Common Signs and Symptoms of Biotin Deficiency

Common Signs and Symptoms of Biotin Deficiency

Biotin (vitamin H) is a micronutrient that is essential for beautiful hair, healthy skin and strong nails. The only problem is not everyone gets enough biotin from their daily diet. Starting to think you might need to re-up on biotin because your nails are brittle and frail, your hair is prone to breakage and your skin could use a boost? Here is a brief look at some of the other telltale signs and symptoms associated with biotin deficiency.


Besides brittle hair, a dull complexion and weak nails, many experts have concluded that one of the most prevalent signs among those who are lacking biotin is itchy skin around the mouth.

Muscle Pain

Muscle fatigue is yet another sign of biotin deficiency. Biotin helps repair muscle tissue, which is why those who get enough of it are less likely to suffer from everyday aches and muscle pains.

Dry Mouth

Another sign that you might be lacking biotin is a dry mouth. This is because salivary glands can't properly function unless they are provided with enough nourishing vitamins, such as biotin.


When it comes to the psychological side of things, a biotin deficiency can lead to mild depression or exacerbate anxiety. This is because it is essential for the balance of cognitive levels.


While a biotin deficiency can lead to depression and anxiety, it can also cause one to feel lethargic, frequently fatigued and unmotivated without explanation.


Some experts believe that biotin deficiency may even cause slight anorexia, a condition that has the potential to lead to heart failure and other serious complications.

Biotin deficiency is more common than you might think. If you feel you could be biotin deficient, try adjusting your diet to include more biotin-rich foods and find yourself a brand of biotin supplements you can rely on.
