1. Promotes Bone Health
Manganese, despite its status as a trace mineral, assumes a valuable role in promoting bone health and potentially reducing the risk of osteoporosis and bone-related diseases.
Manganese's significance lies in its active involvement in collagen synthesis, an indispensable process vital for the formation and maintenance of the bone matrix. Collagen provides structural integrity to bones, enhancing their resilience and suppleness.
Additionally, manganese aids in bone mineralization by facilitating the accurate deposition of minerals such as calcium and phosphorus into bone tissue.
Furthermore, manganese contributes significantly to the formation of strong and healthy cartilage. It participates in the synthesis of glycosaminoglycans (GAGs) and proteoglycans, both key components of cartilage. These molecules help maintain the hydration and cushioning properties of the cartilage, thereby ensuring its resilience and shock-absorption capacity.
While further research is required to establish a direct correlation between manganese intake and osteoporosis prevention, several studies offer promising insights. For instance, a study published in the American Journal of Epidemiology reported that postmenopausal women with adequate manganese intake had greater bone density compared to those with lower manganese intake.

2. Enhances The Body's Antioxidant Defense
As part of the physiological processes of energy production, human cells are inherently tied to the use of oxygen. However, this metabolic activity, inadvertently produces reactive oxygen species (ROS), commonly known as free radicals, which can cause oxidative stress when their accumulation exceeds manageable levels.
Oxidative stress has been strongly implicated in the pathogenesis of a wide range of chronic and degenerative diseases, including cardiovascular disease, neurodegenerative disorders, autoimmune pathologies, early aging, and certain cancers.(1)
In its wisdom, the human body has developed a defense system to counteract the detrimental effects of free radicals. This defense is predominantly manifested through the endogenous synthesis of antioxidants, as well as its acquisition from external sources such as diet and supplementation. Notably, manganese emerges as an important player in this antioxidant arsenal.(1)
Manganese plays a crucial role by collaborating with the antioxidant enzyme superoxide dismutase (SOD), widely recognized as one of the most potent antioxidants naturally occurring in the human body. SOD acts primarily by converting superoxide, one of the most perilous free radicals, into smaller molecules believed to be harmless to human physiology.(2)
Manganese and SOD work diligently to proactively prevent and mitigate cellular damage caused by free radicals. This concerted effort represents an essential facet of the body's intricate antioxidant defense system, which is critical for preserving cellular health and overall well-being.

3. Helps in the Management of Blood Sugar Levels
Manganese may play a role in blood sugar regulation and diabetes management.
While manganese can be found in many parts of the body, it is particularly concentrated in the pancreas. This organ is responsible for the production of insulin, the hormone that coordinates the transport of glucose from the bloodstream to the cells. The proper secretion of insulin is critical for the body's optimal blood sugar regulation.
In one study, participants with low blood manganese levels had an increased risk of diabetes and kidney dysfunction, implying that manganese may play a role in glucose metabolism and diabetes management, though more research is needed to back up these claims.
In another study, researchers found that manganese levels were lower in diabetics than in healthy people. More research is needed, however, to determine if manganese deficiency contributes to the development of diabetes or if diabetes leads to low manganese levels.
Furthermore, a PubMed study showed that individuals with diabetes tend to have lower levels of the antioxidant enzyme manganese superoxide dismutase (MnSOD). This finding strengthens the link between reduced manganese levels and blood sugar disorders, thus offering interesting prospects for the management of diabetes.

4. May Help Relieve PMS Symptoms
Symptoms of premenstrual syndrome (PMS) typically start 1-2 weeks before your period and can include a spectrum of physical discomfort, such as pain and cramping, and emotional challenges like anxiety, anger, and mood swings, as well as behavioral symptoms like binge eating.
Although manganese is essential for various bodily functions, scientific evidence supporting its effectiveness in relieving PMS symptoms remains limited and inconclusive. Nevertheless, a few studies have shown promising results, suggesting that a combination of calcium and manganese may be effective in reducing PMS symptoms.
In one study involving ten women with regular menstrual cycle, those with low blood manganese levels experienced increased mood and pain-related symptoms regardless of how much calcium they were given.
Moreover, manganese serves as a cofactor for numerous enzymes involved in neurotransmitter synthesis, particularly those linked to the production of dopamine, and serotonin. These neurotransmitters have a significant impact on mood regulation, anxiety reduction, and emotional well-being, potentially contributing to the management of PMS symptoms.
5. May Play a Role in Thyroid Function
Manganese, although not the primary factor, does play a supporting role in thyroid function. It acts as a cofactor for enzymes involved in the conversion of the inactive thyroid hormone thyroxine (T4) into the active form, triiodothyronine (T3). This conversion is essential for the regulation of metabolism, the production of energy as well as the management of weight and appetite.
While iodine remains the crucial element for thyroid hormone production, manganese's participation in this enzymatic process indirectly contributes to maintaining the optimal functioning of the thyroid gland.
6. Supports Sexual and Reproductive Health
Manganese is essential for several enzymatic activities in the body, including those necessary for the production of cholesterol. Cholesterol, in turn, serves as a key precursor for the production of reproductive hormones such as estrogen, progesterone and testosterone.(3)
Furthermore, manganese is thought to be present in the hypothalamus, a vital area of the brain responsible for orchestrating the complex mechanisms of reproductive hormone production. It oversees the synthesis of key sex hormones, namely estrogen and testosterone, both of which have a considerable impact on human reproductive physiology.
7. Reduces Inflammation
Manganese, owing to its powerful antioxidant properties and its role within the enzyme superoxide dismutase (SOD), holds the potential to reduce inflammation, particularly when combined with glucosamine and chondroitin.
A study conducted by the National Institute of Health (NIH) suggested that SOD could serve as a valuable therapeutic agent in the treatment of inflammatory diseases.
Manganese is thought to ease the symptoms of osteoarthritis when combined with glucosamine and chondroitin, both considered important structural components of cartilage, the protective cushioning of the joints.
Osteoarthritis, the most prevalent form of arthritis, is characterized by discomfort, pain, stiffness, and even cartilage breakdown, with inflammation believed to be a key contributor to its pathogenesis.
A PubMed study involving 93 individuals with osteoarthritis revealed that 52% experienced a noticeable improvement in their symptoms after four to six months of taking manganese, glucosamine, and chondroitin supplements. However, it’s important to note that these improvements were primarily observed in individuals with mild to moderate osteoarthritis, while those with severe osteoarthritis reported limited or no benefits.
Nevertheless, in another 16-week study involving 34 males with chronic pain and degenerative joint disease demonstrated significant symptom relief following taking the supplement, raising the possibility of wider use of this supplement in similar cases in the future.
