Glowing skin, strong nails, and healthy hair aren't just about the right skincare routine—they start from within. One essential nutrient that plays a major role in all three? Biotin (vitamin B7). Known for supporting hair growth, improving nail strength, and boosting skin health, biotin is a daily must-have for your body. This guide breaks down why biotin matters, how to spot a deficiency, and the best food sources to help you glow from the inside out.
01What Is Biotin?

Biotin, also known as vitamin B7, is a water-soluble B-vitamin that plays a crucial role in converting food into energy. It's instrumental in metabolising carbohydrates, fats, and proteins, thereby supporting various bodily functions. Beyond its metabolic duties, biotin is renowned for promoting healthy hair, skin, and nails, making it a staple in many beauty regimens.
02The Beauty Benefits of Biotin
1. Hair Health

There are plenty of benefits of biotin for hair. It is often hailed as a miracle nutrient for hair, and for good reason. It supports keratin production, the primary protein that makes up hair, thus enhancing hair strength and resilience. While biotin deficiency is rare, ensuring adequate intake can help maintain healthy hair growth and prevent hair thinning. For instance, the LBP Curry Leaves, Biotin & Mandarin Shampoo combines the nourishing properties of curry leaves and mandarin with biotin to support hair strength and vitality. Regular use can enhance hair texture and promote a healthy scalp environment.
2. Skin Vitality

Biotin contributes to the maintenance of healthy skin by supporting the production of fatty acids that nourish the skin. A deficiency can lead to skin issues such as rashes and dryness, so maintaining sufficient biotin levels is key to a radiant complexion.
3. Nail Strength

Brittle nails can be a sign of biotin deficiency. Supplementing with biotin has been shown to improve nail thickness and reduce splitting, leading to stronger, healthier nails.
03Recognising Biotin Deficiency

Though uncommon, biotin deficiency can manifest through various symptoms:
-
Thinning hair or hair loss
-
Skin rashes, particularly around the eyes, nose, and mouth
-
Brittle nails
-
Fatigue or lethargy
-
Neurological symptoms such as depression or tingling in the limbs
If you experience these symptoms, it's advisable to consult a healthcare professional for proper assessment and guidance.
04Top Biotin-Rich Foods to Include in Your Diet

Incorporating biotin-rich foods into your meals is a natural way to support your beauty and health goals. Here are some excellent sources of biotin foods.
1. Egg Yolks
Egg yolks are a powerhouse of biotin. Ensure they are cooked to reduce the risk of avidin interference, a protein in raw egg whites that can hinder biotin absorption.
2. Nuts and Seeds
Almonds, walnuts, and sunflower seeds are not only rich in biotin but also provide healthy fats that support skin health.
3. Legumes
Peanuts, soybeans, and lentils are excellent plant-based sources of biotin, making them ideal for vegetarians and vegans.
4. Whole Grains
Whole grains like oats and barley contain biotin and are also high in fibre, promoting overall digestive health.
5. Dairy Products
Milk, cheese, and yoghurt provide moderate amounts of biotin along with calcium and protein.
6. Avocados
This creamy fruit, currently enjoying its time in the food spotlight, is not only delicious but also a good source of biotin and healthy fats.
7. Sweet Potatoes
Sweet potatoes offer a healthy dose of biotin and are also rich in beta-carotene, which supports skin health.
8. Mushrooms
Certain varieties, like button mushrooms, contain biotin and can be a tasty addition to various dishes.
9. Bananas
While not the highest in biotin, bananas provide a small amount and are a convenient snack option.

06Tips for Biotin Absorption from Food

- Eat a balanced diet: Combine biotin-rich foods with other nutrients (like protein, healthy fats, and complex carbs) to support optimal absorption and overall health.
- Avoid raw egg whites: Raw egg whites contain avidin, a protein that binds to biotin and prevents its absorption. Always cook your eggs.
- Include probiotic foods: A healthy gut helps with nutrient absorption. Foods like yogurt, kefir, kimchi, and sauerkraut support gut health.
- Limit alcohol: Excessive alcohol can interfere with biotin absorption and reduce levels in the body.
- Stay hydrated: Water helps transport nutrients—including biotin—throughout the body.
- Minimize highly processed foods: These often lack essential nutrients and may disrupt gut function, affecting vitamin absorption.
- Consider cooking methods: Light steaming or sautéing biotin-rich vegetables like spinach and mushrooms can help retain more nutrients compared to overcooking.
