6 Signs of Biotin Deficiency

Biotin is one of the B complex vitamins. This group of vitamins is responsible for breaking down fat and carbohydrates from the foods you eat and turning them into energy. This energy provides fuel for many of your body’s necessary functions. Biotin is also sometimes called B-7, vitamin H or coenzyme R.

Biotin promotes good skin health, and it helps regulate your LDL (bad) cholesterol and blood sugar. It is also necessary to produce keratin, a protein that promotes strong nails and hair.

Biotin is a water-soluble vitamin. That means it’s not stored in your body for long. Your body doesn’t naturally produce it, either. However, the bacteria in your gut can produce biotin. These bacteria, also called intestinal flora, have a healthy impact on your health.

Biotin deficiency can be cured if you can recognize these 6 signs of biotin deficiency:

1. Fine and Brittle Hair

Biotin is known to supplement hair strength and one sign that is visible that a person is deficient in biotin is having fine and brittle hair. Biotin helps promote healthy and strong hair and with lacking biotin, the hair starts to brittle or easily break when you try to brush or comb your hair. To avoid this, taking in biotin supplements can strengthen and make the hair healthy.

2. Skin Rash

The skin is usually the first to show when one is biotin deficient. Due to improper fat metabolism, one can develop acne, dry itchy skin, erythematous rash on the face and body.

3. Dermatitis

Skin inflammation is one of the common symptoms of biotin deficiency. The common form of dermatitis that is found in people who are suffering from biotin deficiency is seborrhoeic dermatitis. This disease causes flaking and itching on the scalp that may lead to balding. Children who are affected by this condition may suffer from muscle pain and hair problems. Symptoms such as thinning of hair, red-scaly skin and brittle nails are common signs of biotin deficiency. A proper supplement of biotin may reduce muscle cramps in kids.

4. Hair Loss And Thinning

Hair loss caused by biotin deficiency can be reversed. One of the most obvious symptoms of biotin deficiency is hair loss. This may progress from fine brittle hairs, thinning and eventually, hair loss, which can lead to alopecia also called baldness.

5. Oral Health Problems

Oral health reflects the relationship you have with consuming proper nutrients in your diet considering many of vitamins and minerals are responsible for protecting the oral cavity. Malnutrition can manifest in various ways in the oral cavity and develop into more severe health challenges down the road.

6. Muscular Cramps In Legs

Frequent muscle cramping in the calves, arches of the feet and a stabbing sensation in your toes may be a sign that you are deficient in one of the critical nutrients that work in balance to control other ions. You may just be working up a sweat more often than before which increases your loss of electrolytes. However, whether your cramps occur over short or long-term periods this symptom should be treated accordingly.


Biotin is an essential vitamin that affects not only the hair but the health of the body. Experiencing biotin deficiency is an urgent call to check on our health status. Taking in biotin supplements can help lift the signs of biotin deficiency. In this post, I shared with you 6 signs of biotin deficiency.Biotin Supplements
