Heart disease remains the #1 cause of death worldwide and in the U.S. Millions die each year from heart attacks, strokes, and heart failure. Trillions are spent on medications, stents, bypass surgery, and other treatments. Yet many of these approaches focus on symptoms rather than root causes. Low vitamin B12 is an often-overlooked factor that raises heart risk through simple, measurable pathways.

Vitamin B12 is needed by every cell in your body. It helps make red blood cells, keeps nerves healthy, supports DNA production, and powers energy inside cells. When B12 runs low, symptoms can show up almost anywhere—tiredness, brain fog, numbness, mood changes, or worse. Deficiency is common, often missed, and can cause serious problems if ignored.

Vitamin B12, also called cobalamin, is a vital nutrient your body needs for red blood cells, nerves, DNA, and energy. It is unique because it contains cobalt (hence “cobalamin”) and is the largest, most complex vitamin. Without enough B12, cells cannot function properly, leading to fatigue, brain fog, nerve issues, anemia, and long-term health problems.

Low-salt diets have been standard advice for decades. Magazines, medical journals, the American Heart Association, American Diabetes Association, and government agencies routinely urge people to reduce salt intake to protect heart health and control blood pressure. Two key questions remain: Is a low-salt diet helpful? Is a low-salt diet actually healthy?
