If you practice a plant-based diet, then you have been consuming manganese regularly! While it may not be as popular as current hot topic nutrients — think healthy fat, protein, vitamin C, and enzymes — this underrated trace mineral is naturally present in a variety of fruits, veggies, and grains that you have been eating for years.
While your body needs only small amounts, manganese is quite important for overall bodily functions. Not only does it help with the normal functioning of your brain, but it plays an integral role in your body’s nervous and enzyme systems. It’s broken down and stored in your liver, kidney, pancreas, and bones, meaning it’s basically everywhere in your body, and you didn’t even know it!
What is Manganese?
First off, it’s important to note that manganese is a trace mineral, which means “your body needs it in small amounts,” versus other nutrients such as fiber, protein, or calcium. Even though it’s a trace mineral, manganese is also categorized as an essential nutrient. This means that it’s found in plant-based foods, particularly in “seeds and whole grains, as well as in smaller amounts in legumes, beans, nuts, leafy green vegetables, and tea.”
Like many other minerals, manganese doesn’t play just one role in the body. It helps with “numerous chemical processes, including synthesis of nutrients like cholesterol, carbohydrates, and proteins,” and it’s an important part “in the formation of bone mass and helps balance hormones naturally.” Yet, its duties don’t stop there! Manganese is part of various “vital functions, including nutrient absorption, production of digestive enzymes, bone development and immune-system defenses,” and helps balance calcium and phosphorous levels.
Confused? Manganese Versus Magnesium
While at first glance they may look the same, manganese and magnesium are separate minerals that play similar roles in the body.
Manganese, as mentioned, “helps regulate your blood sugar and supports the health of your nervous system,” as well as aids in the absorption of calcium, the breaking down of carbohydrates and fats, and the synthesis of bones, “endocrine hormones, connective tissue, the proteins necessary for blood coagulation and the enzyme superoxide dismutase, a powerful antioxidant.”
On the other hand, while magnesium also “plays a role in bone health and energy metabolism,” it also “triggers the activity of over 300 enzymes, helps maintain the electrochemical balance your neurons and muscles need to work and aids in the production of DNA and RNA.”
You need both of these minerals for a healthy, functioning body!
Deficiency versus Overconsumption
Getting the goldilocks portion of manganese is not a difficult task. Many plant-based, popular foods have appropriate doses, plus the “body tightly regulates the amount of manganese it holds through levels of absorption and excretion,” meaning that humans naturally “maintain stable tissue levels of manganese in most cases.”
Although rare, manganese deficiencies tend to be caused by an imbalanced diet, primarily one that lacks foods rich in manganese such as “sprouted grains, legumes or beans, certain nuts, and seeds.” Symptoms of a manganese deficiency include osteoporosis or weakened bones, anemia, chronic fatigue syndrome, poor immunity, worsened PMS symptoms, hormonal imbalances, impaired glucose sensitivity, problems with fertility and even infertility, and drastic changes in digestion and appetite.
On the other hand, when you consume too much manganese, it may be even more dangerous to your body.
When manganese is overconsumed, it becomes toxic, especially “during development years when the brain is still forming.” If you are consuming manganese past the point that your body needs it, the mineral will begin to accumulate in the “central nervous system” which may cause “birth defects and cognitive problems.”
With that said, it’s pretty difficult to consume too much manganese from your diet. Manganese is not only a trace mineral — found in small amounts — but only a “small percentage of dietary manganese is even actually absorbed, and the rest is excreted very rapidly into the gut via bile and then excreted.” Those that suffer from manganese toxicity may have “existing liver, gut or digestive problems” or are taking a supplement without proper professional guidance from a primary care physician or nutritionist.
Health Benefits of Manganese
Once you’re comfortable with your manganese consumption — easily accomplished on a plant-based diet or with the help of a nutritionist or dietician — it’s time to reap those wonderful benefits! Proper manganese consumption — women 19 and over are recommended 1.8 milligrams daily, and men over 19 are recommended 2.3 milligrams daily — has been linked to the prevention of osteoporosis, reduced risk of diabetes, reduced severity of premenstrual syndrome symptoms, and helps with enzyme and antioxidants functions.
Boosted Bone Health
One of the glaring positive benefits of consuming manganese is not only better overall bone health, but the relationship to osteoporosis prevention. Osteoporosis — meaning porous bones — “is a disease in which the density and quality of bone are reduced,” eventually degrading the bone into a fragile state that drastically increases the risk of fracture.
Manganese generally goes hand-in-hand with bone-boosting minerals “including calcium, zinc and copper,” which band together to “help reduce bone loss, especially in older women who are more susceptible to bone fractures and weak bones.” Plus, as manganese “helps with the formation of bone regulatory hormones and enzymes involved in bone metabolism,” proper consumption of this trace mineral will help prevent osteoporosis later on in life.
Reduced PMS Symptoms
We’re all looking for that magic cure to help manage those horrible premenstrual syndromes. While the experience ranges from woman to woman, most of the symptoms are similar, including cramps, headaches, drastic hormonal mood swings, bloating, and acne.
Luckily, manganese may be able to help out with this! In particular, when consumed with calcium, it has been linked to improved PMS symptoms such as “tenderness, muscle pain, anxiety, mood swings, and trouble sleeping.”
Proper Enzyme and Antioxidant Functions
This may not be a health benefit that you readily see or experience — such as improved PMS symptoms — yet this one takes the cake of importance! As mentioned, manganese plays a crucial role in many enzyme functions, “including arginase, glutamine synthetase, and manganese superoxide,” which “work as antioxidants in the body, helping lower levels of oxidative stress and inflammation that can lead to heart disease or cancer.”
While all of these enzyme functions are important, it’s also important to note that “superoxide dismutase is sometimes called the ‘primary’ or ‘master antioxidant’ since it’s especially powerful at reducing inflammation, pain and bodily stress that can lead to numerous chronic diseases.”
Reduced Risk of Diabetes
Manganese not only reduces the risk of diabetes, but researchers have discovered that proper consumption can damage the disease. First off, manganese is necessary for the production of a digestive enzyme that is integral in gluconeogenesis — the “conversion of protein’s amino acids into sugar and the balance of sugar within the bloodstream.” Research is still underway regarding the exact mechanism of this relationship, yet it has revealed that “manganese has been shown to help prevent overly high blood sugar levels that can contribute to diabetes.”
5 Plant-Based Sources of Manganese
Barring preexisting conditions, manganese is one of those wonderful minerals that you don’t have to regulate! Simply integrate a balanced plant-based into your life and BAM, you’re getting the appropriate amounts. With that said, it’s always smart to know where to get certain nutrients. Here are some of the richest natural plant-based sources of manganese!
