B12 is essential for nerve health. Low levels can damage the nerves, causing a tingling or "pins and needles" sensation in the hands and feet. This may progress into severe nerve dysfunction if left untreated.

B12 is vital for red blood cell production. Low levels can lead to anemia, causing an irregular heartbeat, breathlessness, dizziness, or even heart palpitations due to reduced oxygen flow.

Feeling tired all the time? A B12 deficiency reduces red blood cell production, limiting oxygen supply to your body. This leads to persistent fatigue, muscle weakness, and low energy, even with proper rest.

A lack of B12 can cause anemia, making your skin appear pale or yellowish. Without enough healthy red blood cells, oxygen delivery is compromised, leading to dull and lifeless skin.
