Biotin is a B vitamin that helps your body convert food into energy.
Biotin is a water-soluble vitamin, which means that your body doesn’t store it. As a result, you need to consume it regularly to maintain adequate levels (
Biotin deficiency is so rare that there isn’t enough evidence to establish a Recommended Daily Allowance (RDA) or Estimated Average Requirement (EAR) for it. However, the Daily Value (DV) for biotin is typically around 30 mcg per day (
While biotin is available as a supplement, most people can get all they need by eating a varied diet.
Here are the top 10 biotin-rich foods.
A whole, cooked egg (50 grams) provides approximately 10 mcg of biotin, or approximately 33% of the DV (
You should always cook eggs fully, both to reduce your risk of Salmonella poisoning and improve biotin absorption. Egg whites contain a protein called avidin, which can interfere with biotin absorption if eaten raw (
Eggs can be hard-boiled, scrambled, or used to make baked goods like muffins or waffles.
Cooked whole eggs are a good source of biotin due to the yolk, which is rich in several B vitamins.
A 1-ounce (28-gram) serving of roasted peanuts contains just under 5 mcg of biotin, or 17% of the DV (
Legumes are typically boiled and used as a base for entrées and salads or incorporated into stir-fries or baked dishes.
Legumes, especially peanuts and soybeans, are a good source of biotin. They’re also high in protein, fiber, and other vitamins and minerals.
Nuts and seeds are a good source of fiber, unsaturated fat, and protein. Most also provide biotin, but the amount tends to vary by type (
Nuts and seeds can be enjoyed raw, tossed into salads, mixed into pasta dishes and stir-fries, or blended into homemade nut and seed butters.
Eating a variety of nuts and seeds is a good way to raise your biotin intake. Sunflower seeds and almonds are especially good sources.
Certain organ meats, especially liver, are high in biotin. This makes sense biologically, as most of your body’s biotin is stored in your liver.
Just 3 ounces (75 grams) of cooked beef liver provides nearly 31 mcg of biotin, or 103% of the DV (
Cooked chicken liver is an even richer source, packing 138 mcg per 3-ounce (75-gram) serving — a whopping 460% of the DV (
Some people enjoy liver fried with onions, minced into homemade burger patties, or chopped and cooked to top pasta dishes.
While liver isn’t one of the most popular foods, it’s one of the best sources of biotin. A standard serving of chicken and beef liver each provide over 100% of the DV.
Sweet potatoes can be baked or microwaved until soft. You can also peel, boil, and mash them or add them to homemade veggie burger patties.
Sweet potatoes are a great vegetable source of biotin, with 1/2 cup (125 grams), cooked, meeting 8% of the DV.
A 1-cup (70-gram) serving of chopped, fresh button mushrooms boasts 5.6 mcg, or 19% of the DV (
Canned mushrooms work well over noodles, atop homemade pizzas, and in sauces and gravies, while fresh mushrooms can also be stuffed and baked, sautéed, or added to salads.
Canned and fresh mushrooms are a good source of biotin and easy to add to numerous dishes.
They’re most often eaten on their own, but you can also add them to smoothies, spread nut butter on them, or freeze them to make nondairy ice cream.
Bananas are a sweet, nutritious, and popular snack, and they also provide small amounts of biotin.
You can enjoy it raw with hummus or dip, steamed, roasted with olive oil and seasoning, blended into soups, or sautéed and added to pastas and casseroles.
Broccoli provides small amounts of biotin and is rich in several other nutrients, including calcium and vitamins A and C.
Both nutritional yeast and brewer’s yeast provide biotin, but specific amounts vary by brand.
Brewer’s yeast, also called dry active yeast, is used to brew beer and leaven bread. Conversely, nutritional yeast is an inactive yeast that’s often used to make nondairy cheese.
Nutritional yeast may contain up to 21 mcg of biotin, or 69% of the DV, per 2 tablespoons (16 grams) (16).
Nutritional and active dry yeast, which are used as a food flavoring and in baking, respectively, are both good sources of biotin.
Avocados are best known as a good source of folate and unsaturated fats, but they’re also rich in biotin (
Avocados can be eaten raw, mashed onto toast, stirred into guacamole, and sliced to top salads, taco soup, and burritos.
Avocados, which are commonly used to make guacamole, are particularly rich in healthy fats, as well as biotin.
Biotin is a water-soluble B vitamin that your body needs to obtain from food. Deficiency is rare and can be avoided by eating biotin-rich foods.
Some of the best sources of biotin include legumes, egg yolks, organ meats, nuts, seeds, mushrooms, avocados, sweet potatoes, and yeast.
Biotin supplements are available as well, but most people can get all of the biotin they need by eating a balanced diet.
