Neurologist Warns: Vitamin B12 Supplements Can Mask Serious Issues
15 Nov
Summary
- Numbness and tingling may not always signal B12 deficiency
- Supplements should only be taken under medical guidance
- Deficiency can cause fatigue, weakness, and memory problems
On November 15, 2025, Dr. Rahul Chawla, a neurologist trained at AIIMS in New Delhi, warned against taking vitamin B12 supplements without proper medical guidance. Dr. Chawla, who is a consultant neurologist at IBS Hospital in Lajpat Nagar and the founder of HealthPil.com, explained that numbness and tingling are not always signs of a B12 deficiency, and may instead indicate other underlying issues.
The neurologist stressed the importance of checking B12 levels before starting supplements, as a deficiency can cause fatigue, weakness, pale skin, dizziness, and even memory problems. However, he cautioned that taking supplements without testing can mask the real cause of symptoms, interfere with other nutrients, and often provide only trace amounts of B12 - far too little to effectively treat a deficiency.
Dr. Chawla outlined that the appropriate daily dosage to overcome a B12 deficiency is 500 to 1,500 micrograms, while most supplements contain only 15 micrograms. He urged people to consult a doctor before self-medicating, as numbness and tingling can also be signs of nerve compression, diabetes-related issues, or early neurological problems.
