Interesting Fact

Biotin: The B Vitamin Secretly Found in Eggs and Nuts

Biotin, also known as vitamin B7, is a vital nutrient your body uses to help convert food into energy. It naturally occurs in everyday foods like eggs, nuts, and whole grains. Since it's water-soluble and not stored in large amounts, getting enough biotin from your diet—or a supplement—helps support the body’s ongoing metabolism of carbohydrates, fats, and proteins every day.

Frequently Asked Questions About Biotin

What are common natural food sources of biotin?
