A widely followed online doctor has sparked discussion after linking a common physical trait to a possible health issue. The claim suggests that what looks like a minor cosmetic change could point to something deeper in the body.
According to the Daily Express, Dr Eric Berg, who has millions of followers on TikTok, highlighted pale skin as a potential warning sign of low vitamin B12 levels in a viral video.
In the clip, he stated: “Pale skin, B12 deficiency.”
Why it matters
Vitamin B12, also known as cobalamin, is essential for producing red blood cells and keeping the nervous system functioning properly.
The NHS explains that the vitamin also plays a key role in DNA production and nerve health.
When levels drop too low, people can develop vitamin B12 deficiency anaemia, a condition that reduces healthy red blood cells and may cause the skin to look pale or slightly yellow.
The National Institutes of Health notes that reduced red blood cell production can limit oxygen flow in the body, contributing to fatigue and a washed-out appearance.
Signs to watch
The British Dietetic Association says B12 is naturally found in foods such as meat, fish, eggs and dairy products.
Some cereals and plant-based milks are fortified with the vitamin, which is particularly important for vegetarians and vegans who may struggle to get enough through diet alone.
Research cited by Cleveland Clinic links low B12 levels to symptoms including tingling in the hands and feet, memory problems and difficulty with balance.
The NHS adds that severe tiredness, breathlessness, headaches, mouth ulcers and vision changes can also occur.
When to check
Experts stress that pale skin can have multiple causes, including anaemia, low blood pressure or infections, according to Mayo Clinic.
However, ongoing paleness combined with weakness or fatigue may indicate an underlying deficiency.
Health guidance advises speaking to a GP if symptoms persist, as a simple blood test can confirm vitamin B12 levels and guide treatment.
