The Number-1 Sign You Have a B12 Deficiency Dietitians Want You to Know
As we age, our bodies find it more difficult to absorb nutrients from food. Vitamin B12 is particularly lacking in plant-based diets or vegetarian diets, as it is commonly found in animal byproducts.
According to experts, including Lisa Cimperman, R.D., and Angela Grassi, R.D., certain groups may be at risk of a vitamin B12 deficiency. At least 4% of people between 40 and 59 are lacking in the nutrient, and even more are borderline.
- Following a plant-based eating plan or being a vegetarian
- Taking metformin for type 2 diabetes or polycystic ovary syndrome
- Taking certain heartburn medications
- HAVING had weight loss surgery
- HAVING a digestive disorder like celiac disease or Crohn’s
Being too low in vitamin B12 may cause symptoms such as extreme fatigue and vision problems.
