and the body’s ability to fight infections.
B12 is also essential for the synthesis of myelin , the protective sheath of neurons, which contributes to improved nerve conduction. It positively influences cognitive function, improving memory and concentration, and reduces the risk of neurodegenerative diseases and depression.
Vitamin B12 helps reduce fatigue and improves energy metabolism. Furthermore, methylcobalamin helps reduce homocysteine levels , an amino acid associated with the risk of cardiovascular disease. By regulating homocysteine levels, it reduces the risk of atherosclerosis, heart attacks, and strokes.
Natural sources of vitamin B12 are primarily animal products such as meat, fish, eggs, and dairy, so supplementation is crucial for those on a plant-based diet. Methylcobalamin supplements are also recommended for older adults, as their ability to absorb this vitamin decreases with age.
Recommended Dosage and Safety – Methylcobalamin supplementation should be tailored to individual needs, typically in doses ranging from 500 to 1,000 µg daily, under the supervision of a physician or dietitian. Vitamin B12 is safe and does not accumulate in the body, as excess is excreted in the urine.
