Did you know that peanuts deliver more than just protein and healthy fats? One nutrient that hides in plain sight is biotin—a B vitamin (also known as vitamin B7) with some underrated perks. Biotin plays a crucial role in supporting your body’s metabolism, helping you convert food into usable energy. But the surprises don’t stop there.
Biotin is famous in beauty circles for its link to strong hair and nails, but it’s just as important for nervous system function and cell growth. A 100g serving of roasted peanuts can provide up to 60% of your daily biotin needs—making them one of the richest natural sources around (source: NIH Office of Dietary Supplements).
If you’re skipping peanuts because of their fat content, remember: these are mostly healthy monounsaturated fats, and the real-world portion for biotin is just a small handful. Unlike many supplements, biotin from whole foods like peanuts is particularly well-absorbed by the body. Next time you're craving a crunchy snack, swap out the chips for peanuts—not just for the crunch, but for a small but mighty biotin top-up your body (and your hair) will appreciate.
