Most common signs of vitamin B deficiency everyone should look out for

Vitamin B is an essential nutrient that is the backbone of many vital bodily functions, from energy production to maintaining a healthy nervous system. Despite its importance, many individuals unknowingly fall short of their daily vitamin B needs, which can lead to a range of health complications. Recognising the signs of a vitamin B deficiency is crucial for maintaining overall well-being.Here are some key indicators to watch for.

Fatigue and weakness

One of the most common signs of vitamin B deficiency is fatigue and weakness. If you often feel tired, even after getting enough sleep, it could be a sign that your body is not getting enough vitamin B. According to a study published in the Journal of Nutrition, vitamin B12 deficiency can lead to fatigue and weakness due to its role in energy production in the body.

Pale or jaundiced skin

Another noticeable sign of vitamin B deficiency is pale or jaundiced skin. Vitamin B12 deficiency, in particular, can cause a reduction in red blood cell production, leading to a condition known as megaloblastic anaemia. This can result in pale or yellowish skin, as well as weakness and shortness of breath. A study published in the American Journal of Hematology found that vitamin B12 deficiency was a common cause of megaloblastic anaemia.

Tingling or numbness

Tingling or numbness in the hands and feet can also be a sign of vitamin B deficiency. This is because vitamin B12 plays a crucial role in nerve function, and a deficiency can lead to nerve damage. According to research published in the Journal of Neurology, Neurosurgery & Psychiatry, vitamin B12 deficiency can cause peripheral neuropathy, resulting in tingling, numbness, and loss of sensation in the extremities.

Mouth ulcers or cracks in the corners of the mouth

If you frequently experience mouth ulcers or cracks in the corners of your mouth, it could be a sign of vitamin B deficiency. Deficiencies in vitamin B2 (riboflavin) and vitamin B3 (niacin) have been linked to these symptoms. A study published in the Journal of Clinical and Diagnostic Research found that vitamin B2 deficiency was associated with an increased risk of oral ulcers.

Mood changes or depression

Vitamin B deficiency has also been linked to mood changes and depression. Research published in Nutrients suggests that low levels of vitamin B6, vitamin B12, and folate may be associated with an increased risk of depression. These vitamins play a crucial role in the synthesis of neurotransmitters such as serotonin and dopamine, which regulate mood.
