Manganese is an essential mineral that plays a critical role in various bodily functions, including brain function, metabolism, and bone health.

However, excessive intake of manganese, either through diet or supplementation, can lead to adverse health effects, including heart problems.

What is Manganese?

Manganese is a mineral that is required in small amounts for many bodily functions. It is found naturally in foods such as nuts, whole grains, and leafy vegetables. Manganese is also available as a dietary supplement.

What are the Effects of Too Much Manganese on the Body?

Although manganese is necessary for several bodily functions, having too much of it can cause negative health consequences. The potential effects of excessive manganese intake include:.

1. Neurological Symptoms

One of the most common symptoms of manganese toxicity is neurological symptoms. These include tremors, slurred speech, and difficulty walking.

Long-term exposure to high levels of manganese can also cause Parkinson’s-like symptoms, such as rigid muscles and slow movements.

2. Respiratory Problems

High levels of manganese can cause respiratory problems, including coughing and shortness of breath. Manganese toxicity can also lead to permanent lung damage.

3. Skin Problems

Exposure to high levels of manganese can cause skin rashes and other skin problems. This may be due to the ability of manganese to bind with sulfur in the body, leading to the formation of compounds that can cause skin irritation.

4. Cardiovascular Effects

Excessive manganese intake has also been linked to cardiovascular effects. Studies have found that high levels of manganese can contribute to an increased risk of heart problems, including hypertension and arrhythmia.

5. Liver Damage

High levels of manganese can also cause liver damage. Studies have found that long-term exposure to high levels of manganese can lead to cirrhosis of the liver.

How Much Manganese is Too Much?

The daily recommended intake of manganese for adults is 1.8-2.3 mg per day. However, the safe upper limit for manganese intake has not been established.

It is generally recommended that individuals do not exceed 11 mg per day of manganese from foods and supplements combined.

How to Reduce Manganese Intake?

If you are concerned about your manganese intake, there are several ways to reduce it:.

Avoid taking manganese supplements unless prescribed by a healthcare professional.
Eat a well-balanced diet that does not rely heavily on processed foods.
Avoid drinking water from sources that are high in manganese, such as well water.
Avoid living or working in environments where there is excessive manganese exposure, such as mining or smelting operations.

The Bottom Line

While manganese is an essential mineral, having too much of it can cause negative health effects, including cardiovascular problems. If you are concerned about your manganese intake, talk to your healthcare provider about ways to reduce your exposure.
