Manganese is essential for bone formation, metabolism, and enzyme function, which are proteins that speed up chemical reactions. It helps process carbohydrates, amino acids, and cholesterol, supports wound healing, and boosts the immune system, which defends against infections.
You can get manganese from nuts, seeds, whole grains, and leafy green vegetables. Some seafood and fortified cereals also contain manganese. A balanced diet with these foods ensures adequate intake.
Manganese deficiency can lead to impaired growth, bone abnormalities, and reduced fertility. Symptoms include poor bone formation, slow wound healing, and skin problems. Groups at risk include those with poor diets, pregnant women, and the elderly.
The daily requirement for adult men is about 2.3 mg, and for women, it's about 1.8 mg. Pregnant and breastfeeding women need slightly more. The upper limit for safe intake is 11 mg per day for adults.
Manganese supplements can interact with certain medications, like antibiotics, affecting their absorption. Excessive intake can cause nausea, vomiting, and neurological issues. People with liver disease are more vulnerable to toxicity. Always consult a healthcare provider before taking supplements.

* DV means Daily Value. It’s a number set by the U.S. Food and Drug Administration (FDA) to show how much of a nutrient you should get each day. For example, the Daily Value for calcium is 1,300 mg for adults and kids aged 4 and older. Food labels must show how much calcium they contain. If a food gives you 20% or more of your daily calcium need, it’s considered a high source. Even if a food gives less, it can still be part of a healthy diet.
