12 Best Biotin-Rich Foods and Their Health Benefits
Discover the top 12 biotin-rich foods and how they benefit hair, skin, nails, and overall health.
Biotin, also known as vitamin B7 or vitamin H, is a crucial water-soluble B vitamin that helps your body convert food into energy. It plays a vital role in supporting healthy hair, skin, nails, and metabolic function. While a biotin deficiency is rare, including adequate biotin-rich foods in your diet can help maintain optimal health and vitality. This comprehensive guide highlights 12 foods packed with biotin, their health benefits, serving suggestions, and answers to common questions about this essential nutrient.
What Is Biotin and Why Do You Need It?
Biotin is an essential vitamin your body needs but cannot store, making it important to consume regularly through your diet. Biotin acts as a coenzyme for several metabolic processes, including fatty acid synthesis, glucose metabolism, and amino acid breakdown. This means biotin helps:
- Convert carbohydrates, fats, and proteins into usable energy
- Support strong hair, vibrant skin, and resilient nails
- Promote healthy brain, liver, and nervous system function
- Assist in cell growth and gene regulation
The suggested Daily Value (DV) for biotin in adults is 30 micrograms (mcg). Although most people get enough biotin from a well-balanced diet, certain groups—such as pregnant or breastfeeding women—may require more.

Signs of Biotin Deficiency
- Thinning hair or hair loss
- Skin rashes or irritation (especially around the mouth, nose, or eyes)
- Brittle nails
