Biotin supplementation is sometimes recommended for individuals with specific health conditions, but it’s essential to consult with a healthcare professional before starting any supplementation.

Brief History of Vitamin B7, a.k.a Biotin

The discovery and understanding of Vitamin B7, also known as biotin, are relatively more recent compared to some other vitamins. The story of biotin began in the early 20th century when scientists observed that feeding animals raw egg whites led to symptoms of skin disorders and hair loss. Researchers initially identified a substance in egg whites that caused these effects and called it “egg-white injury factor.”

In the 1930s, scientists isolated the substance responsible for preventing this condition. They named it biotin, derived from the Greek word “biotos,” meaning life. The vitamin was recognized as a member of the B-vitamin complex, and its chemical structure was elucidated in subsequent years.

Biotin’s essential role in various metabolic processes, particularly in the metabolism of fats, carbohydrates, and proteins, became apparent. Over time, biotin’s importance in maintaining healthy skin, hair, and nails was also recognized.

Today, biotin is well-established as a vital nutrient, and its deficiency is rare. It is widely available in various foods, and supplements are sometimes recommended for specific health conditions.

Deficiency of Vitamin B7, a.k.a Biotin

Vitamin B7 deficiency, also known as biotin deficiency, is relatively rare because biotin is widely available in a variety of foods and is also synthesized by gut bacteria. However, certain factors can contribute to a deficiency, leading to a range of symptoms. Here are some causes and potential symptoms of Vitamin B7 deficiency:

Causes:

1. Poor Diet:
   • Inadequate intake of foods containing biotin, especially in individuals with highly restrictive diets.
2. Raw Egg White Consumption:
   • Consuming large amounts of raw egg whites over an extended period can lead to biotin deficiency. Raw egg whites contain avidin, a protein that binds biotin and reduces its absorption.
3. Gastrointestinal Disorders:
   • Conditions that affect nutrient absorption in the gastrointestinal tract, such as inflammatory bowel diseases or certain surgical procedures.
4. Genetic Factors:
   • Rare genetic conditions that affect biotin metabolism.

Symptoms:

1. Hair Loss:
   • Biotin deficiency may lead to hair thinning or loss.
2. Skin Issues:
   • Dermatitis, characterized by dry and scaly skin, is a common symptom.
3. Brittle Nails:
   • Biotin is associated with maintaining healthy nails, and a deficiency may lead to brittle or easily breakable nails.
4. Neurological Symptoms:
   • In severe cases, neurological symptoms such as depression, lethargy, hallucinations, and numbness or tingling in the extremities may occur.
5. Conjunctivitis:
   • Inflammation of the conjunctiva, the thin membrane covering the white part of the eye.
6. Developmental Issues in Infants:
   • Biotin deficiency during pregnancy or breastfeeding can lead to developmental issues in infants.

Treatment for biotin deficiency typically involves increasing dietary intake through a well-balanced diet or using biotin supplements. Biotin supplementation is often effective in addressing symptoms associated with deficiency.
