Biotin is a vitamin of the B complex that is found in egg yolk, liver, and yeast . It is also known as vitamin B7 or vitamin H . Biotin is involved in a wide range of metabolic processes, both in humans and in other organisms, primarily related to the utilization of fats, carbohydrates, and amino acids . It is a coenzyme for five carboxylase enzymes, which are involved in the catabolism of amino acids and fatty acids, synthesis of fatty acids, and gluconeogenesis . Biotinylation of histone proteins in nuclear chromatin plays a role in chromatin stability and gene expression.
Uses of biotin:
Protein purification: Biotinylated tags can be attached to proteins of interest. The biotin-streptavidin interaction is highly specific and strong, allowing for efficient purification of biotinylated proteins from complex mixtures.
Cellular and subcellular localization: Biotin tags can be attached to proteins to study their distribution and localization within cells or tissues using microscopy techniques.
Protein-protein interactions: Biotinylated tags can be used to study protein-protein interactions by pulling down biotinylated proteins and their interacting partners using streptavidin beads.
Nucleic acid labeling: Biotin can be incorporated into DNA or RNA molecules to study their structure, interactions, and expression patterns.
Immunoassays: Biotinylated antibodies can be used in immunoassays like enzyme-linked immunosorbent assays (ELISAs) to detect and quantify specific molecules.
Biotinylation of cell surfaces: Biotin can be added to cell surfaces to label and isolate specific cell populations.
Side effects
Allergic Reactions: In rare cases, individuals may develop allergic reactions to biotin supplements, resulting in symptoms like itching, hives, swelling, and difficulty breathing. If you experience any of these symptoms, discontinue use and seek medical attention immediately.
Acne and Skin Issues: Some people have reported experiencing acne breakouts or skin issues after taking high doses of biotin supplements. While biotin is often marketed for promoting healthy skin, taking excessive amounts might disrupt the balance of other nutrients and lead to skin problems.
Digestive Upset: Taking large doses of biotin supplements can cause digestive upset, including nausea, cramping, and diarrhea. It’s important to follow the recommended dosage guidelines to avoid these issues.
Interference with Lab Tests: Biotin can interfere with certain lab tests, such as those measuring hormone levels or thyroid function. High doses of biotin in the bloodstream can lead to inaccurate test results, potentially causing misdiagnoses or inappropriate treatments.
Drug Interactions: Biotin supplements might interact with certain medications. For example, anticonvulsant medications used to treat seizures might lower biotin levels in the body. If you’re taking any medications, consult your healthcare provider before adding biotin supplements to your regimen.
Causes of biotin deficiency
Inadequate Diet: Not eating enough foods rich in biotin, like eggs, nuts, and fish, can lead to a deficiency. Biotin is in these foods, and if you don’t consume them regularly, you might not get enough.
Certain Health Conditions: Some medical conditions can make it hard for your body to absorb biotin from the food you eat. These conditions might include certain digestive disorders that affect nutrient absorption.
Medications: Certain medications, like antibiotics, can interfere with the production of biotin in your gut, which could lead to lower levels in your body.
Genetic Factors: Some people are born with genetic conditions that make it difficult for their bodies to process or use biotin properly, leading to a deficiency.
Pregnancy and Breastfeeding: During pregnancy and breastfeeding, a woman’s body might need more biotin than usual, and if she doesn’t get enough through her diet or supplements, a deficiency could occur.
Food sources
Eggs: Egg yolks are a rich source of biotin. However, consuming large amounts of raw egg whites over a prolonged period can inhibit biotin absorption due to the presence of avidin.
Nuts and Seeds: Almonds, peanuts, walnuts, and sunflower seeds are good sources of biotin.
Fish: Salmon, tuna, and mackerel contain biotin, along with providing heart-healthy omega-3 fatty acids.
Meat: Organ meats like liver and kidneys are high in biotin, as are other types of meat like beef and pork.
Dairy Products: Cheese, milk, and yogurt contain moderate amounts of biotin.
Legumes: Beans, lentils, and soybeans contribute to biotin intake.
Whole Grains: Whole wheat bread, oats, and brown rice are sources of biotin.
Fruits and Vegetables: Some fruits and vegetables contain smaller amounts of biotin. Examples include avocados, bananas, cauliflower, mushrooms, and sweet potatoes.
Vegetables: Spinach and broccoli are biotin-rich veggies that can be added to your meals.
Yeast and Yeast Extracts: Nutritional yeast and yeast extracts are often used as seasoning and are a source of biotin, especially in vegan diets.
Fortified Foods: Certain foods, such as breakfast cereals, might be fortified with biotin to enhance their nutritional content.

Natural remedies
Balanced Diet: A nutritious diet rich in protein, vitamins (especially B-vitamins like biotin), minerals (like zinc and iron), and omega-3 fatty acids can provide the essential nutrients your hair needs for growth.
Scalp Massage: Gently massaging your scalp increases blood circulation, which can stimulate hair follicles and promote growth. You can use your fingertips or a soft brush for this.
Aloe Vera: Aloe vera gel contains enzymes that can help promote healthy hair growth. Apply aloe vera gel directly to your scalp, leave it for about 30 minutes, and then rinse.
Coconut Oil: Massaging your scalp with warm coconut oil can help moisturize the scalp and strengthen hair. Leave it on for a few hours or overnight before washing.
Onion Juice: Onion juice contains sulfur, which can improve blood circulation and promote hair growth. Apply onion juice to your scalp and leave it for 15-30 minutes before rinsing.
Egg Mask: Eggs are rich in protein and biotin, both of which are important for hair health. Mix an egg with olive oil and apply it to your hair for about 20-30 minutes before washing.
Green Tea: Green tea contains antioxidants that can help promote hair growth. You can apply brewed and cooled green tea to your scalp or use green tea-infused products.
Rosemary Oil: Rosemary oil is believed to increase circulation and promote hair growth. Mix a few drops of rosemary oil with a carrier oil (like coconut or jojoba) and massage it into your scalp.
Castor Oil: Castor oil is thought to promote hair growth due to its ricinoleic acid content. Massage it into your scalp and leave it overnight before washing.
Healthy Hair Habits: Avoid excessive heat styling, tight hairstyles, and harsh chemical treatments that can damage hair. Use a gentle shampoo and conditioner suitable for your hair type.
Stay Hydrated: Drinking enough water is crucial for overall hair health, as dehydration can lead to dry and brittle hair.
Manage Stress: Chronic stress can contribute to hair loss. Practicing stress-reduction techniques like yoga, meditation, or deep breathing can help.
