Weight gain in Teens: The dietary guidelines for america (http://www.Cnpp.Usda.Gov/dietaryguidelines.Htm) state the current calories that a teenshould take daily. Typical american diet provides enough protein for muscle building even during strength training. Consult a dietitian or your physician if you feel you are underweight and a plan can be created for stable weight gain. Do not take above supplements.
