Having an unusually pale complexion might signal more than just a superficial concern. According to one health authority, it could be your body’s way of alerting you to a deficiency in an essential nutrient.

Dr. Eric Berg, a prominent figure with 2.3 million followers and over 30 million likes on TikTok, recently spotlighted this issue in a trending video.

In the clip, he succinctly states, “Pale skin, B12 deficiency.” Vitamin B12, also known as cobalamin, plays a crucial role in the production of red blood cells and the maintenance of a healthy nervous system. The NHS notes that B12 is vital for DNA synthesis and the proper functioning of nerve cells.

A lack of this vitamin can lead to vitamin B12 deficiency anemia, a condition identified by the NHS as leading to a reduced count of healthy red blood cells, which might cause the skin to appear pale or even slightly yellowish.

Red blood cells are responsible for delivering oxygen across the body. When B12 levels are inadequate, as indicated by the National Institutes of Health, the body struggles to produce enough healthy cells, resulting in fatigue and a pallid skin tone.

Vitamin B12 is naturally found in various animal-derived foods. According to the British Dietetic Association, meat, fish, eggs, and dairy products are excellent sources of this vital nutrient.

Certain breakfast cereals and plant-based milks are also enriched with the nutrient. According to the NHS, this is especially significant for vegans and vegetarians, who may find it challenging to obtain adequate B12 through diet alone.

B12 plays a crucial role in maintaining a healthy nervous system. Research referenced by Cleveland Clinic indicates deficiency can result in symptoms such as tingling in the hands and feet, memory difficulties and balance problems.

Other frequent warning signs include severe fatigue, breathlessness and headaches. The NHS reports that individuals with B12 deficiency anaemia may also suffer from mouth ulcers or alterations in vision.

Pale skin itself can have multiple potential causes. According to Mayo Clinic, anaemia, low blood pressure, infections and diminished blood flow can all cause skin to appear paler than normal.

Nevertheless, persistent paleness accompanied by fatigue or weakness may suggest an underlying deficiency. Experts advise anyone concerned about symptoms should consult a GP, as a straightforward blood test can assess vitamin B12 levels and inform treatment.
