Biotin, also known as vitamin H, is an important vitamin for the circulatory system. Its involvement in the bio-synthesis of many substances is essential for a healthy skin, digestive tract, and your cells. Fortunately, we have bacteria in our intestine that produces this vitamin, making deficiencies rare, as long as you eat a healthy diet. You can find it in good supply in whole grain products, wheat germ, beef liver, Brewer’s yeast, nuts, cauliflower, mushrooms and eggs. Other foods that contain it in a smaller supply are salmon, halibut, strawberries, and milk.

Researchers have studied the effect of biotin supplements in aiding type 2 diabetes with preliminary results indicating that a combination of biotin and chromium might improve blood sugar control.
