B12 helps support nerve maintenance, myelin and normal cognitive function; it does much more than support energy.
When people hear “vitamin B12,” energy is often the first thing that comes to mind. But B12 plays important roles throughout the nervous system and brain, too.
Vitamin B12 is involved in maintaining normal nerve function and supporting the formation and maintenance of myelin, the protective covering around nerve fibers. It also contributes to normal cognitive function, which is one reason B12 has become such an important nutrient to understand when looking at overall brain and nervous system health.
And just like the rest of the B-vitamin family, B12 doesn't work in isolation. Understanding what it actually does can help you look beyond the familiar “energy vitamin” label and appreciate its broader role in the body. 💙
