Known as the beauty vitamin, Vitamin B7, also called Biotin, is essential for healthy skin, hair, and nails — but its benefits go far beyond appearance.
It supports energy metabolism, nerve health, and the proper function of enzymes that turn food into fuel.
🌸 What Is Vitamin B7 (Biotin)?
Biotin is a water-soluble B-complex vitamin that helps your body convert carbohydrates, fats, and proteins into energy.
It also supports cell growth and gene regulation, making it vital for overall health.
Because the body doesn’t store Biotin, it must be replenished daily through food or supplements.
🍽️ Foods Rich in Vitamin B7 (Biotin)
Vitamin B7 is found in both animal and plant foods. A varied diet usually provides enough for most people.
🥚 Animal-Based Sources
- Eggs (especially yolks — but cook them, as raw egg whites block Biotin absorption)
- Liver and other organ meats
- Salmon, tuna, and sardines
- Pork and beef
- Milk, cheese, and yogurt
🌿 Plant-Based Sources
- Nuts (almonds, peanuts, walnuts)
- Seeds (sunflower, chia, flax)
- Whole grains (oats, barley, wheat germ)
- Legumes (soybeans, lentils, peas)
- Avocado and sweet potatoes
- Mushrooms and spinach
- Bananas and raspberries
💡 Tip: Pair Biotin-rich foods with a balanced intake of other B vitamins — they work together to support metabolism and energy.

Deficiency can result from:
- Eating raw egg whites often
- Gut disorders (affecting absorption)
