Any healthy natural supplements to grow taller, without proper Ryzex Male Enhancement doctor acknowledgement and authority approbation sounds really fishy to me. Athletes and other physically active people need about the same amount of nutrients as others do to grow taller just more energy, or calories, for the increased demands of exercise.The extra amount of food that active people eat supplies the very small amount of extra needed to grow taller and have more energy production, too. Although protein needs are somewhat higher for some athletes, especially for those in strength training sports, food can easily provide the extra. On another note, physical activity, not extra amino acids (protein), builds muscle. For more on nutrition for athletes and ergogenic aids.
