Biotin

A newly designated B Vitamin, it was discovered by the deficiency symptoms created through consuming large amounts of RAW EGGS. Avidin which is a protein and carbohydrate molecule in the egg white, binds with biotin in the stomach, decreasing its absorption. 
Biotin functions:

• Aids in cell growth

• Aids in fatty acid production
• Metabolism of carbs, fats, proteins and utilization of other B vitamins
• Healthy hair and skin (100 mg daily prevent hair loss in men)
• Promotes healthy sweat glands, nerve tissues and bone marrow as well as relieves muscle pain
• Deficiencies symptoms:
• Anemia
• Depression
• Hair loss
• High blood sugars
• Inflammation
• Pallor of the skin (unhealthy pale appearance)
• Mucus membranes
• Insomnia
• Loss of appetite
• Muscular pain
• Nausea
• Soreness of the tongue

Sources:

• Egg yolks
• Meat
• Milk
• Poultry
• Salt water fish
• Soybeans (non GMO)
• Whole grains

Raw egg whites contain a protein called avidin that combines with biotin in the intestines and depletes the body of this needed nutrients.  Fats and oils that are hydrogenated (exposed to high heats that damage the oil) or exposed to air, inhibit biotin absorption.
Antibiotics, sulfa drugs and saccharin also threaten the availability of Biotin
