What is Biotin and Why Do We Need It?
Biotin, also known as vitamin B7, is a water-soluble B-vitamin that plays a crucial role in converting food into energy. It acts as a coenzyme for several enzymes involved in the metabolism of carbohydrates, fats, and amino acids. While biotin deficiency is rare, maintaining adequate intake is important for overall health, supporting functions related to the nervous system, liver, eyes, hair, and skin. For those following a plant-based diet, legumes represent a fantastic source of biotin alongside other vital nutrients like protein and fiber.
The Legume Powerhouses: Top Sources of Biotin
Not all legumes are created equal when it comes to biotin content. Certain types are far more concentrated in this vitamin than others. Here we break down some of the best legume sources to add to your meals.
Soybeans: The Richest Legume Source
Soybeans stand out as the most concentrated legume source of biotin. A 100-gram serving of whole soybeans can provide a remarkable 19.3 mcg of biotin, covering 64% of the Daily Value. This makes them a staple for anyone looking to boost their intake. Soybeans can be enjoyed in various forms:
- Edamame: Steamed and lightly salted edamame is a simple, healthy snack.
- Tofu: This versatile soy product can be scrambled, stir-fried, or baked.
- Tempeh: Fermented soybeans offer a unique texture and flavor, adding biotin to any dish.
- Soy Milk: A convenient way to consume soybeans, soy milk is great in smoothies, cereals, or used in baking.
Peanuts: A Widely Available Option
While botanically a legume, peanuts are often categorized with nuts. They are a rich and accessible source of biotin. A small 1-ounce (28-gram) serving of roasted peanuts provides nearly 5 mcg of biotin, which is 17% of the DV. Peanuts offer several easy ways to incorporate biotin into your diet:
- As a snack: Roasted peanuts are a classic and convenient snack.
- Peanut butter: A spoonful of peanut butter can be a delicious addition to breakfast or snacks.
- In dishes: Peanuts are a common ingredient in many savory dishes, such as stir-fries and curries.
Lentils and Peas: Excellent Everyday Choices
Lentils and peas are highly nutritious and contribute a good amount of biotin to a balanced diet.
- Lentils: Different varieties of lentils provide biotin. Cooked lentils can be used as a base for hearty curries like dal, salads, and soups.
- Green Peas: Fresh or frozen green peas are a versatile vegetable that can be added to pasta, stir-fries, and side dishes.

The Holistic Health Benefits of Legumes
Beyond biotin, incorporating legumes into your diet provides a range of benefits. They are excellent sources of plant-based protein, which is vital for tissue repair and muscle maintenance. Their high fiber content supports digestive health and can help manage weight and cholesterol levels. Additionally, legumes provide other essential nutrients like iron, magnesium, and potassium. Choosing whole foods like legumes ensures you get a complete nutritional package, rather than relying solely on supplements.
Biotin and Plant-Based Diets
Vegetarians and vegans can easily meet their biotin requirements by focusing on a varied diet rich in legumes, nuts, seeds, and certain vegetables. Combining various plant-based sources throughout the day is a reliable strategy. The biotin from these whole food sources is effectively absorbed by the body, ensuring you receive its full range of benefits.
