It's central to nerve health and protection, and it's essential for forming red blood cells. Beyond that, it plays a role in digestion, iron use, metabolism, and even memory and sleep patterns.
There's some indication it may support both, likely tied to its broader role in nervous system health. It's more established as essential for nerve function generally than as a targeted sleep or memory fix.
People on plant-based diets, older adults (absorption naturally declines with age), and anyone with digestive conditions that affect absorption are the groups most commonly advised to pay attention to B12 levels.
B12 helps convert homocysteine, an amino acid that in high levels is linked to cardiovascular risk, into other compounds the body uses. It's one of the more overlooked cardiovascular connections.
