Biotin (also known as Vitamin B7 or Vitamin H) injections can aid weight loss, by elevating your resting rate of metabolism. One of the biggest benefits of biotin is that it helps stimulate hair growth, causing hair to thicken and appear more lustrous. Biotin can also help strengthen brittle nails. Biotin is given as an intra-muscular injection, allowing the body to absorb the supplement more readily, for quicker results.
