Let’s uncover the urgent signs that your body might be screaming for Vitamin B12—and what you can do about it before it leads to lasting damage.
Why Vitamin B12 Deficiency Is Rising
In today’s world of busy schedules, fad diets, and processed food, B12 deficiency has quietly become a hidden epidemic. Studies suggest that up to 40% of adultsin the U.S. have low or borderline levels.
The risk is even higher if you’re over 50, vegetarian, or take certain medications like acid reducers or metformin. The reason? Vitamin B12 is absorbed through the stomach lining—and age, stress, and modern diets can interfere with that process.
