Biotin helps your body convert food into energy while supporting healthy hair, skin, and nails. Getting enough through diet can strengthen hair follicles and reduce breakage.
This list covers 84 options across meat, fish, eggs, dairy, nuts, seeds, vegetables, fruits, and grains. All values are approximate. Unless stated otherwise, nutritional values are based on a cooked 1-cup (240ml) serving.

FAQs
Most adults need about 30 micrograms of biotin per day, though some people take up to 5,000 micrograms as a supplement for hair health. It's best to start with biotin-rich foods and consult a healthcare provider before taking high-dose supplements, as excessive amounts aren't necessarily more effective.
Egg yolks, organ meats (especially liver), nuts like almonds and peanuts, and seeds such as sunflower seeds contain the highest biotin levels. Other excellent sources include salmon, sweet potatoes, spinach, and broccoli.
Most people notice improvements in hair strength and growth after 3-6 months of consistently consuming biotin-rich foods. Hair grows slowly, so patience is essential—biotin supports the growth process but won't produce overnight results.
Biotin is relatively heat-stable, so cooking doesn't significantly reduce biotin content in most foods. However, raw egg whites contain avidin, a protein that binds biotin and prevents absorption, so cooking eggs actually improves biotin availability.
Biotin foods can help reduce hair loss caused by biotin deficiency, which is rare but does occur. For hair loss from other causes like genetics, hormones, or medical conditions, biotin alone likely won't solve the problem, and medical advice should be sought.
Biotin from food sources is generally very safe since it's water-soluble and excess amounts are excreted through urine. Unlike high-dose supplements, eating biotin-rich foods won't typically cause side effects or interfere with lab test results.
Yes, plant-based eaters can easily meet biotin needs through nuts, seeds, sweet potatoes, mushrooms, avocados, and nutritional yeast. A varied plant-based diet typically provides adequate biotin without requiring supplements.
For most people with a balanced diet, biotin-rich foods provide sufficient amounts for healthy hair growth without supplements. Supplements are mainly beneficial for those with diagnosed deficiencies, certain medical conditions, or dietary restrictions that limit biotin intake.
