This 1 Vitamin Is Absolutely Crucial To Your Overall Health, But Most People Are Deficient In It

"If you're feeling foggy, sluggish, forgetful or just generally out of sorts, you might be thinking you need to prioritize sleep or get a better handle on your stress levels. But what if you're actually dealing with a nutrient deficiency? For a vitamin that isn't exactly top of mind for most people, vitamin B-12 plays a surprisingly large role in nervous system functioning and overall brain health, including supporting memory, focus, mental health, and keeping brain cells healthy."

"B-12 deficiency is more common than most people realize, affecting around 6% of Americans younger than 60 and around 20% of those older than 60, though the exact numbers vary. Many different causes can play into B-12 deficiency, including the food you eat, medications you take, and issues with absorption and your age, with older adults being more susceptible. "Vitamin B12 deficiency is one of the few reversible causes of cognitive decline," said Dr. Majid Fotuhi, a neurologist and adjunct professor at Johns Hopkins University. "Catching it early can prevent long-term brain damage and restore mental clarity.""

"Vitamin B-12 affects brain health in many different ways. It helps build and maintain myelin, which is a protective covering around nerve fibers that allows brain cells to communicate quickly and efficiently. It also helps support DNA synthesis and keeps brain tissue healthy over time. B-12 is also essential for producing neurotransmitters like dopamine and serotonin, which help regulate mood, focus and motivation. Another important role of vitamin B-12 is helping the body break down homocysteine, which is an amino aci"

Vitamin B-12 is essential for nervous system function, memory, focus, mood regulation and maintaining healthy brain cells. Low B-12 levels commonly produce forgetfulness, brain fog and cognitive slowing, and many cases are reversible with early detection and treatment. Deficiency affects roughly 6% of Americans under 60 and about 20% of those over 60, with causes including diet, medications, impaired absorption, and age-related changes. B-12 supports myelin formation, DNA synthesis, neurotransmitter production (including dopamine and serotonin), and the breakdown of homocysteine. Older adults and people with restricted diets or absorption issues face higher risk and should monitor levels.
