Nerve pain, burning sensations, and loss of sensation in the feet are often attributed solely to aging or diabetes. However, research shows that Vitamin B12 deficiency is frequently associated with sensory and motor nerve dysfunction. In this video, you’ll gain a clear understanding of how Vitamin B12 supports nerve structure and signaling, why long-term metformin use or acid-reducing medications may increase the risk of deficiency, and how maintaining adequate levels may help preserve neurological function.
By examining peer-reviewed studies and clinical evidence, this discussion connects the science of B12 metabolism with real-world nerve symptoms—helping you better understand the role this essential nutrient plays in overall nerve health.
