What Experts Say

Vitamin B12 deficiency is common in Pakistan due to low dietary intake of animal-based foods, prolonged use of acid-reducing medicines and conditions affecting nutrient absorption. Deficiency can present as fatigue, tingling in the hands and feet, memory difficulties and low mood if left uncorrected for a long period.

Methylcobalamin is one of the two active coenzyme forms of vitamin B12 used directly by the body, unlike cyanocobalamin which requires conversion in the liver. It supports myelin sheath formation around nerves, red blood cell maturation and DNA synthesis. The sublingual tablet form allows absorption through the tissue under the tongue, bypassing some digestive breakdown.

Doctors typically confirm B12 deficiency through a blood test before starting supplementation, since symptoms overlap with other conditions. Mild deficiency often improves within a few weeks of daily use, while more severe or long-standing deficiency may need higher doses or injectable B12 under medical supervision. Vegetarians, vegans, older adults and people on metformin or long-term antacids are at higher risk and may need routine monitoring.
