Doctor’s guide to vitamin B12 supplements: Try 8 top-rated picks to support energy and nerve health

Low on energy or focus? A doctor explains how vitamin B12 supplements can support nerves, stamina, and daily vitality.

A vitamin B12 supplement often becomes essential when persistent fatigue, weakness, memory lapses, or tingling in the hands and feet begin to affect daily life. These symptoms are usually overlooked because they frequently indicate low levels of vitamin B12. This vitamin is vital for red blood cell production, DNA synthesis, and maintaining myelin, the protective covering around nerves that supports proper nerve signalling.

Dr Sanchayan Roy, Senior Consultant in Internal Medicine at Apollo Spectra Hospital, New Delhi, tells HealthShots that factors such as poor dietary intake, digestive disorders, and long-term medication use can impair B12 absorption over time. In such cases, selecting the right B12 supplement helps restore levels effectively, supporting energy, nerve health, and overall metabolic function in a safe and targeted manner.

Benefits of vitamin B12 supplementation

Adequate vitamin B12 levels support brain function, improve concentration, and reduce some nerve-related symptoms, such as numbness and burning sensations. It also helps prevent anaemia, supports heart health by regulating homocysteine levels, and contributes to healthy hair, skin, and nails. The expert says B12 supplementation is particularly beneficial for improving energy levels in individuals with a deficiency, rather than acting as a general stimulant.

Vitamin B12 dosage and safety

B12 supplement needs can vary widely. Most adults are advised to take doses ranging from 500 mcg to 1500 mcg, depending on the level of deficiency, absorption issues, and medical history. Dr Sanchayan recommends a blood test to check B12 status before starting higher doses, especially for long-term use. Be cautious of products promising an “instant cure” or overnight energy boost; accurate B12 correction takes consistency and clinical guidance, not exaggerated claims or unnecessary megadoses.
