Egg yolks are one of the most concentrated sources of biotin. One cooked egg provides about 10 mcg of biotin, which is approximately 33% of the recommended daily intake.
- Benefits: Eggs are also high in protein, healthy fats, vitamin D, and choline. These nutrients work together to support skin repair, muscle building, and brain health.
- How to Enjoy: Boiled, scrambled, poached, or as part of a veggie-packed omelet.
Note: Always cook eggs to avoid the risk of avidin (a protein in raw egg whites) binding to biotin and preventing its absorption.
Almonds
Almonds are not just great for snacking; they’re also a strong source of biotin. A quarter cup of almonds contains around 1.5 mcg of biotin.
- Benefits: Rich in vitamin E, magnesium, and fiber, almonds promote heart health and help stabilize blood sugar levels.
- How to Enjoy: Eat them raw, roasted, or added to smoothies, oatmeal, or homemade energy bars.
Sweet Potatoes
Sweet potatoes provide about 2.4 mcg of biotin per 1/2 cup cooked.
- Benefits: High in beta-carotene, which the body converts into vitamin A, sweet potatoes also support eye health and immune function.
- How to Enjoy: Baked as fries, mashed with herbs, or added to soups and casseroles.
Sunflower Seeds
Sunflower seeds offer approximately 2.6 mcg of biotin per 1/4 cup.
- Benefits: They are loaded with vitamin E, selenium, and healthy fats, which combat inflammation and oxidative stress.

Liver (Beef or Chicken)
Organ meats like liver are among the richest sources of biotin. A 3-ounce serving of cooked beef liver contains about 30.8 mcg of biotin, exceeding the daily requirement.

Frequently Asked Question
Can you get enough biotin from food alone?
Yes. Most people can meet their biotin needs through a varied, nutrient-rich diet without supplementation.
What are the symptoms of too much biotin?
Biotin is water-soluble, so excess amounts are typically excreted. However, very high doses may interfere with lab tests, including thyroid and hormone panels.
Is biotin good for hair growth?
Biotin is commonly promoted for hair health. While deficiency can cause hair loss, supplementing beyond normal levels doesn’t always result in noticeable hair growth in healthy individuals.
Are there any side effects to biotin supplements?
Most people tolerate biotin supplements well, but large doses can cause skin rashes, digestive upset, or interact with medications.
Is biotin safe during pregnancy?
Yes, and it’s important. Pregnant women need slightly more biotin and should ensure they meet the RDA through diet or prenatal vitamins.
How can vegans get enough biotin?
Plant-based sources like nuts, seeds, sweet potatoes, avocados, and mushrooms are excellent options for vegans.
Can biotin help with brittle nails?
Yes. Several studies have shown that biotin supplementation may help improve nail strength and reduce brittleness in people with weak nails.
