Manganese

IN THIS ARTICLE

Are there any interactions with medications?



Antibiotics (Quinolone antibiotics)
Interaction Rating: Moderate Be cautious with this combination.
Talk with your health provider.

Manganese might decrease how much antibiotic the body absorbs. Taking manganese along with some antibiotics might decrease the effectiveness of some antibiotics. To avoid this interaction, take manganese supplements at least one hour after antibiotics.

Some of these antibiotics that might interact with manganese include ciprofloxacin (Cipro), enoxacin (Penetrex), norfloxacin (Chibroxin, Noroxin), sparfloxacin (Zagam), trovafloxacin (Trovan), and grepafloxacin (Raxar).



Antibiotics (Tetracycline antibiotics)
Interaction Rating: Moderate Be cautious with this combination.
Talk with your health provider.

Manganese can attach to tetracyclines in the stomach. This decreases the amount of tetracyclines that can be absorbed. Taking manganese with tetracyclines might decrease the effectiveness of tetracyclines. To avoid this interaction, take manganese two hours before or four hours after taking tetracyclines.

Some tetracyclines include demeclocycline (Declomycin), minocycline (Minocin), and tetracycline (Achromycin).

Dosing considerations for Manganese.

The following doses have been studied in scientific research:

BY MOUTH:
  • For weak bones (osteoporosis): 5 mg of manganese per day combined with 1000 mg of elemental calcium, 15 mg of zinc, and 2.5 mg of copper.
  • No recommended dietary allowances (RDA) for manganese have been established. When there are no RDAs for a nutrient, the Adequate Intake (AI) is used as a guide. The AI is the estimated amount of the nutrient that is used by a group of healthy people and assumed to be adequate. The daily Adequate Intake (AI) levels for manganese are: infants birth to 6 months, 3 mcg; 7 to 12 months, 600 mcg; children 1 to 3 years, 1.2 mg; 4 to 8 years 1.5 mg; boys 9 to 13 years, 1.9 mg; boys 14 to 18 years, 2.2 mg; girls 9 to 18 years, 1.6 mg; men age 19 and older, 2.3 mg; women 19 and older, 1.8 mg; pregnant women age 14 to 50, 2 mg; breastfeeding women, 2.6 mg.
  • Tolerable Upper Intake Levels (UL), the highest level of intake at which unwanted side effects are not expected, for manganese have been established. The daily ULs for manganese are: children 1 to 3 years, 2 mg; 4 to 8 years, 3 mg; 9 to 13 years, 6 mg; 14 to 18 years (including pregnant and breastfeeding women), 9 mg; for adults 19 years and older (including pregnant and breast-feeding women), 11 mg.
