Why Vitamin B12 Matters More Than You Think
Vitamin B12 helps your body make red blood cells, maintain healthy nerve function, and support brain health. Unlike some nutrients, it isn’t made by the body and must come from food or other sources. Many adults get enough through diet, but certain lifestyles, age, or health conditions can make it harder for the body to absorb or maintain adequate levels.
When B12 runs low, symptoms often develop gradually. You might blame stress, aging, or lack of sleep at first. But paying attention to these subtle changes can make a real difference in how you feel day to day.
