Q.

What is the recommended dosage for Manganese?

 

Answers From Experts & Organizations (1)

Medical Reference
A.
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 breastfeeding women), 11 mg.
