Food Zinc Complex is an excellent 100% Food source of organic zinc. Most researchers acknowledge that organic zinc is better absorbed than inorganic zinc . Zinc itself is generally found in the human body attached to a peptide [1,2]; it is often attached with albumin [1,2] or alpha2-macroglobulin  or exists as part of one of the many zinc metalloenzymes [1,2]. Zinc, as found Food Zinc Complex, is in a complex matrix of peptides, carbohydrates and lipids. Zinc is not naturally found in the body as zinc citrate, zinc chloride, zinc picolinate, etc. Zinc deficiency in humans can cause alopecia, impotence, skin problems, immune deficiencies, increased susceptibility to infection/sore throats, night blindness, impaired taste, delayed wound healing, impaired appetite, photophobia (hypersensitivity to light), difficulty in dark adaptation, growth retardation, male infertility (low sperm counts), liver enlargement, and spleen enlargement [1,2].
Nutritional yeast is an excellent source of zinc because, “fermenting organisms produce phytases that break down phytate and increase the amount of absorbable zinc” . Nutritional yeast also contains certain amino acids  that enhance the absorption of zinc . Since diabetics seem to need zinc, but there deficiencies are refractory to zinc salts , food forms of zinc should also be a better choice for absorption for this population.
