A vitamin B12 shortage can present in a variety of ways, and the signs are not always visible. Common symptoms include exhaustion, brain fog, and low mood; however, it can also cause physical and neurological disorders such as: Tingling or numbness in your hands, feet, or legs difficulty walking or balance difficulties
A swollen or irritated tongue.

Jaundiced skin. Paranoia or hallucinations. Weakness or Anemia Because B12 is essential for nerve function and red blood cell synthesis, these symptoms should not be overlooked. Why is vitamin B12 so important? Vitamin B12 is a nutrient that the body cannot manufacture on its own, therefore you must receive it through diet or supplements. It is particularly crucial for energy synthesis, red blood cell creation, and neurological function. According to studies, approximately 40% of North Americans are deficient in this vital vitamin, with rates significantly higher among those with chronic fatigue syndrome or fibromyalgia.

Testing for B12 deficiency. Determining whether you have a B12 deficit is not always easy. While serum B12 tests are widely used, they do not assess how effectively your body uses the vitamin. Ask your doctor about an intracellular B12 test to get a more accurate diagnosis. If that is not accessible, tests for Methylmalonic Acid (MMA) and Homocysteine levels can provide additional information.

What causes a B12 deficiency? This inflammatory disorder destroys stomach cells that produce intrinsic factor, a protein required for B12 absorption. Without intrinsic factor, your body struggles to absorb vitamin B12 from food, resulting in a deficit.

Leaky gut syndrome. Gluten sensitivity, bacterial infections, or a high sugar intake can all impede your ability to absorb nutrients, including vitamin B12. Improving gut health through dietary changes can greatly boost absorption.

The gut microbiome is in poor condition. An imbalance of intestinal flora can impair nutrient absorption. Reduce your sugar intake and eat more probiotic-rich foods like yogurt, sauerkraut, and kefir to keep your microbiome healthy.
