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

EFSA 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
