How much Manganese should I take daily?

Manganese is an essential nutrient required for various biological processes in the human body. The daily intake of manganese can vary based on dietary habits and environmental exposure.

Studies have shown that the daily intake of manganese through diet and environment typically ranges from 0.67 to 4.99 mg, with an average around 2.21 mg, which is close to the lower bound of the recommended limit of 2-5 mg.
The average dietary manganese intake in the German population is about 2.8 mg/day for a person of 70 kg body weight, which falls within the recommended intake range of 2-5 mg per person per day.
A metabolic balance study suggests that the theoretical mean dietary level of manganese required for positive balance in young men is 3.5 mg/day or 50 micrograms/kg.
An optimal manganese dose for adult patients undergoing home parenteral nutrition may be 1 micromol/d, which is equivalent to approximately 0.055 mg/day, to maintain normal whole-blood manganese concentrations.
A safe level of intake of 8 mg/day for adults has been established, with a range between 2 and 7 mg/day for other population groups, indicating that this is the highest level of intake without adverse effects.
Manganese intake from food supplements at doses of 1, 5, or 10 mg per day may be associated with increased risk of negative health effects, and the previous maximum limit for manganese in food supplements was 5 mg per daily dose.
In Korea, the daily manganese intake was estimated to be 5.2 mg for males and 4.1 mg for females, with some individuals exceeding the tolerable upper intake level.
The mean daily dietary manganese intake in Belgium was found to be 3.1 mg/day, which is within the recommended intake ranges.

In conclusion, the daily intake of manganese for adults typically falls within the range of 2-5 mg, which aligns with the recommended limits. Some studies suggest a safe upper level of 8 mg/day for adults, while others indicate potential risks associated with intake from food supplements. It is important to consider both dietary sources and supplements when assessing total manganese intake to avoid exceeding the tolerable upper intake levels.

Daily intake of manganese by the adult population of Mumbai.

The daily manganese intake of the adult population of Mumbai is closer to the lower bound of the recommended limit of 2-5 mg, with food being the predominant source.

Dietary Manganese Exposure in the Adult Population in Germany - What Does it Mean in Relation to Health Risks?

Dietary manganese intake in the German population aged 14-80 years is within the recommended range of 2-5 mg per person and day, but there is limited evidence on potential health risks when intake amounts are exceeded.

Metabolic balance of manganese in young men consuming diets containing five levels of dietary manganese.

The theoretical mean dietary manganese level for positive balance in young men is 3.5 mg/d or 50 micrograms/kg, with a range of dietary intakes of 2,6, 1,21, 3,79, and 2.65 mg/d.

Evaluation of indexes of in vivo manganese status and the optimal intravenous dose for adult patients undergoing home parenteral nutrition.

The optimal dose of manganese for adult patients undergoing home parenteral nutrition is 1 micromol/d, with whole-blood manganese concentrations and MRI intensity and T(1) values as useful indexes.

Scientific opinion on the tolerable upper intake level for manganese

The EFSA Panel on Nutrition, Novel Foods, and Food Allergens recommended a safe manganese intake of 8 mg/day for adults under 18 years and 2-7 mg/day for other population groups, but the risk of adverse effects increases with higher intake.

Assessment of Dietary Intake of Manganese in Relation to Tolerable Upper Intake Level

Manganese intake is adequate in Norway, with a maximum daily intake of 10 mg in food supplements, but excessive intake can cause permanent neurological disorders like manganism.

Estimation of manganese daily intake among adults in Korea

Korean adults consume 148.8% of the adequate manganese intake, with males consuming more manganese, and both males and females meeting the tolerable upper intake level.

Daily dietary manganese intake in Belgium, using duplicate portion sampling

The mean manganese intake in Belgium (3.11.1 mg/day) is similar to levels found in other countries and within recommended intake ranges recommended by WHO/RDA and NRC, USA.

Dietary standards for manganese: overlap between nutritional and toxicological studies.

Manganese toxicity is primarily protected by low absorption and rapid elimination by the liver, with serum manganese concentrations being the best biomarker for monitoring insufficient manganese intake and excessive exposure.

Oral manganese intake estimated with dietary records and with direct chemical analysis.

Dietary records and tables of manganese contents give an estimated oral dose 22% higher than direct chemical analysis, making it a less accurate method for estimating manganese intake.
