Vitamin B12, also known as cobalamin, is crucial nutrient that plays a key role in many bodily functions, including the formation of red bl00d cells, nerve health, and DNA synthesis.
A lack of vitamin B12 can lead to a wide range of effects, some of which may be subtle at first but can become serious over time if left untreated. Below, we explore nine common effects of vitamin B12 deficiency and why it’s important to spot the signs early.
1. Fatigue and Weakness
One of the earliest and most popular effects of a B12 deficiency is feeling constantly sad or weak. This happens because your body can’t create enough healthy red bl00d cells without adequate B12.
2. Pale or Jaundiced Skin
If your skin looks unusually pale or has a slight yellow tint, it could be an effect because of a lack of vitamin B12. This condition happens when red bl00d cells break down more easily (a process called hemolysis), releasing bilirubin, which gives the skin a yellowish appearance.
3. Shortness of Breath and Dizziness
When your red blood cell count drops, your body struggles to get enough oxygen to your tissues, leading to shortness of breath—especially during physical activity. You might also experience dizziness or lightheadedness, particularly when standing up quickly.
