“Regarding growth issues. Males may need much more zinc to grow to their full potential. Eating zinc-rich foods like liver might not be enough. First there is type-II zinc deficiencies, which can be caused by something as insidious as delayed hypersensitivities to foods, or spores or mycotoxins in the air breathed while sleeping. Second, males who discover the joys of masturbation can lose zinc in ejaculate. Another observation by a colleague was that “catch-up growth” frequently occurred when a zinc insufficiency was corrected. One boy grew six inches in less than a year. So maybe a trial of zinc for a month would be worth it? Maybe medical monitoring of copper status during the month for optimizing safety?”
