FAQ
What exactly is manganese and why does my body need it?
Manganese is an essential mineral and a trace mineral that the body needs to perform several vital functions. It acts as a chemical catalyst in your system, meaning manganese is a cofactor for many enzymes. Specifically, manganese plays a role in bone formation, blood clotting, and reducing inflammation. Because manganese is also involved in metabolism, it helps your body process carbohydrates and proteins effectively.
What are the most common health benefits of manganese?
The health benefits of manganese are quite impressive! One of its most critical roles is as a component of manganese superoxide dismutase, which is a powerful antioxidant that protects your cells from damage. Additionally, manganese helps support strong bone health and skeletal integrity. For those curious about metabolic health, manganese supplementation may assist in regulating blood sugar, as manganese is involved in insulin secretion and glucose balance.
Which foods are considered the best sources of manganese?
You can find plenty of dietary manganese in plant-based foods. Some of the best sources of manganese include whole grains, legumes, nuts, and leafy green vegetables. For example, hazelnuts, pecans, and spinach are very high in manganese. By eating a varied diet that includes these items, most people can easily get enough manganese without needing a specialized manganese supplement.
How can I tell if I have low manganese levels?
While a true manganese deficiency is rare in humans, low manganese levels can lead to symptoms like poor bone health, skin rashes, and even changes in hair color. To determine whether manganese levels are sufficient, a healthcare provider might order a test to check your blood manganese level or plasma manganese levels. If the levels of manganese are consistently low, it may impact your overall health and metabolism.
What should I know about taking manganese supplements?
If you decide to take manganese supplements, you will often see them in forms like manganese gluconate, manganese sulfate, or manganese aspartate. It is important to remember that manganese is absorbed in the small intestine, and its absorption can be affected by other minerals. For instance, iron and manganese compete for the same transporters, so taking manganese in high doses might interfere with your iron levels. Experts often suggest you take manganese supplements at least two hours apart from other major mineral supplements.
Is it possible to have too much manganese in the body?
Yes, excess manganese can be harmful. While it is difficult to get a high manganese intake from food alone, manganese toxicity usually occurs from environmental manganese exposure, such as inhaling manganese dust in industrial workplaces. Over time, manganese can build up in the brain, leading to serious neurological issues. Monitoring blood levels of manganese is crucial for anyone exposed to manganese through their occupation or through a high manganese concentration in drinking water.
How does the National Institutes of Health define a safe amount of manganese?
The National Institutes of Health has established an Adequate Intake (AI) level to ensure people get adequate manganese for their daily needs. For adult men, the recommended amount of manganese is 2.3 mg per day, while for adult women, it is 1.8 mg. They also set a Tolerable Upper Intake Level (UL) of 11 mg of manganese daily for adults to prevent adverse effects and ensure the safe excretion of manganese from the body.
What is the relationship between manganese and type 2 diabetes?
Research, including studies like the National Health and Nutrition Examination Survey, has looked into how manganese levels and type 2 diabetes are connected. Since manganese plays a part in the way your body handles sugar, low manganese has been linked to impaired glucose tolerance. However, scientists are still working to determine whether manganese supplementation can directly improve outcomes for those living with diabetes.
Are there any specific health risks associated with manganese in drinking water?
Yes, a high manganese concentration in drinking water can pose a health risk, particularly for infants and young children whose manganese metabolism is still developing. If manganese concentrations are too high in a public water supply, it can lead to higher manganese levels in the blood, which may affect cognitive development. It is always a good idea to check your local water quality reports for the manganese content if you use a private well.
Who should be cautious about high doses of manganese?
Individuals with chronic liver disease should be very careful with high doses of manganese because the liver is primarily responsible for the excretion of manganese from the body. If the liver isn’t functioning correctly, manganese levels in the body can rise to dangerous levels. Additionally, because manganese and calcium or iron can interact, anyone with existing mineral deficiencies should consult a professional before starting manganese supplementation to avoid any side effects of manganese.
