What Types of Manganese Dietary Supplements Are Available?

Manganese is available in many multivitamin/multimineral and other dietary supplements. Supplements contain many forms of manganese, such as manganese sulfate and manganese aspartate. Scientists don't know whether any form of manganese in supplements is better than any other form.

Am I Getting Enough Manganese?

People who eat healthily get enough manganese from the foods they eat.

What Happens If I Don't Get Enough Manganese?

Manganese deficiency is rare. A deficiency can cause the following symptoms:

  • Weak bones and growth failure in children
  • Skin rashes and loss of hair color in men
  • Mood changes and worse-than-usual premenstrual pain in women

What Are Some Effects of Manganese on Health?

Scientists are studying manganese to understand how it affects health. Here are some examples of what this research shows.

Bone health:  Manganese, along with other minerals and vitamins, is needed for healthy bone formation. However, more research is needed to understand manganese's role in maintaining or improving bone health.
Diabetes:  We need manganese to help break down starches and sugars. However, its effect on diabetes risk is unknown. More research is needed to understand whether manganese plays a role in the development of diabetes.

Can Manganese Be Harmful?

Studies have not shown any harm from manganese in foods and beverages. However, some people have developed manganese toxicity by consuming water containing very high levels of manganese. Another cause of manganese toxicity is inhaling large amounts of manganese dust from welding or mining operations.

Symptoms of manganese toxicity include tremors, muscle spasms, hearing problems, mania (abnormally elevated mood), insomnia, depression, loss of appetite, headaches, irritability, fatigue, and mood changes.

People should not consume more manganese than the upper limits from food, beverages, or dietary supplements unless their healthcare provider recommends it.

Upper daily limits for manganese include intakes from all sources (food, beverages and supplements) and are listed below.

Age Upper Limit
From birth to 6 months Not established
Babies from birth 7-12 Not established
Children 1-3 years old 2 mg
Children 4-8 years old 3mg
Children aged 9-13 6mg
Young people aged 14-18 9 mg
Adults 11 mg
Pregnant and breastfeeding teenagers 9 mg
Pregnant and breastfeeding adults 11 mg

Does Manganese Interact with Medications or Other Dietary Supplements?

Manganese is not known to interact or interfere with any medications.

Tell your doctor, pharmacist, and other health care providers about the dietary supplements and prescription or over-the-counter medications you take. They can tell you whether dietary supplements interact with your medications or whether medications affect your body's ability to absorb, use or break down nutrients such as manganese.

Manganese and Healthy Nutrition

People should get most of their nutrients from food and drink. Foods contain vitamins, minerals, dietary fiber and other components that benefit health. In some cases, fortified foods and dietary supplements are useful when it is not possible to meet the needs of one or more nutrients (for example, during certain life stages, such as pregnancy).
