Biotin plays a very important role in metabolism and works as a co-enzyme to help break down food, including carbohydrates, fats and protein which can be turned into energy. This reaction is further accelerated when biotin is paired with chromium picolinate. Your resting metabolic rate is elevated and food breaks down even faster when consuming biotin. There have been numerous studies that state Biotin can and cannot help you lose or gain weight and that it depends on the person. Natural benefits of biotin for weight loss can be achieved just be consuming a well-balanced diet but for those who still want to take biotin supplements for weight loss, at least 300mcg of biotin should be taken daily. This however, should not be a replacement for poor eating habits.
