![]() ![]() It might even have negative side effects on brain function, motor skills, memory, and mood ( 30, 31, 32, 33). Getting too muchīeing exposed to large amounts of manganese in the environment, such as from welding fumes or contaminated water, can be extremely dangerous. Only use manganese supplements under the supervision of a healthcare professional ( 29). Too much or too little can have detrimental side effects ( 26, 28, 29).īecause manganese can be toxic in large amounts, it’s important to be especially careful with supplements. It’s also clear that maintaining normal blood levels of the nutrient is important. Manganese is an essential nutrient that humans need to survive and thrive. Not only does manganese play a role in brain development, but maintaining normal blood levels of the mineral may prevent neurological conditions like Parkinson’s disease and epilepsy ( 24, 25, 26, 27). Though more research is needed to understand the exact relationship, some recent studies have observed relationships between blood pressure and levels of manganese in the blood and urine ( 22, 23). Multiple human studies have found associations between higher levels of dietary manganese intake and a lower risk of type 2 diabetes among adults ( 18, 19, 20, 21). It may help prevent bone loss in older adults ( 16, 17). In childhood, manganese supports bone growth. Getting enough manganese on a regular basis has also been linked to a number of other health benefits, including: BenefitsĪs an antioxidant, manganese discourages cellular oxidation and may help prevent chronic disease. MnSOD’s ability to prevent damage to cells means it likely plays an important role in the prevention of cancer and other chronic diseases ( 8, 11, 14, 15). Scientists are still working to uncover the exact ways it does so. This antioxidant is responsible for protecting your cellular machinery from getting damaged by a chemical process called oxidation ( 8, 11, 12, 13). In fact, manganese is a key component of a chemical compound known as manganese superoxide dismutase (MnSOD). ![]() It also plays a part in antioxidant activity throughout your body ( 7, 8, 10). Manganese is essential for many of the small reactions that take place inside your cells, such as helping enzymes carry out bodily activities, including digestion, metabolism, growth, reproduction, and energy production ( 6, 7, 8, 9). Though manganese is a trace mineral your body needs only in small amounts, its functions are widespread and important. The chart below compares a few more properties of manganese and magnesium ( 2, 3, 4, 5). When people take too much of these, it’s usually from supplements or over-the-counter drugs like antacids or laxatives in the case of magnesium ( 2, 3). Thus, it’s important to use caution if you’re taking supplements or have direct exposure to either ( 2, 3).įortunately, it’s hard to get too much of the minerals from diet alone. What’s more, manganese and magnesium both have the chemical structure of metals.īoth can also have toxic effects in large amounts. For example, they’re both found in nuts, legumes, leafy vegetables, and whole grains ( 2, 3). Still, the two minerals have similarities. On a daily basis, your body needs hundreds of times more magnesium than manganese ( 1). Manganese is considered a trace element or a micromineral - you only need it in small amounts ( 1). One of the main practical differences between manganese and magnesium is the amount of each that you need to consume each day.
