This comprehensive multiple vitamin/ mineral supplement contains 23 highly bioavailable essential nutrients in amounts and ratios designed to address nutritional imbalances commonly observed in children on the spectrum. Gastrointestinal function, including transit time and absorption issues, affects a significant percentage of individuals on the spectrum and contributes to altered nutritional requirements. Food elimination diets and a tendency to be highly selective eaters further narrow dietary sources of essential nutrients. VitaSpectrum® addresses these inadequacies by supplying balanced amounts of vitamins, minerals, and trace elements in forms that are typically well tolerated by those on the spectrum. Bioactive forms of folate, B12, and B6 are included along with naturally sourced carotenes, vitamin E, and D for optimal nutrient absorption and utilization. Iron and copper, often contraindicated in those on the spectrum, are excluded. VitaSpectrum® is free of common allergens, including milk/casein, eggs, fish, shellfish, tree nuts, peanuts, and wheat/ gluten. No starch, maltodextrin, stearates, artificial sweeteners, colors, flavors, or preservatives are used. VitaSpectrum® formulas comply with Gluten-Free/Casein-Free (GFCF) diets. For maximum tolerance and versatility as a foundational nutritional program, herbal ingredients are avoided. The pleasant, natural berry-pomegranate, citrus and tropical flavored powder formulas dissolve easily in liquids or can be mixed in foods. A convenient measuring scoop is provided for accurate measurement.
