Vitamin B12 is essential for energy and brain health, and a deficiency can cause a wide range of symptoms. If you often feel tired, weak,

or sluggish despite proper rest, low B12 may be the cause. Tingling in the hands or feet can also occur, pointing to nerve issues tied to deficiency.

Other warning signs include pale or slightly yellow skin, caused by reduced red blood cell production. Some people experience memory lapses, poor

concentration, or mood changes like anxiety and depression, reflecting B12’s role in supporting brain function and regulating mood chemicals.

Physical symptoms may include shortness of breath, dizziness, or a swollen, smooth tongue. In severe or prolonged cases, vision

problems and muscle weakness may develop. These issues typically build gradually, making the condition easy to overlook without testing.

Those most at risk include older adults, vegans, and people with digestive conditions or on medications that limit absorption.

To maintain healthy levels, include foods like fish, eggs, dairy, and fortified cereals in your diet. Supplements may also help if recommended.

If you notice these symptoms, it’s best to consult a healthcare professional and check your B12 levels before they lead to lasting complications.
