Manganese (as Manganese Citrate)
Also known as: Manganese Citrate, Mn, Manganese, Manganese chelate
Effective Dosage
1.8–2.3 mg daily (adequate intake levels; no clinical trial data from provided studies)
What the Science Says
Manganese is an essential trace mineral your body needs in tiny amounts to function properly. It acts as a cofactor for several enzymes involved in bone formation, carbohydrate and amino acid metabolism, and the production of superoxide dismutase — one of your body's key antioxidant enzymes. The citrate form is a chelated version intended to improve absorption compared to some other mineral salts, though no clinical studies from the provided data confirm a meaningful advantage in humans.
What It Doesn't Do
Won't build stronger bones on its own — bone health requires many nutrients working together. No evidence it boosts athletic performance or speeds up metabolism in people who aren't deficient. The 'citrate' form doesn't make it a superior or therapeutic ingredient — it's still just a trace mineral most people get enough of from food. No proven benefit for blood sugar control, joint pain, or cognitive function based on available data.
Evidence-Based Benefits
No papers were provided to support specific efficacy claims. Manganese is a recognized essential trace mineral involved in enzymatic processes, but no study abstracts were available to substantiate specific health outcomes or dose-response relationships for manganese citrate as a supplement form.
Weak EvidenceEffective at: No established dose from provided studies

Absorption & Bioavailability
Moderate — manganese citrate is generally considered better absorbed than inorganic forms like manganese sulfate, but absorption is still relatively low (3–8% in adults) and is inhibited by calcium, iron, and phytic acid from food. No provided studies confirm superiority of the citrate form.
Red Flags to Watch For
- Most adults already meet manganese needs through diet — deficiency is rare, making supplementation unnecessary for most people
- Excess manganese is neurotoxic: chronic high intake has been linked to neurological symptoms resembling Parkinson's disease (manganism)
- No papers were provided to support any specific health claim — all assessments here are based on general nutritional knowledge, not clinical trial data
- Supplements containing manganese often exceed the tolerable upper intake level when combined with dietary sources — check total daily intake
- People with liver disease may be at higher risk of manganese toxicity since the liver regulates excretion
