Manganese ascorbate, manganese aspartate, manganese bisglycinate and manganese pidolate as sources of manganese added for nutritional purposes to food supplements [PDF]

open access: yesEFSA Journal, 2009
No specific studies on bioavailability were made available on any of the manganese sources considered in this opinion. However it can be assumed that manganese sources will dissociate in the stomach and/or in the gastrointestinal fluids into their constituents and that bioavailability in the gastrointestinal tract would be at least similar to that from

State of Manganese in Manganese Oxides [PDF]

open access: yesNature, 1949
CHEMICAL estimation of trivalent manganese has been possible using a stable complex ion formed with acetylacetone. This complex is formed from solutions of red manganic sulphate and also when γ-Mn2O3 is dissolved in concentrated hydrochloric acid in the presence of acetylacetone.
