Manganese and Multivitamin have at most a minor documented interaction. Count manganese from food and all products. Use EFSA’s 8 mg/day safe level as a population reference, not a supplement allowance. If you have liver disease, check manganese-containing supplements with your clinician before use.
Overlap alone is not a clinical interaction. The total matters for people with liver disease, who clear manganese less well and can accumulate it.
Check how much manganese every product contains. EFSA’s 2023 safe level for total adult intake is 8 mg/day; EFSA could not establish a UL. The US adult UL is 11 mg/day. Count food as well as supplements.
What to do: Count manganese from food and all products. Use EFSA’s 8 mg/day safe level as a population reference, not a supplement allowance. If you have liver disease, check manganese-containing supplements with your clinician before use.
Dose matters: Total adult manganese intake above EFSA’s safe level of 8 mg/day, above the US UL of 11 mg/day, or manganese supplementation in someone with liver disease needs review. The EFSA value is not a toxicity threshold.. Minimal risk: Lower total manganese exposure in an adult without liver disease; assess food and all supplements. Being below a reference value does not establish individual safety..
