A vitamin B12 level of 100 pg/mL is significantly low, and your symptoms of numbness and tingling suggest neurological involvement, which requires prompt medical attention. It is typically recommended to start with B12 injections until your symptoms improve, followed by maintenance injections every 1-2 months. While high-dose oral tablets may be used in some cases, injections are generally preferred for neurological symptoms, as they correct the deficiency more quickly and help prevent permanent nerve damage. You should consult your doctor promptly to start treatment and determine the dosage and schedule that are suitable for you.

Yes, a vitamin B12 deficiency can lead to glossitis, which may cause a sore, red, or inflamed tongue and sometimes manifest as cuts or cracks. To help alleviate symptoms, discuss suitable dietary changes or supplements with your doctor. Regular monitoring of your vitamin levels is also recommended.

While your vitamin B12 level of 350 is within the normal range, it is on the lower side (borderline), and your symptoms may be related but are not specific to a deficiency. Taking 500 mcg of methylcobalamin daily is generally safe and may help improve symptoms over time. However, it is advisable to consult your doctor first to rule out other causes of your foot pain, such as vitamin D deficiency, anaemia, or nerve issues, and to receive appropriate treatment.

Yes, you can switch from Methycobal Tablet to Nurokind 500 Tablet, as both contain the same active ingredient, Methylcobalamin, at the same dose of 500?mcg.

From a medical perspective, Methycobal (methylcobalamin) 500 mcg is safe but often insufficient as a maintenance dose, because oral vitamin B12 absorption is limited and lower doses may not reliably maintain adequate levels after a proven deficiency; however, any maintenance dose (oral or injectable) must be individualized and prescribed by a doctor based on blood B12 levels, symptoms, and the cause of deficiency. Patients should not self-medicate or change doses on their own, as inappropriate dosing may delay diagnosis of underlying conditions or proper treatment. Regular follow-up and laboratory monitoring are essential to determine the correct maintenance regimen.

A Vitamin B12 level of 254 pg/mL is on the lower side of normal. It’s important that you do not self‑medicate. The right dose of methylcobalamin depends not only on your lab value but also on your overall health, symptoms, diet, and other parameters (such as folate, haemoglobin, or intrinsic factor) that your doctor may want to check. Your doctor will decide whether 500 mcg is appropriate or if a different dose or form (like injections) is better for you, based on your response to treatment and follow‑up tests.
