The longer answer is that vitamins, especially the B vitamins (thiamine, riboflavin, niacin, pantothenic acid, Vitamin B6, biotin, and folic acid) do contribute to energy metabolism, by helping your body turn carbohydrates, proteins, and fats into utilizable energy.
One of the best vitamins for weight loss is vitamin B. Vitamin B is a group of eleven vitamins that work together. Some of the B vitamins that aid in weight loss are B6 (pyridoxine), B5 (pantothenic acid), and B2 (riboflavin). Vitamin B6 helps the pancreas produce enzymes that aid in digestion. Proper digestion will make one feel full longer, thus resulting in weight loss.
