What is Manganese Sulphate (Manganese Sulphate · Food Supplement & Animal Feed)?
Manganese sulphate is a soluble, economical, and high-manganese-content inorganic salt of the trace element manganese. Manganese is a cofactor for enzymes necessary for energy metabolism, bone, connective tissue, and antioxidant defense (Mn-SOD). It is a manganese source whose bioavailability is referenced by EFSA FEEDAP.
- Molecular formula: MnSO₄
- CAS number: 7785-87-7
- Form: Powder
- Quality: Food / Pharmaceutical Grade
- Manganese(II) sulphate monohydrate (MnSO4·H2O) contains ~32.5% elemental manganese (anhydrous ~36.4%). Due to its high manganese content and low cost, it is a common inorganic source, especially in feed and fortification premixes.
What is Manganese Sulphate · Food Supplement & Animal Feed Used For? Why is it Used?
Manganese sulphate is an inorganic manganese source preferred for large-scale fortification and feed premixes due to its high elemental manganese content and low cost. It can be positioned with EFSA-approved functions for energy metabolism, bone, connective tissue, and protection against oxidative stress; however, total intake should be controlled due to its narrow safety margin.
Main areas of use: Dietary Supplements, Animal Feed Additive, Food Colorant, Pharmaceutical Industry, Colloid Production, Drying Medium.
Usage in Dietary Supplements
- Fortification and premix source: Due to its high elemental manganese content, it is used as an economical manganese source in multivitamin-mineral premixes and food fortification (typical dose is around 2 mg NRV).
- Powder/tablet formulations: It is used to provide manganese in powder blends and tablets because it is soluble and stable; its low cost is an advantage in large-scale premixes.
- Comparison with organic forms: It provides a higher Mn load compared to organic forms such as gluconate/chelates; organic forms may be preferred in some products regarding taste and gastric tolerance.
- Low-dose discipline: Due to the narrow safety margin of manganese, total Mn intake must be kept within safe levels even with the sulphate form; supplement doses are selected to be low.
Usage in the Food Industry
- Trace element additive for animal feed: It is a common trace element source used in animal feed premixes in the EU; EFSA FEEDAP determines maximum Mn levels per species in complete feed and references sulphate for bioavailability.
- Food fortification source: It is an authorized manganese form to be added to food supplements and fortified foods as a nutrient source.
Effects on Health
Manganese is a mineral that plays a role in many fundamental functions in the body. The main functions authorized/evaluated by the European Food Safety Authority (EFSA):
- Energy metabolism: Manganese contributes to normal energy-yielding metabolism (EFSA).
- Protection of bones: Manganese contributes to the maintenance of normal bones (EFSA).
- Formation of connective tissue: Manganese contributes to the formation of normal connective tissue (EFSA).
- Protection from oxidative stress: Manganese contributes to the protection of cells from oxidative stress (EFSA).
Usage Limits in Dietary Supplements
- Nutrient Reference Value (NRV): Manganese NRV is 2 mg (1169/2011).
- Tolerable Upper Intake Level (EFSA): EFSA has not determined a numerical classical UL; in its 2023 opinion, it defined 8 mg/day as a 'safe intake level' for adults (other groups 2–7 mg/day).
- Turkish legislation (TSE/TFK): Manganese is permitted under the TR Regulation; the NRV % must be declared on the label. The current guideline for maximum supplement amounts should be followed (not fabricated).
Excessive manganese can be neurotoxic (manganism); dose control is critical with the sulphate form due to its high Mn content.
