I am always hesistant advising parents to give their children pharmaceutical grade products that enhance size and muscles. L-glutamine may have its value as a supplment, but it would better to control balanced growth in the body through a balanced diet, exercise and exposure to sunlight. The body manufactures its amino acids and proteins from the carbon, oxygen, nitrogen and hydrogen molecules it takes from the enhaled air. Just like vegetable plants using the carbon and hydrogen molecules from the air to produce carbohydrates (the vegetables we eat), our body is capable of making most everything it needs to sustain itself, provided we get sunshine, water, some other nutrients and love, love being the most powerful growth inducer of all. About 80 percent of all orphans East block countries are autistic. They stopped growing properly when their parents put them in to orphanages because they could not afford them. In this sense, love and caring attention do much more than a smart supplement.
