9. Yeast
You can find a surprising amount of biotin in two different kinds of yeast: nutritional yeast and brewer’s yeast (specific amounts vary by brand).
Brewer’s yeast, aka active yeast, is used for brewing beer and making bread. A standard 2.25-teaspoon (7-gram) packet of active dry yeast used for baking provides 1/4 micrograms of biotin, or 5 percent of the DV.
Nutritional yeast is an inactive yeast that’s often used to make nondairy cheese (you can also eat it on its own). It may contain up to 21 micrograms of biotin for every 2 tablespoons (16 grams).
10. Avocados
Here’s one more reason to love avocados: they’re a great source of biotin.
A medium avocado (200 grams) contains at least 1.85 micrograms of biotin, or 6 percent of the DV. They are also a great source of folate and unsaturated fats.
